Add a New Topic
- A.L.E.R.T.: A roadside tester screening device. An approved screening device Model J3A formerly used in Ontario.
- absorption: Ethanol, drinking alcohol, disappears in the mouth, the stomach and the small intestine and enters the blood.
Graph of blood alcohol concentration over time as a 155 lb. male consumes 4 341 ml. beers with a full stomach. Food has slowed this absorption down. Without food the absorption would be quicker.
Notice the time 1900 to 2200. At first there is absorption of alcohol through the mouth, stomach, and intestines and into the blood. Almost immediately elimination begins as the liver starts to metabolize the alcohol. The blood alcohol concentration rises during this absorptrion phase because absorption greatly exceeds elimination.
After that there is a plateau where the BAC stays fairly constant or bounces up and down a bit. Plateau absorption rate equals elimination rate approximately but stomach flap sometimes opens to let contents into intestine. Some people may plateau for 2 hours.
The elimination phase starts about 2300. elimination would have continued through 0100 and beyond at a rate of about 10 to 20 mg/100mls per hour. Back calculations work ONLY in the elimination phase, if at all.
Don't use this information to calculate your own BAC, that could be dangerous. The BAC equivalent of each bottle of beer varies from individual to individual and varies with weight, gender, and body shape.
- accuracy: Accuracy has to do with whether or not a breath test instrument's analysis of blood alcohol concentration is the same as or similar to the subject's true blood alcohol concentration. If a person's true blood alcohol concentration is 100 mg/100mLs then an accurate breath test instrument is going to provide an analysis of near 100 mg/100mLs.
Precision has to do with whether the breath test instrument will give the same or similar result multiple times for the same subject, assuming that the person's blood alcohol concentration isn't changing over time (which it probably is).
See the Target Analogy.
- acetone: An interferent that sometimes looks to a breath instrument like ethanol during breath tests. When an IR breath test instrument analyzes substances in the sample chamber, IR light is absorbed by acetone at some of the same wavelengths as ethanol. If acetone is present, the instrument which uses only two or three filters (one for each wavelength) may analyze acetone as if it were ethanol. Such instruments are generally designed to notice, if acetone is present, that the ratio of absorption of IR at two different wavelengths isn't the ratio that it is supposed to be, triggering an error message. The instruments, however, are preset to not notice interferents below a certain threshold. The problem becomes much more difficult if there is a mix of ethanol, acetone, and other stuff. There are also problems if the instrument attempts to subtract the acetone reading from the combined acetone and ethanol reading. Acetone is found in many products such as nail polish remover.
- Admissibility of Physicals and ASD Prior to Rights: Assume that a police officer uses a p.b.t., screening device, or physical tests at roadside for the purpose of determining whether or not he or she has reasonable grounds to arrest a person for drunk driving. If the tests are compelled or if the driver willingly complies without first being warned that these tests will be used against his or her interests or without first being given an opportunity to consult with legal counsel, is it fair that these tests be used against the driver when it comes time for Court. The officer must make quick and important decisions at roadside as to whether or not to arrest. Those decisions need to be based on quickly obtained information. But should this urgent information ultimately be used against the driver at the criminal trial. Does compelling an individual to help the police violate basic rights?
- aggravating circumstances: The circumstances of the offence that make this particular case worse than an ordinary example of this offence. In impaired driving cases, high BAC readings, bad driving, high speeds, danger to the public, child in the car, an accident or near accident, injuries to a victim, or some combination of these may be aggravating circumstances.
- alcohol: Ethanol (drinking alcohol)is produced from sugar by fermentation of grains. However, there are lots of other alcohols - molecules with a hydroxyl OH attachment. Other non-drinking alcohols include methyl alcohol (methanol) and isopropanol.
- approved container: A method of retaining a portion of a breath sample for later independent testing.
- Approved Instrument: An instrument that is designed to receive and make an analysis of a sample of the breath of a person in order to measure the concentration of alcohol in the blood.
- approved screening device: roadside tester, PBT, P.B.T., minimal intrusion on driver, rough idea of blood alcohol concentration, pass, warn, fail. In order to minimize police interference with motorists, police will sometimes use a mobile roadside device at R.I.D.E. or other holiday programs to stop motorists and perform a quick check of blood alcohol concentration through the use of a roadside tester.
- arbitrary detention: The detention of a person despite a lack of evidence or likelihood that they have committed a crime.
- As Soon as Practicable: Breath tests are obviously never seized at exactly the same point in time as the moment when the alleged drunk driving occurred. The analysis of breath at the time of the breath tests will almost always have a different result than the subject's true blood alcohol concentration at the time of driving, because of the phenomena of absorption, distribution, and elimination of alcohol in the human body over time. Different jurisdictions use different methods to solve this problem. How does your jurisdiction deal with this problem? Some jurisdictions require the breath tests to be taken "as soon as practicable".
- BAC: Blood Alcohol Concentration, alcohol concentration in the bloodstream. Sometimes expressed as milligrams of alcohol per 100 millilitres of blood (mgs/100mLs), millimoles per litre (mmol/L), or grams of alcohol per 100 mls of blood (grams of alcohol per 210 litres deep lung air). Not the same thing as Breath Alcohol Concentration (BrAC).
- blood demand: In some jurisdictions a police officer may demand a sample of a driver's blood for blood tests for the presence and concentration of alcohol or a drug.
- blood tests: In some jurisdictions police may make a blood demand for a sample of a person's blood in order to determine the concentration of alcohol or a drug in a driver's body.
- bolus drinking: Administering a very large quantity of alcohol quickly through the mouth sometimes using a funnel. The concentration of alcohol in the blood will rise very significantly but absorption may be delayed depending on food, stomach health, and type of beverage. Very dangerous.
It may be an explanation in some unique cases as to why breath instrument readings exceed true BAC at time of driving.
- calibration: VIM 2012
2.39 (6.11) calibration
operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication
NOTE 1 A calibration may be expressed by a statement, calibration function, calibration diagram, calibration curve, or calibration table. In some cases, it may consist of an additive or multiplicative correction of the indication with associated measurement uncertainty.
NOTE2 Calibration should not be confused with adjustment of a measuring system, often mistakenly called “self-calibration”, nor with verification of calibration.
NOTE 3 Often, the first step alone in the above definition is perceived as being calibration.
2.39 (6.11) étalonnage, m
opération qui, dans des conditions spécifiées, éta- blit en une première étape une relation entre les valeurs et les incertitudes de mesure associées qui sont fournies par des étalons et les indications correspondantes avec les incertitudes associées, puis utilise en une seconde étape cette information pour établir une relation permettant d'obtenir un résultat de mesure à partir d'une indication
NOTE1 Un étalonnage peut être exprimé sous la forme d'un énoncé, d'une fonction d'étalonnage, d'un dia- gramme d'étalonnage, d'une courbe d'étalonnage ou d'une table d'étalonnage. Dans certains cas, il peut consister en une correction additive ou multiplicative de l'indication avec une incertitude de mesure associée.
NOTE 2 Il convient de ne pas confondre l'étalonnage avec l'ajustage d'un système de mesure, souvent appelé improprement «auto-étalonnage», ni avec la vérification de l'étalonnage.
NOTE 3 La seule première étape dans la définition est souvent perçue comme étant l'étalonnage.
- calibration of approved screening device: Manufacturers, entities responsible for setting national or state or provincial breath and blood standards, and individual police services appear to have different standards or no standards for frequency of calibration checks and if necessary re-calibration of screening devices aka roadside testers. It seems unfair that drivers should be subjected to testing if the device is not known to be reliable. Perhaps police, lawyers, and the Courts should be consulting the manufacturer's operating manual (R. v. Bernshaw)and the relevant national or provincial standards before relying on the accuracy of these devices. Assuming we are speaking about fuel cell devices, their calibration is very different from IR devices.
- can I get a work permit to drive?: Zero tolerance for DUI convictions means in Canada a minimum one year driving prohibition. Some provinces however have prohibitions shortened with interlock devices.
- can u go to prison for having no driving licence?: Driving while suspended or prohibited usually results in jail. Driving with no licence is still serious but less serious than driving while on a Court order or a licence suspension not to drive.
- Care or Control: charge of or power to direct or command, Some use of the car or its fittings and equipment, or some course of conduct associated with the vehicle which would involve a risk of putting the vehicle in motion so that it could become dangerous
- Carter defence: Sometimes a person accused of a per se over 80 offence tells their lawyer what they drank and when and the lawyer hires a toxicologist to calculate the person's estimated blood alcohol concentration at the time of driving. If the evidence of the driver is believed and the toxicologist's expert evidence is accepted and that evidence contradicts the breath instrument reading, in some juridictions there may be a defence. In Canada this is called a Carter defence or "evidence to the contrary".
- Causes Bodily Harm: induce, make, be cause of, part and parcel, in order to enable, to continue or facilitate, injured as the result of an accident
- cell phone interference: There is considerable debate about this subject. Some breath instruments have radio frequency interference detectors that automatically shut down the test sequence and print an error card if RFI interference is detected. Some experts take the position that cell phone interference can cause elevated BAC readings on breath test instruments. They suggest that if a cell phone is transmitting (a call is in progress) and it is placed near the instrument there will be strange results. Other experts insist that this is not the case. There is a need for study of this issue.
Police radios and other radio transmitters are also alleged to impact on the accuracy of breath tests.
- certificate of analyst, certificate of analysis: The Standard Alcohol Solution (SAS) that is used as an external standard to run a calibration check of a breath instrument is contained in a simulator. Unless that SAS is reliable and accurate the external standard is useless. Prior to use, a batch of SAS is tested in a lab using a gas chromatograph to determine that it is a proper standard alcohol solution. The analyst who tests and approves the SAS as suitable for use will complete a certificate that he or she has analyzed a representative sample of the lot and certifies it in a document called a certificate of analysis.
- Certificate of Qualified Technician: Instead of calling viva voce evidence from a qualified breath tech who conducted a breath test using a breath instrument and having him or her prove that the machine was working properly, it may be appropriate for the breath tech to prepare a certificate that is filed in Court as a shortcut for the prosecutor.
This is different from the Certificate of Analysis of a standard alcohol solution.
- chemical tests: If you have been arrested for DUI, DWI, OUI, OWI or a related charge, you may be required to provide a sample of your blood, breath or urine for the purpose of testing your blood alcohol concentration. The concept of chemical tests includes blood, breath and urine. See the "implied consent" law that may apply in your state.
- Constitutional Validity of Legislation: Sometimes laws made by a parliament or a legislature may contradict the supreme law of a country, its constitution. A constitutional democratic government gets its authority and power to make law from its constitution. Laws made exceeding the jurisdiction given to that government without the authority of the constitution may be meaningless if a Court in that country makes that determination. When a law is unconstitutional the Courts may say that the law is meaningless or that it should be "read down" so as not to be beyond the jurisdiction of the government. Courts have a duty to construe and apply laws to specific fact situations. Sometime they have to construe a particular law as meaning nothing and sometimes they have to construe the law as meaning something different from the letter of the law passed by Parliament.
A law is ultra vires if it is beyond the jurisdiction of the legislature.
- conviction: There is a big difference between being investigated for a crime and being convicted of a crime. Just because an allegation has been made or a person has been arrested by police doesn't mean that they are guilty of a crime. In countries where there is a presumption of innocence, you aren't gulity until you've been proven guilty by a prosecutor after evidence has been submitted and accepted by a judge. People often are too quick to assume that a charge laid means that a conviction will automatically follow. A "conviction" refers to a formal finding by a judge that a person is guilty of the offence charged and that the judge has decided to enter a conviction.
- Counsel: barrister or group of barristers, lawyer or attorney, advocate. Interesting legal issues arise where an individual seeks legal advice from a friend or relative who is a police officer or wishes to retain a paralegal.
- Counsel of Choice: If an individual is arrested or detained they may have the right to consult with a lawyer or attorney. That right may be part of constitutional law, judge made law, or a particular statute. The right to the consultation may be long or short, in person or over the telephone, under the control of the police or in privacy, all depending on the jurisdiction and the context. The person charged may or may not have the right to choose a particular lawyer or attorney to consult. "Counsel of choice" refers to the right to consult with the particular lawyer or attorney that the detainee chooses, not simply one chosen by the police or supplied by the government.
- Coutts_Milne_Huff_White: Three important Canadian cases having to do with what evidentiary use can be made of statements, screening device tests, and physical tests obtained by police during the period prior to right to counsel. There may be a difference between evidence gathered for the purpose of reasonable and probable grounds for arrest and demand as opposed to proving guilt at trial.
- criminal negligence: When an individual has the mens rea (knowledge) that a crime has been, is or will be committed. This includes being willfully blind or careless.
- criminal procedure: Laws related to procedure in the criminal court system. Not substantive criminal law related to criminal offences or evidence law related to evidence rules at trial. Criminal procedure law governs such things as warrants, arrest, bail hearings, notices to parents for juveniles, preliminary inquiries, informations and indictments, Crown and defence elections, mode of trial, jury selection, jury trial procedure, procedure at trial, and sentencing procedure.
- D.U.I.: Driving Under the Inflence
- Demand: Before a police officer has the right to seize a sample of breath or blood there may be conditions precedent. In some jurisdictions, the seizure will not be lawful unless the police officer makes a formal Demand for such a sample upon reasonable grounds for such a formal Demand.
- demerit points: some jurisdictions attach a number of demerit points for a particular offence, licence is suspended or licensee is brought in for an interview after a number of points are accumulated
- designation: A Canadian accused can appoint counsel to represent the accused in any proceedings by filing a designation with the court.
- diabetic: DKA; Ketoacidosis; by-products of fat breakdown are ketones: fruity smell on breath, acetone, fasting, not eaten food all day. Persons who suffer from diabetes may be producing acetone on their breath. Acetone may mimic ethanol drinking-alcohol on breath instrument readings and cause inflated readings. Acetone detect and subtract circuits may not be adequate to detect or remove the acetone portion of the reading.
- Disclosure: The accused should be afforded the opportunity to see the case for the prosecution, the evidence that the State or Crown will use against him or her long before the trial begins. At the very least the defence should receive discovery of a copy of the prosecutor's brief of police officers' and witnesses' statements before plea.
- distinction between impaired driving and over 80: some jurisdictions have separate offences for operation of a motor vehicle while ability to do so impaired and the separate per se offence of having a blood alcohol concentration above 0, 50, 80, or 100 mgs/100mLs
- does car have to be running to be charged: What is meant by care or control of a motor vehicle?
Does the engine have to be running to be in care or control?
Do the keys have to be in the ignition to be guilty of impaired care or control?
In Canada a person can be in deemed care or control simply by sitting in the driver's seat. See the section 258(1)(a) presumption:
(a) where it is proved that the accused occupied the seat or position ordinarily occupied by a person who operates a motor vehicle, vessel or aircraft or any railway equipment or who assists in the operation of an aircraft or of railway equipment, the accused shall be deemed to have had the care or control of the vehicle, vessel, aircraft or railway equipment, as the case may be, unless the accused establishes that the accused did not occupy that seat or position for the purpose of setting the vehicle, vessel, aircraft or railway equipment in motion or assisting in the operation of the aircraft or railway equipment, as the case may be;
But this isn't the only kind of care or control. There is also care or control in fact where the accused has some sort of connection with the fittings on the car.
- double jeopardy: A defense in which an individual cannot be charged and tried twice based on the same set of facts and events.
- driving on opposite side of road: Does driving on the opposite side of the road constitute dangerous driving? Is driving on the opposite side of the road an indicia of impaired driving
- drug: A chemical substance that affects the function of living things. Drugs can be used to treat illness, or modify a chemical process in the body for a specific purpose. Drugs can also impair one's ability to operate a motor vehicle. Some drugs work together with alcohol to exacerbate impairment.
- duplicity: No synopsis available yet. Please add.
- elimination: Ethanol is absorbed in the mouth, the stomach, and the small intestine. Rate of absorption depends on many factors.
Ethanol is distributed throughout the body.
Ethanol is metabolized by the liver and eliminated at a rate of 10 to 20 mg/100Mls/hr.
- employee education: Your company will need to educate employees as to their unique blood alcohol concentration effects of each standard drink as well including both absorption and elimination. Employees need to learn how to carefully monitor and document their drinking prior to driving. A business may lose a valuable employee to detention, jail, injury, or embarrassment if its management does not take steps to educate employees about alcohol absorption, distribution, elimination and the effects of alcohol at different stages.
- Evidence to the Contrary: In some jurisdictions the evidence and presumptions of accuracy and identity of a breath instrument can be contradicted by evidence of the accused as to alcohol consumed and the expert evidence of a toxicologist. In Canada this is often called a Carter defence.
- Exclusion of Evidence Remedy 24(2): In Canada, if police or the Crown violate rights under the Canadian Charter of Rights and Freedoms, the Court may make an order excluding evidence of confessions, breath tests or other evidence that would otherwise be admissible. This is the Canadian equivalent of "suppression".
- exemption for employment purposes: In some jurisdictions it may be possible to have an exception to a licence suspension to permit driving for employment purposes only. Other jurisdictions prohibit all driving during suspension. See also licence
- expert affidavits: A sworn statement of fact acknowledged by an expert in their field. A taker of oaths such as a notary public must witness the affidavit.
- failure to stop: This occurs when an individual is involved in an driving related accident, and they fail to stop to exchange information or to check if other were harmed.
- Fifteen Minutes Apart: There is some evidentiary advantage to obtaining two breath analysis results obtained from two different samples separated in time. If the results are in good agreement (eg. within 20 mg/100 mLs of each other truncated) then it is safer to assume that the breath sampling procedure followed has not resulted in an erroneous result caused by, for example, the presence of mouth alcohol. In Canada the protocol is at least 15 minutes apart but other protocols are used elsewhere.
- first offence: On your first offence of impaired driving, driving with a blood alcohol content over 80, or refusing to give a breath or blood sample there may be minimum penalties. The minimum penalties that a judge must impose in Canada for a first offence would be a fine of at least $1000 and prohibition from driving anywhere in Canada for at least one year. The existence of a pardon or suspension of conviction may cause a second or third offence to be treated as a first in Canada. A second offence which occurred at a point in time before the actual conviction for the first may also be treated in Canada as a first offence for Criminal Code purposes.
- Forthwith: A term found which can be found in contracts, court orders, and statutes, which means as soon as it can be reasonably done. It also implies immediacy, with no excuses for delay. Breath test demands in Canada must be made forthwith or as soon as practicable.
- Gas chromatography: a method to check the concentration of a sample of standard alcohol solution (SAS)
- headspace: headspace: the vapour portion above the liquid in a simulator containing standard alcohol solution (SAS) if the headspace has not yet warmed up to the same temperature as the liquid in the simulator, low caliberation checks may result.
- How do I plead guilty in Ontario if I live in another Alberta?: Usually you need to physically appear in the Canadian courthouse in the city and province where the criminal offence happened. If you immediately retain a lawyer in that jurisdiction you can sign a document called a Designation whereby that lawyer can attend on most Court days instead of you. On the final day when you are ready to plead guilty and after all negotiations are complete you will need to physically attend at the courthouse before the Judge to receive your punishment.
- how long between dwi charges does your loss of licence increase: In most jurisdictions there is a statutory or regulatory protocol for looking back at previous convictions. In Ontario for Highway Traffic Act purposes it is 10 clear years. In Ontario for Criminal Code purposes it is theoretically forever but Crowns usually look back 5 to 10 years from a 2nd offence or forever from a 3rd.
- Ignition interlock: a driver of a vehicle equipped with this device will not be able to start the car or continue to drive it if he or she does not blow into the machine, a failure may result in lights flashing and horn blowing.
- Impaired: There is a difference between a person being "impaired" by alcohol and a persons's "ability to operate a motor vehicle" being impaired by alcohol. In Canada see the R. v. Stellato case for a definition of "impairment".
- impound vehicle: Some jurisdictions permit the police to seize the vehicle used in the DUI or the drive while suspended offence. The vehicle may be towed to a police or private pound and held pending further investigation or payment of a fee. Some jurisdictions allow the police to hold the vehicle for a certain number of days.
- Included Offences: A person tried for an offence such as break, enter, and theft may be found not guilty of the offence charged of break, enter and theft but guilty of the lesser and included offence of theft. In Canada, Crowns frequently take the position that impaired care or control of a motor vehicle is an included offence to the charge of impaired driving. In other words, if the person cannot be proven to be driving they can still be convicted of care or control. This is not the case in some other jurisdictions.
- indicia of impairment: Reasonable grounds to suspect that an individual is impaired (i.e. smell of alcohol).
- Information Component Right to Counsel: Right to Counsel. Police in Canada are obliged to comply with both the informational component of the Charter section 10b right to counsel as well as provide the opportunity to retain and instruct counsel without delay. The informational component includes the obligation under R. v. Brydges to tell the detainee about the existence of and how to access 24 hour emergency duty counsel.
- instrument: a tool,a machine used to accomplish something, a breath instrument
Some people get very upset when you call a breath instrument a "machine". In the field of forensic breath testing the term implies precision, accuracy, and following protocol.
- insurance implications: A DUI allegation or conviction may be very costly for many years with a very large surcharge imposed by your insurance company. Insurance companies may also raise rates as a result of administrative licence suspensions, accidents, and plea bargains to lesser offences such as careless driving.
- Intent - Mens Rea: Mens Rea refers to the mental state (guilty mind) that must be an adjunct to a prohibited act before it can be considered a crime. Different type of offences require different mental states. For example, was there intention to commit theft or was there some knowledge that the property possessed is stolen. Generally an essential ingredient to every criminal offence, but not necessarily applicable to minor provincial offences. A guilty act requires a guilty mind: Actus non facit reum, nisi mens sit rea
- interferent: Also known as "interferent bias"
Evidentiary breath instruments are designed to alert the qualified technician if an interferent, such as acetone, is detected on the breath of the test subject. The ethanol molecule's IR signature has similarities at certain wavelengths to acetone, methanol, and isopropanol. This means that if a breath instrument is not designed to alert the qualified technician as to the presence of an interferent, then acetone, methanol, isopropanol (if present on the breath or in the room) could falsely elevate the breath readings. Evaluation of evidentiary breath instruments requires that particular substances that are produced endogenously and could be present in human breath, be tested to determine if they could create such an interferent bias.
Non-evidentiary screening devices usually do not contain the hardware or software necessay to alert for or subtract for other alcohols such as isopropanol. The presence of a substance such as isopropanol can damage a fuel cell sensor.

Isopropanol Interference with Breath Alcohol Analysis: A Case Report
- internal standards: Internal standards within the breath testing instrument are different from an external standard alcohol solution in a separate simulator instrument. If a diagnostic test of the breath instrument using an internal standard indicates a fail the instrument is supposed to shut down automatically and indicate an error message.
- Interpreter During Right to Counsel: In English Canada a person, whose first language is not English, has the right to an interpreter during the informational component of their right to counsel and in actually making use of that right. In practice the 24 hour duty counsel system in Canada makes extensive use of interpreters speaking many many languages. The same rule should apply to persons who are hearing impaired. The same rule applies in French Canada. There is a big difference between a police officer interpreter who understands rudimentary sign language and a proper interpreter.
- intoxicated drivers: Intoxication is being drunk, being excited or elated beyond self-control by an intoxicating substance, such as ethanol.
What proportion of drivers are intoxicated during the day?
What proportion of drivers are intoxicated during the evening?
What proportion of drivers are intoxicated in the early morning hours?
- Intoxication During Right to Counsel: Is it a defence to a per se over 80 offence to say that you were too drunk to understand your right to counsel and so you couldn't understand the informational component of your right to counsel, which means you didn't waive your right to counsel prior to the breath tests, which means you weren't properly afforded your right to counsel and therefore the taking of breath tests by police is illegal - all because you were too drunk? Needless to say Courts don't particularly like this argument in drunk driving cases.
- IR: Infrared Spectrometry, measure blood alcohol concentration by analyzing a breath sample in a chamber through which IR light is passed. Different molecules (eg. ethanol) absorb IR light to different extents at different wavelengths. By measuring how much IR light is absorbed at a wavelength relevant to ethanol one can determine the concentration of ethanol in the sample compared to no ethanol. However, any other substance that absorbs IR at the same frequency will mess up that calculation - we call those interferents. The best breath machines are ones that are specific (specificity) to ethanol.
- isopropanol: rubbing alcohol, an interferent that sometimes looks to an IR breath instrument just like ethanol. Used by and inhaled by people in the printing industry. Hopefully the breath test instrument will flag the isopropanol contaminated breath test with an error message. However, combinations of ethanol and isopropanol are more difficult to detect.
- jury: A group of lay ordinary persons who try issues of fact. The answer to the question of whether a trial will be by judge alone or judge and jury depends on whether or not a jury trial is available according to the law in the particular state or province.
If a jury trial is available, one needs to consider the functions of the judge and the jury. Generally the judge makes determinations of law and the jury makes determinations of fact.
- juvenile convictions: What impact do juvenile convictions or youth court findings of guilt have on sentencing for an adult offence? Do minimum sentences apply?
- keys in the ignition: See also care or control. If a drinking driver has stopped driving, parked the car, and gone to sleep behind the wheel is he or she still "drinking and drivin". Different jurisdictions deal with this problem in different ways. On the other hand some people use a motor vehicle or a motorhome as a house. Can you be convicted if you enter or decide to use the motor vehicle as a house rather than as a vehicle? It depends on your jurisdiction. Speak to a lawyer in your own community. Keys in the ignition msay or may not be one of the indicia that you intended to operate the vehicle in which you were sleeping.
- last chance: How many times should a person get to try to blow into a breath machine? Should there be a warning before a refusal charge is laid?
- last drink defence: Also known as rising alcohol defence or bolus drinking defence. If absorption is still greater than elimination because alcohol consumption was recent and perhaps bolus, then BAC at time of driving may be less than that at time of breath test at police station.
- licence for work: Is there any way I can keep my driver's licence if I am convicted of DUI? Some jurisdictions have automaqtic licence suspensions that operate upon conviction and are beyond the control of the Judge or the prosecutor. Some jurisdictions have minimum punishments such that a Judge has no option but to impose the mandatory minimum prohibition order.
- limitation period: The maximum length of time after an offence during which a criminal charge can be laid. A period of time specified in a statute within which a criminal proceeding must be commenced. A statute of limitations.
- measurement: VIM 2012
2.1 (2.1) measurement
process of experimentally obtaining one or more quantity values that can reasonably be attributed to a quantity
NOTE1 Measurement does not apply to nominal properties.
NOTE 2 Measurement implies comparison of quantities or counting of entities.
NOTE 3 Measurement presupposes a description of the quantity commensurate with the intended use of a measurement result, a measurement procedure, and a calibrated measuring system operating according to the specified measurement procedure, including the measurement conditions.
2.1 (2.1) mesurage, m mesure, f
processus consistant à obtenir expérimentalement une ou plusieurs valeurs que l'on peut raisonnable- ment attribuer à une grandeur
NOTE 1 Les mesurages ne s'appliquent pas aux pro- priétés qualitatives.
NOTE2 Un mesurage implique la comparaison de grandeurs ou le comptage d'entités.
NOTE 3 Un mesurage suppose une description de la grandeur compatible avec l'usage prévu d'un résultat de mesure, une procédure de mesure et un système de mesure étalonné fonctionnant selon la procédure de mesure spécifiée, incluant les conditions de mesure.
- measurement standard: VIM 2012
5.1 (6.1) measurement standard etalon
realization of the definition of a given quantity, with stated quantity value and associated measure- ment uncertainty, used as a reference
EXAMPLE 1 1 kg mass measurement standard with an associated standard measurement uncertainty of 3 μg.
EXAMPLE 2 100 measurement standard resistor with an associated standard measurement uncertainty of 1 μ.
EXAMPLE 3 Caesium frequency standard with a relative standard measurement uncertainty of 2 10–15.
EXAMPLE 4 Standard buffer solution with a pH of 7.072 with an associated standard measurement uncertainty of 0.006.
EXAMPLE 5 Set of reference solutions of cortisol in human serum having a certified quantity value with measurement uncertainty for each solution.
EXAMPLE 6 Reference material providing quantity values with measurement uncertainties for the mass concentration of each of ten different proteins.
NOTE1 A “realization of the definition of a given quantity” can be provided by a measuring system, a material measure, or a reference material.
NOTE 2 A measurement standard is frequently used as a reference in establishing measured quantity values and associated measurement uncertainties for other quantities of the same kind, thereby establishing metrological traceability through calibration of other measurement standards, measuring instruments, or measuring systems.
NOTE 3 The term “realization” is used here in the most general meaning. It denotes three procedures of “realization”. The first one consists in the physical realization of the measurement unit from its definition and is realization sensu stricto. The second, termed “reproduction”, consists not in realizing the measurement unit from its definition but in setting up a highly reproducible measurement standard based on a physical phenomenon, as it happens, e.g. in case of use of frequency-stabilized lasers to establish a measurement standard for the metre, of the Josephson effect for the volt or of the quantum Hall effect for the ohm. The third procedure consists in adopting a material measure as a measurement standard. It occurs in the case of the meas- urement standard of 1 kg.
NOTE 4 A standard measurement uncertainty associated with a measurement standard is always a component of the combined standard measurement uncertainty (see GUM:1995, 2.3.4) in a measurement result obtained using the measurement standard.
Frequently, this component is small compared with other components of the combined standard measurement uncertainty.
NOTE 5 Quantity value and measurement uncertainty must be determined at the time when the measurement standard is used.
NOTE6 Several quantities of the same kind or of different kinds may be realized in one device which is commonly also called a measurement standard.
NOTE 7 The word “embodiment” is sometimes used in the English language instead of “realization”.
NOTE 8 In science and technology, the English word “standard” is used with at least two different meanings: as a specification, technical recommendation, or similar normative document (in French “norme”) and as a meas- urement standard (in French “étalon”). This Vocabulary is concerned solely with the second meaning.
NOTE 9 The term “measurement standard” is some- times used to denote other metrological tools, e.g. ‘software measurement standard’ (see ISO 5436-2).
réalisation de la définition d'une grandeur donnée, avec une valeur déterminée et une incertitude de mesure associée, utilisée comme référence
EXEMPLE 1 Étalon de masse de 1 kg avec une incer- titude-type associée de 3 μg.
EXEMPLE2 Résistance étalon de 100 avec une incertitude-type associée de 1 μ.
EXEMPLE 3 Étalon de fréquence à césium avec une incertitude-type associée de 2 10–15.
EXEMPLE 4 Solution tampon de référence ayant un pH de 7,072 avec une incertitude-type associée de 0,006.
EXEMPLE 5 Série de solutions de référence de cor- tisol dans du sérum humain, dont chaque solution a une valeur certifiée avec une incertitude de mesure.
EXEMPLE 6 Matériau de référence fournissant des valeurs avec les incertitudes de mesure associées pour la concentration en masse de dix protéines différentes.
NOTE 1 La «réalisation de la définition d'une grandeur donnée» peut être fournie par un système de mesure, une mesure matérialisée ou un matériau de référence.
NOTE2 Un étalon sert souvent de référence dans l'obtention de valeurs mesurées et d'incertitudes de mesure associées pour d'autres grandeurs de même nature, établissant ainsi une traçabilité métrologique par l'intermédiaire de l'étalonnage d'autres étalons, ins- truments de mesure ou systèmes de mesure.
NOTE 3 Le terme «réalisation» est employé ici dans son sens le plus général. Il désigne trois procédures de réalisation. La première, la réalisation stricto sensu, est la réalisation physique de l'unité de mesure à partir de sa définition. La deuxième, appelée «reproduction», consiste, non pas à réaliser l'unité à partir de sa définition, mais à construire un étalon hautement reproductible fondé sur un phénomène physique, par exemple l'emploi de lasers stabilisés en fréquence pour construire un étalon du mètre, l'emploi de l'effet Josephson pour le volt ou de l'effet Hall quantique pour l'ohm. La troisième procédure consiste à adopter une mesure matérialisée comme étalon. C'est le cas de l'étalon de 1 kg.
NOTE4 L'incertitude-type associée à un étalon est toujours une composante de l'incertitude-type com- posée (voir le GUM:1995, 2.3.4) dans un résultat de mesure obtenu en utilisant l'étalon. Cette composante est souvent petite par rapport à d'autres composantes de l'incertitude-type composée.
NOTE 5 La valeur de la grandeur et l'incertitude de mesure doivent être déterminées au moment où l'étalon est utilisé.
- measuring interval: VIM 2012
4.7 (5.4) measuring interval working interval
set of values of quantities of the same kind that can be measured by a given measuring in- strument or measuring system with specified instrumental measurement uncertainty, under defined conditions
NOTE 1 In some fields, the term is “measuring range” or “measurement range”.
NOTE 2 The lower limit of a measuring interval should not be confused with detection limit.
intervalle de mesure, m
ensemble des valeurs de grandeurs d'une même nature qu'un instrument de mesure ou un système de mesure donné peut mesurer avec une incertitude instrumentale spécifiée, dans des con- ditions déterminées
NOTE 1 Dans certains domaines, le terme anglais est «measuring range» ou «measurement range». En fran- çais, le terme «étendue de mesure» est parfois impropre- ment employé.
NOTE2 Il convient de ne pas confondre la limite inférieure d'un intervalle de mesure avec la limite de détection.
- mens rea: Intent in criminal law. As a general rule, you can't be guilty of a criminal offence if you inadvertently did something against the law. Crimes require a deliberate act or recklessness. There are lots of exceptions to this general rule.
- mmol: 1 millimole equals 4.6 mg/100mls or .0046
- Motor Vehicle: A self-propelled wheeled conveyance, such as a car or truck, that does not travel on rails
- mouth alcohol: Also known as "mouth alcohol bias"
Ethanol remaining in the mouth following a recent drink (last 15 minutes) or as the result of vomitting, GERD, burping, mouthwash may exaggerate breath test readings dramatically. Evidentiary breath instruments are usually designed so as to alert the qualified technician that mouth alcohol or stomach alcohol has been detected rather than deep lung air alcohol. This is accomplished through a slope detection algorithm in the software which looks for a peak in the readings coming in near the beginning of the breath sample with a rapid drop off followed by a combined effect of deep lung air alcohol and the mouth. The instrument shuts down and prints a warning often stated as "Invalid Sample".
Unfortunately, although the software usually does what it is supposed to do (i.e. watch for the peak and report), mouth alcohol bias can still occur due to the combined analysis of a small amount of mouth alcohol combined with a fairly low true blood alcohol concentration. It is very possible for an individual with a true BAC of 30 mg/100mLs to blow a 120 mg/100mLs reading and for a person with a true BAC of 115 mg/100mLs to blow over 300 mg/100mLs. A person whose true BAC is just under the legal limit (eg. 78 mg/100mLs) could blow just over the legal limit (eg. 87 mg/100mLs).
In some jurisdictions there is a requirement for two tests. If those tests are well spread out in time (eg. 15 minutes apart) and the two tests are in good agreement with each other (eg. within 20 mg/100mls of each other truncated) then mouth alcohol bias is less likely.
Another best practice to reduce the possibility of mouth alcohol bias is a deprivation period (observation period) of 15 to 20 minutes before the breath tests wherein the qualified technician keeps the subject under continuous observation for that period to ensure that he or she does not vommit, consume alcohol, gum or breath strips, belch or burp.
Non-evidentiary breath instruments used as screening devices generally do not have mouth alcohol slope detectors.
- mouth alcohol delay: See Bernshaw in Canada. A police officer should not immediately administer a roadside screening device test if he or she has information that there may be a source of mouth alcohol (eg. a very recent drink of alcohol, recent mouthwash, vomit), rather the screening device test should be delayed about 15 or 20 minutes to make sure that there is no alcohol in the mouth that would cause mouth alcohol bias.
- Necessity: In evidence law, "necessity" is sometimes used as one of the criteria to make a principled determination of an exception to the hearsay rule.
In criminal law, "necessity" is sometimes argued as a defence to a criminal offence. A person who has a sick child, for example, MAY be justified in exceeding the speed limit on the way to the hospital. An unsuccessful example of this argument can be found in R. v. Tjeltveit, 1994 CanLII 5078 (SK Q.B.):
"In essence his argument is that as he was not in the
driver's seat the basis upon which he was found to be in care
and control was the fact of his having the motor running and
the heater on. As the reason for having the heater on was the
cold weather condition which prevented his leaving the
vehicle, it was thus a necessity and, therefore, he ought not
to have been convicted."
- no contest: No contest means that the defendant neither admits nor disputes the charge. A plea without actually admitting guilt.
- Notice re Certificate of Analysis: If the prosecutor proceeds by certificate evidence rather than viva voce evidence of the analysis, should the accused have advance notice?
- O.W.I.: Operating while intoxicated.
- observation period: Mouth alcohol distorts breath readings. The officer should observe you for awhile to make sure you don't consume more alcohol or belch so that alcohol ends up in your mouth.
- onus of proof: The onus of proof represents the responsibility of the crown or defense to prove either the innocence or guilt of the accused. In Canadian Criminal law, the onus is on the Crown Attorney to prove the guilt of the accused.
- Operating or Driving: In most jurisdictions it is a criminal offence to drive or operate a motor vehicle while intoxicated. If the motor vehicle is not moving is it being driven or operated? Is it in gear, are the lights on, is it on the road? What if you are sleeping? Where is your head? Where are your feet? Are you in the driver's seat. Different jurisdictions deal with these issues in different way. Some people live in cars. If you live in a car and you sleep in the driver's seat are you operating it? See also care or control.
- pardon: A period of time after your conviction you may be able to apply for a pardon. A pardon granted by a government authority takes away some but not all of the legal consequences of a criminal conviction. In Canada we don't have pardons any more. You may be able to get a Suspension of Conviction after a period of time, but it is not as good as a pardon.
- pas: passive alcohol sensor. Hand held battery operated, flashligh, held close to driver's breath, no blowing neccessary
- penalties: Sentences and sentencing law varies from jurisdiction to jurisdiction.
- Physical Tests: These tests are designed to assess your physical and mental alertness. An officer
may require you to perform a series of tests if he/she suspects you to be intoxicated while operationing a motor vehicle.
Some of the test may include: Walking a straight line, walking frontwards or backwards,
Standing on one leg etc.
- police report: synopsis of events prepared by the investigating officer and included in the prosecutor's brief
- privacy: Separate the concepts:
1. An individual's right to privacy.
2. Privacy during consultation with counsel.
- Privacy During Right to Counsel: An individual who is consulting with a lawyer prior to interrogation or in preparation for Court should be afforded the right to speak to that lawyer in private.
- private: No synopsis available yet. Please add.
- prohibition: Separate the concepts:
1. prohibition order by a judge respecting driving or operating (which is different from suspension of a driver's licence)
2. the equitable remedy of prohibition - a superior court prohibits an inferior court or tribunal from exceeding its jurisdiction
- public documents: Information in the public domain i.e reported decision, press statements, etc. Documents made public have minimal security which allows for them to be approved for public use.
- R.I.D.E.: Reduce Impaired Driving in Etobicoke. Reduce Impaired Driving Everywhere. Roadside (sometimes holiday) spot checks looking for drunk drivers.
- random stop: Do police officers have the right to randomly stop you without giving you a justifed reason for the stop?
- Reasonable and Probable Grounds: A police officer must have reasonable and probable grounds prior to searching an individual. Therefore, an officer must suspect that an individual has committed a crime before they search them.
- Reasonable Excuse: Without reasonable excuse, fails or reuses to provide. See section 254
- reasonably suspects: See section 254 in Canada re a police officer's power to demand a roadside screening sample of breath.
- reciprocal agreements: Many states and provinces have agreements with other states and provinces that cause driver's licence suspensions for a driver in his or her home state or province as the result of a conviction for an offence in another state or province.
- refuses: No synopsis available yet. Please add.
- repudiation of resolution agreement: If the prosecutor and defence reach an agreement respecting resolution of a criminal charge should it be open to the prosecutor to renege or repudiate that agreement if a later prosecutor thinks it is a bad deal, contrary to policy, or not in the public interest. Should the Crown be able to unilaterally end a plea agreement?
- retain: hire a lawyer, obtain the services of an attorney, engage
- right: something you own or have that the state can't ignore, protected by the law, you can give it up but probably shouldn't, police must respect it and allow for it, you should assert it, it belongs to a person because they are a person, other persons or the state need to respect it, it arises because of a law or a constitution or because you are a person
- Right to Counsel: right to have a lawyer's advice before doing something particularly respecting a court case
- Right to Silence: legal protection given to people undergoing police interrogation during questioning. In some countries the right to silence can also be applied to trial proceedings.
- rising alcohol: The time of driving is always different from the time when the breath, blood, or urine test is taken.
Blood Alcohol Concentration is almost always different at the time of driving than it is at the time the evidentiary tests are undertaken.
During the elimination phase BAC is dropping over time because the body is eliminating alcohol at a rate between 10 mg/100mLs/hr and 20 mg/100mLs/hr. Therefore usually it is safe to assume that the BAC at time of tests by the police is lower than at the time of driving.
However, if alcohol was consumed very shortly before driving, depending on the type of alcohol, the stomach, and food, absorption of all the alcohol may be delayed (the absorption phase) and then BAC rises AFTER the driving resulting in inflated results in the police tests if the police tests are taken later in the absorption phase, during the plateau phase, or at the beginning of the elimination phase.
- sampling breath: Sampling breath provides a rapid determination of alcohol concentration in breath
- Search or Seizure: When a police officer (or agent of the police) searches an individual's belongings and confiscates property.
- simulator: A scientific instrument which holds a standard alcohol solution and maintains that solution at a constant temperature similar to that of human breath 34.0 +-.2 degrees C. When air is bubbled through the standard alcohol solution and pushed into a breath test instrument the standard alcohol solution can be used to calibrate or check the calibration of the breath test instrument. Depending on the SAS used the simulator can be used to simulate a human being's breath who has a 50, 100, 150, 200, or 300 mg/100mLs blood alcohol concentration.
- slight impairment: Please be sure to differentiate impairment of ability to operate a motor vehicle.
- smell of alcohol: Some people believe that pure alcohol has no odour. Others believe that their noses can detect pure alcohol. Sometimes an officer will detect the odour of an alcoholic beverage and may label that odour as strong. Sometimes an officer will label the odour as that of a particular alcoholic beverage.
Strong odour does not necessarily indicate elevated blood alcohol concentration.
- sobriety: No synopsis available yet. Please add.
- sobriety tests: Sometimes police officers ask persons they suspect of drunk driving to place their finger to their nose, recite the alphabet, or walk a straight line. Different jurisdictions have different laws about whether or not you have to do these and whether or not they are admissible in evidence at trial.
- Subsequent Conviction: For some purposes and in some jurisdictions a conviction is considered subsequent to a previous offence only if the individual has been convicted of the first offence before the date of occurrence of the second offence. For other purposes or in other jurisdictions it is only the sequence of convictions or only the sequence of offence dates that is considered. You will need to consult a lawyer or attorney in your jurisdiction to obtain an opinion.
- Suitable Sample: Breath samples vary depending on the portion of the lungs from which they are obtained. It may be up to the breath technician to determine whether or not a suitable sample has been received. That suitability may be the same or different from the suitability determined by the breath instrument itself.
- suspension starts: Some jurisdictions have administrative driver's licence suspensions that start immediately on arrest.
Some jurisdictions have automatic licence suspensions that commence upon conviction.
Some jurisdictions give judges a power to prohibit driving for a period of time.
Some jurisdictions have all of the above.
- technician: No synopsis available yet. Please add.
- Ten dui charges: Do Multiple DUI charges result in prison? The maximum penalty in Canada is 5 years if the offence is prosecuted by Indictment. If prosecuted by summary conviction the maximum punishment is 18 months. If bodily harm is caused the maximum is 10 years. If death is caused the maximum is life imprisonment.
- Two Tests: Any blood alcohol concentration analysis by means of a breath sample can be significantly affected by the presence of mouth alcohol. One method to reduce the possibility of this sort of error is to perform two tests. The two tests are separate breath samples taken several minutes apart. The results of analysis of these two samples are compared to see if they are in good agreement. If the samples are within 20 mg/100mLs they are considered to be in good agreement.
- underage: Drinking age varies by jurisdiction.
- Unreasonable Delay: Every individual has a right to proceed with their legal matter within a reasonable amount of time. If there is a delay in proceedings an individual can argue that there has been an unreasonable delay.
- vehicle: Automobile is a conveyance that transports people or objects.
- vessel: A boat, ship. Does it need a motor? Can an individual be convicted of intoxicated operation of a canoe or a sailboat? all things that float except small rowboats and sailboats?
- Waiver : Give up the right, refuse an offer, eg. from the police to permit communication with a lawyer. Don't sign anything entitled "Waiver" without proper legal advice.
Waiver of right to counsel, giving up one's right to a lawyer before interrogation or at Court
Waiver of juvenile matter into adult court, transferring a juvenile matter into adult Court.
- youth: Young persons, youth, or juveniles are defined differently in different jurisdictions. Most jurisdictions have special laws, procedures, and rights for the benefit of young persons having to do with their special needs. Some jurisdictions employ a child protection model (Canada's old Juvenile Delinquents Act) to youth justice and others apply a criminal justice model (Canada's Young Offenders Act and Youth Criminal Justice Act).
- zero tolerance: Zero tolerance connotes community condemnation of particular behaviour. Zero tolerance policies sometimes lead to presumption of guilt. Politicians, schools, and Courts need to be wary of zero tolerance policies if guilt is presumed or other Constitutional guarantees of rights are not protected. "Zero tolerance" is sometimes used in the context of driving under the influence of alcohol since drinking and driving is a major cause of death, injury, and damage in our communities. No matter how appropriate a "zero tolerance" policy may be from the perspective of politics, it is essential that a person suspected, accused, or charged with drinking and driving be afforded due process.
