Drunk driving is the act of operating a motor vehicle with the operator's ability to do so impaired as a result of alcohol consumption, or with a blood alcohol level in excess of the legal limit. For drivers 21 years or older, driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal. For drivers under 21 years old, the legal limit is lower, with state limits ranging from 0.00 to 0.02. Lower BAC limits apply when operating boats, airplanes, or commercial vehicles. Among other names, the criminal offense of drunk driving may be called driving under the influence (DUI), driving while intoxicated or impaired (DWI), operating [a] vehicle under the influence of alcohol (OVI), or operating while impaired (OWI).
Peter Goldring is a former Canadian federal politician.
Driving under the influence (DUI) is the offense of driving, operating, or being in control of a vehicle while impaired by alcohol or other drugs, to a level that renders the driver incapable of operating a motor vehicle safely.
Mothers Against Drunk Driving (MADD) is a non-profit organization in the United States, Canada and Brazil that seeks to stop drunk driving, support those affected by drunk driving, prevent underage drinking, and strive for stricter impaired driving policy, whether that impairment is caused by alcohol or any other drug. The Irving, Texas–based organization was founded on September 5, 1980, in California by Candace Lightner after her 13-year-old daughter, Cari, was killed by a drunk driver. There is at least one MADD office in every state of the United States and at least one in each province of Canada. These offices offer victim services and many resources involving alcohol safety. MADD has claimed that drunk driving has been reduced by half since its founding.
The base rate fallacy, also called base rate neglect or base rate bias, is a type of fallacy. If presented with related base rate information and specific information, people tend to ignore the base rate in favor of the individuating information, rather than correctly integrating the two.
License suspension or revocation traditionally follows conviction for alcohol-impaired or drunk driving. However, under administrative license suspension (ALS) laws, sometimes called administrative license revocation or administrative per se, licenses are confiscated and automatically suspended independent of criminal proceedings whenever a driver either (1) refuses to submit to chemical testing, or (2) submits to testing with results indicating a blood alcohol content of 0.08% or higher.
A traffic stop, commonly referred to as being pulled over, is a temporary detention of a driver of a vehicle by police to investigate a possible crime or minor violation of law.
A breathalyzer or breathalyser is a device for estimating blood alcohol content (BAC), or to detect viruses or diseases or difference types of meat from a breath sample.
A Drug Recognition Expert (DRE) is a law enforcement officer trained to identify people whose driving is impaired by drugs other than, or in addition to, alcohol. All DREs follow the same 12 step procedure called a Drug Influence Evaluation (DIE), to determine which category of drugs is causing the driver to be impaired.
The terms "designated driver" and "designated driving" refer to the selection of a person who remains sober as the responsible driver of a vehicle whilst others have been allowed to drink alcoholic beverages.
R v Therens [1985] 1 S.C.R. 613 is an early Supreme Court of Canada decision on an accused's right to retain and instruct counsel without delay under section 10(b) of the Canadian Charter of Rights and Freedoms. The Court held that when a person was detained for the purpose of giving a breath sample under section 235(1) of the Criminal Code, they have the right to consult counsel. Since the police did not allow the accused to do so, they violated the accused's right to retain counsel. The Court ruled that the evidence was properly excluded.
A random checkpoint is a military and police tactic. In a military context, checkpoints involve the setup of a hasty roadblock by mobile truck- or armored vehicle-mounted infantry to disrupt unauthorized or unwanted movement or military activity and to check for valid identification and search for contraband, fugitives, or weapons that are not permitted in civilian hands. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could circumvent. They are often established in locations where they cannot be observed by approaching traffic until it is too late to withdraw and escape without being observed.
Michigan Dept. of State Police v. Sitz, 496 U.S. 444 (1990), was a United States Supreme Court case involving the constitutionality of police sobriety checkpoints. The Court held 6-3 that these checkpoints met the Fourth Amendment standard of "reasonable search and seizure."
Impaired driving is the term used in Canada to describe the criminal offence of operating, having care or the control of a motor vehicle while the person's ability to operate the motor vehicle is impaired by alcohol or a drug. Impaired driving is punishable under multiple offences in the Criminal Code, with greater penalties depending on the harm caused by the impaired driving. It can also result in various types of driver's licence suspensions.
The laws of driving under the influence vary between countries. One difference is the acceptable limit of blood alcohol content before a person is charged with a crime.
Drunk driving is the act of driving under the influence of alcohol. A small increase in the blood alcohol content increases the relative risk of a motor vehicle crash.
Drug–impaired driving, in the context of its legal definition, is the act of driving a motor vehicle while under the influence of an impairing substance. DUID, or Driving Under the Influence of Drugs, is prohibited in many countries. Several American states and European countries now have "per se" DUID laws that presume a driver is impaired if they are found to have any detectable quantity of controlled substances in their body while operating an automobile and that the driver has no doctor's prescription for the substance. This is similar to the "per se" DUI/DWI laws that presume a driver is impaired when their blood alcohol content is above a certain level. There is some controversy with "per se" DUID laws in that a driver with any detectable quantity of controlled substances may not in fact be impaired and the detectable quantity in blood or sweat may be only the remnants of drug use in days or weeks past. It is against road traffic safety.
Missouri v. McNeely, 569 U.S. 141 (2013), was a case decided by United States Supreme Court, on appeal from the Supreme Court of Missouri, regarding exceptions to the Fourth Amendment to the United States Constitution under exigent circumstances. The United States Supreme Court ruled that police must generally obtain a warrant before subjecting a drunken-driving suspect to a blood test, and that the natural metabolism of blood alcohol does not establish a per se exigency that would justify a blood draw without consent.
Field sobriety tests (FSTs), also referred to as standardized field sobriety tests (SFSTs), are a battery of tests used by police officers to determine if a person suspected of impaired driving is intoxicated with alcohol or other drugs. FSTs are primarily used in the US, to meet "probable cause for arrest" requirements, necessary to sustain an alcohol-impaired driving conviction based on a chemical blood alcohol test.
An Act to amend the Criminal Code and to make consequential amendments to other Acts, also known as Bill C-46, is an act of the Parliament of Canada that was introduced in the House of Commons by Minister of Justice Jody Wilson-Raybould in 2017, alongside the Cannabis Act. The act increases police powers related to impaired driving—including authorizing mandatory alcohol screening, without suspicion that the person is impaired—and it increases the maximum punishments for driving related offences in the Criminal Code.
