Impaired driving is one of the most common factors contributing to serious motor vehicle crashes in Canada. From 2000 to 2014, over 12,000 people are estimated to have died in crashes involving an alcohol-impaired driver. Drug-impaired driving is also a concern. According to a cannabis use and driving report, from 2000 to 2010, 16.6% of fatally injured drivers in Canada tested positive for cannabis. To help address impaired driving, CCSA conducts research, develops tools and resources, and produces materials to support evidence-based decisions and public policy.

Drug-Impaired Driving
Drug-impaired driving is underreported in Canada, making it difficult to address effectively. To improve measurement, CCSA gathered expert recommendations and formed an advisory committee that developed 34 standardized indicators across medical, legal, transportation and public surveys to enhance data collection, reduce fatalities and support policy making.
Heading
Research
Driving under the influence of alcohol or drugs is a leading cause of fatal motor vehicle crashes in Canada, with youth being the most affected group. Research explores the impact of alcohol, cannabis and other drugs on driving, highlighting concerns about cannabis-impaired driving among adults and the effects of certain prescription medications.
Heading
Resources
CCSA collaborates with partners to create evidence-based resources that raise public awareness about impaired driving, involving target audiences like youth in the design process. These resources include infographics, handouts and social media messages addressing alcohol, cannabis, prescription medications, and other drugs and driving.
Heading
Policy and Regulations
Impaired driving has severe personal and societal consequences, prompting laws and regulations at both federal and provincial levels. CCSA publishes briefs to explain these policies and the tools law enforcement use to address impaired driving.
What is Impaired Driving?
Impaired driving is operating any motorized vehicle (including cars, trucks, motorcycles, boats, airplanes, trains, jet skis and snowmobiles) while under the influence of alcohol, drugs or both. It is an offence under the Criminal Code in Canada and is an issue of public health and safety.
Preventing and Reducing Impaired Driving
Individuals can avoid impaired driving by using another form of transportation, such as public transit, a designated driver, ride sharing or a taxi, or by planning to spend the night. Individuals should also avoid riding with a driver who is under the influence of alcohol or drugs.
