The permitted blood alcohol concentration (BAC) for drivers operating a motor vehicle in Canada is strictly regulated. A BAC of 0.08% (80 milligrams of alcohol per 100 milliliters of blood) or higher constitutes a criminal offense nationwide. Provincial and territorial laws also address lower BAC levels, often resulting in administrative penalties such as license suspensions and vehicle impoundment.
Maintaining these regulations is crucial for road safety, aiming to reduce alcohol-related accidents and fatalities. Historically, increasing awareness and stricter enforcement have contributed to a decline in impaired driving incidents. The implementation of graduated licensing programs, further reinforces responsible alcohol consumption among novice drivers.
