The term "over 80" refers to operating a motor vehicle with a blood alcohol concentration (BAC) that exceeds the legal limit. In Canada, "over 80" refers to having a blood alcohol concentration of over 80 milligrams of alcohol per 100 millilitres of blood.
Driving with a BAC above the legal limit is considered a serious offence as it impairs one's ability to operate a vehicle safely. It poses risks not only to the driver but also to other road users. The legal limit of 80 milligrams of alcohol per 100 millilitres of blood is based on scientific research and is established to promote road safety.
Being charged with driving "over 80" can result in criminal penalties, including fines, potential imprisonment, license suspension, mandatory education or treatment programs, and other consequences determined by the court.
