Impaired Driving

When motorists follow safe driving practices, such as planning ahead and appointing a designated driver, the risks of death and injury, to themselves and others are reduced. The RCMP asks you to report impaired drivers on the road by pulling over and calling 911. Help prevent collisions and deaths that result from impaired driving.

Impaired driving investigations are technically complex and can involve drugs and/or alcohol. The RCMP and other police agencies across Canada conduct enforcement of drug impaired driving using Drug Recognition Experts (DRE). Learn more about the DRE program here.
