Impaired driving

Driving when your ability is impaired by alcohol or a drug is a crime in Canada. Your vehicle does not have to be moving; you can be charged if you are impaired behind the wheel, even if you have not started to drive.

In circumstances involving possible impairment by a drug or a combination of alcohol and a drug, police can require a driver to:

  • provide breath samples
  • perform standardized field sobriety tests
  • conduct a drug recognition evaluation
  • provide oral fluid, urine or blood samples for screening

If you fail or refuse to comply with any of these demands, you will be charged under the Criminal Code.

If you are 21 years of age and under, you must not drive if you have been drinking alcohol. Your blood- alcohol level must be zero.
