Drinking & Driving

Impaired Driving:

Driving when your ability is impaired by alcohol or drugs - is a crime.

Drinking and Driving:

Drinking and driving is a deadly combination. One drink can reduce your ability to:

  1. Concentrate on the driving task,
  2. Anticipate potentially dangerous situations while you are driving,
  3. React to them appropriately.

The more alcohol in your blood, the more trouble you have judging distances and reacting correctly to avoid a hazard. Your vision may also become blurred.

Drugs and Driving:

Any drug that changes your mood, or the way you see and feel, will affect the way you drive. The problem is not only associated with illegal drugs. There are prescription drugs and some over-the-counter drugs that can also impair your driving ability.


In Ontario, police have power to:

  • Stop drivers at random to determine whether to test for alcohol
  • Suspend your driver's licence at roadside for recording 0.05 blood alcohol concentration(BAC) or over on a breath test.

What is BAC?

Blood alcohol concentration, or BAC is the amount of alcohol in a person's body, measured by the amount of alcohol in blood. "0.05" means there are 50 milligrams of alcohol in every 100 millilitres of blood. BAC is used to define intoxication and provides a scientifically valid measure of the level of impairment.

Arrive Alive.

  • If you plan on drinking, plan not to drive:
  • Arrange a designated driver
  • Call a friend or relative
  • Take a taxi
  • Stay overnight
  • Take public transit

Ignition Interlock

  • The interlock system works by the person having to blow into the system, if it reads over the set limit the car will not start.
  • Once the car is started, it will require the driver to provide random breath samples at random times, if the breath sample is not given, unusual things will happen like the lights flashing, horn honking etc. until the vehicle is turned off.
  • When you refuse to have the breathalyser installed in your car if you get you driver's licence reinstated, you can not drive for at least one year.
  • First time offenders will have an ignition interlock system placed in their cars for at least one year.
  • Second time offenders will have the ignition interlock system placed on their licences for at least 3 years.
  • Third time offenders will have to deal with the ignition interlock system for life unless it's reinstated after 10 years.
  • The device is installed for the ignition interlock condition period. It must be used by anyone who drives the vehicle, including family and friends.
  • Fines can range from $200-$20,000 if you are caught tampering or driving without the system.
  • Who pays the cost of an ignition interlock device; drivers who are required to have an ignition interlock system are responsible for the installation costs and the maintenance costs.
