The Ignition Interlock Device Program enhances public safety by giving eligible alcohol or drug offenders the option of having an ignition interlock device installed in their vehicle. 

Participating in the program ensures safe and legal driving, as well as allowing eligible alcohol or drug offenders to drive during the withdrawal period.

Ignition interlock device

An ignition interlock device is about the size of a hand-held calculator and includes a blowing tube. It's installed near the steering wheel and connected to the engine. 

The device prevents a vehicle from starting if it detects a certain alcohol concentration level after the driver blows into the tube.  

Required participants

You are required to enroll in the ignition interlock device program if your driving privileges are revoked for a:

• Second alcohol or drug offense in 10 years.

  OR 

• Third alcohol or drug offence on record, with one or two offenses more than 10 years old.  

Drivers identified as dangerous to public safety 

Your diving privileges can be canceled and denied if you are considered a danger to public safety. 

In this case, you're required to enroll in the program for a minimum of three to six years to regain full driving privileges. 

You may be considered dangerous to public safety if you have had three alcohol or drug offenses within 10 years, or four or more offences on record.

Optional participants

If you are a first-time alcohol offender who has had your license revoked, you have the option of regaining your driving privileges by participating in the program.
