Alcohol ignition interlocks

The Alcohol Ignition Interlock Program applies to drivers who are convicted of high-risk drink driving offences. The interlock program aims to help drink drivers separate drinking and driving when they get their licence back. If you don’t participate in the program you won't be able to drive for 2 years after your licence disqualification ends.

High-risk drink driving offences

You need to participate in the interlock program if you commit and are convicted of any of the following offences:

  • driving under the influence of alcohol
  • a drink driving offence with a blood/breath alcohol concentration of 0.15 or more
  • failing to provide a blood/breath specimen for analysis
  • dangerous driving while affected by alcohol
  • 2 or more drink driving offences within the 5 years.

You need to have an interlock device installed in the vehicle your drive during your time in the interlock program. Depending on your circumstances, you may be eligible for financial assistance to help with interlock costs.

You must meet strict eligibility criteria to apply for an interlock exemption.
