Understanding the Alcohol Interlock Program in Queensland
If you’ve been convicted of a drink driving offence in Queensland, you may be required to join the Alcohol Ignition Interlock Program before getting back behind the wheel.
An alcohol interlock is a breath-testing device connected to your vehicle’s ignition system. It prevents your car from starting if any alcohol is detected in your breath sample. This system helps improve road safety and reduce repeat drink driving offences.
Who Needs an Alcohol Interlock in Queensland?
You may need to have an interlock device installed if you:
Are convicted of a high-range drink driving offence (BAC 0.15 or higher)
Have been caught drink driving more than once
Refused to provide a breath or blood sample when required
You can view the full eligibility requirements on the Queensland Department of Transport and Main Roads (TMR) website.
How Does an Alcohol Interlock Work?
Once installed in your vehicle, the alcohol interlock works as follows:
You must blow into the device each time before starting your vehicle
If alcohol is detected, the vehicle won’t start
Random breath tests may be required while driving
All test data is recorded and sent to TMR to ensure compliance
The interlock must remain installed for at least 12 months. Failing to follow the rules can result in extended interlock periods, licence disqualification, or additional penalties.
