Alcohol ignition interlocks
Getting an interlock
About interlock devices
An interlock device is connected to a vehicle's ignition. To start the vehicle, the driver must provide a breath sample. The vehicle only starts if no alcohol is detected. A random breath sample may be requested during a journey.
The interlock records data including:
- all breath samples (including when the vehicle doesn't start)
- when the vehicle is used
- interlock service information.
Note: A vehicle with an interlock device installed can be driven by others, such as family members. Whoever is driving will need to provide breath samples to the interlock to start and continue driving the vehicle.
You need to install an interlock with a camera.
The camera will take a:
- reference photo when the interlock is first installed
- photo each time a breath sample is taken.
It is important that the camera can take a clear image of the person providing the breath sample to the interlock. If the camera is blocked or obscured in any way and the interlock detects alcohol, your time in the performance-based program can be extended.
WiFi-enabled interlocks may also be available if you participate in the performance-based program. If you have a WiFi-enabled interlock:
- your data will be sent to us when you are in WiFi range
- program notifications can be sent to you more quickly
- you won't need to get your interlock serviced at the end of the interlock program for us to receive your final data
Getting an interlock installed
You will need to complete steps 1, 2 and 3 before you can drive.
Step 1: Wait for your disqualification period to end
- You can apply for your licence the day after your disqualification ends (or the date you are granted a restricted (work) licence).
- You may also need to complete a drink driving short course.
Step 2: Apply to get your driver licence
You will need to apply for your licence with an interlock condition at a transport and motoring customer service centre, a participating QGAP office or licence-issuing police station (in rural or remote areas of Queensland).
You will need to:
- bring your evidence of identity
- if needed, bring a medical certificate stating you are fit to drive from your doctor
- pay the interlock condition fee plus the licence fee.
You will be issued with a receipt for a probationary licence with code 'I'. This will be your licence until you receive your physical card in the mail. If you have signed up to get emails we will email you when your licence is posted and send you a reminder when it's due to be renewed.
Your interlock must be installed before you drive.
Step 3: Get an interlock installed
After you get your licence you will need to have an interlock installed in the vehicle you want to drive. If you don’t own the vehicle but drive it, you must get permission from the owner to install the interlock.
Find an approved interlock provider and make an appointment to get your interlock installed. You will need to pay all installation costs. You can have an interlock on more than one vehicle if needed.
Vehicle nomination
At your appointment you will be asked to nominate which vehicle/s you want an interlock installed in. Your interlock provider will tell us which vehicle/s you nominate. You can only drive the vehicle/s you have nominated.
