Interlock Program

The Queensland Government introduced the Interlock Program for convicted drink drivers in 2011.  Currently there are proposed changes before parliament to the program. The changes include expanding the interlock program to drivers convicted of a mid range drink driving offence.  The Bill is on the next Parliament agenda for 20 August 2019.  

This page will be updated with the changes once made by the Queensland Government.

What is the interlock program?

The Interlock Program requires an alcohol ignition interlock device to be installed in your motor vehicle.  The alcohol ignition interlock device enables the vehicle to start upon receiving an alcohol free sample of breath.  If a BAC is detected, the vehicle will not start.  The vehicle cannot start unless a sample of breath is provided.

The aim of the program is to prevent re-offending for people convicted of drink driving offences.  It applies to people eligible for a licence after being convicted of nominated drink driving offences.  

To complete the program, you must have an approved interlock fitted to a vehicle for at least 12 months.  If you do not participate in the program and don’t have an exemption, you cannot drive for 2 years following the end of your disqualification period.  Driving during this period will result in further charges and disqualification period.

What offences result in the Alcohol Ignition Interlock Program?

Following conviction of any of the following offences, you will be subject to the Interlock Program:-

  • Dangerous driving while affected by alcohol.
  • Fail to provide a blood/breath sample.
  • Driving under the influence of alcohol.
  • A drink driving offence where the BAC was over 0.15.
  • Two or more drink driving offences within a 5 year period.

What is the process for taking part?

After your disqualification period ends, you need to make an application for your drivers licence to be issued.  You will then receive a probationary licence with an “I” condition.

An approved interlock device needs to be installed in your nominated vehicle.  There are two Queensland approved providers of interlock devices.  These are Guardian Interlock Systems and Draeger Australia Pty Ltd.  Discounts may apply if you have a health care card.  Alternatively,  financial assistance is available for low income applicants and families.

Your employer’s consent is required for a device to be installed in a company car.  You can only drive the nominated vehicle during the program period.

In limited circumstances, you can be exempt from the program.  To receive an exemption, you can apply six weeks before your disqualification ends.  When your exemption is approved, you are required to have the approved exemption certificate on you when driving.

More information is available at the Department of Transport and Main Roads.
