Pre-Interlock Removal Program

When Do You Complete the Pre-Interlock Removal Program? – If you are seeking to remove the Interlock condition from your licence you must do so in the last month of your Alcohol Interlock Program. You must obtain a copy of your performance record from the VicRoads Alcohol Interlock Management System.

The Pre-Interlock Removal Program is group based. The maximum number of participants in a group is 12. In this program you will revisit the action plan you completed from the behaviour change program before you were licensed with an alcohol interlock condition. You will discuss potential risks of drink-driving when the alcohol interlock device is removed and develop strategies to prevent drink-driving in the future.

The Interlock Program

An Interlock is a small, hand-held breath-testing device fitted to a vehicle’s ignition. They may be fitted to cars, motorcycles, trucks or buses. The driver must blow into the interlock before attempting to start the vehicle, and if his or her Blood Alcohol Content (BAC) is higher than the pre-set level, the vehicle will not start.

Interlocks are also programmed to require a breath sample at random intervals (after several minutes warning, to allow a driver to pull over) while the vehicle is being driven. In addition to preventing the vehicle from starting, the interlock also records data on the use of the vehicle and any attempts to circumvent the use of the interlock, such as roll starting.

When do I install the interlock? 

When you have completed your Behaviour Change Program (as instructed by VicRoads), you must then install an interlock device. After you have installed the device take the documentation back to VicRoads and they will issue you with a Licence .

Interlock Service Locations

All three interlock companies (listed below) have service outlets throughout the Melbourne metropolitan and regional Victoria. There are also outlets in other states.

You will dedicate to one of these service outlets and service the interlock on a monthly basis until the end of your interlock condition.
