The Interlock Program

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 before you get your license back.
