The Alcohol Interlock Scheme is a legislated Scheme that allows drivers disqualified for a relevant drink driving offence to apply to the Registrar of Motor Vehicles for an Alcohol Interlock licence at any time after the half way point of their disqualification.

An Alcohol Interlock Scheme – Information Pack (PDF) has been prepared for potential Scheme participants, who have been convicted of a relevant drink driving offence and disqualified from holding or obtaining a driver’s licence for six months or more. The information pack is also available from any Customer Service Centre

An Alcohol Interlock is a small breath-testing device, about the size of an electric shaver, which can be fitted to your vehicle. It measures your breath alcohol level when you blow into it, allowing you to drive legally, but preventing you from driving after drinking alcohol.

The Alcohol Interlock Scheme gives you mobility and the opportunity to maintain employment, while at the same time providing the public with the assurance that you will only be able to drive when there is no alcohol present in the blood.

South Australia is the first state in Australia to establish an Alcohol Interlock Scheme for persons convicted of drink driving. Examples of successful interlock schemes can be found in the United States, Canada, and Sweden.
