It’s an electronic breath testing device connected to a vehicle’s ignition system. The vehicle does not start unless the driver blows and passes a breath test. Often an Interlock Device is required by law if you have been charged with a drink driving offence, if that is the case just get in touch with us to get help.

Every Interlock device MUST be serviced regularly to guarantee an accurate reading and it is required by law.


The program is designed to help drivers separate drinking and driving. It does this by keeping offenders in the licensing system on a closely monitored basis, with the interlock physically preventing drink driving.

A participant’s breath test results are recorded by the interlock and monitored by Roads and Maritime during the interlock period. This is so Roads and Maritime can be confident that a participant has learnt to separate drinking from driving, and can safely drive without the need for an interlock.
