Mandatory Interlock Program

What is an Interlock device?

Interlocks are electronic breath testing devices linked to the ignition system of your car, motorcycle or truck. Once the device is fitted in order to start your vehicle you need to breathe into the interlock device. Your breath is then analysed for the presence of alcohol. If alcohol is detected you will not be able to start your vehicle. If alcohol is not detected you will be able to start driving, however, randomly timed breath tests will occur when you are driving and you must also pass these tests to continue driving.

In NSW all Alcohol Interlock Program participants must have a zero blood alcohol concentration when driving.

The Interlock device records all the breath test results, takes a photograph of the person providing the sample and records any attempts made to tamper with the device.

If you are convicted of a mandatory interlock offence as defined in Section 209 of the Road Transport Act 2013 an Interlock Order will be issued by the Court. If you fail to comply with this order you will be disqualified from holding a licence for a period of five years from the date of your conviction.
