The Victorian Alcohol interlock program

Getting your licence back

Find out what you need to do to complete the alcohol interlock program to get your licence back.


You need to complete these steps before you can apply to get your licence back.

Step 1: Fill in the alcohol interlock installation certificate

Download and fill in an alcohol interlock installation certificate (PDF). (You can also get one from a VicRoads customer service centre, by calling 1300 723 790 or emailing [email protected]).

You need to include your client number, found on your behaviour change program certificate of completion and/or any correspondence from VicRoads or Department of Transport and Planning (DTP).

If you don’t have any documentation with your client number on it, visit a VicRoads customer service centre with proof of your identity to get it.

Step 2: Get an alcohol interlock installed

Take the certificate with you when you have the alcohol interlock device installed in your vehicle by an approved alcohol interlock supplier.

The device can only be installed by a DTP approved alcohol interlock supplier.

Step 3: Get your installation certificate signed

The supplier will sign your installation certificate when the interlock has been installed in your vehicle.

This certificate is required to get your licence back.

Step 4: Register to use AIMS

Register to use the Alcohol Interlock Management System (AIMS). The data recorded by your interlock device is saved to AIMS. AIMS is an online portal where you can log in to monitor your interlock usage and track your own progress.

Step 5: Follow the program guidelines

Follow program guidelines and complete the behaviour change program. You can then apply to have the interlock condition removed from your licence.

If you don't follow the guidelines, you'll need to keep the interlock on for longer. The months that you use the interlock don't need to be in a row, but if you don't drive at all for six months or more, then you'll need to start collecting interlock data all over again.

Minimum time with an interlock

The minimum length of time you'll need an interlock depends on:

  • when your offence was committed
  • the type of offence you committed
  • your blood alcohol concentration (BAC) reading (if applicable)
  • if this was your first offence.
