About the Victorian Alcohol Interlock Program

More drink-driving offences require you to use an alcohol interlock when you get your licence* back.

* Licence means any Victorian learner permits and/or driver/motorcycle licence.

What's the Victorian Alcohol Interlock Program?

The aim of the Program is to help you separate drinking from driving. If you get your licence back with an alcohol interlock 'I' condition, you'll have to use a VicRoads approved alcohol interlock.

As soon as you install your alcohol interlock after you get your licence back you'll be a participant in the Victorian Alcohol Interlock Program.

What's an alcohol interlock?

An alcohol interlock is an electronic breath testing device that prevents a vehicle from starting if it detects alcohol. The alcohol interlock will also ask for breath tests during your trip. It records all breath tests requested and any attempts to drive with alcohol present on your breath.

Alcohol interlocks can be installed in most vehicles with an ignition including motorcycles. Only VicRoads approved alcohol interlocks can be used in the Victorian Alcohol Interlock Program and installed by authorised alcohol interlock suppliers or their service agents.


You'll need to use the alcohol interlock for at least the period of time that applies for your drink-driving offence. The data recorded by your alcohol interlock is downloaded at each regular service and is used to make decisions about whether you've successfully completed the Program. Once you prove that you've separated drinking from driving, you can apply to have your alcohol interlock 'I' condition removed. 
  

Who should I contact about the Program? 

We have a dedicated VicRoads Support Centre team for the Alcohol Interlock Program and work closely with alcohol interlock suppliers, drink-drive education & assessment agencies, the Magistrates' Court and Police to operate the Program. If you've got questions about the Victorian Alcohol Interlock Program, contact our VicRoads Support Centre on 1300 723 790 or email [email protected] 

Note: If you have an issue with your alcohol interlock, you'll need to contact your supplier on the support number they gave you when you signed up and installed the interlock.

More drink-driving offences result in an alcohol interlock licence condition

If you lost your licence for a drink-driving offence that happened on or after 1 October 2014, you'll have to use an alcohol interlock when you get relicensed and complete the Victorian Alcohol Interlock Program. You have to meet additional requirements to have the 'I' condition removed from your licence. If you don't follow these rules, the removal of your alcohol interlock will be delayed.

The period your licence is cancelled for and the length of time you'll have to use an alcohol interlock depends on;

  • when your offence was committed
  • the type of offence you committed and your blood alcohol concentration (BAC) reading
  • your age and the type of driver licence or learner permit you had at the time
  • if this was your first offence.

This same information about your offence is used to work out if your relicensing and alcohol interlock requirements are managed directly by us or if you have to go to court.

See our drink-driving penalties page to find out more about drink-driving offences and the penalties that apply.

Stricter rules

If your drink-driving offence happened on or after 1 October 2014, and resulted in your licence being cancelled, you have additional requirements to meet to complete the program and have your alcohol interlock condition removed.

If you don't follow these rules, the removal of your alcohol interlock condition will be delayed.

These same rules apply if you've committed a combined drink and drug-driving offence.

To find out more about the rules of the Program, see Completing the Alcohol Interlock Program.

Alcohol interlocks have cameras

All alcohol interlocks fitted after 30 January 2015 have a camera. The camera takes a number of pictures during each trip, for example when a breath test is recorded to start the car and when it is requested during a trip. These pictures provide a record of who's driving.

It's important you blow in to the alcohol interlock so that the camera can take a clear full face image of you each time. Unless the image clearly shows someone else, it'll be assumed that you're the driver.

Any alcohol interlocks installed before cameras were introduced don't have to be changed or upgraded to fit a camera. Motorcycles are exempt from the requirement to fit a camera.

Not all drivers have to go to court

Not all drivers have to go to court to apply to get their licence back after a drink-driving cancellation.

If your licence was cancelled for your first drink-driving offence that happened on or after 1 October 2014 and your BAC was below 0.10, you apply directly to us to get your licence back.  You have to complete the full cancellation period before you can apply at a VicRoads Customer Service Centre  to get your licence reissued.

Laws allow us to also manage your alcohol interlock requirements. Drivers who are VicRoads managed have a minimum alcohol interlock period of six months. Our team at the Support Centre for the Victorian Alcohol Interlock Program manage your application for removal of the interlock condition once you've met the rules of the program and separated drinking from driving.

The Magistrates' Court will continue to manage repeat drink-drivers and drink-drivers with a BAC of 0.10 or more. Courts also manage more serious and complex drink-driving cases including the combined drink and drug-driving offences. This means you have to go to court to get your licence back and then attend court again, after you've met the rules of the Program, to apply to get your alcohol interlock condition removed.


You can apply for a medical exemption from the Alcohol Interlock Program if:

  • you have a medical condition that prevents you from using an alcohol interlock and
  • you can provide evidence (a report from a medical specialist) that you can't use an alcohol interlock.

If you apply for a medical exemption, we'll also assess whether your health allows you to continue driving.

To apply for an exemption, you'll need to complete the following form:
