Alcohol Interlocks

If your offence occurred on or after 30 April 2018, visit the VicRoads website for more information.


If you have an alcohol interlock installed in your car, you will have alcohol interlock condition imposed on your licence. This means you can only drive a motor vehicle where an alcohol interlock has been installed by an approved supplier.

Information about approved alcohol interlock suppliers can be found on the VicRoads website.

 

An alcohol interlock is an electronic breath testing device that prevents a vehicle from starting if alcohol is detected.


For more information about alcohol interlocks, including costs and installations, visit the VicRoads website


You may have an alcohol interlock condition placed on your licence if you have been found guilty of:
 

  • a drink driving offence
  • a combined drink and drug driving offence
  • offences that were found to have occurred under the influence of alcohol or both alcohol and a drug.

The following tables outline when an interlock condition must (mandatory) or may (discretionary) be imposed.

Removing an alcohol interlock

You will need to apply to have an alcohol interlock condition removed from your licence.

An alcohol interlock condition managed by the court is called an alcohol interlock condition removal order (AICRO). 

If your alcohol interlock condition is managed by VicRoads, visit the VicRoads website.

The removal of a court ordered alcohol interlock condition may be delayed if you: 

  1. don’t drive the vehicle at least two times a month
  2. don’t drive the vehicle at all for six months in a row
  3. tamper with the alcohol interlock.

However, the court can ask about other matters even if the minimum requirements above are met.

A judicial officer also has discretion to ask for more information before issuing an AICRO. 

Step 1

Visit your nearest Magistrates’ Court and submit an application for an AICRO. Applications are made in person to a court registrar who will record your details. 

A court hearing date will be made at least:

  • 28 days after you have submitted an AICRO application
  • two weeks after your alcohol interlock condition period has ended.

An AICRO application cannot be heard until the original alcohol interlock condition has expired.   


The court will also advise the police, who may interview you before the court hearing date.

Step 2

Offence committed before 1 October 2014


Within 28 days of your court hearing date you will need to:

  • visit your alcohol interlock supplier – the approved agency that installed the interlock - and ask for the interlock’s data to be downloaded and a compliance assessment report sent to your nominated accredited agency (the assessor).
  • get an assessment report from your nominated accredited agency (your assessor). Once you have been assessed, the report will be sent to the court on your behalf. The report helps the judicial officer decide whether your alcohol interlock condition should be removed. 

Offence committed on or after 1 October 2014 but before 30 April 2018

After your alcohol interlock condition period ends and within 28 days of your court hearing date, you will need to:

  • visit your alcohol interlock supplier – the approved agency that installed the interlock - and ask for the interlock’s data to be downloaded and a compliance assessment report sent to your nominated accredited agency (the assessor).
  • request your interlock removal criteria report from the VicRoads Alcohol Interlock Management System (AIMS).  You must also ask VicRoads to send a copy to your nominated accredited agency (your assessor).

AIMS is an online portal to help you complete your alcohol interlock order. For more information, visit the VicRoads website

  • get an assessment report from your nominated accredited agency (your assessor). Once you’ve been assessed, the report will be sent to the court on your behalf.  The report helps the judicial officer decide whether your alcohol interlock condition should be removed. 

Offence committed on or after 30 April 2018

  • Complete a behaviour change program. You must provide the court with a certificate of completion if you are required to complete a behaviour change program.  VicRoads will advise you whether you need to complete a further behaviour change program to remove the interlock condition on your licence.
  • You may also need to provide an AIMS report and get your interlock device data sent to the Court to support your application. However check with VicRoads for your requirements.

Step 3

Attend court on your hearing date, making sure the Court has a copy of your:

  • certificate of completion of the behaviour change program – (if you have been required to do a behaviour change program)
  • any other important documentation to support your application (may include AIMS report, data from your interlock device and an assessment if your offence was committed pre 30/4/18)

Step 4

If the judicial officer grants your AICRO, you can take the order to a VicRoads customer service centre to have the alcohol interlock condition removed from your licence.
