State Interlock ProgramsVIC Interlock Program

Initially you need to pay for the installation, VicRoads Cost Recovery fee and the first month’s lease fee for the interlock which is leased on a monthly basis. The overall cost of installation will be determined by the vehicle type (standard or non-standard installation), and length of program. Then lease fees and the Cost Recovery fee are paid monthly. The VicRoads Cost Recovery fee is a government fee imposed to recover the costs of running the Interlock Program. You also have a Loss Protection Plan option, which reduces your liability if the equipment is stolen. A Removal fee is charged at the end of the program. A list of our fees is available on this website.

The Victorian Interlock Program is not the subject of any government subsidy schemes and there is at present no financial assistance available to drivers that are required to complete the program.

Nevertheless, Guardian Interlock have offer a number of ways to ensure the costs incurred throughout the program are kept to a minimum, and these will be discussed by our team members at your service centre. Adhering to the guidelines set out in the program is always advised to ensure no additional costs are incurred.

Interlock periods in VIC vary with a minimum period of 6 months. VicRoads will advise you of your interlock period once you’ve had your interlock installed and licence reissued.

You must attend your installation appointment to have your reference image captured and complete training. Once installed someone else may present your vehicle for service.

Your alcohol interlock device will need to be serviced monthly (every 30 days). At this time, service technicians will also analyse the data recorded by the device to ensure the driver has been adhering to the guidelines of the program.

Participants have to demonstrate that they can separate drinking and before they will be eligible to hold a licence without an interlock condition. If you have completed your interlock period you can apply online through VicRoads AIMS portal or call VicRoads.

Yes, you can apply to VicRoads for a medical exemption if you have a condition that prevents you from using the alcohol interlock.

Yes, anyone can drive the vehicle but you may still be responsible for what is recorded on your log. The interlock camera captures images of anyone using the interlock.

Make an appointment with your service centre to transfer the equipment from one vehicle to another. If you do not have your new vehicle yet you may have the interlock removed voluntarily.

Voluntary removal will incur an additional Early Termination Fee. This fee will be refunded provided you have your interlock reinstalled with Guardian within 6 months. The period where the interlock is not installed does not count towards your program.

The best plan is to have the interlock removed until you are able to afford it. Removal and reinstall charges will apply but the lease costs continue and can end up costing you more than the removal/install. In most states an early termination fee also applies but is refunded if you return within 6 months.

It is a good idea to contact Guardian for advice if you are having difficulties to avoid unwanted additional fees and your account being escalated. We will do our best to work with you to assist in difficult situations.
