The ACT Alcohol Ignition Interlock Program is both a Mandatory and Voluntary Interlock Program – Mandatory for prescribed offenders after a court direction, and following 50% of your initial suspension period. Voluntary participation is available (immediately) to suspended drivers who wish to drive during your suspension period (these are people who don’t fall into the mandatory category). You will need to apply to the RTA for your I-condition licence, nominating a vehicle by completing an Application for a Probationary Licence with an Alcohol Ignition Interlock Condition form. All participants are required to have the interlock fitted for 6 months. Participants will need to have demonstrated safe driving behaviour and the ability to separate drinking from driving before being eligible to hold a licence without an interlock condition.

The ACT program is overviewed by Transport Regulation (RTA). For advice on licencing please contact RTA on 02 6207 7002.

FAQFrequently Asked Questions

How much will it cost?

Initially you need to pay for the installation 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 are paid monthly. 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.

Can I have it fitted to any sort of vehicle?

Yes – Depending on your vehicles make, model, and year, interlock device installation can vary. Motorbikes require a compatible ignition system and battery, kick start motorbikes will not be fitted.

Our service centre will inspect your vehicle and advise you of any additional costs.

What will I need to bring with me on the day?

You will need your licence receipt, photo ID, concession card (conditions apply) and motor vehicle. The owner’s permission is always required. Click here to have the registered owner complete their authority form.

How often do I have to be serviced?

Monthly (30 days)

How do I complete the program?

For further information visit the RTA website.

Are there any other exemptions?

There are limited exemptions available. You should contact the RTA to see if you qualify.

Can anyone drive the vehicle after an interlock device has been fitted?

Yes, anyone can drive the vehicle but you are responsible for what is recorded on your log.

I’m selling my car, what should I do?

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.

I Can’t Afford My Interlock Anymore, What Can I Do?

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.
