What is an alcohol ignition interlock?
An alcohol interlock is a breathalyser which is wired into your car’s ignition which records every start, stop, test result, violation, km’s driven etc which is then available as a report for authorities to view.
Before you start your vehicle you will need to provide an alcohol free breath sample.
Once you have passed the test you can then start your vehicle.
While you are driving your interlock will call for random tests which must be taken, otherwise this is classed as a violation.
Each month you need to take your vehicle back to a service centre to get the data downloaded and the interlock calibrated, this takes about 15 minutes, monthly payment is made at the time of the service.
How do I know if I am okay to drive the morning after drinking?
The only real way of knowing is to test yourself on an accurate personal breathalyser, for more information visit here.
This is useful to check your alcohol level BEFORE you blow into your interlock, potentially causing a violation.
Don’t use your interlock device as a tool to test yourself so you know what you alcohol level is, this will be recorded as a violation which may potentially extend the length of time you have your interlock installed.
How much will an interlock cost me?
If you’re eligible for the alcohol interlock subsidy it will only cost you $133 per month to lease an interlock.
If you’re not eligible for the subsidy, Standard pricing is $183 per month to lease an interlock, plus installation and removal
If you have been through an Alcohol & Other Drug Treatment Court you may be fully funded by Corrections. Call us on 0800 002 182 to find out more.
Additional fees may apply if you do not adhere to the requirements.
Can I start my vehicle without taking a test?
No, your vehicle will not start without a test.
What will interlock look like in my vehicle?
The interlock device will look very similar to a breathalyser except it is attached to your vehicle.
It is roughly the size of your hand and can either be mounted on a clip on your dashboard or stored near your gear lever.
It does not need to be visible to anyone outside your vehicle.
Will installation of the interlock device damage the vehicle?
No. The unit is only connected to the wiring under the dash and under the bonnet.
At the end of the programme, this wiring is restored to pre-installation conditions.
