Ignition interlock deviceWhat is an Ignition Interlock Device?

An Interlock is a breath alcohol analysis device that is installed in a motor vehicle. The Interlock prevents an alcohol-impaired person from starting the motor vehicle. Retests are randomly required during operation of the vehicle. The Interlock system records dates, times, test results, engine runs and engine offs. This data is provided to designated authorities and used to determine compliance with the Interlock program.

Will the unit shut off the engine?

No. An Interlock does not shut off a vehicle’s engine, or stop it abruptly in its tracks. If a Retest is failed, or if the Retest is not presented when required, a violation will be recorded. The vehicle’s horn will sound and the lights may flash until either the breath test is passed or the vehicle is turned off by the driver.

What happens if you use mouthwash before blowing into Ignition Interlock?

Most likely the device will register alcohol if the mouthwash has alcohol in it. We advise you not to eat, drink or smoke for at least 5 minutes before the test, and do not use mouthwash for at least 15 minutes before the test.

Will other people be able to drive the vehicle with Interlock in Ontario?

Yes, however there is no way of verifying that you were not the person driving the vehicle. This means that you become responsible for everything that the unit records. If another person was driving the car you are still responsible for any consequences that arise if that person was drinking.

How often will the interlock in Ontario need to be monitored?

The monitoring time interval can vary , but in Ontaraio the interlock is monitored at the service center every eight (8) weeks. This monitoring and calibration check will take approximately fifteen (15) minutes.

Can’t someone besides the driver provide the test?

Yes. A non-compliant user might request that someone (a stranger, family member, older child) provide a passing breath sample. The Interlock Device does not positively identify the driver. The Retest feature, however, requires subsequent random breath samples during the journey, and shortly after the engine starts.

What happens if you have repair work done on a car with the Interlock device in Ontario?

You should inform Interlock Device company prior to having the vehicle worked on.
