What is an Ignition Interlock Device?

Most people are required to install an ignition interlock device after a drunk driving conviction. Voluntary alcohol monitoring options are also available to help guarantee sober driving.

An ignition interlock device often referred to as a car breathalyzer, is a small, hand-held breathalyzer that is installed in your car. The device has a mouthpiece in it that you will blow into before starting your car. With a clean breath sample, you’ll immediately be able to start your car.

Intoxalock’s state specialists are ready to answer your questions and help you through the process, one step at a time. It takes less than 10 minutes.
