What Is An Ignition Interlock Device?

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.

Why Would I Need One?

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.


With one-button activation, easy-to-read LED display, and fast warm-up time, Intoxalock redefines ease while keeping you and your community safe. Besides being programmable in English and Spanish, the device offers easy blow patterns with no humming required. 

How Do I Get It Installed?

It is determined by the state's legal requirements and the specifics of your DWI/DUI/OWI case which type of ignition interlock device you receive.

Installing, calibrating, and maintaining a successful program starts with a licensed expert. We can help you get started.
