Massachusetts ignition interlock device state laws FAQs

An ignition interlock device is a breathalyzer that is installed in your vehicle to prevent drinking and driving. It is made up of a mouthpiece, a handheld unit and a cord that attaches to your vehicle’s ignition system. You are required to blow into the mouthpiece to test your Breath Alcohol Concentration (BrAC) before starting your car. For more information see our what is an interlock page.
