Draeger Ignition Interlock

An ignition interlock device is a breathalyzer installed in your vehicle that measures the level of alcohol in your breath. Connected directly to your vehicles ignition system, you are required to blow into the attached mouthpiece to test your Breath Alcohol Concentration (BrAC). If your alcohol concentration exceeds a specified legal level, the interlock device temporarily prevents your vehicle from starting.
