What is an ignition
interlock device (IID)?

An ignition interlock device (IID), also known as a car breathalyzer or “blow and go,” is a small handheld unit connected to a vehicle’s ignition system that measures breath alcohol levels before allowing the engine to start. Required after DUI or similar offenses, IIDs prevent driving if alcohol is detected and may require retests during trips, though they never stop a moving car. Programs vary by state but often involve licensing, installation, testing, calibration, monitoring, and eventual removal. LifeSafer, a premier provider with nearly 2,000 convenient locations, ensures professional installation and servicing through extensively trained local technicians who can answer all your questions.
