The best interlock for over 30 years.

What is a Interlock device?

The ignition interlock device (IID) is a small handheld breathalyzer for cars that measures alcohol concentration in the breath. 

The vehicle will not start if the IID registers a breath test result (BAC) that exceeds the pre-set limit. When the driver blows beneath the predetermined limit, the vehicle will start. 

Why Would I Need One?

Following an arrest for drunk driving (DUI, DWI, DUI, OWI, or OVI), installing a BAC monitor is a common requirement.

State laws determine how often these appointments occur; however, on average, they happen every 30, 60, or 90 days.
