What is an Ignition Interlock Device (IID)?

Ignition interlock devices (IID), are sometimes referred to as breath alcohol ignition interlock devices (BAIID), or car breathalyzers.

An IID is a small device that’s installed directly into a vehicle's ignition system. Once it is installed, the device prevents any driver from starting the car while intoxicated.

How Much Does an Interlock Device Cost?

Monthly lease fees cover the use of the device and the monthly reporting required by all states. The cost for devices can vary depending on state requirements, like a camera or GPS. Our advisors can help determine your total costs and what device meets your state’s criteria.
