How to use the device, how they work, pricing and costs, choosing the best provider and device for you and more. An ignition interlock device, or IID, is a small device that connects into the ignition of a DUI offender’s vehicle that measures a user’s breath alcohol concentration (BrAC). An IID prevents a vehicle’s engine from starting until the user has provided a breath sample that is below the legal limit set by your state. If the driver’s breath sample is above the state limit, the vehicle will not start. Drivers with an IID must periodically provide breath samples throughout each trip to verify the absence of alcohol. Additionally, ignition interlock devices track the user’s activity and provides a record of any violations to your state’s monitoring department.
