What is an ignition interlock device?

 

A: An ignition interlock device (IDD) is a breathalyzer that is installed in a vehicle, which will prevent the vehicle from starting unless the machine’s breathalyzer registers the driver’s blood alcohol as below the legal limit. It also requires random tests after the car is started. IDDs are commonly required as a condition of probation, once a person’s driver’s license has been reinstated.
