What Is An Interlock?


An ignition interlock is a device which prevents a vehicle from starting if the driver has been drinking. The device works like a breathalyzer, measuring the alcohol in a person’s system. If the amount of alcohol on the driver’s breath exceeds a pre-programmed level, then the interlock temporarily locks the vehicle’s ignition.
