An Ignition Interlock Device (IID) is a mechanism, like a breathalyzer, installed in a vehicle to deter drinking and driving. Before the vehicle can be started, the driver must deliver a breath sample into the device, and if the analyzed result is greater than the pre-programmed level, the device prevents the vehicle from being started. Random retests are also required as the vehicle is being driven. When requested, the driver must deliver breath samples into the device and the device will log the event. The Ignition Interlock Device will not turn off the engine.
