What is an Ignition Interlock Device (IID)?

An ignition interlock device (IID) or breath alcohol ignition interlock device (BAIID) can prevent a driver from starting a vehicle if the driver’s breath alcohol concentration (BrAC) is above a pre-set fail level. Similar to a breathalyzer, the IID analyzes the breath sample provided by the driver to determine the BrAC. If the BrAC is under the pre-set fail level, the IID will allow the ignition of the vehicle to start the engine. If a valid breath sample is not provided, or if the BrAC is at or above the pre-set fail level, the ignition will be disabled thus preventing the engine from being started.
