An Interlock is a breath alcohol analysis device that is installed in a motor vehicle. The Interlock prevents an alcohol-impaired person from starting the motor vehicle. Retests are randomly required during operation of the vehicle. The Interlock system records dates, times, test results, engine runs and engine offs. This data is provided to designated authorities and used to determine compliance with the Interlock program.
An ignition interlock device is an in-car alcohol breath screening device that prevents a vehicle from starting if it detects a blood alcohol concentration (BAC) over a pre-set limit. The device is located inside the vehicle near the driver’s seat, and is connected to the engine’s ignition system.
