The IID is connected to your vehicle’s ignition system. Before starting your car, you must blow into the mouthpiece. If your breath sample is alcohol-free or below the preset limit, the engine will start. If not, it stays locked.

Rinse your mouth with water, then provide a clean breath sample into the device. If your BrAC is within the limit, you can start the vehicle. While driving, the device may prompt random retests to ensure continued sobriety.

If you fail a test before starting the vehicle, the engine will remain locked. You may have to wait before retrying. Multiple failed attempts can result in a lockout, requiring you to return for service.
