When you start your vehicle, you have to blow into a mouthpiece that’s connected to the ignition interlock device, sometimes called an in-car breathalyzer. The interlock device will then measure your breath alcohol concentration (BrAC) and automatically determine whether your BrAC is low enough to allow the car to start. Any test you take, whether pass or fail, will be reported to your monitoring authority.

It depends on your specified legal level. You are required to blow into the interlock mouthpiece, which is directly connected to your vehicle’s ignition system, to test your Breath Alcohol Concentration (BrAC). If your alcohol concentration exceeds your specified legal level, the device temporarily prevents your vehicle from starting.

To make sure that the driver stays sober while driving, you or the driver will have to take a rolling retest at some point during the drive. The rolling retest – also called a “random retest” — occurs at random times throughout your trip.

Some foods, beverages and even alcohol-based mouthwash can cause a failed breath test in some ignition interlock devices. However, RoadGuard Interlock devices minimize this problem because they can tell the difference between breath alcohol and mouth alcohol, such as mouthwash.

In some cases, additional approval from the state authority is also required. Once the required authorization is received, RoadGuard Interlock will lower the volume to the minimum amount sufficient for effective operation of our devices.

Some states or counties require that an interlock device be equipped with a camera. Images these cameras can prove the identity of the person who is providing the breath sample. The camera only takes a picture when the driver provides the breath sample. Since the camera only works when the ignition interlock device is being used, it does not photograph the driver while the vehicle is in operation.
