Ignition interlock devices usually include a mouthpiece, the handheld unit about the size of a cell phone or slightly larger. Ignition interlock device accessories include the hook-ups to your vehicle through wiring in order to power the device through your vehicle’s ignition system. Several states require accessories that help the user and the government authorities monitor the use of the device, accessories include a camera, GPS and real-time reporting. It is very important to pay attention to your specific requirements to ensure you are getting the right device for you.
Organizations like Mothers Against Drunk Driving (MADD) champion the use of ignition interlock devices, especially those with requirement technology and accessories in order to protect drivers and keep the roads safe for everyone.

False readings that detect alcohol in your system can cause lockouts where the device will need to be reset. This is a precautionary measure to ensure that those who are intoxicated passed the legal limit are not able to start their vehicle.
It may take a moment for the device to process your blow test. Wait for the notification which can be a sound the device makes or a notification that you have PASSED. This can sometimes take 3-7 seconds depending on the device. Once you receive your passed blow test go-ahead notification, you can start your vehicle and resume driving to your destination. It’s as simple as that!
If your BrAC is below the limit set by your state, your vehicle will start. If your BrAC is above your state’s limit, your vehicle will not start until you submit a breath sample that no longer detects alcohol.
