Ignition Interlock Device Frequently Asked Questions
Ignition interlock device basics
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.
Ignition interlock devices and drunk driving laws vary from state to state. After a DUI, you may be able to get your license reinstated by having an ignition interlock device installed in your car.

How to use an ignition interlock device
Yes, as long as they are not driving under the influence and are covered by insurance. However, they must provide a breath alcohol test before the vehicle will start and take retests throughout their trip. You should check with your legal advisor for additional guidance on this.
Anyone who drives a vehicle with an interlock device must provide a breath test, even if they are not the owner. If they have a violation, please contact your monitoring authority for guidance.
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. RoadGuard Interlock devices will beep to notify you of a rolling retest and give you a few minutes to stop your vehicle in a safe place and provide the retest.
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.
Keep products containing alcohol like hand sanitizer, mouthwash, hairspray, perfume, etc. away from the device. Do not consume any food, beverages other than water, or tobacco products within 15 minutes before taking a breath test.
We do not change the standard ignition interlock breath volume setting unless we receive (1) written approval from the court or jurisdiction to lower the breath sample volume or (2) documentation from a licensed physician verifying diminished lung capacity and the need for lowered air volume for a breath sample. 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.
RoadGuard Interlock devices guide you with step-by-step instructions on how to provide a correct breath sample. Once your car is turned on, you just blow in, quickly suck back, and then you are on the road in as little as 10 seconds.
No. While other devices make you breathe and hum in specific patterns, RoadGuard Interlock devices use an easy blow-suck breath pattern for the test. With one of the fastest warm-up times in the industry, our interlock devices get you back on the road in as little as 10 seconds.

Your mechanic can perform repairs and maintenance as usual on your vehicle while your RoadGuard Interlock device is installed. However, you need to let your mechanic know you have an ignition interlock device on your vehicle so they can request an access code to bypass breath testing. To request an access code, mechanics must complete the Access Code Request Form. Access codes are dependent on state regulations. Before proceeding, you should check with your service technician to see if access codes are permitted in your state.
If your vehicle’s battery dies or is disconnected, the interlock device will record the event as a potential violation. If you take your vehicle to a repair shop to have the battery recharged or replaced, record the time that the battery died and make sure to keep receipts. If you replace the battery on your own, keep the receipt from the new battery purchase, record the time the battery died and the time your vehicle successfully started.
