Your partner in getting back on the road

For over 25 years our goal has been to help customers regain their independence by getting them back on the road safely, quickly, painlessly, and affordably. Our devices are specifically designed to not get in your way, so you can spend more time driving safely and less time interacting with the device.

Where you are,
with the help you need

Our customer service center is here to help 24 hours a day and 7 days a week. Our devices are backed by an extensive network of service centers with qualified technicians here to support you every step of the way. We are one of only a few companies that provide roadside assistance, and most of our locations offer onsite repair should you need it.

They’re ready before
you are

While other devices make you breathe and hum in specific patterns, RoadGuard Interlock devices use an easy blow-suck breath pattern to complete 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.

Committed to making the road safer.
