- YTYohanes TAug 13, 20265.0I had a great experience with RoadGuard Interlock in Alexandria. Javon and Brian were both incredibly friendly, professional, and helpful throughout the process. They took the time to answer my questions, were patient, and made what can be a stressful process much easier.

- AKAlhassan KamaraJul 15, 20265.0Brian and Jevon have been the best technicians I’ve ever had during this ordeal! They’re sweet! Funny! Fast and efficient! Can’t wait to get to know them over the course of this year with RoadGuard.
- HHHuckMay 25, 20264.0Like others, I struggled with corporate and spotty communication, especially since my install is voluntary. However, my interactions with Brian and his team at the Eisenhower Ave have been grand. They're timely, accessible, and technically accurate.
- BBBrent BevensMay 1, 20261.0Customer service sucks. I called because my device malfunctioned. The guy treated me like I was stupid and had an attitude the whole call
Frequently Asked Questions About RoadGuard Ignition Interlock
How does an interlock device work?
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.
How much does an ignition interlock device cost?
Ignition interlock device costs vary because each state has different pricing regulations and device technology requirements. But in general, you can expect to pay between $50 and $150 to install the interlock device depending on vehicle type. After the initial interlock installation, you are required to pay a monthly rental or lease fee. On average, the cost to rent or lease an interlock device is between $50 and $150 per month. Call us at 1-833-545-0368 for pricing in your area.
