    Even with this being a bad first experience getting a DUI, Scotty made the process better. His personality and professionalism makes you feel very comfortable and at ease. I've heard so many complaints about a lot of other companies, but reading the reviews on scotty is what made me decide to choose RoadGuard. If youre ever required to have an interlock put into your car, I would whole heartily recommend Scotty and Roadguard to make the experience a little bit easier. 5 stars all the way⭐️⭐️⭐️⭐️⭐️

    Scott at roadgaurd was awesome. Considering we get ourselves in these situations he handled all my appointments and calibrations professionally and politely. He worked with me when I would have to be late for appointment or reschedule one. Don't give these guys a hard time .. because at end of day we did this to ourselves.

    I was a customer at Roadguard Lynchburg Virginia for 21 months. The two techs at that location were excellent. Scott and Jeff were always very professional when getting calibrations. The most impressive part for me was, as life deals us all a curve from time to time, they would answer my calls anytime and offer help for what I needed. Change calibration times, even helped me find a location when I needed service quickly. These guys are great. Thank you Scott and Jeff for making a difficult part of my life much easier and less stressful.

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.
