    The shop in Springfield VA, the costumer service is just awful. It’s like the technician ( Soon) is doing a favor to the costumer. Awful

    Soon has been great this whole year, very accommodating and great customer service! Made the inconvenience of having to go through the process not so inconvenient! Highly recommend RoadGuard Springfield!

    This review is for the excellent service I received from Soon during my time having a Draeger Ignition Interlock. Let's be honest, no one ever hopes to go through this experience! But, if you must, there's no one who is going to respect your time and work as fast and efficiently as Soon! Every month when I would arrive for my scheduled calibration, Soon would have me in and out in a flash. I appreciate Soon's level of hard work and professionalism so much that after I moved 30 minutes away, I continued to drive to Springfield for my calibrations even though there is a Draeger calibration center closer to my house. So, if you're reading these reviews to find an interlock company and technician that are respectful, reliable, and give consistently good service, choose Soon at Draeger Springfield and you won't be disappointed! - Jennifer Smithmeyer

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.
