Rashard is a consummate professional: proficient, adept, responsive, empathetic, and knowledgeable. He offers, hands down, the best customer experience one could possibly hope for when faced with the unfortunate circumstances of having an ignition interlock requirement. I could not have hoped for a better experience, from start to finish. (RoadGuard Interlock customer service is another story, and leaves much to be desired. But that does not affect this review in the least.)

Reshard is the best! This was a stressful/humbling time for me, but he always made it easy for calibration appointments and made you feel comfortable. He also helped with making sure I could get my device off of my car before having to do a huge move to Kentucky, he really helped me and I appreciate it!

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.
