- BHBig Hubb98Aug 15, 20195.0Eman was great to work with! So glad I made the decision to go with Draeger. From the very first day I was made to feel welcome and like a friend. The installation was quick and the machine was easy to use. I spent 11 months working with Eman and during that time he was always professional, courteous and prompt. I would definitely recommend this place to others.
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.
