    The handsets are defective the first month I got a violation due to the handset requiring me to retest for 30 minutes straight and now on my second month this exact same thing happen and when I put a request to to have this situation looked I was was told it was my fault even though it was the handset malfunctioning, there is clearly something wrong with the handsets so now I have violation and had to pay extra fees due to the company's equipment working improperly

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.
