Guardian Interlock Device Image

The Guardian ignition interlock device can get you back onto the road safely and legally after a DUI arrest. The device is a breath analyzer that is attached to the ignition system of your vehicle. In order to start your vehicle, you must first blow into the device. The device’s sensors determine whether your blood alcohol concentration (BAC) is above or below a preset legal limit. If it is below this limit, you may start your car. If it is above the limit, the device prevents your vehicle from starting.

Our device is one of the easiest-to-use systems available. The latest fuel cell alcohol-specific technology ensures that it provides the most accurate test results. It is also one of the smallest and most discreet devices on the market. It even has a removable handset that can act as an additional vehicle anti-theft device.
