How It Works

Breathe

In order to start your vehicle, you must first blow into the device.

Wait

The sensors in the device will determine whether your blood alcohol concentration (BAC) is above or below a preset legal limit. 

Drive

If your BAC is below this limit, you may start your car. If it is above the limit, the device prevents your vehicle from starting.
