How it Works

Step 1
To submit a breath sample, exhale into the mouthpiece for around 3 seconds at steady volume, just like blowing out candles on a birthday cake, until you hear the device click.

Step 2
The ignition interlock device will internally read your breath alcohol content (BrAC) and will flash the results on the screen.

Step 3
If your BrAC is below your state’s legal limit, you’re ready to hit the road and it will allow your car to start.
