How to Use an Ignition Interlock Device
An ignition interlock device is a breathalyzer installed in a driver’s vehicle that measures the level of alcohol in your breath. Connected directly to your vehicle’s ignition system, you are required to blow into the attached mouthpiece to test your Breath Alcohol Concentration (BrAC). In the case your alcohol concentration exceeds a specified legal level, the interlock device temporarily prevents your vehicle from starting.
Start your car and your
device will power up.
Take a deep breath in. Blow steadily.
When the tone changes,
take a deep breath in.
Your results will appear in seconds.
The interlock test has passed,
you’re free to go!
