What is an Ignition Interlock Device?

An Ignition Interlock Device (IID), also called a car breathalyzer, is typically installed in your vehicle as part of a legal requirement after drunk driving. It’s small and discreet – about the size of a cellphone – and it’s located on the driver’s side of your vehicle.

Smart Start’s handheld car breathalyzer unit includes a cord that’s long enough to let you move the device freely. If it’s required by your state, you’ll also have a camera that verifies your identity during testing

Is an Interlock Device easy to use?

Using an Ignition Interlock is easy. Blow into the device for three or four seconds while humming at the same time, and you’ll hear a click that signals the test is complete.

Depending on state laws, our car breathalyzers support a “blow-and-hum” technique to confirm that it’s a real person taking the test. Blow-and-hum is more sanitary and less complicated than a blow-inhale-blow pattern used by car breathalyzers from other companies. You can also help keep your device sanitary by cleaning or changing out the mouthpiece regularly.
