What is an Intoxalock Car Breathalyzer or IID?

An Intoxalock ignition interlock device is an alcohol breathalyzer that connects with your vehicle’s ignition system. In order to start a vehicle with an Intoxalock IID installed, you must not have a breath alcohol concentration (BrAC) level above the legal standard for your state.

How do I use an Intoxalock IID?

To use an IID, blow through the mouthpiece for approximately 5 seconds. The device will indicate when to stop blowing and when to start your vehicle. If your breath sample is below the legal limit allowed by your state, then your vehicle will start as normal.
