What is an ignition interlock (IID)?

An Intoxalock ignition interlock device is a state-of-the-art breath alcohol monitoring device that integrates a fuel cell based breathalyzer with your vehicle’s ignition system. When a breath sample is submitted, Intoxalock tests the sample for the presence of alcohol. Using a fuel cell technology developed by Intoxalock for the ignition interlock industry, the device will display the breath alcohol concentration (BrAC) of the sample on the LED screen. * If the BrAC is below the legal standard for your state, the vehicle will start. If a violation is detected, the vehicle will not start until a safe sample has been provided.

High standards reduce complaints

State and Federal mandates require that most ignition interlock devices be calibrated every 30 to 60 days. In independent studies and approved by the State of Iowa, the Intoxalock has been proven reliable for over 180 days. It is currently the only ignition interlock device to achieve this high standard, which increases customer convenience and reduces Intoxalock complaints vs. other ignition interlock companies.
