What’s an ignition interlock device?

An IID is a hand-held breathalyzer installed in your vehicle that prevents it from starting if alcohol is detected. It’s commonly required after a DWI to help you meet state requirements, regain your license, and get back on the road.

Top 7 Intoxalock tips

Get the most out of your breathalyzer and avoid violations and lockouts by following these helpful steps.

  1. 1

    Practice the correct breath pattern

    Perform several successful tests before leaving your installation appointment.

  2. 2

    Be prepared for retests

    Your IID may request a random retest while driving. You’ll have at least 5 minutes to safely pull over and take the test.

  3. 3

    Monitor the IID while you drive

    Make sure you can see and hear your breathalyzer to notice alerts.

  4. 4

    Wait 15 minutes after eating and drinking

    Some food and drinks can contaminate your breath.

  5. 5

    Do one last check when you park

    Before exiting your vehicle, check to see if your IID has issued a final retest.

  6. 6

    Know how to find helpful information

    Check the Intoxalock app or your MyAccount online for additional resources.

  7. 7

    Calibrate your device on schedule

    Book your required calibration when the recommended window of time opens.
