      How Ignition Interlock Devices Work

      What is an Ignition Interlock Device?

      An ignition interlock device is a breath alcohol analyzer connected to the ignition of a car, also known as a handheld car breathalyzer. You may be required to install an ignition interlock device in your vehicle after receiving a DUI offense. A vehicle equipped with an ignition interlock device cannot be driven unless the driver passes the unit’s breath alcohol tests.

      Ignition interlock devices significantly reduce the amount of drunk driving accidents and DUI penalties by preventing the car from starting if the driver is too intoxicated.

      Our state of the art ignition interlock devices are easy to use.

      Ignition Interlock Device Features

      • Easy-to-read digital displays and video sampling indicators
      • Detachable, lightweight handheld device to provide discreet mounting options
      • Quick and convenient calibrations with daily reminder of next calibration date
      • Simple, bilingual voice commands, and tone prompts

      Install

      Ignition Interlock installation takes 1-3 hours, depending on your car make and model. Find an installer near you.

      Drive

      Simply blow into the ignition interlock device before starting your vehicle. If the sample meets the state requirement, it will start.
