Ignition Interlock Devices with GPS Tracking

Ignition interlock devices are very effective tools in preventing drunk driving. Each year, the devices stop hundreds of thousands of drivers during attempts to drive with alcohol in their system. The devices require the driver to take a Breath Alcohol Content (BrAC) test and pass before they can start their car. Many states use these devices as a penalty for drunk driving in an effort to make roads safer, and prevent relapse.

Interlock users and people who ride with them may be wondering what type of information the devices collect, how they collect it, and why. Many states require the interlock device offenders install to have integrated GPS tracking. 

The GPS technology helps track the locations users are providing breath samples in real-time. Depending on the state, the device may also record the location and report any violations. State monitoring authorities collect this data and in states with compliance-based interlock policies, violations can result in increased interlock terms. This means that if multiple violations are recorded, the state may require the offender to have their interlock for longer than initially required.

Ignition interlock devices collect a variety of data, even if they do not collect GPS data. This data includes: 

  • Each breath sample provided and the BrAC result
  • Location of the car
  • Every calibration completed
  • Missed calibrations
  • Attempts to tamper with the device

This information is stored and typically reviewed by the state monitoring authority. The data is provided to the monitoring authority and they review it to ensure offenders are following interlock requirements. The GPS data is not used for other purposes and any private data is not shared outside of the monitoring authority.
