Ignition Interlock Devices: What You Need to Know

Ignition Interlock Devices: What You Need to Know

One of the many consequences that a person may face if convicted of driving while intoxicated (DWI) is the mandatory installation and use of an ignition interlock device (IID) in their vehicle. Simply put, an IID is an electronic device which attaches to a vehicle’s ignition and prevents a driver from being able to start their car unless they can provide a breath sample which registers a blood alcohol concentration (BAC) under a certain level. In addition, drivers must also provide periodic re-tests while the vehicle is still running.

What Happens If I Fail a Test?

If a driver fails to provide a clean breath test, they will be unable to start their vehicle and a violation will be recorded. If a driver fails a test while driving or fails to provide a clean sample in a timely manner, an alarm will sound and the violation will be logged, with the violation being reported to the police.

In addition, IIDs record and recognize suspicious fluctuations in breath patterns to prevent anyone but the driver from providing a breath sample. Many IIDs will also recognize and record any attempts to bypass the device and hotwire the vehicle.

IID violations may result in a number of consequences, including:

  • A longer period of mandatory IID use
  • Termination of probation
  • Revocation of your restricted license

Statistics have shown that up to one-third of convicted drunk drivers become repeat offenders. By preventing drunk drivers from being able to start their vehicles in the first place, IID devices work to reduce this temptation. According to Mothers Against Drunk Driving (MADD), IIDs are more effective at reducing repeat drunk driving offenses by 67 percent than compared to just license suspensions alone.
