Ignition Interlocks Help Reduce Drunk Driving Events

In recent years, study after study has proven that ignition interlock devices (IIDs) prevent drunk driving events. They also have proven that when an IID is installed in a vehicle, the likelihood of repeat offenses is reduced by 50 to 90%.

Research has shown the following:

  • Ignition interlock devices reduce the chances for repeat offenses. Along with treatment, having an IID allows them to form new behavioral patterns by not allowing them to start their vehicle when their Blood Alcohol Concentrations (BrACs) is at or above legal limits as specified by their jurisdiction.
  • Many states have evaluated interlock applications and found the reduction in repeat offenses to be between 50 to 90 percent with an IID installed. 
  • For repeat offenders, several studies show that IIDs may need to be a long-term or permanent condition. There are voluntary programs that allow participants in an ignition interlock program to continue using the device after their program has ended as a way to stay on track. 

Recent studies show:

  • A study in Pennsylvania found that DUI deaths decreased by 15% in states that enacted all-offender interlock laws. 
  • A study in Illinois found that participants in their interlock program had an 85% reduced rate of repeat offenses.
  • A study in California found that Ignition interlocks are 74% more effective in reducing DUI repeat offenses than license suspension alone for first offenders.
