There have been many studies which have explored the effectiveness of ignition interlock devices for DUI offenders over the last 20 years. Again and again the research has proven that interlock devices reduce recidivism by 50 to 90 percent when installed and maintained on an offender’s motor vehicle.
Research has conclusively shown the following:
- Ignition interlock devices reduce recidivism among both first-time and repeat offenders, including “hardcore” offenders—those offenders who repeatedly drive after drinking with high Blood Alcohol Concentrations (BACs) and are resistant to changing this behavior.
- More than 10 evaluations of interlock applications in various states have demonstrated reductions in recidivism ranging from 50 to 90 percent while the interlock is installed on the offender’s vehicle.
- Once ignition interlocks are removed from vehicles, recidivism rates of ignition interlock users are similar to the rates for offenders who did not install ignition interlocks. Because of the increased recidivism rates following the removal of an interlock device, several studies have reported that interlocks may be necessary as a long-term or permanent condition of driving for repeat offenders.
Some specific research studies found the following:
- A study in New Mexico found that participation in their interlock program reduced recidivism by 50 percent.
- A study in Maryland found that participation in their interlock program reduced recidivism by almost 65 percent.
- A study in Illinois found that participants in their interlock program had a reduced recidivism rate of 85 percent.
