TIRF USA to participate in evaluation of the ignition interlock program in Minnesota



The Traffic Injury Research Foundation USA (TIRF USA) and VHB, Inc. have been contracted by Greenway Transportation Planning to participate in an evaluation of the ignition interlock program in Minnesota. The goal of this project is to examine the effectiveness of the ignition interlock program in Minnesota and to provide a comprehensive report to the Minnesota Department of Public Safety, Office of Traffic Safety.

Following the implementation of a pilot ignition interlock program, Minnesota implemented a statewide ignition interlock program in 2011. The two primary goals of the program are to prevent impaired driving and reduce DWI re-offenses. This evaluation is critical as it represents the first evaluation of the program since its statewide implementation.

The evaluation will include advanced statistical analysis to determine if the program is having the desired effect of deterring motorists from driving while impaired and thereby enhancing road safety. Program participation rates as well as profiles of program participants will be explored. The evaluation will identify characteristics of those drivers most likely to complete the program successfully and those who are most likely to continue to attempt to drive while intoxicated despite the interlock being placed on their vehicle. The study will also provide information on recidivism rates for those all individuals who are eligible for the interlock program.

The evaluation is expected to be completed in September 2015.
