An evaluation of Michigan's repeat alcohol offender laws: executive summary

Encouraged by the positive effects of its 1992 drunk and impaired driving laws on first-time drunk-driving offenders, the Michigan legislature turned its attention to reducing the incidence of repeat drunk driving and driving with a suspended or revoked license. On October 16, 1998 the Michigan legislature passed a package of 20 bills to address these problems. These laws, implemented on October 1, 1999, were designed to aid law enforcement in separating multiple offenders from their vehicles, to strengthen legal consequences for repeat alcohol offenders, and to provide uniform licensing actions and treatments. The University of Michigan Transportation Research Institute was selected to evaluate the impact and effectiveness of Michigan's repeat alcohol offender package of laws. This executive summary of the final report summarizes the project results and conclusions.
