(AREA) -- A successful pilot program aimed at stopping repeat drunken drivers from further endangering motorists could be used throughout the state under legislation introduced by 81st District State Representative Dan Lauwers of Brockway Township. House Bill 5021 would help institute a sobriety court interlock pilot program throughout Michigan. The program allows repeat offenders to receive a restricted driver license after installing an ignition interlock device on each vehicle the driver owns or operates. The 3-year pilot interlock program in the state is set to end in January 2014. According to an evaluation released by the Michigan Association of Drug Court Professionals, participants had lower drug and alcohol use than nonparticipants.
