House Fiscal Agency Analysis

House Bill 4132 would amend the Michigan Vehicle Code to allow the Michigan State Police (MSP) and the Department of Transportation (MDOT) to install and use automated speed enforcement systems in work zones on highways or streets under the jurisdiction of MDOT. An automated speed enforcement system would mean an electronic traffic sensor system that does both of the following: automatically detects a vehicle exceeding the posted speed limit with a type of speed timing device and produces a recorded image of the vehicle exceeding the speed limit that shows a clear and legible identification of the vehicle’s license plate and the location, date, and time the image was taken. House Bill 4133 would make complementary changes to the Revised Judicature Act.
