Senate Roll Call 691:
Passed

To increase speed limits on rural freeways to 75 mph where engineering studies and traffic patterns indicate this is safe. General speed limits elsewhere would be 70 mph on other freeways, 65 mph on state “trunkline” highways with light traffic, 55 mph on county roads, and 55 mph on unpaved roads except in Oakland and Wayne Counties, where they would be 45 mph. The speed limit on subdivision streets would remain at 25 mph. The bill would revise and simplify various other regulations related to speed limits.
