MI HB5385

Establishes statutory speed limits based on road characteristics: 15 mph in mobile home parks, 25 mph in business districts/parks/residential subdivisions, and 25-45 mph on local streets based on vehicular access point density (60+ points = 25 mph; 30-39 points = 45 mph).

Creates a temporary provision allowing 25 mph speed limits on local residential streets until January 1, 2023, while the Department of State Police conducts a speed study to be reported by January 1, 2022.

Requires speed limits to be posted and enforced through traffic control orders filed with appropriate county, city, or village clerks; absence of proper posting defaults to the basic speed law.

Mandates that by September 1, 2019, all limited access freeways be posted at 75 mph and all state trunk line highways outside incorporated cities/villages be posted at 65 mph, unless engineering and safety studies support different limits.

Requires the state transportation department and department of state police to conduct engineering and safety studies to increase speed limits on at least 600 miles of freeways to 75 mph and 900 miles of trunk line highways to 65 mph where conditions permit.
