The bill amends Section 628 of the Michigan Vehicle Code to update the procedures for establishing speed limits on county highways, local highways, and other roadways. It allows for a more flexible approach where counties, townships, cities, or villages can determine and enforce modified speed limits within their jurisdictions, provided they obtain prior written approval from the chief law enforcement officer and hold a public hearing to gather community input. The modified speed limits must be in multiples of 5 miles per hour and take into account various factors such as public safety, community character, and traffic flow efficiency.

Additionally, the bill clarifies the roles of different authorities in setting speed limits and mandates that a public record of any traffic control order establishing a modified speed limit be filed with the appropriate county or local office. It also emphasizes the importance of monitoring compliance with safety and engineering standards for any modified speed limits. The state transportation department is tasked with developing best practices for traffic studies and providing technical assistance to local authorities in setting these limits.
