The bill amends the Michigan Vehicle Code, specifically section 628, to provide clearer guidelines for establishing speed limits on county highways. It allows the county road commission, township board, and the department of state police to set maximum or minimum speed limits based on engineering and traffic investigations, with the requirement that they act unanimously. The bill introduces a new provision that permits counties, townships, cities, or villages to determine and enforce modified speed limits within their jurisdictions, provided they obtain prior written approval from the local law enforcement agency and hold a public hearing to gather community input.

Additionally, the bill specifies that modified speed limits must be in multiples of 5 miles per hour and considers various factors such as public safety, community character, and traffic flow efficiency. It also mandates that any objections from law enforcement regarding safety concerns must be addressed before implementing the modified speed limit. The state transportation department is tasked with developing best practices for traffic studies and providing technical assistance to local authorities in setting these limits. Overall, the bill aims to enhance road safety while allowing local jurisdictions more flexibility in managing speed limits.
