This bill allocates state funds to the Michigan Transportation Department for the 2025-2026 fiscal year (ending September 30, 2026). It provides the necessary budget authority for the department to operate and maintain state transportation infrastructure during that period. As a routine appropriations measure, it does not create new policies or directly affect residents or businesses beyond funding existing transportation programs. The bill's sole purpose is to authorize spending for the department's ongoing operations.
HB 4597 amends Michigan's Vehicle Code to allow local governments (counties, townships, cities, and villages) to set or change speed limits on local highways without requiring a traffic engineering study. Instead, local authorities must first obtain written approval from the chief law enforcement officer (or county sheriff if none exists) and hold a public hearing with at least 14 days' notice. Speed limits established under this bill must be in 5 mph increments and consider factors like public safety, community input, road features, and environmental concerns. This change streamlines local speed limit adjustments while maintaining oversight through law enforcement approval and public engagement.
SB 365 amends Michigan's vehicle code to allow motorcycles to filter between lanes when traffic is stopped or moving slowly (under 10 mph), under specific safety conditions. The law requires at least two lanes in the same direction, motorcycle speed under 15 mph, and confirmation that the maneuver is safe. This directly affects motorcycle riders who may use this technique in congested traffic and other drivers who must share the road. The change applies only to motorcycles and does not alter existing rules for mopeds, electric skateboards, or other vehicles.
HB 4656 prohibits highway officials from completely shutting down all lanes of a road during construction if it would cut off a community’s only access point or if the only alternative route is frequently blocked by railroad crossings. The bill amends Michigan law to require that such closures only occur when absolutely necessary for construction, and even then, must be temporary with work completed expediently to reopen at least partial access as soon as possible. It directly affects communities relying on single road access and highway officials managing construction projects. The key provision prevents full closures that isolate communities, while allowing temporary full shutdowns only when no feasible alternative exists for maintaining traffic flow.
HB 4426 amends Michigan's Motor Carrier Safety Act (MCL 480.12d) to set a minimum age of 21 for drivers transporting hazardous materials requiring placards under federal rules. It maintains the existing 18-year-old minimum for most commercial driving but specifically raises the age requirement for hazardous materials transport. The bill does not change medical waiver or grandfathered driver provisions. This change directly affects commercial drivers operating in Michigan who transport hazardous materials requiring placards.
SB 448 creates a state-funded road investment incentive program that provides dollar-for-dollar matching grants to local road agencies (like counties and cities) for road construction, maintenance, or repair projects. Local agencies must contribute non-federal, non-state funds to match the grants, and total statewide grants are capped at 1 mill of all taxable property value in Michigan. The program requires local agencies to annually verify the sources of their matching funds, and the state transportation department must establish and publish clear application and award criteria online. This bill directly affects local governments managing public roads by providing new funding flexibility while ensuring local investment.
HB 4735 requires operators of heavy vehicles (59,999 pounds or more) to report quarterly miles driven in Michigan and pay a $0.0285 per mile "weight-distance fee" starting January 1, 2027. It allows for a $40, 10-day unlimited-mile pass to temporarily avoid reporting and fees. Penalties include fines for missed reports (2% of estimated fee or $100 min), misreporting (50% of fee), and late payments (2% per 30 days, with interest). The bill directly affects commercial trucking operators and owners of large vehicles operating on Michigan public highways.
SB 467 amends Michigan's school transportation law to update safety requirements for school buses and establish new rules for schools contracting with public transit agencies to transport students. It requires all school buses to meet federal safety standards and prohibits using non-school buses with 11+ seats for student transport (except special cases). For public transit contracts, the bill mandates written agreements covering driver background checks, strict safety protocols (like activating amber lights 200 feet before stops), route safety, and mandatory vehicle inspections before use. These provisions directly affect schools, public transit agencies, and students by setting clear safety standards for alternative transportation options.
HB 4415 requires county road commissions to use competitive bidding for certain road projects that were previously exempt. This bill directly affects county road commissions by modifying existing rules (MCL 224.10) to expand the requirement for public bidding on specific infrastructure work. The key provision mandates that counties must solicit competitive bids for projects like road construction or repairs that meet defined criteria, ensuring transparency in spending. This change applies to all counties in Michigan where such projects were previously handled without competitive processes.
HB 4875 mandates annual state funding of at least $125 million starting in fiscal year 2026 to cover school transportation costs for students. It directly affects Michigan public school districts by requiring dedicated state appropriations for pupil transportation, as defined under existing state school aid law. The bill creates a permanent funding mechanism ensuring consistent support for school bus services and related operational costs. This provision applies specifically to transportation services for students, not general school funding. The bill is currently under review in the Appropriations Committee after its introduction on September 11, 2025.
