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.
HB 4214 would have modified Michigan's vehicle code (MCL 257.601b & 257.682) to change the procedures drivers must follow when approaching a school bus displaying yellow flashing lights. The bill directly affected all drivers operating vehicles in Michigan who encounter school buses with yellow lights, which typically indicate the bus is preparing to stop for loading/unloading children. It aimed to adjust the specific actions drivers must take during this phase of bus operation. The bill was defeated in the legislature on June 26, 2025, with a vote of 52-51.
HB 4257 defines key terms related to waste management, specifically for anaerobic digestion byproducts (digestate) and their "beneficial use" in agriculture or construction. It creates five distinct categories of beneficial use (e.g., soil application at agronomic rates, road base, or construction fill) with specific environmental safeguards like runoff prevention and groundwater protection. The bill directly affects waste management facilities, farmers, and construction entities handling digestate or ash by clarifying legal standards for its use. These definitions ensure consistent application under existing environmental rules, requiring materials to meet soil-nutrient balance and pollution prevention criteria.
HB 4203 amends Michigan's Vehicle Code to revise exemptions for tow trucks, wreckers, and road service vehicles from seasonal weight restrictions on state highways. The bill allows these vehicles to operate during restricted periods (typically winter months) when responding to emergencies or providing essential roadside assistance. This change directly affects towing and road service companies by permitting them to operate under weight limits they previously could not during certain seasons. The amendment applies specifically to vehicles performing emergency response or required road service functions.
HB 4343 exempts certain commercial trucks assisting in a declared state of emergency from Michigan's frost laws, which typically restrict truck operations during freezing conditions. This means trucks providing emergency response services (like transporting supplies or personnel) will not face traffic violations for operating during frost conditions when supporting emergency efforts. The bill amends Michigan's Vehicle Code (MCL 257.722) to create this specific exception for emergency assistance vehicles. It directly affects commercial truck operators and emergency management agencies during declared emergencies.
HB 4344 removes driving hour limits for commercial motor vehicle drivers during declared state emergencies. It specifically exempts drivers traveling to assist with or directly helping during disasters from federal hours-of-service rules (49 CFR part 395) under Michigan's Emergency Management Act. This change directly affects commercial drivers transporting goods or people in support of emergency response efforts when a state of emergency is active.
House Resolution 91 is a resolution expressing support for President Trump’s policies aimed at increasing the nation’s energy infrastructure and security. The resolution specifically highlights how these policies have facilitated emergency permitting for the Enbridge Line 5 tunnel project, intended to replace an existing pipeline under the Straits of Mackinac.
HB 4185 changes how Michigan's general sales tax revenue is distributed. It directs 15% of the 4% sales tax to cities, villages, and townships through the Glenn Steil Revenue Sharing Act. Sixty percent goes to the state school aid fund (including all 2% tax from aviation fuel sales), while 27.9% of 25% from vehicle/fuel sales funds the transportation system. Additionally, it requires $9-12 million annually from computer software sales to the Michigan health initiative fund.
HB 4184 increases Michigan's excise tax on aviation fuel from 3.10 cents to 4.00 cents per gallon. It directly affects fuel sellers, airlines, and airport operators by changing how this tax revenue is distributed. The bill modifies Section 203 of the Aeronautics Code to require 35% of the tax revenue to fund the state aeronautics fund and 65% to fund qualified airports. It also retains the 1.5-cent refund for airlines operating interstate flights and the exemption for fuel used in leaded racing fuel production.
HB 4230 creates a new "neighborhood road fund" in Michigan's state treasury, funded by $100 million annually from income tax revenues (specifically from Section 695 of the 1967 Income Tax Act). This fund directly affects county road commissions, city and village road agencies, and the local bridge advisory board. Key provisions require $100 million yearly to be reserved exclusively for repairing closed, restricted, and critical bridges (managed by the advisory board), while the remaining funds are distributed to road agencies based on their road mileage - $100,000 per county commission plus a mileage-based share for all counties, and similarly for cities/villages. The bill specifies these funds must cover road preservation, maintenance, and preventative work without requiring local matching funds.
