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 5029: Highways: bridges; movable bridge fund; modify. Amends sec. 11g of 1951 PA 51 (MCL 247.661g).

HB 5029 modifies Michigan's Movable Bridge Fund to clarify how funds are distributed for the operation of publicly owned movable bridges (like drawbridges). It requires bridge owners and operators to submit annual operational cost data, which the state transportation department uses to calculate fund distributions based on estimated costs. The fund, which retains unused money year-to-year, may also cover required federal bridge inspections or analyses if no other funding exists - until December 2030. Operational costs covered include routine operation expenses (e.g., staffing), but exclude maintenance, repairs, or capital improvements.

HB 4522: Traffic control: traffic regulation; requirement to drive in the right-hand lane of a roadway with 2 lanes for travel in 1 direction; modify. Amends sec. 634 of 1949 PA 300 (MCL 257.634).

HB 4522 modifies Michigan's vehicle code to require heavy trucks (over 10,000 pounds gross weight) to drive in any lane on freeways with three or more lanes for travel in the same direction, rather than restricting them to the rightmost lanes. This directly affects commercial truck drivers and fleet operators on Michigan freeways. The law specifies exceptions allowing trucks to use the right lane only for left turns, safety reasons, or construction-related lane closures. It also prohibits local governments from creating conflicting lane-use ordinances for these situations.

SB 235: Corporate income tax: credits; credit for use of sustainable aviation fuel; provide for. Amends 1967 PA 281 (MCL 206.1 - 206.847) by adding sec. 678. TIE BAR WITH: SB 236'25

SB 235 creates a corporate income tax credit for businesses that use sustainable aviation fuel (SAF). It directly affects airlines and fuel producers in Michigan by reducing their state tax liability based on the volume of SAF they utilize. The bill amends Michigan's tax code (MCL 206.1-206.847) to add a specific provision allowing corporations to claim this credit. This provides a financial incentive for adopting SAF, aiming to support cleaner aviation fuel adoption without specifying environmental outcomes.

HB 4470: Highways: bridges; Mackinac Bridge; designate as a key facility. Amends sec. 552c of 1931 PA 328 (MCL 750.552c).

HB 4470 amends Michigan's penal code to designate specific portions of the Mackinac Bridge (those not open to or intended for public use) as a "key facility" under existing law. This means unauthorized entry onto these bridge sections - when enclosed by barriers like water and properly posted with signage - would become a felony punishable by up to 4 years in prison or a $2,500 fine. The bill adds the Mackinac Bridge to a list of protected critical infrastructure, including power plants, water facilities, and chemical plants, all requiring physical barriers and visible signage to enforce entry restrictions. It does not change current penalties or posting requirements but extends them specifically to the Mackinac Bridge's restricted areas.

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.

HB 5156: Traffic control: traffic regulation; authority to provide road closures in the interest of public safety; expand. Amends 1949 PA 300 (MCL 257.1 - 257.923) by adding sec. 606c.

HB 5156 amends Michigan's Vehicle Code to give local law enforcement agencies (like city police or county sheriffs) temporary authority to control traffic during emergencies or specific events. It allows officers or temporary devices to guide, direct, or stop traffic on any public road within their jurisdiction when necessary for public safety, including during large marches, parades, protests, terrorist attacks, or violent acts. The bill specifically expands existing traffic control powers to cover these scenarios without requiring prior court orders. This change directly affects how local police manage traffic during public gatherings or crises, aiming to enhance safety responses. The bill is currently in committee review after being introduced on October 29, 2025.

SB 646 amends Michigan's Infrastructure Council Act to restructure how the state manages public infrastructure assets. It requires the council to develop annual asset management plans, a 3-year strategy for a statewide integrated system, and annual reports tracking progress toward performance goals. Key provisions mandate consistent data standards, regional coordination for infrastructure planning, and specific requirements for transportation, water, and other asset systems. The bill directly affects state agencies, local governments, and regional planning bodies responsible for infrastructure maintenance and reporting. It also prohibits government-owned broadband networks (except for transportation uses) and restricts broadband subsidies to unserved areas with competitive bidding.

HB 5175 requires that for new highway construction or full bridge reconstruction starting January 2026, contractors must provide a 10-year maintenance contract covering design, building, operation, and upkeep of the project. This applies to state and local road agencies, making contractors responsible for repairs (like potholes or snow removal) for a decade or until the first major preventative maintenance, whichever comes later. The bill specifies that contractors aren’t liable for disaster damage (e.g., floods or storms), and annual payments must remain at least 10% of peak annual payments. It directly affects road construction projects, contractors, and taxpayers by shifting long-term maintenance responsibility to private entities.
