HB 4721 creates tax credits for biodiesel sales and production in Michigan, effective 2025-2030. Retail fuel dealers receive credits of $0.02-$0.07 per gallon for selling biodiesel blends (6-9%, 10-19%, or 20%+), while biodiesel producers get $0.02 per gallon. Total credits are capped at $16 million annually for retailers and $2 million for producers, with excess claims distributed proportionally. The bill directly affects Michigan fuel retailers and biodiesel producers by reducing their income tax liability based on specific blend volumes sold or produced.
HB 4084 creates a state program to fund sound walls and other noise-reduction measures along Michigan's state trunk line highways where no such barriers currently exist. It directs the Michigan Department of Transportation (MDOT) to provide grants or loans to local road authorities for constructing or maintaining these noise barriers. The program uses a scoring system prioritizing cost-effectiveness, noise reduction for residential areas (minimum 5 decibels), existing noise levels, and benefits to schools/parks. MDOT must publicly report annual applications, approvals, and project outcomes to legislative committees.
HB 4722 creates tax credits to incentivize biodiesel use in Michigan. Retail fuel dealers selling biodiesel blends (6-9% at $0.02/gal, 10-19% at $0.05/gal, 20%+ at $0.07/gal) can claim credits, while biodiesel producers get $0.02 per gallon produced. Credits apply for tax years 2025-2030, with a $16 million total cap for retailers and a $2 million cap for producers. This directly affects Michigan fuel retailers and biodiesel manufacturers by reducing their income tax liability for qualifying sales and production.
SB 217 increases penalties for drivers who commit moving violations (like speeding or reckless driving) that cause physical injury or death to pedestrians, cyclists, or other vulnerable roadway users. It amends Michigan's criminal code (MCL 777.12e) to enhance the penalties for these specific offenses. The bill directly affects drivers whose actions result in harm to non-motorized road users, raising the legal consequences for such incidents.
SB 216 increases criminal penalties for drivers who cause physical injury or death to pedestrians, cyclists, or other vulnerable roadway users through moving traffic violations (like speeding or running a red light). It amends Michigan's traffic laws to enhance penalties under specific sections, adding new provisions (79g and 79h) that strengthen consequences for these offenses. The bill directly affects drivers convicted of moving violations resulting in harm to non-motorized road users, making penalties more severe than current standards. This policy change focuses on improving accountability for dangerous driving that endangers pedestrians and cyclists, without specifying future outcomes.
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 4349 allows Michigan cities to contract with private companies for the maintenance or improvement of private roads within their boundaries. This change directly affects cities seeking to partner with outside contractors for road work on privately owned streets, removing a prior restriction. The bill amends the Municipal Home Rule Act (MCL 117.1-117.38) by adding Section 5l, granting cities this new authority. The legislation passed unanimously in the House with immediate effect on September 17, 2025.
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 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 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.
