HB 4137: Traffic control: speed restrictions; determination in accordance with traffic engineering practices; modify. Amends sec. 628 of 1949 PA 300 (MCL 257.628).

HB 4137 updates Michigan’s speed limit rules to require local governments to set limits based on actual traffic speeds and safety data. It mandates that speed limits be determined using traffic engineering practices, rounded to the nearest 5 mph, and generally align with the 85th percentile speed of free-flowing traffic on a road segment. Exceptions allow lower limits (down to the 50th percentile) only when safety hazards are proven through engineering studies. This directly affects county road commissions, township boards, and city officials responsible for setting speed limits on local roads and highways.

SB 265: Transportation: funds; maintenance of nonmotorized transportation infrastructure; provide for. Amends sec. 10k of 1951 PA 51 (MCL 247.660k).

Senate Bill 265 amends the law governing the Michigan Transportation Fund, affecting how the State Transportation Department, counties, cities, and villages allocate funds. The bill mandates that at least 1% of these funds must be expended on constructing, improving, maintaining, or repairing nonmotorized transportation infrastructure, explicitly stating that "maintaining" does not include snow removal. It broadens the definition of qualified nonmotorized facilities and allows the 1% spending requirement to be met as an average over a 10-year period. Additionally, the bill requires these government entities to develop 5-year programs for nonmotorized facility improvements and consult with other jurisdictions on related projects.

HB 4343: Traffic control: violations; certain trucks assisting in a state of emergency; exempt from frost laws. Amends sec. 722 of 1949 PA 300 (MCL 257.722).

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: Transportation: carriers; limitation on driving hours; remove during a state of emergency. Amends sec. 1a of 1963 PA 181 (MCL 480.11a).

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.

SB 365: Traffic control: traffic regulation; filtering between lanes by a motorcycle; allow under certain conditions. Amends sec. 660 of 1949 PA 300 (MCL 257.660).

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: Transportation: other; road construction projects that shut down all lanes of a road; prohibit. Amends sec. 1 of 1917 PA 165 (MCL 247.291).

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.
