The bill amends the Michigan Vehicle Code, specifically section 722, to establish new maximum axle load limits for vehicles equipped with high-pressure pneumatic or balloon tires, based on the distance between axles. The new limits set the maximum axle load at 18,000 pounds for axles spaced 9 feet or more apart, 13,000 pounds for axles spaced between 3.5 and 9 feet, and 9,000 pounds for axles spaced less than 3.5 feet apart. It also introduces provisions for designated highways where heavier loading may be permitted under certain conditions, including a maximum tandem axle assembly load of 16,000 pounds if there is no other axle within 9 feet. Additionally, the bill outlines exceptions to seasonal weight restrictions for vehicles transporting agricultural commodities and public utility vehicles, allowing county road commissions to issue permits detailing routes and conditions for travel.

Moreover, the bill proposes amendments to existing vehicle weight regulations by allowing increased axle loading maximums by 10% for vehicles transporting agricultural commodities or raw timber, while maintaining overall gross vehicle weight restrictions. It specifies that these increased maximums do not apply to vehicles using interstate highways or those subject to seasonal weight restrictions. Vehicles with a gross weight of 82,000 pounds or less that are powered by compressed or liquefied natural gas or electric batteries may exceed axle loading maximums by up to 2,000 pounds. The bill also defines key terms related to agricultural commodities, emergency public utility work, and public utility vehicles, ensuring clarity on the types of vehicles and loads subject to the new regulations while addressing the needs of the agricultural sector and maintaining road safety.
