The bill amends the Michigan Vehicle Code, specifically section 722, to establish new maximum axle load limits based on the distance between axles for vehicles with high-pressure pneumatic or balloon tires. The new limits are set 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, allowing a maximum tandem axle assembly loading of 16,000 pounds per axle under certain conditions. Additionally, the bill outlines exceptions to seasonal weight restrictions for vehicles transporting agricultural commodities and public utility vehicles, permitting them to exceed standard loading limits with proper permits.

Moreover, the bill proposes amendments to existing vehicle weight regulations, maintaining a gross vehicle weight limit of 80,000 pounds while allowing for increased axle loading maximums by 10% for vehicles transporting agricultural commodities or raw timber. It specifies that these increased limits do not apply to vehicles using interstate highways or roads with seasonal weight restrictions. Vehicles powered by compressed or liquefied natural gas or electric batteries with a gross weight of 82,000 pounds or less may exceed axle loading and weight load maximums by up to 2,000 pounds. The bill also includes definitions for terms such as "agricultural commodities" and "public utility vehicle" to clarify its scope, aiming to facilitate the transportation of agricultural products and promote alternative fuel vehicles while ensuring compliance with safety regulations.
