The bill amends the Michigan Vehicle Code, specifically section 722, to establish new regulations regarding maximum axle loads for vehicles based on axle spacing. It sets 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. The bill also introduces provisions for designated highways where heavier loading may be permitted, including a maximum tandem axle assembly load of 16,000 pounds per axle if there is no other axle within 9 feet. Additionally, it 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.

Furthermore, the bill allows for a 10% increase in axle loading maximums for vehicles transporting agricultural commodities and raw timber, provided they are moving goods from harvest or farm storage to the first delivery point on state roads, excluding interstate highways or roads with seasonal weight restrictions. It also permits vehicles powered by compressed or liquefied natural gas or electric batteries, with a gross weight of 82,000 pounds or less, to exceed axle loading maximums by up to 2,000 pounds. The bill clarifies definitions related to agricultural commodities and public utility work, aiming to facilitate the transportation of agricultural products while ensuring safety and infrastructure integrity.
