The bill amends South Dakota law to establish a greater tire weight limit specifically for mobile cranes operating on highways. Under the revised statute, the weight limit for a mobile crane with a boom carried over the vehicle is increased to six hundred fifty pounds per inch of tire width on any axle permanently attached to the crane, provided it operates under a permit. This change aims to accommodate the unique operational needs of mobile cranes, which are designed for lifting and moving heavy materials across various work sites.

Additionally, the bill maintains existing weight limits for other types of axles, including those equipped with dual tires, steering axles, and axles of oversize or overweight vehicles, while ensuring that no axle or combination of axles exceeds the maximum weight limits specified in another section of the law. The violation of these weight limits remains classified as a Class 2 misdemeanor. The definition of a "mobile crane" is also included to clarify the type of vehicle affected by this legislation.
