This bill amends South Dakota law regarding the weight limits for vehicles equipped with pneumatic tires, specifically focusing on mobile cranes. It establishes a new weight limit of six hundred fifty pounds per inch of tire width for mobile cranes operating on highways, provided they have a permit issued under existing regulations. Additionally, the bill clarifies that other types of axles have different weight limits, including six hundred pounds per inch for certain dual tire axles and five hundred pounds for other axle types. The previous weight limit designation for one of the categories has been deleted and replaced with a new classification.

Furthermore, the bill introduces a definition for "mobile crane," describing it as a lifting machine mounted on a self-propelled carrier with a telescoping or lattice boom, designed for easy mobility between work sites for lifting heavy materials. This legislative change aims to accommodate the operational needs of mobile cranes while ensuring compliance with safety regulations on state highways. Violations of these weight limits are classified as a Class 2 misdemeanor.
