establish a greater tire weight limit for a mobile crane moving on any highway in this state.

HB 1189 increases the maximum allowable weight per inch of tire width for mobile cranes with booms carried over the vehicle from 600 to 650 pounds on South Dakota highways. This change directly affects mobile crane operators transporting equipment on public roads, allowing slightly heavier loads under specific conditions. The bill amends existing weight regulations (§ 32-22-21) to adjust this limit for cranes meeting the defined criteria (self-propelled carriers with telescoping/lattice booms). It does not alter other weight limits or create new requirements, focusing solely on this technical adjustment for crane mobility.
