South Dakota Trucking Industry Overview
South Dakota's trucking industry serves agriculture (corn, soybeans, cattle), construction, and energy. Sioux Falls is the state's economic center and primary distribution hub. The state's lack of corporate income tax and personal income tax attracts carriers to domicile here. Several national trucking companies have established South Dakota entities for this reason.
