S.D. Codified Laws § 32-22-57 (2026)
Unless specifically authorized by permit, a variable load axle may not be raised if, when it is raised, it causes any other axle to be overloaded. The transportation commission may promulgate rules, pursuant to chapter 1-26, to provide for the issuance of annual permits by the Division of Highway Patrol which authorize the raising of a variable load axle while turning. The annual permit is not valid on the interstate system. A violation of this section subjects the violator to a civil penalty of five hundred dollars for each violation.
