SDCL § 32-22-60: Size and load restrictions--Notice--Violation as misdemeanor.

If for any reason a segment of the state trunk highway system cannot accommodate the motor vehicle size limits set forth in chapter 32-22 without endangering public safety or damaging the highway surface or structures, the transportation commission may adopt rules, pursuant to chapter 1-26, to restrict the size of a vehicle and its load over that highway segment. Notice of any restriction under this section shall be given by placing at the beginning and end and points of intersection signs of substantial construction which conspicuously indicate the vehicle size limitation. A violation of this section is a Class 2 misdemeanor.
