SDCL § 31-12-49: Posting of signs along no maintenance highway.

The board of county commissioners shall post signs on a no maintenance highway designated under § 31-12-48 to notify the public that it is a no maintenance highway and that no travel is advised, and that the public travels at its own risk. The signs shall be posted at each entry point and at regular intervals along a no maintenance highway. A properly posted sign is prima facie evidence that adequate notice of a no maintenance highway has been given to the public.
