S.D. Codified Laws § 31-4-14.6 (2026)
The Department of Transportation shall post signs on a minimum maintenance segment of road to notify motor vehicle drivers that it is a minimum maintenance segment and that travel on the road is at the driver's own risk. The signs shall be posted at the entry points to and at regular intervals along a minimum maintenance segment. A properly posted sign is prima facie evidence that adequate notice of a minimum maintenance has been given to the motor vehicle driver.
