SDCL § 32-20B-7: Racing in approved event authorized--Approval of Transportation Commission or local authorities.

A person may race a bicycle on a highway when competing in a racing event that has been approved by the Transportation Commission or local authorities on a highway under their jurisdictions. Approval of a bicycle highway racing event may be granted only under conditions that assure reasonable safety for all race participants, spectators, and other highway users, and prevent unreasonable interference with traffic flow, which would seriously inconvenience other highway users. Tests of endurance are not considered bicycle racing.
