Offenders facing a first DUI in South Dakota will be subject to both criminal and administrative penalties. Different penalties are applicable to minors in violations of zero tolerance laws, minors whose DUI cases are forwarded to juvenile courts, commercial drivers, and criminal cases involving multiple criminal charges.
Sobriety checkpoints are legal in South Dakota (see 522 N.W.2d 196 (S.D. 1994)). These checkpoints (also referred to as "mobile checkpoints" or "roadblocks") are police traffic stops that are not tied to any specific or individual suspicions.
