    The statutes that control South Dakota DUI cases

    DUI in South Dakota is defined by S.D. Codified Laws § 32-23-1, and the chemical-testing rules sit in S.D. Codified Laws § 32-23-10. Both are published in the official state code at sdlegislature.gov, which is the only version that governs — summaries elsewhere, including ours, can lag amendments.
