South Dakota Driver's License Manual (rev. 11/2024, South Dakota Department of Public Safety), PDF fetched directly from https://www.sd.gov/sys_attachment.do?sys_id=d8e0b08e47bd0390a497127ba26d4348 (served as driver-license-manual-2025-english.pdf; it is the "Driver's License Manual - English" link on the DPS "South Dakota Driver License and Motorcycle Manuals" article at https://www.sd.gov/dps?id=kb_article_view&sysparm_article=KB0043733), and South Dakota Codified Laws Title 32 via the official Legislature site at https://sdlegislature.gov (individual sections fetched as https://sdlegislature.gov/Statutes/{section}, machine-readable at https://sdlegislature.gov/api/Statutes/Statute/{section}) — specific sections used: 32-25-28 (passing-speed allowance), 32-24-1 (reckless driving) and 32-24-8 (careless driving), 32-28-4 (right turn on red) and 32-28-4.1 (left turn on red, local option) and 32-28-8.2 (malfunctioning signal), 32-38-3 (seatbelt) and 32-12-49.1 (seatbelt violation not a moving offense), 32-26-47.1 (handheld device ban) and 32-26-47.2 (social media ban), 32-31-6.1 (move-over law), 32-26-13/-14/-19 (right-of-way) and 32-27-7 (blind pedestrian full-stop requirement), 32-30-6 and related parking sections, 32-26-26.1 (bicycle passing clearance), and 32-37-1/-1.1/-1.2/-1.3 (child passenger safety) — researched and verified 2026-08-19, citation gap closed 2026-08-20. VERIFICATION NOTES 2026-08-20: DPS has migrated off its old site — every legacy dps.sd.gov path (including the previously-circulated /application/files/.../sd-driver-manual-rev-12-2023.pdf and /driver-licensing/... URLs) now 302-redirects to a JavaScript-rendered ServiceNow portal at www.sd.gov/dps that serves no document links to a plain fetch. The manual was therefore retrieved through the portal's server-rendered article view (https://www.sd.gov/kb_view.do?sysparm_article=KB0043733), which exposes the real attachment URL cited above; the downloaded PDF text-extracts cleanly and its final page reads "REVISED 11/2024", independently confirming this module's stated edition. SDCL sections were confirmed live the same way — 32-24-1 returns "Definition of reckless driving--Misdemeanor", 32-31-6.1 "Occupying highway shoulder or stopped--Requirements for approaching vehicles--Penalty", 32-26-47.1 "Use of mobile electronic device--Prohibitions", 32-25-28 "Exceeding posted speed limit permitted under certain conditions", 32-28-4 "Meaning of steady red light or stop signal--Vehicular traffic--Right turn on red", and 32-37-1 "Use of system required--Violation as petty offense". Mock exam config is PART-CONFIRMED, PART-ESTIMATE, and the split matters: the 80% pass threshold (rulePassPct: 0.8) IS now officially sourced — DPS's own "South Dakota Driver License Testing Information" article (https://www.sd.gov/dps?id=kb_article_view&sysparm_article=KB0043731, read via https://www.sd.gov/kb_view.do?sysparm_article=KB0043731) lists among the license requirements: "Pass a knowledge test with a score of 80% or higher. This test will cover rules of the road and safe-driving practices." CORRECTION to the prior note, which claimed the only published 80% figure was the driver's-education evaluation used for the 275-to-180-day permit reduction: that driver-ed 80% does exist (it is in the manual's Instruction Permit section) but it is a SEPARATE figure, and DPS does additionally publish 80% for the knowledge test itself. The question COUNT remains genuinely unpublished — the manual states no count (searched for "question", "pass", "score") and the testing article says outright "There is no sample test" / "We do not provide pre-tests or sample tests" — so ruleCount: 30 stays a flagged ESTIMATE sized consistently with other unified-format states in this app. signCount: 0/signPassCount: 0 follows from the testing article describing one knowledge test with no separate sign-recognition gate. Deliberately NOT invented, and explicitly flagged as gaps: the exact SDCL citation for the school-bus stop-arm law (sourced only to the Driver's License Manual's general description); any specific booster-seat age/height bracket (South Dakota has no dedicated booster statute — a genuine, confirmed gap versus many other states, not an oversight); and any specific statutory rear-facing age/weight requirement (the manual gives only general, non-statutory safety guidance — 'never place a rear-facing seat in front of an active airbag,' 'use an infant carrier until about 9 months' — not a legal age/weight cutoff). No genuine South Dakota-specific sign (MUTCD) deviations were found, so signsExtra/rowExtra are omitted and shared federal sign/right-of-way content is reused as-is aside from the blind-pedestrian full-stop rule folded into the rightofway category. Re-verify periodically, as DMV/DPS manual content, fees, and thresholds change over time.
