South Dakota DMV Permit Practice Test

The South Dakota knowledge test is the gateway between you and an instruction permit. Your questions come from the South Dakota Driver License Manual, and SD DPS will not tell you which ones you missed if you fail — you only get the final score.

• ✓
  Under-18 exam25 questions. Pass at 20 correct (80%). Waived entirely if you completed an approved driver education course.
• ✓
  Adult exam25 questions. Pass at 20 correct (80%). Same format and passing bar as the teen test.
• ✓
  Application fee$28 for both the Instruction Permit and the Restricted Minor's Permit. Bring cash or a check — not all DPS offices take cards.
• ✓
  Bring with youProof of identity (birth certificate or passport), proof of South Dakota residency, and your Social Security number or proof of Social Security number.
• ✓
  Driver ed starts at 14South Dakota allows driver education at age 14 — earlier than most states. Completing 30 hours of classroom instruction plus 6 hours of behind-the-wheel training cuts your instruction permit hold time from 275 days to 180 days.

  Why SD catches first-timers off guardThe South Dakota Driver License Manual is concise but tests a wide range: sign shapes, right-of-way, BAC rules, hill-parking wheel direction, and specific GDL restrictions. Traffic laws and safety questions together make up over 70% of the bank.

South Dakota's question bank leans heavily on traffic laws and safety — those two categories make up 71% of the 441 questions. Road signs come third. Know the rules before you learn the signs.

• ✓
  Traffic laws (~36% of the bank — 159 questions)Right-of-way at intersections, turning, passing, lane changes, and speed rules. The single largest category.
• ✓
  Safety (~34% — 152 questions)Hazardous conditions, following distance, emergency vehicles, fatigue, and defensive driving. Nearly ties traffic laws for top billing.
• ✓
  Road signs (~16% — 71 questions)Sign shapes, colors, and meanings. A flashing red light is treated like a stop sign. Pay close attention to orange work-zone diamond signs.
• ✓
  Right-of-way at four-way stopsFirst to arrive goes first (Q22044). If you and the driver on your left arrive at the same time, you have the right-of-way — yield to the right applies when it's a tie (Q22143).
• ✓
  Turn signal distanceSignal at least 100 feet before any turn (Q22111). Always signal before reaching the intersection, not after you're already committed.
• ✓
  BAC limit (21 and older)0.08% or higher is a DUI (Q22255). A BAC of just 0.02% already nearly doubles your crash risk — impairment starts well below the legal limit (Q22126).
• ✓
  Under-21 BAC ruleZero tolerance — ANY detectable amount of alcohol suspends your license (Q22153). Don't pick a numeric answer on the test; the correct answer is "any amount."
• ✓
  Chemical test refusalRefusing a law enforcement alcohol analysis test results in automatic license suspension (Q21969). Refusing is not a legal shield — implied consent applies the moment you drive in South Dakota.
• ✓
  Bicycles as vehiclesBicycles are legally vehicles on South Dakota roadways (Q22117). A cyclist may legally occupy the left lane when making a left turn (Q22149). Expect them and share the road.

These are the categories that sink more first-time South Dakota test-takers than any other. If you only have time to drill a few, drill these.

• ✓
  Four-way stop tie-breakersMost people know 'first to arrive goes first.' Almost no one recalls the tie rule correctly: when two cars arrive simultaneously, yield to the driver on your right — meaning you go first if the tie is to your left (Q22143).
• ✓
  School bus — stop in both directionsWhen a school bus is stopped with red lights flashing and the stop arm extended, traffic in BOTH directions must stop and remain stopped until the lights stop flashing (Q21882, Q21885). The exception only applies if a physical median separates the roadway.
• ✓
  Hill parking — downhill (with or without curb)Turn your front wheels toward the right side of the road (toward the curb or edge). If the brake fails, the car rolls into the curb or road shoulder, not into traffic (Q22019, Q22202).
• ✓
  Hill parking — uphill with a curbTurn your front wheels AWAY from the curb. The curb itself acts as the stopper if the car rolls back (Q22273). Always set the parking brake and leave the car in Park regardless of direction.
• ✓
  Impairment vs. the legal limit0.08% is the legal BAC threshold, not the safety threshold. Every 0.02% increase roughly doubles your crash risk (Q22126). The test asks the difference — know that you can be impaired and still be under the legal limit.
• ✓
  'Always' and 'never' answer optionsGenerally wrong — unless the topic is genuinely absolute (e.g., always yield to pedestrians in a crosswalk at all times, Q21956). Read every option before picking.
• ✓
  Passing rulesOnly pass on a road with a broken line next to your lane (Q21939). Never pass by driving off the road — there is no circumstance where this is legal in South Dakota (Q21979). Before returning to your lane, both headlights of the passed vehicle must be visible in your rearview mirror (Q21957).

Reading alone reliably tops out around 60% on the real test. The students who pass first try use three loops: read once, drill once, listen once. That's it.

• ✓
  Loop 1 — read the handbookDownload the South Dakota Driver License Manual free from dps.sd.gov. Read it once — don't try to memorize. This guide compresses the highest-yield 20% into bullets you can scan in 10 minutes.
• ✓
  Loop 2 — drill the practice examsTake the free 40-Q exam below cold. Anything under 32/40 — focus on the categories you missed and retake. We have 11 distinct exams (441 questions total) for South Dakota. Traffic laws and safety are your biggest ROI.
• ✓
  Loop 3 — listen along on YouTubePlay our South Dakota Road Signs or Traffic Laws video the day or two before your test. Hearing the questions out loud locks them in faster than re-reading.
• ✓
  Sleep beats crammingMemory consolidates overnight. A full sleep the night before is worth more than two extra hours of late-night reading.
• ✓
  Study signs visuallyNever read sign descriptions in text only. Look at the actual shape and color. The test shows you the sign image, not the words.
• ✓
  Read every option before pickingSD DPS writes plausible wrong answers. Most exam questions have 3 options (A/B/C), but the first option often looks right until you read the others and find a more precise answer.

Passing the knowledge test gets you an Instruction Permit — not a full license. South Dakota's GDL program is stricter than most: a long permit phase, a mandatory inclement-weather driving requirement, and night curfews that run until age 18.

• ✓
  Supervision during the permit phaseA licensed adult must be seated in the front passenger seat whenever you drive on an Instruction Permit. No solo driving — ever, on a permit.
• ✓
  Permit hold time275 days minimum without driver education. Completing an approved driver ed course shortens this to 180 days. Either way, this is one of the longest hold requirements in the country.
• ✓
  50 hours of supervised practiceAt least 50 total hours behind the wheel with a licensed adult supervisor — including at least 10 hours at night and at least 10 hours in inclement weather (rain, snow, ice, or fog). The inclement-weather requirement is unique to South Dakota.
• ✓
  Restricted Minor's Permit — night curfewNo driving between 10:00 PM and 6:00 AM unless a licensed parent or legal guardian is in the front seat. Curfew applies throughout the restricted permit phase.
• ✓
  Passenger restrictionsFor the first 6 months on a Restricted Minor's Permit: passengers limited to immediate family and household members only. After 6 months: one non-family passenger is allowed.
• ✓
  When restrictions liftYou must hold the Restricted Minor's Permit for at least 6 months AND reach age 18 AND have no traffic violations in the previous 6 months. All three conditions must be met before you can apply for a full license.
