South Dakota DMV Permit Practice Test

The South Dakota knowledge test is the gateway between you and an instruction permit. The test is based on the South Dakota Driver License Manual.

• ✓
  Under-18 examPass with a score of 80% or higher. Waived if you present a certificate from an approved driver education course completed within the last year.
• ✓
  Adult examPass with a score of 80% or higher. Same passing bar as the teen test.
• ✓
  Application fee$38 for both the Instruction Permit and the Restricted Minor's Permit. In person, DPS takes cash, check, money order, and credit or debit cards (a card fee applies).
• ✓
  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. 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.

  What to watch for in SDThe South Dakota Driver License Manual covers a wide range: sign shapes, right-of-way, BAC rules, hill-parking wheel direction, and specific GDL restrictions. The handbook covers traffic laws and safety in detail.

The handbook covers traffic laws and safety in detail. Road signs matter too. Know the rules before you learn the signs.

• ✓
  Traffic lawsRight-of-way at intersections, turning, passing, lane changes, and speed rules.
• ✓
  SafetyHazardous conditions, following distance, emergency vehicles, fatigue, and defensive driving.
• ✓
  Road signsSign 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. 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.
• ✓
  Turn signal distanceSignal at least 100 feet before any turn. Always signal before reaching the intersection, not after you're already committed.
• ✓
  BAC limit (21 and older)0.08% or higher is a DUI. Impairment can begin below the legal limit.
• ✓
  Under-21 BAC ruleUnder 21, it is illegal in South Dakota to drive with a BAC of 0.02% or higher, far below the 0.08% adult limit.
• ✓
  Chemical test refusalRefusing a law enforcement alcohol analysis test results in automatic license suspension. 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. A cyclist may legally occupy the left lane when making a left turn. Expect them and share the road.

These topics are easy to mix up. If you only have time to review a few, review these.

• ✓
  Four-way stop tie-breakers'First to arrive goes first' is the easy part. The tie rule is the one to remember: when two cars arrive simultaneously, yield to the driver on your right — meaning you go first if the tie is to your left.
• ✓
  School bus — stop in both directions (on two-lane roads)When a stopped school bus has its red lights flashing, you must stop and stay stopped until the red lights go off. On a road with fewer than two lanes in each direction, drivers coming from BOTH directions have to stop. On a highway with two or more lanes in each direction, oncoming traffic does not have to stop, but traffic going the same way as the bus always does. The Driver License Manual words the exception as a physical barrier between roadways.
• ✓
  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.
• ✓
  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. 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. Know that you can be impaired and still be under the legal limit.
• ✓
  'Always' and 'never' wordingBe careful with absolute wording — but some rules are genuinely absolute, such as always yielding to pedestrians in a crosswalk. Read every option before picking.
• ✓
  Passing rulesPass only when the line beside your lane is broken. Driving off the pavement to get around another vehicle is never legal in South Dakota, under any circumstance. You may move back into your lane only once both headlights of the vehicle you passed show in your rearview mirror.

Reading the handbook once may not be enough. Here is a simple three-loop routine: 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 pulls the key points 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.
• ✓
  Loop 3 — listen along on YouTubePlay our South Dakota Road Signs or Traffic Laws video the day or two before your test. It makes a useful last review.
• ✓
  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 — a sign on the road won't come with a label.
• ✓
  Read every option before pickingThe first option can look 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 includes a long permit phase, a mandatory inclement-weather driving requirement, and a 10 PM–6 AM night curfew on the Restricted Minor's Permit.

• ✓
  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.
• ✓
  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).
• ✓
  Restricted Minor's Permit — night curfewNo driving between 10:00 PM and 6:00 AM unless a parent or legal guardian is seated beside you. You may drive alone after 10 PM only on the most direct route to or from school or a school event, church or a church event, or work (or farm-related work). The 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: no more than one passenger under 18 who is not immediate family or a household member.
• ✓
  When restrictions liftYou must hold the Restricted Minor's Permit for at least 6 months AND be at least 16 years old AND have no traffic convictions in the previous 6 months. All three conditions must be met before you can upgrade to a full Operator's License.
