Sample South Dakota permit test questions
Here are a few real questions from our South Dakota bank, with the correct answer and a plain-language explanation. The full test has many more.
- Pavement MarkingsEasy
1. A single broken (dashed) white line between lanes going the same direction means:
- You may never change lanes
- You may change lanes when it is safe
- Traffic flows in opposite directions
- The lane is for buses only
Why: Broken white lines separate same-direction lanes and allow lane changes when safe.
- Road SignsMedium
2. A black-and-white sign reading 'Do Not Pass' or showing a no-passing symbol means:
- You may pass only large trucks
- Passing is allowed on the right only
- You may not pass other vehicles in that zone
- The road ends ahead
Why: A no-passing-zone sign prohibits overtaking because of limited sight distance or other hazards.
- EmergenciesHard
3. If your vehicle's brakes suddenly fail, you should:
- Turn off the engine immediately
- Steer into oncoming traffic
- Close your eyes and brace
- Pump the brakes, downshift, and use the parking brake gradually
Why: Pump the brakes, shift to a lower gear, and apply the parking brake gradually while steering to safety.
- Traffic LawsEasy
4. Seat belts in a moving vehicle should be worn by:
- The driver and all passengers
- The driver only
- Front-seat occupants only
- Only on highways
Why: Buckling up is required for the driver and passengers and is the single best protection in a crash.
What’s on the South Dakota test
Our South Dakota question bank is balanced across the categories the DPS tests. These are the topics to study:
How the South Dakota written test works
The South Dakota permit knowledge test contains 25 questions drawn from the official driver manual. To pass, you need to answer at least 20 of them correctly, which works out to a 80 percent score. The questions are multiple choice, and each one has a single best answer.
Most questions focus on the meaning of signs and signals, who has the right-of-way in common situations, and how to react safely to hazards. There are no trick questions, but the wording can be precise, so read each option carefully before choosing. If you do not pass on your first attempt, you can study and try again after the waiting period set by your local office.
What to study
Focus your study time on the topics that appear most often and that new drivers most commonly get wrong. The categories below cover the bulk of the South Dakota exam.
- Road signs by shape and color: stop, yield, no-passing, speed-limit, pedestrian, railroad, and school-zone signs.
- Traffic signals including steady and flashing red, steady and flashing yellow, and green and red arrows.
- Right-of-way rules at four-way stops, uncontrolled intersections, roundabouts, and crosswalks.
- Pavement markings such as solid and broken yellow lines, white lane lines, crosswalks, and stop lines.
- Safe-driving fundamentals like following distance, adjusting for weather, and reacting to emergency vehicles.
Practice Mode vs Exam Mode
Practice Mode shows you the correct answer and a short explanation right after each question, so you learn as you go. Use it early on to build understanding and to find the topics you keep missing. Exam Mode hides the answers until the end and presents the questions the way the real test does, which is the best way to check whether you are ready. A good plan is to use Practice Mode until you are scoring comfortably, then switch to Exam Mode to confirm you can pass under test-like conditions.
South Dakota road conditions to know
South Dakota covers wide-open prairie, long rural highways, and winter weather that can change fast. Review safe driving on ice and snow, the basic speed law that requires slowing below the posted limit when conditions are poor, and how to handle wind on exposed stretches. Watch for wildlife crossing rural roads, especially at dawn and dusk, and for slow-moving farm equipment displaying the orange triangle emblem.
Road signs show up on every test
Learn to read signs by shape and color and you bank easy points. Here are a few you should know cold:
What to study for the South Dakota written test

What happens if you do not pass the South Dakota test?
Missing the cutoff is not the end of the road. The South Dakota written test requires 20 correct answers out of 25 (80%), so you can miss up to 5 questions and still pass. If you score below that line, you are allowed to retake the exam. Most states ask you to wait a short period before trying again, often the same day, the next day, or after a few days, and a small retest fee may apply. The exact waiting period and any fee are set by the South Dakota Driver Licensing Program, so confirm the current policy with them before you return.
The smartest move after a near miss is to study the specific topics that tripped you up rather than starting over from scratch. Our results page shows which categories pulled your score down, so you can focus your next session on road signs, right-of-way, or whichever area needs work. Take the free South Dakota practice test a few more times until you are scoring comfortably above 80%, then schedule your retake with confidence.
