Free South Dakota DPS Test Simulator 2026
This DMV Test Simulator is modeled on the Department of Public Safety (Driver Licensing Program) (DPS) written knowledge exam, whose length the agency does not publish; to pass you need 80% correct. It is a mock test: 25 questions (the DPS does not publish the real test length) scored to the 80% pass mark. Answers are marked only when you submit the whole test, then you review every question with its explanation. Every question includes an explanation, so you learn the rule behind each answer - not just whether you got it right.
South Dakota DPS mock test
Answer all 25 questions first. Nothing is marked until you submit the whole test, so the score shows how ready you are, and then you review every answer with its explanation.

- To pass: 80% correct

- Unanswered questions count as wrong
Time: We found no published time limit for the South Dakota knowledge test.
What's on the South Dakota DMV Test Simulator
You need at least 80% correct. The DPS does not publish the number of questions on the test, so the number you can miss depends on the test you get - on our 25-question simulator that is 5.

2. On an undivided South Dakota highway, you may not make a U-turn on a curve or near a hilltop where other drivers cannot see you from within:
- A. 200 feet
- B. 300 feet
- C. 500 feet (correct)

3. What does a sign showing a car with curved skid marks indicate?
- A. Winding road
- B. Slippery when wet (correct)
- C. Sharp curve
- D. Loose gravel ahead
Why: A yellow warning sign with a car and curved skid lines means the road is slippery when wet. Slow down and increase following distance in rain or snow.
4. Hydroplaning is most likely to occur when:
- A. Driving slowly through deep, soft snow on a hill
- B. Driving fast on a wet road, mainly with worn tires (correct)
- C. Driving on dry pavement on a very hot day
- D. Braking gently on an icy road in the cold
Why: Hydroplaning happens when a layer of water builds between your tires and the road, usually at higher speeds on wet pavement. Worn tires and standing water increase the risk. Slow down in the rain to keep tire contact with the road.
5. What must you do when you see this sign?
- A. Slow down and go if no one is coming
- B. Stop fully, then go when it is safe (correct)
- C. Stop only if cross traffic is coming
- D. Stop, then go ahead of cross traffic
Why: This is a STOP sign (red octagon). You must come to a complete stop at the stop line, crosswalk, or before the intersection, then proceed only when it is safe.

6. Aggressive driving behaviors such as tailgating, weaving, and excessive speeding:
- A. Save enough time to make up for the added risk
- B. Raise crash risk and can lead to reckless charges (correct)
- C. Are only illegal when they cause a crash
- D. Are safe for skilled drivers in light traffic
Why: Aggressive driving dramatically increases the risk of a crash and can lead to reckless driving citations, points, and higher insurance. The time saved is minimal compared to the danger created.
