South Dakota Permit Practice Test 2

A second full-length South Dakota practice test: 30 fresh multiple-choice questions with zero repeats from Test 1. You need 80% correct to pass the real DPS Knowledge Test.

  1. 1. On a two-lane South Dakota highway you approach a stopped ambulance using flashing lights. What does the move-over law require?

    Show answer & explanation

    Correct answer: A. Where South Dakota drivers cannot move over a lane, the law requires slowing to at least 20 mph under the posted limit, beginning 300 feet before the stopped vehicle. Less speed near responders means a much shorter stopping distance.

  2. 2. You are pulling out of a driveway onto a public street. What must you do?

    Show answer & explanation

    Correct answer: D. A driver entering a road from a driveway, alley, or private road must yield to sidewalk pedestrians and to all traffic already on the roadway. Public-road users cannot predict your exit, so the burden is on the driver emerging.

  3. 3. Your headlights suddenly go dark while you are driving at night. What should you do first?

    Show answer & explanation

    Correct answer: C. First flick the headlight switch and dimmer, since the problem may be a loose connection; then use parking, hazard, or turn lights to stay visible while you leave the road. Never keep driving blind hoping the lights return.

  4. 4. You are driving through a residential district in South Dakota and see no speed limit signs. What is the default speed limit?

    Show answer & explanation

    Correct answer: C. Where no sign is posted, South Dakota's default residential limit is 25 mph. Homes mean driveways, pets, and kids near the road, so the default stays low. A posted sign always overrides the default, so watch for one.

  5. 5. You are passing a slow truck on a South Dakota highway posted at the state's maximum limit. Even while passing, your legal ceiling stays at which speed?

    Show answer & explanation

    Correct answer: B. Passing grants zero extra speed allowance; in South Dakota the ceiling on those top-posted highways stays 80 mph. If you cannot complete the pass within the limit, wait for a better gap. The limit binds every maneuver, always.

  6. 6. In South Dakota, a driver who is 21 or older commits a per-se drunk-driving offense once their blood alcohol concentration reaches which level?

    Show answer & explanation

    Correct answer: B. 'Per se' means the number alone proves the offense. In South Dakota, that number is 0.08%. No other proof of bad driving is needed at that level, and alcohol can still impair you below it.

  7. 7. You are low on fuel on a long highway drive. Signs of which color point you to services such as gas, food, lodging, and hospitals?

    Show answer & explanation

    Correct answer: B. Blue signs mark motorist services, including fuel, food, lodging, rest areas, and hospitals. They let travelers plan a stop before leaving the highway. When your body or your car needs something, look for blue.

  8. 8. How does alcohol change the skills you rely on to drive?

    Show answer & explanation

    Correct answer: B. Alcohol slows your reactions, throws off coordination, and blurs and narrows vision, so every core driving skill suffers at once. Impairment starts before you feel drunk. Think of alcohol as turning down every dial you drive with.

  9. 9. You reach a stop sign at an intersection that has a painted stop line. Where must you bring your vehicle to a complete stop?

    Show answer & explanation

    Correct answer: A. At a stop sign you must stop completely before the stop line; with no line, stop before the crosswalk or the intersection edge. Stopping short protects people in the crosswalk. If you need a better view, creep forward only after the full stop.

  10. 10. Your GPS routes you through a South Dakota neighborhood of homes and parked cars with no posted speed limit. State law caps your speed there at what value?

    Show answer & explanation

    Correct answer: D. State law gives unposted residential areas in South Dakota a default cap of 25 mph. Parked cars shrink your view of crossing pedestrians, which is exactly why the cap is low. Posted signs, where present, replace the default.

  11. 11. You are on an entrance ramp about to merge onto a freeway. Who is responsible for yielding?

    Show answer & explanation

    Correct answer: A. Drivers merging onto a freeway must yield to traffic already on it, using the ramp to match speed and slide into a gap. Through traffic cannot stop safely at highway speeds, so the entering driver adapts.

  12. 12. A yellow diamond sign ahead displays a bold T symbol. What does this sign mean you will have to do soon?

    Show answer & explanation

    Correct answer: D. A T-symbol warning means your road dead-ends at a cross street, so you must slow, yield to crossing traffic, and turn left or right. The letter T shows exactly how the roads meet ahead.

  13. 13. How much of a traffic lane is a motorcycle entitled to use?

    Show answer & explanation

    Correct answer: D. A motorcycle is entitled to a complete traffic lane, and you may not squeeze past one inside that lane. Riders need the full width to dodge hazards. Treat a motorcycle's lane like a car's lane: whole and off-limits.

  14. 14. Why is it illegal to park on a sidewalk or in a crosswalk?

    Show answer & explanation

    Correct answer: B. Sidewalks and crosswalks are reserved walking space; a parked car there pushes pedestrians, strollers, and wheelchairs out into traffic lanes. The law keeps walking paths continuous and safe. If people walk there, your car never belongs there.

  15. 15. Wide white stripes cross the pavement ahead, marking a crosswalk. What do these markings require of you as a driver?

    Show answer & explanation

    Correct answer: C. Crosswalk stripes show where pedestrians are expected to cross, and drivers must yield to people within them. You stop only when someone is crossing or a sign or signal requires it. Painted stripes mean feet ahead.

  16. 16. At a crosswalk signal, what is the difference between the walking-person symbol and the raised-hand symbol?

    Show answer & explanation

    Correct answer: C. The walking-person symbol invites pedestrians to begin crossing, while the raised hand warns them not to start; a flashing hand means finish crossing if already in the street. Drivers should expect people in the crosswalk during these phases.

  17. 17. What is a reliable way to judge whether you are following the vehicle ahead too closely?

    Show answer & explanation

    Correct answer: A. Pick a fixed marker like a pole or shadow; when the vehicle ahead passes it, count seconds until you arrive. Counting seconds works at any speed, unlike guessing car lengths. The road itself becomes your measuring tape.

  18. 18. What does a South Dakota driver under 21 face when convicted under the state's zero-tolerance alcohol law?

    Show answer & explanation

    Correct answer: D. South Dakota treats underage drinking and driving as a Class 2 misdemeanor, and the court suspends the driver license on conviction. Zero tolerance means the penalty lands far below the impairment threshold that applies to adults.

  19. 19. While you wait to turn, the green arrow changes to a steady yellow arrow. What is the signal telling you?

    Show answer & explanation

    Correct answer: D. A steady yellow arrow warns that the protected turning phase is about to end. Stop if you can do so safely; drivers already at the point of no return may finish the turn cautiously. Yellow arrow means wrap up, not speed up.

  20. 20. A friend in South Dakota says, 'I feel fine, so I can drive.' Feelings aside, the law sets the illegal BAC for drivers 21 and older at which number?

    Show answer & explanation

    Correct answer: B. Feeling fine proves nothing; alcohol dulls the very judgment you use to check yourself. In South Dakota, 0.08% is the per-se limit for adults, and measurable impairment often shows up well before a driver reaches it.

  21. 21. Why do states phase in driving privileges through graduated driver licensing (GDL) programs?

    Show answer & explanation

    Correct answer: B. GDL programs add privileges in stages, from supervised practice to restricted solo driving to a full license, because crash risk peaks in a driver's first months. Skills grow with mileage, so the system lets experience catch up first.

  22. 22. On any road sign, what does the color red always signal to drivers?

    Show answer & explanation

    Correct answer: D. Red is reserved for the strongest commands: stop, yield, do not enter, and wrong way. It marks actions that are forbidden or must halt. When red appears, something about your movement has to change right now.

  23. 23. South Dakota enforces 'zero tolerance' for underage drinking and driving. In practice, a driver under 21 violates this law at what BAC?

    Show answer & explanation

    Correct answer: A. Zero tolerance in South Dakota means the under-21 line sits at 0.02%, so even one drink can end in a suspended license. The memory hook is simple: under 21 means zero drinks before you drive.

  24. 24. What do financial responsibility laws require of you before you drive?

    Show answer & explanation

    Correct answer: D. Every state requires drivers to show they can pay for harm they cause, and auto insurance is the usual proof. Crashes create huge bills in seconds, so the rule protects victims. Simple memory hook: no coverage, no keys.

  25. 25. In South Dakota, what is the youngest age at which you can apply for a learner's permit?

    Show answer & explanation

    Correct answer: B. South Dakota issues learner's permits starting at age 14. The permit opens the first stage of graduated licensing, where you build skills with a supervising adult before earning fuller privileges. Know your state's number; it varies nationwide.

  26. 26. You hit a stretch of heavy rain and patchy fog on the highway. How should you adjust your speed?

    Show answer & explanation

    Correct answer: B. In rain or fog, reduce speed until you could stop within the distance you can actually see, since wet pavement stretches stopping distance and fog hides hazards. Drive by sight distance: if you cannot see it, slow for it.

  27. 27. Setting cruise control on a rural South Dakota interstate posted at the state maximum, you should set it no higher than which speed?

    Show answer & explanation

    Correct answer: B. The state maximum in South Dakota is 80 mph, so cruise control should never be set above it where that limit is posted. Think of the posted limit as a ceiling for ideal conditions, never a required speed.

  28. 28. What is the maximum lawful speed when you pass a South Dakota school during recess or at opening and closing hours?

    Show answer & explanation

    Correct answer: A. South Dakota caps speed at 15 mph when passing a school at recess or while children arrive and leave. Kids step into the street unpredictably, and 15 mph leaves room to stop. Breaking this rule is a Class 2 misdemeanor.

  29. 29. Under implied-consent laws, what have you already agreed to simply by driving on public roads?

    Show answer & explanation

    Correct answer: D. Every state has an implied-consent law: by driving, you have already agreed to a breath, blood, or urine test after a lawful impaired-driving arrest. Driving is a privilege, and testing is part of the deal you accepted.

  30. 30. Unless the township board posts a different zone, what is the speed limit on a South Dakota township road?

    Show answer & explanation

    Correct answer: C. South Dakota limits township roads to 55 mph unless the township board posts a different zone. These narrow rural routes hide blind intersections and farm equipment, so the statutory cap sits below the 65 mph highway default.
