1. 1. After a crash involving an unattended parked vehicle, what must you do if you cannot find the owner?

   1. Drive away if the damage appears minor
   2. Leave identifying and crash information where the owner can find it
   3. Wait 24 hours before notifying anyone
   4. Move the parked vehicle before leaving a note
   Show answer

   Leave identifying and crash information where the owner can find it. If you damage unattended property and cannot locate the owner, South Dakota says to contact law enforcement and leave information where the owner can find it. Driving away because damage looks minor is still leaving the scene without the required notice. The cue is an empty parked vehicle after contact: stop, try to locate the owner, call the nearest law enforcement agency, and leave your name, license, plate, date, time, and damage information.

2. 2. How should a driver respond to deer eyes reflecting beside the road?

   1. Speed up before more deer reach the pavement
   2. Swerve toward the shoulder to scare the deer away
   3. Slow down, blow the horn, and be ready to stop
   4. Dim all lights and coast past silently
   Show answer

   Slow down, blow the horn, and be ready to stop. If headlights reflect in deer eyes beside the road, slow down, blow the horn, and prepare to stop. The manual also says to always watch for more than one deer, so one reflection can mean more animals nearby. Swerving toward the shoulder is wrong because it can send you off the road or into another hazard. Scan the roadside at dusk and dawn for reflecting eyes, and reduce speed early when you see them.

3. 3. At a flashing red traffic light, what action is required?

   1. Treat it like a yield sign and roll through if clear
   2. Stop only when pedestrians are in a marked crosswalk
   3. Proceed without stopping because cross traffic has yellow
   4. Come to a complete stop, then go when safe
   Show answer

   Come to a complete stop, then go when safe. A flashing red light has the same meaning as a stop sign. You must come to a complete stop and may proceed only when the way is safe. Rolling through as though it were a yield sign skips the full stop that South Dakota requires. The cue is the red flash: treat the intersection like a stop controlled approach, check cross traffic and pedestrians, and move only after yielding where needed.

4. 4. According to the South Dakota manual, when does impairment from alcohol start?

   1. Only at 0.08% BAC or more
   2. With the first drink
   3. After three drinks in one hour
   4. Only after the drinker feels dizzy
   Show answer

   With the first drink. South Dakota says the best advice is not to drive at all if you have consumed alcohol or other drugs, because impairment starts with the first drink. Even one drink can affect your ability to drive. Alcohol reduces judgment, vision, color distinction, and reaction time. The manual adds that even under 0.08% BAC you are still impaired and can still be convicted. Waiting until you feel dizzy, or counting on a certain number of drinks, does not protect you.

5. 5. How must vehicles in a South Dakota funeral procession identify themselves?

   1. They must use hazard flashers only
   2. They must have headlights on
   3. They must display a temporary permit in the windshield
   4. They must honk before each intersection
   Show answer

   They must have headlights on. Vehicles following in a funeral procession are required to have headlights on. That lighting helps other drivers recognize the group and avoid cutting into it. Hazard flashers may seem noticeable, but the manual specifies headlights, not a different warning device. The practical cue is a line of vehicles moving together with headlights illuminated; after the first vehicle has handled traffic controls, do not insert your vehicle into the procession or break it apart.

6. 6. If your brakes fail while driving and the parking brake does not stop you, what should you do next?

   1. Turn off the engine and look for a safe place to slow to a stop
   2. Shift to park while moving at highway speed
   3. Keep driving until the brakes cool down
   4. Pump the accelerator to restore hydraulic pressure
   Show answer

   Turn off the engine and look for a safe place to slow to a stop. For brake failure, South Dakota first describes using the parking brake carefully. If that fails, turn off the engine and look for a safe place where the vehicle can slow to a stop off the roadway. Keeping the trip going is wrong because the manual says not to continue without working brakes. The cue is loss of stopping power after the parking brake attempt: aim for an escape path, reduce speed, and get out of traffic.

7. 7. A South Dakota driver is convicted of failure to yield the right of way in Iowa. How does South Dakota treat the conviction?

   1. It is ignored because it happened in another state
   2. It counts only if the driver was on an interstate
   3. It is recorded but never assessed points
   4. Points are assessed just as if it were committed in South Dakota
   Show answer

   Points are assessed just as if it were committed in South Dakota. South Dakota assesses points on out-of-state convictions just as if they were committed in South Dakota, so a failure to yield conviction in Iowa carries the same 4 points it would at home. The offense is not ignored, and there is no interstate-only rule or record-only treatment. Keep in mind that the state assesses no points for speeding, standing, parking, equipment, size or weight violations, wherever they occur. A driver who reaches the suspension threshold through out-of-state points may ask for a hearing before the suspension.

8. 8. How long is a South Dakota driver's first point system suspension?

   1. A 30 day suspension
   2. A 6 month suspension
   3. A 60 day suspension
   4. A 1 year suspension
   Show answer

   A 60 day suspension. South Dakota's periods of suspension under the point system are 60 days for a first suspension, 6 months for a second, and 1 year for any later suspension. Thirty days is not on this table; it is the minimum license loss for a first DWI and a first Zero Tolerance offense. Six months and one year are the escalated periods for repeat point suspensions.

9. 9. A South Dakota driver's license was suspended (not revoked). What is needed to reinstate it?

   1. Full vision, knowledge, and driving tests every time
   2. A $225 fee and a court hearing
   3. An application fee and a $50 reinstatement fee, with no testing unless the license has expired
   4. Nothing, it reinstates automatically
   Show answer

   An application fee and a $50 reinstatement fee, with no testing unless the license has expired. Following a suspension, South Dakota requires no testing unless the license has expired, only an application fee and a $50 reinstatement fee. A revocation is stricter: vision and knowledge tests are required along with the application fee and a $50 to $225 reinstatement fee, which is where the $225 figure comes from. Reinstatement is never automatic after a withdrawal of the privilege.

10. 10. When entering a roundabout, what is the safe entry rule?

    
    1. Enter only when there is a safe gap in traffic
    2. Stop inside the circle to choose your exit
    3. Force circulating traffic to yield to your vehicle
    4. Accelerate across the truck apron
    Show answer

    Enter only when there is a safe gap in traffic. South Dakota lists roundabout entry as a slow, yielding maneuver followed by entry only when a usable gap appears. Forcing traffic already in the circle reverses the rule and raises crash risk. The cue is traffic approaching from the left within the circle; wait for a gap, then enter and keep speed low. Do not stop inside the roundabout unless traffic conditions force it; keep moving toward your exit after entering.

11. 11. What condition should your windshield wipers be in before driving in rain or snow?

    1. They may be skipped if the windshield is recently cleaned
    2. They only need to function on the driver's side
    3. They should work well and clear water properly
    4. They should be replaced only after winter ends
    Show answer

    They should work well and clear water properly. South Dakota treats wipers as part of keeping the vehicle safe to operate. They should be in good condition, and blades that do not clear water well should be replaced. The driver's-side-only choice is too narrow because poor clearing anywhere can reduce visibility. Use the cue of streaking, skipping, or water left on the glass; those signs mean maintenance is needed before bad weather driving.

12. 12. On a two-lane South Dakota highway, you approach a stopped vehicle using amber, yellow, or blue warning lights. If the posted limit is above 20 mph, how much must you slow?

    1. At least 20 mph below the posted speed limit
    2. Exactly 5 mph below the posted speed limit
    3. To 45 mph in every case
    4. Only enough to avoid crossing the centerline
    Show answer

    At least 20 mph below the posted speed limit. On a two-lane highway, South Dakota substitutes a speed reduction for the lane-change rule. If the posted limit is above 20 mph, drivers must slow at least 20 mph below that limit before passing the stopped vehicle. The 5-mph choice applies only when the posted limit is 20 mph or less, so it changes the condition. The cue is the posted number: above 20, subtract 20 before you pass with caution.

13. 13. What action does this red and white downward-pointing triangle require?

    
    1. Accelerate to join traffic before the intersection
    2. Enter only after a green arrow appears
    3. Stop for thirty seconds even when the road is empty
    4. Slow down and yield to traffic in the intersection or roadway
    Show answer

    Slow down and yield to traffic in the intersection or roadway. The yield sign tells a driver to slow and give right-of-way to traffic in the intersection being crossed or the roadway being entered. A fixed thirty-second stop is not the South Dakota rule; stopping may be needed, but only because traffic conditions require it. Use the inverted triangle as the cue to check both approaches early and be ready to wait.

14. 14. What does the pictured DO NOT ENTER sign prohibit?

    
    1. Entering the roadway where it is posted
    2. Parking while allowing through travel
    3. Passing another vehicle
    4. Making only a left turn
    Show answer

    Entering the roadway where it is posted. DO NOT ENTER is one of the regulatory signs shown in the South Dakota manual. Regulatory signs state specific laws that you must obey, including rules for traffic direction. The words on this sign give the rule directly: you must not enter the roadway where it is posted. It is not a parking sign, a passing rule, or a ban on only one kind of turn. If you see this sign at a street or ramp you were about to use, do not drive in; find another route.

15. 15. Which passenger car is exempt from the listed South Dakota child restraint and youth seatbelt provisions?

    1. A pickup being driven less than five miles from home
    2. A passenger car made before 1966 with no seatbelts installed
    3. A car carrying only passengers age twelve or younger
    4. A vehicle with air bags for every seating position
    Show answer

    A passenger car made before 1966 with no seatbelts installed. South Dakota's exemption is narrow: the listed child restraint and youth seatbelt provisions do not apply to passenger cars manufactured before 1966 that have not been equipped with seatbelts. Air bags do not create an exemption, since the manual says belts still matter with air bags. The cue is the vehicle's age and original or current belt equipment, not trip length or passenger age alone.

16. 16. What does this STOP AHEAD warning sign prepare you for?

    
    1. A stop sign ahead
    2. A yield sign after the next curve
    3. A minimum speed zone
    4. A lane reserved for buses
    Show answer

    A stop sign ahead. The South Dakota warning sign table names Stop Sign Ahead as a common warning sign. A minimum speed zone would be shown by a regulatory speed sign, not this advance warning. The cue is the small stop symbol on the yellow sign; begin checking your mirror and reducing speed so the actual stop sign does not require a hard last-second brake.

17. 17. For a driver 21 or older, what BAC does the South Dakota manual say is evidence of driving under the influence of alcohol?

    1. 0.12% or more
    2. 0.02% or more
    3. 0.04% or more
    4. 0.08% or more
    Show answer

    0.08% or more. For drivers who are not under the special underage rule, South Dakota uses 0.08% BAC or more as evidence of driving under the influence of alcohol. The 0.02% option belongs to drivers under 21 and should not be confused with the adult DWI threshold. The cue is the driver’s age bracket: adults should remember 0.08% as the evidence level, while also recognizing that unsafe impairment can begin before that point.

18. 18. What do pavement markings do for drivers?

    1. Apply to pedestrians but not to drivers
    2. Replace the traffic signals at intersections
    3. Mark only decorative boundaries on highways
    4. Give directions or warnings and show lane or stopping rules
    Show answer

    Give directions or warnings and show lane or stopping rules. Pavement markings are roadway instructions. They divide lanes, show passing and lane-use rules, mark crosswalks, and identify where to stop. Calling them decorative ignores their traffic-control role. The cue is paint on the road surface, such as arrows, words, stop lines, lane lines, and crosswalk bars. Treat markings as part of the control system along with signs and lights, especially where lanes split or turn.

19. 19. What do the shape, color, symbols, and words of traffic signs help you identify?

    1. The age of the driver who installed it
    2. The type of information the sign provides
    3. The exact fine for every possible violation
    4. The vehicle weight of the nearest truck
    Show answer

    The type of information the sign provides. South Dakota tells drivers to read a sign's shape, color, symbols, and words as clues to the information it gives. Those features do not tell you who installed it or every fine amount. The cue is the sign's visual family: color and shape help separate warnings, regulations, services, destinations, and railroad information. When uncertain, classify the sign by its visual category before deciding whether it warns, directs, prohibits, or guides.

20. 20. You miss your exit on a South Dakota interstate. What should you do?

    1. Stop on the shoulder and back up to the exit
    2. Cross the median to turn around
    3. Go on to the next exit
    4. Slow down in the right lane and back up when traffic clears
    Show answer

    Go on to the next exit. If you miss your exit, South Dakota tells you to go on to the next exit. Backing up on the interstate is prohibited under any circumstances, so stopping on the shoulder or in a lane to back up is not allowed, even when traffic looks light. Plan ahead for your exit, and if you pass it, accept the short extra drive to the next exit and return from there. The manual also tells you to stay in the right lane unless you are passing.
