  1. 1. Your light turns green and a driver on the cross street enters against a red. What should you do?

    Show answer

    Answer D: Hold back and let that vehicle go through

    Giving up a right of way you are entitled to is the only way to avoid a crash with a driver who has already failed to yield.

  2. 2. You have just passed a vehicle on a two-lane road. When may you return to your lane?

    Show answer

    Answer B: When you can see the whole vehicle in your inside mirror

    Seeing the entire vehicle you passed in your rearview mirror shows there is room to pull back in without cutting it off.

  3. 3. Your wiper blades smear the windshield instead of clearing it. What should you do?

    Show answer

    Answer C: Replace the blades, because smearing means that the rubber is worn

    Worn or hardened rubber cannot wipe cleanly, and blades are cheap compared with driving without a clear view.

  4. 4. You are on a one-way street with two marked lanes. May you pass a slower vehicle on the right?

    Show answer

    Answer A: Yes, using the right lane, provided that the move is safe and signaled

    On a roadway with two or more marked lanes in your direction, moving into the free lane and going by is a normal lane change rather than an unlawful pass.

  5. 5. You notice at night that one of your headlights has burned out. What should you do?

    Show answer

    Answer B: Get it replaced promptly, because other drivers may take you for a motorcycle

    A single light makes your vehicle look narrower and further away, so other drivers misjudge you, and one light is also illegal.

  6. 6. Which of these is true of the roadway a driver is being sent onto here?

    An orange rectangle with black lettering and a black arrow
    Show answer

    Answer D: Its own signs, signals and speed limits govern for the whole way around

    The alternate route is an ordinary public road, so every control posted on it governs as usual; being sent that way grants no extra priority and no relief from the limits in force there.

  7. 7. What does the implied consent law mean for drivers?

    Show answer

    Answer D: By driving, you have agreed to a chemical test if lawfully arrested for impaired driving

    Holding a license and driving on public roads is treated as consent to breath, blood or urine testing when an officer has grounds to arrest you. Refusing normally brings its own license penalties.

  8. 8. A square sign with a red field, a wide white horizontal bar and the words DO NOT ENTER tells a driver that

    Show answer

    Answer B: the roadway ahead must not be entered from that point

    The do not enter sign is posted at the end of a one-way roadway or ramp to keep traffic from driving into it against the flow.

  9. 9. Your phone is in a mount on the dashboard rather than in your hand. What is true?

    Show answer

    Answer B: It still takes your eyes and mind off the road

    A mount solves the hand problem but not the eye or the mind problem, and reading or tapping a mounted screen costs the same seconds of attention.

  10. 10. A steady green downward arrow is displayed above the lane you are in. What does it tell you?

    Show answer

    Answer A: You may drive in that lane

    A green downward arrow means the lane beneath it is open for travel in your direction.

  11. 11. Which headlight setting should you use in dense fog?

    Show answer

    Answer B: Low beams

    High beams reflect off the water droplets in fog and bounce glare back at you, while low beams aim downward and light the road without that mirror effect.

  12. 12. What is the South Dakota Department of Public Safety's application fee for an original or renewal driver license?

    Show answer

    Answer B: Thirty-eight dollars

    State law sets the original or renewal driver license fee at thirty-eight dollars, higher than the twenty-dollar fee for a duplicate or address change.

  13. 13. Travelling at about 55 mph on dry pavement, roughly how much room does an average car need to perceive, react and stop?

    Show answer

    Answer D: About 300 feet, close to the length of a football field

    Reaction distance plus braking distance at 55 mph comes to roughly 300 feet on good dry pavement, and considerably more on a wet or loose surface.

  14. 14. You have stopped on an uphill grade close behind a large truck at a traffic signal. What is the risk?

    Show answer

    Answer B: The truck may roll back into you when it starts to move

    Heavy vehicles can roll backward a short distance when the driver moves from the brake to the accelerator on a hill. Leave extra room when stopped behind a truck on a grade.

  15. 15. What is the maximum gross vehicle weight a South Dakota restricted minor's permit holder may generally operate?

    Show answer

    Answer B: 20,000 pounds

    A restricted minor's permit does not authorize operating a vehicle over 20,000 pounds gross vehicle weight, apart from an exception for certain unregistered self-propelled farm machinery.

  16. 16. Traffic in your lane is backed up and the paved shoulder looks clear. May you drive along it to get past?

    Show answer

    Answer C: No, the shoulder is not a travel lane

    Passing must be done within the roadway; driving on the shoulder to get around traffic is prohibited and surprises anyone entering from the right.

  17. 17. A bicyclist in the bike lane ahead of you signals and starts to move left toward the turn lane. What should you do?

    Show answer

    Answer A: Slow down and let the rider move across

    A bicyclist who needs to leave the bike lane to turn left is changing lanes like any driver, and following traffic should make room.

  18. 18. You and the driver facing you both have stop signs at a two-way stop. You are going straight and that driver is turning left. Who has the right of way?

    Show answer

    Answer B: You do, and the turning driver must wait

    Between two opposing drivers who both stopped, the one going straight goes first and the left-turning driver yields.

  19. 19. What should a driver expect a short distance beyond this sign?

    A yellow diamond showing a black cross
    Show answer

    Answer C: Another road crossing the one being traveled

    Traffic may enter or cross from either side at the intersection ahead, so the driver should ease off, cover the brake and check both approaches.

  20. 20. A yellow diamond shows an arrow bent into a series of reversing turns. What does it warn about?

    Show answer

    Answer A: Three or more changes of direction close together

    The winding road sign replaces a string of separate curve signs where several bends follow one another with only short straights between them.

  21. 21. When should you adjust your seat, mirrors and steering wheel?

    Show answer

    Answer B: Before you start moving

    Adjusting the driving position while moving takes your attention and often your hands away from driving. Make every adjustment while parked, every time.

  22. 22. You are turning left from a one-way street onto a two-way street. How should the turn be made?

    Show answer

    Answer B: Start in the far left lane and finish just to the right of the center line

    Left turns begin from the lane nearest the left edge of the street you are leaving and must finish on the right-hand side of the center line of a two-way street.

  23. 23. At an intersection where turning right on red is permitted and no sign prohibits it, what must you do before turning?

    Show answer

    Answer A: Come to a complete stop and yield to pedestrians and cross traffic

    A right turn on red is allowed only after a full stop, and the turning driver must yield to pedestrians in the crosswalk and to traffic already using the intersection.

  24. 24. Which warning sign keeps its yellow background even when it is used inside a work zone?

    Show answer

    Answer D: The grade crossing advance warning sign

    The round grade crossing advance warning sign keeps its black legend on yellow inside temporary traffic control zones because the railroad hazard it describes is not temporary.

  25. 25. What is the minimum lawful speed on South Dakota's interstate highways, absent a special permit?

    Show answer

    Answer B: 40 miles per hour

    Driving an interstate highway below 40 miles per hour is a Class 2 misdemeanor unless the vehicle operates under a department-issued permit.
