1. An arrow panel in a work zone shows four flashing lamps in caution mode instead of an arrow. What does that display mean?
Show answer
Answer A: Warning only, so pass the work area with caution in your current lane
Caution mode gives a general warning without directing a lane change, so drivers stay alert and pass the activity with care.
-
2. Which vehicle is most affected by a strong side wind?
Show answer
Answer D: A van or a car towing a tall trailer
Wind pushes against the side area of a vehicle, so tall boxy shapes and trailers are moved far more than low heavy ones.
-
3. You are driving on a road covered with a layer of wet fallen leaves. What should you expect?
Show answer
Answer B: As little grip as on ice, plus hidden markings and hidden holes
Wet leaves are as slippery as ice and they hide the lane lines and any potholes underneath, so slow well before curves and stops.
-
4. A sign at the intersection prohibits U-turns, but the opening looks wide and clear. What may you do?
Show answer
Answer B: Obey the sign and turn around somewhere else
A prohibition applies whatever the traffic looks like at that moment, usually because of sight distance or conflicts you cannot see from the lane.
-
5. A wide crosswalk you are turning across has a refuge island in the middle. What should you assume about people standing on it?
Show answer
Answer D: They may step off the island into your path at any moment
An island is a pause in a crossing, not the end of one, so treat anyone on it as a pedestrian who is still crossing.
-
6. You are driving down a parking aisle and reach the main lane that runs along the front of the store. What is the usual rule?
Show answer
Answer C: The main through lane has the right of way over the vehicles leaving the aisles
In a parking lot the wide lane that runs across the ends of the aisles works like a through road, and drivers leaving an aisle yield to it.
-
7. A yellow lamp flashes above a warning sign at a sharp curve. What does it ask of a driver?
Show answer
Answer D: Slow down and pass the point with extra care
A warning beacon draws attention to the sign it is mounted with, and the message of the sign is what the driver must act on.
-
8. Who must be belted under South Dakota's safety seat belt statute?
Show answer
Answer C: The operator and every front seat passenger
The statute requires the operator and front seat passengers to be belted, and the driver must also secure front seat passengers who are at least five but under 18.
-
9. What is the most common cause of rear-end collisions?
Show answer
Answer C: Following too closely to stop in time
A driver who leaves too little space has no room to perceive, react and brake when the vehicle ahead slows, which is why space management prevents rear-end crashes.
-
10. What must a driver be ready to do along the stretch of road where this sign is posted?
Show answer
Answer D: Slow down and stop for a child who steps into the roadway
Children misjudge speed and distance and act without warning, so the driver reduces speed, covers the brake and scans the sidewalks and parked vehicles.
-
11. Why should your thumbs rest along the rim rather than hook inside the spokes?
Show answer
Answer D: A jolt can spin the wheel and injure hooked thumbs
A pothole or a dropped wheel can snap the wheel round violently, and thumbs hooked through the spokes are trapped when it happens.
-
12. What happens when the Department of Public Safety receives a conviction record showing a minor violated the conditions of an instruction permit or restricted minor's permit?
Show answer
Answer C: The department suspends the permit or driving privileges for 30 days
A conviction for violating permit conditions triggers a 30-day suspension of the minor's permit or driving privileges.
-
13. What makes up the total distance needed to bring a vehicle to a stop?
Show answer
Answer A: The distance covered while you perceive the hazard, the distance covered while you react, and the braking distance
Total stopping distance combines the ground covered while you notice the hazard, the ground covered while you move your foot to the brake, and the ground covered while the brakes slow the vehicle.
-
14. You want to reverse direction but the street is too narrow for a U-turn. What is the alternative?
Show answer
Answer D: Make a three-point turn, or go around the block in heavy traffic
Where there is not enough width for a U-turn, the three-point turn does the job in stages, and on a busy street going around the block is safer still.
-
15. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?
Show answer
Answer B: In the first traffic lane to the left of the bike lane
A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.
-
16. Except for specific situations named in the law, what is the maximum length of time the Department of Public Safety may suspend a South Dakota driver license under its general suspension authority?
Show answer
Answer C: One year
The department's general suspension authority caps a suspension at one year, apart from listed statutory exceptions.
-
17. How should the outside mirrors be aimed to reduce your blind spots?
Show answer
Answer A: Outward, so each one covers the lane beside you rather than repeating the inside mirror
Mirrors aimed too far inward show you the same road three times and leave a large gap beside the vehicle, so aiming them outward shrinks the blind spot.
-
18. A wheel comes off your car while you are driving. What should you do?
Show answer
Answer A: Hold the wheel firmly, ease off the gas and steer gently to the shoulder
A firm grip and a gradual slowing keep the vehicle straight, while hard or sudden braking makes a damaged corner pull the car out of line.
-
19. A disabled vehicle is blocking your lane on a two-lane road with a single solid yellow line on your side. What should you do?
Show answer
Answer C: Wait until the oncoming lane is clear, then go around carefully
The solid line prohibits overtaking a moving vehicle, but in most states a driver may go around an obstruction such as a disabled vehicle once the oncoming lane is clear and the move can be made safely.
-
20. A ball rolls into the street from between parked cars ahead of you. What should you expect and do?
Show answer
Answer A: Expect a child to follow it and be ready to stop
A ball is usually followed by a child who is watching the ball and not the traffic. Slow down and be prepared to stop immediately.
-
21. How do strong emotions affect driving?
Show answer
Answer B: They narrow your attention and make risky decisions more likely
Anger, worry and excitement all take attention away from the driving task and push drivers toward decisions they would not normally make.
-
22. Where is a U-turn most clearly unsafe and generally prohibited?
Show answer
Answer D: On a curve or near a hill crest, where other drivers cannot see you
U-turns are barred where approaching drivers cannot see you in time, such as on a curve or near the top of a hill.
-
23. What is a marked loading zone for?
Show answer
Answer A: Loading and unloading only, not for general parking
A loading zone is reserved for actively loading or unloading goods or passengers; leaving a vehicle there for other reasons is a parking violation.
-
24. What do the grooves in a tire tread do on a flooded road surface?
Show answer
Answer B: They give the water a way to escape so the tread can touch the road
Tread grooves pump water out from under the tire so rubber can meet pavement. A worn tread moves less water, so hydroplaning starts sooner.
-
25. You have fitted the small temporary spare tire after a flat. What should you keep in mind?
Show answer
Answer C: It is meant for low speed and short distances until the regular tire is repaired
Compact spares have limited grip, handling and durability. Follow the speed and distance limits printed on the tire and get the regular tire fixed soon.
