1. Your light turns green, but a vehicle from the cross street is still finishing a turn inside the intersection. What should you do?
Show answer
Answer B: Wait until that vehicle has cleared the intersection
A green indication lets you proceed only after yielding to pedestrians in the crosswalk and to vehicles already lawfully within the intersection.
-
2. Why would this sign be installed on an approach?
Show answer
Answer B: Because the signal cannot be seen from far enough back for a driver to react in time
Advance notice of a signal is used where a crest, a curve, trees or a building keep the signal heads out of view until a driver is already too close to stop comfortably.
-
3. Your light turns green, but a vehicle is still in the middle of the intersection. What should you do?
Show answer
Answer D: Wait until the intersection is clear before you move ahead
A green light means go only when the way is clear. Drivers already inside the intersection must be allowed to finish crossing.
-
4. You are following a large truck on a two-lane road and cannot see past it. What should you do before deciding to pass?
Show answer
Answer D: Drop back so that your view of the road ahead opens up
Distance is what buys you a view around a large vehicle, and no decision to pass can be made from a position where you cannot see.
-
5. Which of these places should never be used to turn your vehicle around?
Show answer
Answer C: The driveway of a fire station or the roadway in front of it
Turning around in or in front of a fire station driveway can block emergency vehicles leaving, and most states prohibit it.
-
6. An upward-pointing pentagon with a yellow legend and border on a blue background is used as
Show answer
Answer D: a county route marker
The pentagon serves both the school warning series and county route markers, and the blue background with yellow legend identifies the county route version.
-
7. A friend who has been drinking insists on driving home. What is the right thing to do?
Show answer
Answer B: Take the keys and arrange a sober ride, even if the friend objects
An impaired driver is dangerous on any street at any speed, and coffee does not lower blood alcohol. Keeping the keys and finding another way home is the only safe choice.
-
8. On a rural road, the driver of a slow farm tractor ahead of you signals a left turn even though there is no road or driveway in sight. What should you do?
Show answer
Answer B: Stay behind the tractor, because it may be turning into a field entrance
Farm equipment often turns into fields through gaps you cannot see, and it may swing wide to do so. Passing a vehicle that is signaling a left turn is a common cause of crashes.
-
9. You come upon a crash that has just happened and decide to help. Where should you stop your vehicle?
Show answer
Answer A: Well beyond the scene, completely off the road, with the hazard lights on
Stopping past the crash and off the pavement keeps you from becoming another victim and leaves the approach clear for emergency vehicles.
-
10. What are front fog lights for?
Show answer
Answer D: Adding a low, wide beam close to the car when visibility is poor
Fog lights throw a low, wide beam under the fog, which is why they are mounted low and are used only in poor visibility.
-
11. What is the minimum license revocation period for a second South Dakota DUI conviction?
Show answer
Answer C: One year
A second DUI conviction requires a revocation of at least one year, longer than the 30-day floor used for a first offense.
-
12. You and a driver coming from the opposite direction reach a four-way stop at the same time and you are both going straight ahead. What happens next?
Show answer
Answer D: Both of you may move off together, because your paths do not cross each other
Opposing vehicles that are both going straight do not cross paths, so they can move off together once the intersection is clear.
-
13. The engine dies at speed and the dashboard lights go out on a dark road. What should you do?
Show answer
Answer C: Hold the wheel firmly, steer over to the shoulder and use the hazard lights
Never switch the ignition to lock, because the steering can lock; steer to the shoulder and warn traffic with the hazard lights.
-
14. A driver ahead of you extends the left arm straight out horizontally through the window. What is being signaled?
Show answer
Answer C: A left turn
The left arm held straight out is the standard hand signal for a left turn.
-
15. You are waiting to turn left at a solid green light with no green arrow. Oncoming traffic is approaching. What should you do?
Show answer
Answer A: Yield to the oncoming traffic and turn only when there is a safe gap
A solid green light permits the left turn but does not protect it, so you must yield to oncoming vehicles and to pedestrians before turning.
-
16. Why are tall vehicles such as SUVs and vans at extra risk in sudden steering maneuvers?
Show answer
Answer B: Their higher center of gravity makes them more likely to roll over
The higher a vehicle's mass sits, the more it leans in an abrupt turn, and a sharp swerve can tip it over. Smooth, gradual steering inputs are essential in tall vehicles.
-
17. How much of a traffic lane is a motorcycle entitled to use?
Show answer
Answer D: The full width of the lane
A motorcycle is entitled to the full lane, and riders move within it to stay visible and to avoid surface hazards, so drivers should never try to share a lane with one.
-
18. How does a lap and shoulder belt protect you in a crash?
Show answer
Answer B: It holds you to the seat and spreads the force over the strong bones
The belt keeps you with the vehicle as it slows and puts the load on the hips and the chest rather than on soft tissue.
-
19. You have started to pass and you see the no-passing zone beginning ahead. What should you do?
Show answer
Answer D: Ease off, drop back and return to your own lane
A pass must be completed before the no-passing zone starts. If it will not fit, abandon it and slot back in behind.
-
20. Freeway traffic ahead of you has come to a stop. Besides braking early, how can you warn the drivers behind you?
Show answer
Answer B: By switching on the hazard lights for a few seconds
A short burst of hazard lights is a recognized way to tell following traffic that the queue ahead has stopped, and it carries much further back than brake lights. Some states restrict hazard lights on a moving vehicle, so use them only for the moment you are slowing.
-
21. Your vehicle does not have antilock brakes and you must stop quickly on a slippery road. What is the correct technique?
Show answer
Answer B: Apply the brakes firmly without locking the wheels, releasing slightly if they lock
Locked wheels slide and cannot steer. Squeezing the brakes to just short of lockup, and easing off if they lock, gives the shortest stop with control.
-
22. A yellow diamond shows two lanes narrowing into one. What does it require of a driver?
Show answer
Answer D: Adjusting speed and merging before the lane disappears
The lane ends sign gives notice that one lane will be dropped, so drivers should adjust speed and blend into the continuing lane in good time.
-
23. Why is heavy braking a poor idea while two wheels are still on a soft shoulder?
Show answer
Answer B: The two sides have different grip, so the vehicle can pull sharply
With one pair of wheels on pavement and the other on loose material, hard braking slows one side more than the other and swings the vehicle around.
-
24. A rectangular red sign with the white words WRONG WAY means that
Show answer
Answer C: the driver is already traveling against the legal flow and must not continue
The wrong way sign uses a white legend and border on red and addresses a driver who has entered a ramp or one-way roadway in the wrong direction, who should stop and turn around safely.
-
25. A highway lane is marked with a large white diamond and signed as a high-occupancy vehicle lane. Who may use it?
Show answer
Answer B: Only vehicles carrying at least the number of occupants shown on the sign, during the posted hours
The diamond marking identifies a preferential lane whose occupancy requirement and hours of operation are stated on the accompanying signs.
