1. An exit ramp is separated from the highway by a triangle of pavement painted with white stripes. What may you do there?
Show answer
Answer C: Nothing; keep off it and choose either the lane or the ramp
The striped area between a ramp and the through lanes is not for driving, stopping or last-second changes of direction.
-
2. You are traveling at the same speed as a vehicle in the next lane, just behind its rear door. What should you do?
Show answer
Answer B: Change your speed so that you leave that driver's blind spot
That position is the classic blind spot. Slow slightly or move ahead so the other driver can see you before deciding to change lanes.
-
3. A crossing guard steps into the roadway ahead of this sign with one hand raised. What must the driver do?
Show answer
Answer B: Stop and stay stopped until the guard waves traffic on
An adult guard is controlling traffic at that crossing, so the instruction given by that person governs and the driver waits to be released.
-
4. Some drivers believe they can multitask while driving. What does research show?
Show answer
Answer C: The brain switches rapidly between tasks and driving performance suffers
The brain does not truly do two attention-demanding tasks at once; it alternates between them, and the driving task gets less attention each time.
-
5. The vehicle in front of you has stopped and is waiting to turn left, and there is a paved shoulder to the right. May you use it to get by?
Show answer
Answer D: No, in most states a pass may not be made by leaving the paved travel lanes
Passing on the right is normally lawful only inside the marked travel lanes, and most states prohibit driving onto the shoulder to get around a turning vehicle; the few states that allow it attach strict conditions.
-
6. A warning sign showing two children on a see-saw is posted beside a residential street. What does it mean?
Show answer
Answer D: A play area lies beside the road and children may run out
The playground sign warns that children are present next to the roadway and may enter it without looking, so drivers should cover the brake and slow down.
-
7. Which shape is used for the school advance warning sign and the school crossing sign?
Show answer
Answer B: An upward-pointing pentagon
The five-sided pentagon with its point up identifies school signing, so the outline alone tells a driver that children may be present.
-
8. You are turning right off a street into a parking lot driveway that crosses a bike lane and a sidewalk. Who has the right of way?
Show answer
Answer D: Pedestrians on the sidewalk and riders in the bike lane
Turning into a driveway means crossing the paths of people who were already traveling straight, so you give way to both the bike lane and the sidewalk.
-
9. How do worn tires and worn brakes affect your ability to stop?
Show answer
Answer C: They lengthen the stopping distance, especially on a wet road
Worn tread cannot clear water and worn brakes cannot produce full force, so both stretch the distance needed to stop.
-
10. What actually lowers the amount of alcohol in a person's blood?
Show answer
Answer D: The passage of time
The body eliminates alcohol at its own steady rate, so only time reduces blood alcohol. Coffee or a cold shower may make a person feel more awake while still impaired.
-
11. A city transit bus ahead of you has stopped at the curb with its passenger door open. What does the law require of you?
Show answer
Answer D: Nothing special, but pass slowly and watch for people
The mandatory stop applies to a school bus showing red flashing lights, not to a transit bus, though a careful driver still slows for crossing passengers.
-
12. When are the hazard warning lights properly used?
Show answer
Answer A: When your vehicle is stopped or barely moving and is a hazard
Hazard lights warn that your vehicle is an obstruction; they do not authorize illegal parking and they hide your turn signals while driving.
-
13. You reach a one-lane bridge and a vehicle is already partway across it coming toward you. What should you do?
Show answer
Answer D: Stop before the bridge and let it come through
A vehicle already on a one-lane bridge has the right of way, and the driver who has not yet entered waits at the approach.
-
14. On an unlit road, about how far ahead do high beams normally let you see?
Show answer
Answer D: About 350 to 500 feet ahead of the vehicle
High beams light roughly 350 to 500 feet of road and low beams far less, which is why night speeds have to be chosen around the beam, not the limit.
-
15. What does black ice usually look like from the driver seat?
Show answer
Answer C: A patch of pavement that simply looks wet or slightly glossy
Black ice is clear, so you see the dark road through it and read it as a wet patch. In freezing weather, treat any wet looking patch as ice.
-
16. For a first DUI conviction in South Dakota, what license consequence does the court impose at minimum?
Show answer
Answer B: A revocation of at least 30 days, with discretion to extend it up to one additional year
A first DUI conviction is a Class 1 misdemeanor requiring at least a 30-day revocation, which the court may extend up to a further year.
-
17. Fog thickens until you can barely make out the vehicle ahead. What is the safest action?
Show answer
Answer A: Slow right down and, if needed, leave the road at a safe place
In heavy fog the only safe speed may be very low, and if it drops below what the road allows, the answer is to pull well clear of the traffic lanes.
-
18. It is cold and the road looks wet, but you notice the tires of vehicles ahead are throwing up no spray. What does this suggest?
Show answer
Answer B: The surface has frozen and is probably icy
Water throws spray, but ice does not. A shiny road with no spray in freezing temperatures is a strong sign of black ice, so slow down and avoid sudden inputs.
-
19. A curb lane is marked BUS ONLY 7 AM TO 9 AM. What may the driver of a car do?
Show answer
Answer A: Use the lane outside those hours
A part-time bus lane is reserved only during the posted period, and outside it the lane serves general traffic like any other.
-
20. The light ahead is green but traffic beyond the intersection is backed up. What should you do?
Show answer
Answer B: Wait behind the intersection until there is room to clear it completely
You may not enter an intersection unless you can get completely through it, because stopping inside blocks cross traffic when the signal changes.
-
21. You are slowing to turn right at an intersection and a bicyclist is riding beside your right side in a bike lane. What should you do?
Show answer
Answer D: Let the bicyclist go through the intersection before you begin the turn
Turning across the path of a bicyclist who is going straight causes the classic right-hook crash. The rider continuing straight has the right-of-way over your turn.
-
22. A train has just passed a crossing that carries more than one set of tracks. What should you do?
Show answer
Answer B: Wait until the warning devices stop and you can see clearly along every track
A passing train can hide a second one coming on another track, so wait for the signals to clear and check each track before moving.
-
23. What does South Dakota law say about wireless devices for instruction permit and restricted minor's permit holders?
Show answer
Answer D: They may not use any type of wireless communication device while driving
Holders of an instruction permit or a restricted minor's permit are barred from using any type of wireless communication device while driving on public highways.
-
24. Trees block the view along the tracks as a driver approaches this sign. What approach speed is correct?
Show answer
Answer B: Slow enough to stop before the nearest rail once a train comes into view
Where the view along the track is obstructed, the only safe speed is one that still leaves stopping distance after a train first becomes visible.
-
25. On a two-way street, where and how should you park at the curb?
Show answer
Answer C: On the right side, facing the way traffic moves
On a two-way street you must park on the right, headed in the direction of travel; parking facing traffic is prohibited.
