1. This sign is still standing late at night, and nobody is working. What should the driver assume?
Show answer
Answer B: The layout may still be altered, so the same care and reduced speed apply
Narrowed lanes, shifted alignments, dropped pavement edges and parked equipment remain overnight, so the hazard does not end when the crew goes home.
-
2. You want to turn left at an intersection with no signs or signals and a vehicle is coming straight toward you from the opposite direction. What must you do?
Show answer
Answer C: Yield and turn after the oncoming vehicle has passed
A driver turning left always gives way to oncoming traffic that is close enough to be a hazard, whether or not the intersection is controlled.
-
3. In a normal signal cycle, what comes after a steady red indication?
Show answer
Answer A: A green indication that starts the next movement
Yellow is a warning that a movement is ending, so it never precedes a green; a red is followed by a green or a green arrow.
-
4. Another vehicle is passing you on a two-lane road. What should you do with your speed?
Show answer
Answer A: Hold your speed or ease off slightly to shorten the pass
Speeding up strands the passing driver in the oncoming lane, while a steady speed or a slight lift lets the pass finish quickly and safely.
-
5. Red pavement markings are used on a roadway to show that
Show answer
Answer A: it must not be entered from that direction
Red markings identify a roadway that is not to be entered or used, and they also mark the pavement of truck escape ramps.
-
6. Fresh snow covers the road and earlier vehicles have left clear tracks. What line is usually best?
Show answer
Answer B: The existing tracks, where more of the tire can reach the surface
Running in the cleared tracks puts more rubber on the road surface than ploughing through loose snow, provided the tracks have not turned to polished ice.
-
7. How is the yield sign shaped and colored?
Show answer
Answer C: A downward-pointing triangle with a wide red border and a red legend on white
The yield sign is a downward-pointing equilateral triangle with a wide red border and the legend in red on a white background, an outline used for no other message.
-
8. A large truck ahead of you swings toward the left just before turning right at an intersection. What should you do?
Show answer
Answer B: Stay back and never try to move into the gap between the truck and the curb
Long vehicles need extra room and often swing wide to complete a right turn, so the space that opens on their right closes again as the trailer sweeps through it.
-
9. You are parking facing downhill on a street with a curb. Which way should the front wheels point?
Show answer
Answer A: Toward the curb, so the vehicle would roll into it if it moved
Turning the wheels toward the curb when facing downhill means a vehicle that starts to roll is stopped by the curb instead of entering the traffic lane.
-
10. How can you keep space at the sides of your vehicle in heavy traffic?
Show answer
Answer D: Drive in the gaps between the other vehicles rather than beside them
Travelling in the open spaces rather than alongside others keeps a way out open on at least one side.
-
11. Lights set into the pavement along both edges of a crosswalk start to flash yellow as you approach. What do they tell you?
Show answer
Answer D: Someone is crossing and has to be given way
In-roadway warning lights flash only when a pedestrian activates the crossing, so a flashing pattern means somebody is in or entering the crosswalk.
-
12. You are first in the queue at a red light with a marked crosswalk. Where should your vehicle stop?
Show answer
Answer A: Behind the stop line, so that the crosswalk stays clear
Stopping short of the line keeps the crosswalk usable for people on foot and keeps your vehicle out of the path of turning traffic.
-
13. You receive a phone call that you feel you must answer while driving. What is the safest way to take it?
Show answer
Answer D: Pull off the road, stop in a safe place and then answer
No call is worth a crash. Stopping in a safe location removes the distraction completely, while every other option divides your attention.
-
14. You are in the acceleration lane and the gap you were aiming for is now beside you. What is the best adjustment?
Show answer
Answer A: Change your speed a little to line up with a gap, then merge smoothly
The acceleration lane is for matching both the speed and the position of a gap, and small speed adjustments are what line the two up.
-
15. In which crash must the police always be notified?
Show answer
Answer D: Any crash in which somebody has been injured or killed, whatever the damage
Injury or death always makes a crash reportable, whatever the amount of vehicle damage or the opinions of the drivers.
-
16. You are approaching the entry of a roundabout and a pedestrian is crossing the marked crosswalk on your approach lane. What must you do?
Show answer
Answer D: Stop before the crosswalk and let the pedestrian cross
Roundabout crosswalks sit a short distance back from the yield line, and drivers must yield there before they ever reach the circulating lanes.
-
17. When may a South Dakota instruction permit holder drive with a qualified licensed adult seated beside them?
Show answer
Answer A: Between 6 a.m. and 10 p.m.
The permit allows driving from 6 a.m. to 10 p.m. with a licensed driver at least 18 years old who has one year of experience seated beside the permit holder.
-
18. What happens to a South Dakota minor's permit restrictions once the holder turns eighteen?
Show answer
Answer D: The restrictions no longer apply, though a conviction for violating them before turning eighteen can still support suspension or revocation
Reaching eighteen ends the GDL restrictions themselves, but a conviction for violating them while still a minor remains valid grounds for a suspension or revocation action.
-
19. Why should you stay out of an intersection you cannot clear, even on a green light?
Show answer
Answer B: Because you would block cross traffic when their signal turns green
A vehicle stranded in the intersection blocks the cross street when its light turns green, which stalls the whole junction and traps emergency vehicles.
-
20. A deer suddenly steps onto the road ahead of you at night. What is the safest response?
Show answer
Answer C: Brake firmly and stay in your lane rather than swerving
Swerving at speed often leads to a rollover or a head-on crash that is far worse than hitting the animal. Brake hard, hold your lane and expect more deer to follow.
-
21. Which statement best describes what the basic speed law requires of you?
Show answer
Answer C: That you never drive faster than is reasonable and safe for the conditions
Nearly every state has a basic speed law that makes the conditions the real limit: weather, traffic, light and road surface can all require a speed well below the posted number.
-
22. What is a good habit when you open the door on the traffic side of a parked car?
Show answer
Answer C: Use the hand farther from the door, which turns you to look back
Reaching across with the far hand rotates your body and brings the mirror and the road behind into view before the door moves.
-
23. Why should you avoid swinging wide to the left before making a right turn in a car?
Show answer
Answer A: Another driver may think you are turning left and try to pass on your right
Swinging left first misleads other road users about your intention and invites someone to move up on your right, exactly where you are about to go.
-
24. Which combination best reduces the chance of hydroplaning?
Show answer
Answer D: Good tread depth, correct tire pressure and lower speed in the rain
Tread channels water away, correct pressure keeps the tire's shape, and lower speed gives the tire time to push water aside. Hydroplaning can begin at surprisingly modest speeds.
-
25. You have driven at 70 mph for an hour and then exit onto a town street. What is the common risk?
Show answer
Answer B: Your sense of speed adapts, so 35 mph feels slow and you drive too fast
After a long stretch at high speed the brain adapts, so town speeds feel unnaturally slow; check the speedometer instead of trusting the feeling.
