1. A large X with the letters R and R beside it is painted across your lane. What does it mean?
Show answer
Answer A: A railroad crossing lies a short distance ahead
The pavement marking repeats the advance warning for a grade crossing, and it is used on paved approaches where speeds are high or where gates are installed.
-
2. 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.
-
3. 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.
-
4. Your power steering fails while you are driving. What happens and what should you do?
Show answer
Answer B: Steering becomes much harder but still works, so slow down and pull off the road
Without power assistance the steering still works, but it takes much more effort, especially at low speed. Keep both hands on the wheel and get off the road.
-
5. What should you check on the hitch before towing a trailer?
Show answer
Answer B: That the coupler is locked and the safety chains are crossed underneath
The coupler must be latched and pinned, and the chains crossed under the tongue so they cradle it if the coupling lets go.
-
6. An overhead lane-use control signal shows a steady red X above your lane. What does it mean?
Show answer
Answer B: You may not use that lane and must move out of it
A steady red X means the lane below it is closed to you, while a steady yellow X is the warning to prepare to vacate the lane and a downward green arrow means the lane is open.
-
7. Which trailer lights must work before you drive away?
Show answer
Answer B: The tail lights, brake lights and turn signals
The trailer hides the vehicle lights from anyone behind, so its own tail, brake and turn signals have to work before you move.
-
8. You have stopped at a stop sign, but a parked truck blocks your view along the cross street. What should you do?
Show answer
Answer A: Creep forward slowly and stop again where you can see
When something blocks the view, a second stop closer to the intersection is the only safe way to see, and it must come before your vehicle enters the traffic lane.
-
9. You are parking on a one-way street where parking is allowed on both sides. What must still be true?
Show answer
Answer D: The vehicle must face the direction the traffic flows
Either curb may be used on a one-way street where signs allow it, but the vehicle must always be headed in the direction traffic moves.
-
10. You reach a four-way stop after another driver has already stopped there. What should you do?
Show answer
Answer D: Let the driver who stopped first proceed before you go
At a four-way stop the vehicles proceed in the order they arrived, so a driver who stopped before you goes first.
-
11. What is the usual result of driving well above the flow of traffic on a typical trip?
Show answer
Answer B: Very little time saved, with much greater risk
Signals, traffic and short distances swallow the theoretical gain, while crash risk and crash severity both climb sharply with speed.
-
12. A pedestrian waiting at a curb faces a steady upraised hand. What does that indication mean?
Show answer
Answer A: Do not start to cross in that direction
A steady upraised hand forbids entering the crosswalk, while a flashing hand only forbids starting a new crossing.
-
13. Two solid yellow lines are painted down the center of a two-way road. What do they mean?
Show answer
Answer B: Traffic in neither direction may cross them to pass
A double solid yellow line marks a no-passing zone that applies to traffic traveling in either direction.
-
14. What is wrong with steering through a turn using the palm of one hand on the wheel?
Show answer
Answer D: You have less control and cannot correct quickly if something goes wrong
One-handed palming gives poor leverage and slow response. Use hand-to-hand or hand-over-hand steering with both hands so you can react instantly.
-
15. You feel dizzy and get a headache while driving with the windows closed. What could be the cause and what should you do?
Show answer
Answer D: An exhaust leak letting carbon monoxide into the cabin, so open the windows and stop to get fresh air
Carbon monoxide is colorless and odorless, and headache, dizziness and drowsiness are early signs. Get fresh air at once and have the exhaust system inspected.
-
16. A sign showing a walking figure inside a red circle with a diagonal slash stands at the start of a bridge. What does it mean?
Show answer
Answer C: People on foot may not use that roadway
The no pedestrians sign excludes people on foot from that roadway altogether, which is common on high-speed bridges and freeways.
-
17. You have just returned to your own lane after passing. Why should you not slow down straight away?
Show answer
Answer A: The vehicle you passed is close behind and needs room to stop
Returning and then braking leaves the driver you just overtook with almost no following distance, which is how a pass turns into a rear-end collision.
-
18. A power line has fallen across your vehicle after a crash. What should you do?
Show answer
Answer C: Stay inside and wait for utility workers unless fire forces you out
The vehicle body may be energized, and touching it and the ground at the same time can be fatal. If you must leave because of fire, jump clear with both feet together and shuffle away.
-
19. You approach an intersection where the signal is flashing yellow. What should you do?
Show answer
Answer D: Slow down and cross the intersection with caution
A flashing yellow signal warns you to slow down and cross with care; it does not require a stop, but it does not give you priority either.
-
20. In most states, how far before a turn must your signal already be on in city traffic?
Show answer
Answer B: At least 100 feet, roughly the length of six or seven cars
Most states require the signal for at least 100 feet before a turn in city driving, which gives drivers behind you time to react before you slow; several require more at higher speeds.
-
21. How many points does South Carolina assess against a driver's record for failing to yield the right-of-way?
Show answer
Answer B: Four points
The point schedule in Section 56-1-720 assigns four points to failing to yield the right-of-way.
-
22. How long should a glance at a mirror or an instrument take?
Show answer
Answer A: A brief glance of about a second, returning your eyes to the road at once
Checks should be quick flicks of the eyes. At highway speed, a few seconds with your eyes off the road covers a distance long enough for a hazard to appear.
-
23. What is the main limit of stability and traction control systems?
Show answer
Answer B: They cannot create grip that the tires and the road do not have
These systems manage the grip that exists. If you enter a curve too fast for the surface, no amount of electronics will hold the vehicle on the road.
-
24. A pedestrian steps off the curb in the middle of a block where there is no crosswalk at all. What is the legal position?
Show answer
Answer A: They must yield to you, but you must still avoid a crash
A pedestrian crossing away from a crosswalk yields to vehicles, yet every driver still has a duty to use care and avoid hitting a person.
-
25. A pedestrian is crossing at a corner where no crosswalk is painted on the pavement. What is your duty?
Show answer
Answer A: Yield, because a legal crosswalk exists at the corner even without paint
Every intersection has a crosswalk whether or not it is marked, and drivers must yield to pedestrians crossing there.
-
26. A traffic signal is dark and you reach the intersection at the same moment as a vehicle on your right. Who goes first?
Show answer
Answer A: The vehicle on your right, as at any all-way stop
A dark signal is treated as an all-way stop, and the usual tie-breaker then applies: the vehicle on the right goes first.
-
27. Someone appears seriously injured after a crash. What should you generally do?
Show answer
Answer C: Call for emergency help and avoid moving the person unless there is an immediate danger such as fire
Moving an injured person can worsen spinal or internal injuries, so summon trained help and leave the person in place unless staying there is more dangerous than moving.
-
28. Where is the safest place for children under 13 to ride?
Show answer
Answer C: In the back seat
The back seat keeps children away from the force of a deploying front air bag and is farther from the most common impact area, which is why it is recommended through at least age 12.
-
29. A driver who wants to reverse direction arrives at this sign. What is allowed?
Show answer
Answer C: Going on and reversing direction only where the maneuver is permitted
The restriction removes that maneuver at that spot entirely, so the driver has to continue and turn the vehicle around at a place where it is not prohibited.
-
30. You have just passed a large truck on the freeway. Why is it dangerous to pull back in front of it and then brake for your exit?
Show answer
Answer B: A loaded truck needs much more distance to stop than a car
A fully loaded tractor-trailer can need the length of a football field or more to stop from highway speed. Cutting in and braking leaves the driver no room to avoid hitting you.
