1. What must a driver be prepared to do at the point this sign refers to?
Show answer
Answer D: Turn left or right, because the road being traveled ends there
The road ends at another roadway, so the driver must slow, give way to traffic on the through road and turn in one direction or the other.
-
2. What is the correct relationship between air bags and seat belts?
Show answer
Answer B: Air bags are designed to work together with seat belts, not instead of them
An air bag is a supplemental restraint that cushions one impact, while the belt keeps you in position so the bag can work and protects you in rollovers and secondary impacts.
-
3. You stop at the curb on a busy street to let passengers out. What should you tell them?
Show answer
Answer A: To get out on the curb side, away from traffic
Passengers should always leave on the side away from moving traffic, which keeps both them and the door out of the travel lane.
-
4. A diamond-shaped sign is used to
Show answer
Answer A: warn of a condition on or next to the road that may call for caution
The diamond is the standard shape of the warning series, which alerts drivers to conditions that would otherwise not be obvious in time to react.
-
5. Under South Carolina law, may a driver use a hand-held phone to report a crash they just witnessed?
Show answer
Answer B: Yes, reporting an accident, emergency, or safety hazard to a public safety official is exempted
Section 56-5-3890(C)(3) exempts reporting an accident, emergency, or safety hazard to a public safety official.
-
6. You have finished parallel parking at the curb. How should the vehicle sit?
Show answer
Answer A: Close to the curb, so that it does not stick out into the traffic lane
A parked vehicle must sit close enough to the curb that it does not intrude into the path of passing traffic; the exact maximum distance is set by each state.
-
7. Why do young drivers carrying several friends face a higher crash risk?
Show answer
Answer D: Because young passengers are a strong source of distraction and pressure
Crash risk for new drivers rises with each extra young passenger, mainly through distraction and social pressure.
-
8. You are towing a trailer and turning right at an intersection. What must you allow for?
Show answer
Answer D: The trailer cuts the corner, so swing wider than usual
A trailer follows a shorter path than the towing vehicle, so its wheels track inside your line and can mount the curb unless you take the turn wide.
-
9. Along a highway the reference markers count upward as you travel. Where does the numbering normally begin?
Show answer
Answer C: At the southern or western edge of the state
Mileage numbering starts where the route enters the state from the south or the west, so rising numbers tell a driver which way they are heading.
-
10. A yellow sign reads SOFT SHOULDER. What is it telling you?
Show answer
Answer C: The shoulder may not carry the weight of a vehicle
A soft shoulder is unpaved and can let a wheel sink, so a driver who leaves the pavement there may lose control or become stuck.
-
11. How does driving on overinflated tires affect the vehicle?
Show answer
Answer D: It gives a harsher ride and a smaller contact patch
An overinflated tire bulges in the middle, so less rubber touches the road, grip suffers and the ride becomes hard. The center of the tread wears first.
-
12. 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.
-
13. 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.
-
14. What is worth carrying in the vehicle during a winter trip?
Show answer
Answer A: A blanket, a flashlight, a scraper and a small shovel
A winter kit keeps you warm and visible if you are stopped for hours, and lets you clear glass and dig the wheels out. Hot water can crack cold glass.
-
15. A United States numbered route is normally marked with
Show answer
Answer C: black numerals on a white shield
The U.S. route marker is a white shield carrying black numerals, which sets it apart at a glance from the red, white and blue Interstate shield.
-
16. Two solid white lines separate your lane from the lane beside it. What do they mean?
Show answer
Answer B: Crossing from one lane to the other is prohibited
A solid double white line marks a boundary that road users may not cross, such as the entrance to a preferential lane.
-
17. Why is a U-turn on a one-way street a problem?
Show answer
Answer A: You would end up facing the wrong way against all the traffic
Every lane of a one-way street runs the same way, so turning around leaves you driving head-on against all of the traffic.
-
18. What must a South Carolina driver do under the move-over law if changing lanes away from a stopped emergency vehicle is unsafe or impossible?
Show answer
Answer C: Maintain a safe speed for the road conditions
Section 56-5-1538(G)(2) requires maintaining a safe speed for conditions when a lane change is not possible or safe.
-
19. When should you adjust your seat, mirrors and steering wheel?
Show answer
Answer B: Before you start moving
Adjusting the driving position while moving takes your attention and often your hands away from driving. Make every adjustment while parked, every time.
-
20. A yellow pennant-shaped sign is posted on the left side of a two-lane road facing you. What is it telling you?
Show answer
Answer B: You are entering a no-passing zone and may not start a pass
The pennant is placed on the left so that it faces the driver who might pull out, and it marks the beginning of a no-passing zone.
-
21. A barricade carries a sign reading ROAD CLOSED TO THROUGH TRAFFIC. What does it permit?
Show answer
Answer B: Local access for people whose destination is on that road
This closure keeps out drivers who are only passing through while still allowing residents and deliveries to reach addresses within the closed section.
-
22. What does a flashing yellow traffic light mean?
Show answer
Answer B: Slow down and proceed with caution
A flashing yellow lets you enter the intersection cautiously after yielding to pedestrians and to conflicting traffic that is already there.
-
23. You are about to pull out of a driveway when someone on the sidewalk is walking toward it. What should you do?
Show answer
Answer D: Wait, because traffic on the sidewalk has the right-of-way
A vehicle entering the roadway from a driveway yields to people on the sidewalk as well as to traffic on the street.
-
24. A broken white line separates your lane from the lane on your right. What does it permit?
Show answer
Answer C: Changing lanes when it is safe to do so
A normal broken white line marks a boundary between lanes traveling the same way that road users may cross when it is safe.
-
25. How does South Carolina law define an 'urban district' for speed limit purposes?
Show answer
Answer A: Territory next to a street built up with structures set at intervals of less than 100 feet for a quarter mile or more
Section 56-5-1520(C) defines an urban district by that density of adjoining structures along the street.
-
26. How much should you normally reduce your speed on a road covered with packed snow compared with dry conditions?
Show answer
Answer C: By about half
Packed snow roughly doubles the distance needed to stop, so a common guideline is to cut speed by about half. On ice, slow to a crawl.
-
27. Why can a motorcycle ahead of you slow down without any warning light showing?
Show answer
Answer B: The rider may slow by downshifting or rolling off
Riders often lose speed by closing the throttle or changing down, which does not switch on the brake light, so watch the machine itself and keep back.
-
28. Four vehicles reach a four-way stop from all four directions at the same instant. How is the deadlock resolved?
Show answer
Answer C: Each driver yields to the vehicle on the right and they go one by one
Yielding to the right applies to every driver, so the group untangles itself as drivers take turns rather than moving together.
-
29. When may you stop on the shoulder of a freeway?
Show answer
Answer A: Only in an emergency, moving completely off the travel lanes and switching on your hazard lights
The freeway shoulder is reserved for emergencies and for disabled vehicles, and a vehicle stopped there must be clear of the travel lanes with hazard lights on.
-
30. A driver slows to walking pace at this sign, never stops rolling and eases into the intersection. How is that treated?
Show answer
Answer B: It is a violation, because the vehicle never came to a complete halt
What is required is a full halt with the wheels no longer turning, so slowing down, however carefully, does not satisfy it.
