1. On loose gravel or deep fresh snow, how does an antilock system affect the stopping distance?
Show answer
Answer D: It can lengthen it, although you keep the ability to steer
On loose surfaces a locked wheel piles up a wedge of gravel or snow that helps it stop, so the antilock stop can be longer even though steering still works.
-
2. In plain words, what is understeer?
Show answer
Answer B: The vehicle keeps going straight even though the wheels are turned
Understeer means the front tires have run out of grip, so the vehicle takes a wider line than the one you steered.
-
3. The lane you are in has a right-turn-only arrow painted on the pavement. What must you do?
Show answer
Answer C: Turn right, because a lane-use arrow is a legal requirement
Lane-use arrows painted on the pavement are regulatory markings, so a driver in that lane must travel in the direction shown.
-
4. What is the main function of the guide sign series?
Show answer
Answer D: To identify routes and lead road users to their destinations
Guide signs identify routes, name destinations and give distances, so drivers can navigate without stopping to consult a map.
-
5. 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.
-
6. Why is it often safer to back into a parking space than to back out of one?
Show answer
Answer D: Because you leave the space going forward, with a clear view
Backing into the space puts the difficult maneuver where you are stopped and looking around, and lets you drive out facing the traffic and pedestrians.
-
7. Why is hard braking the wrong response to a tire blowout at speed?
Show answer
Answer C: Because it can pull the vehicle further out of line and start it spinning
With one tire gone the braking forces are uneven, so heavy braking increases the pull to one side and can spin the vehicle.
-
8. You are involved in a collision, even a minor one. What is your first legal duty?
Show answer
Answer A: Stop at or near the scene without blocking traffic more than necessary
Every driver involved in a crash must stop at the scene, and leaving before meeting that duty is a serious offense. Move the vehicles only as far as needed to clear the traffic lanes.
-
9. How should the outside mirrors be aimed to reduce your blind spots?
Show answer
Answer A: Outward, so each one covers the lane beside you rather than repeating the inside mirror
Mirrors aimed too far inward show you the same road three times and leave a large gap beside the vehicle, so aiming them outward shrinks the blind spot.
-
10. What does South Carolina law say about blocking access to an emergency scene?
Show answer
Answer A: Motor vehicles and bystanders may not block access to or exit from an emergency scene
Section 56-5-1538(C) forbids motor vehicles and bystanders from blocking access to, or exit from, an emergency scene.
-
11. A school crossing guard has returned to the curb but two children are still walking across the road. When may you go?
Show answer
Answer C: Only after the children have reached the far sidewalk
The guard leaving the road does not end your duty; you stay stopped until every child is clear of the roadway.
-
12. Which headlight setting should you use in dense fog?
Show answer
Answer B: Low beams
High beams reflect off the water droplets in fog and bounce glare back at you, while low beams aim downward and light the road without that mirror effect.
-
13. A center lane is bordered by a solid yellow line on the outside and a broken yellow line on the inside, with left-turn arrows painted in it. How may you use that lane?
Show answer
Answer A: Only to make a left turn or to prepare for one from either direction
That marking identifies a two-way left turn lane, which may only be used for left turns or to prepare for a left turn and never for travel or passing.
-
14. You are stopped at a red light waiting to turn right where the turn is allowed. Besides traffic from the left, what must you check?
Show answer
Answer D: Both crosswalks, and anyone approaching along your right side
A right turn on red crosses the crosswalk in front of you and enters the one on the cross street, and cyclists often approach along your right.
-
15. 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.
-
16. You make eye contact with a driver waiting to pull out of a side street. What should you assume?
Show answer
Answer D: The driver may still not have seen you, so stay ready to slow or stop
Drivers can look directly at you and still not register your vehicle, especially a small one. Eye contact helps, but never rely on it.
-
17. Which facility does this sign direct a traveler toward?
Show answer
Answer B: A hospital offering emergency care
This is the standard marker for medical care, used to lead a traveler to a hospital where emergency treatment is available.
-
18. A yellow diamond showing two vertical arrows, one pointing up and one pointing down, warns that
Show answer
Answer A: the road ahead carries traffic in both directions
The two-way traffic sign warns that the roadway ahead is not divided and that vehicles will be coming from the opposite direction.
-
19. How do extra passengers affect a driver, especially a new one?
Show answer
Answer A: They increase the chance of distraction and of crashes
Conversation, laughter and horseplay pull a driver's attention away from the road. Crash risk for young drivers rises with each additional passenger.
-
20. You are the second vehicle waiting to turn left on a green ball. Where should you wait?
Show answer
Answer A: Behind the stop line, until the first vehicle has actually turned
Only the lead vehicle should move into the intersection to wait; a second vehicle inside it is likely to be stranded there when the light changes.
-
21. Under South Carolina law, what must an applicant present to receive a REAL ID compliant driver's license or identification card?
Show answer
Answer B: The supporting documents the department requires to prove identity, lawful status, and residency
Section 56-1-87(B) allows the department to issue a REAL ID compliant credential only to applicants who present the required supporting documents.
-
22. You drive onto a section where the top layer has been milled off and the surface is grooved. How will it feel?
Show answer
Answer C: The steering may wander, so hold the wheel firmly and slow down
Grooves cut into the pavement tug at the tires and make the steering feel restless. A firm grip and a lower speed keep the vehicle tracking straight.
-
23. You are turning left from a one-way street onto another one-way street. Which lane should you use?
Show answer
Answer B: Turn from the far left lane into the far left lane of the new street
The general turning rule is to turn from the lane nearest the direction of the turn into the nearest lane of the new roadway, which on a one-way to one-way left turn means far left to far left.
-
24. How many passengers under 21 may a South Carolina special restricted license holder carry without an accompanying licensed adult?
Show answer
Answer C: No more than two
State law limits the holder to two passengers under 21 unless a licensed adult 21 or older is present, and the limit does not apply to family members or to students being carried to or from school.
-
25. What will the driver have to do at the point this sign refers to?
Show answer
Answer C: Slow down and let conflicting traffic go first, stopping if that is what it takes
Further along, the driver has to let conflicting traffic and pedestrians go first, reducing speed and stopping whenever that is necessary to avoid interfering with them.
-
26. What does a standard (basic) South Carolina driver's license authorize the holder to operate, beyond ordinary cars and light trucks?
Show answer
Answer B: Combinations up to 26,000 pounds gross vehicle weight, plus three-wheel motorcycles without a side car
Section 56-1-130(D) extends the basic license to combinations up to 26,000 pounds GVWR and to three-wheel motorcycles that lack a detachable side car.
-
27. You are approaching a horse and rider on a country road. What about your horn?
Show answer
Answer C: Do not sound it at all, because the noise can frighten the animal
A startled horse is dangerous to its rider and to you, so pass wide and slow and leave the horn alone.
-
28. Your navigation device tells you to turn where a road sign says the turn is closed. What should you do?
Show answer
Answer B: Follow the signs and what you can see
A device works from stored data that can be out of date, while signs and the road in front of you show the situation now, so the road wins every time.
-
29. You are traveling beside another vehicle on a multilane highway at nearly the same speed. Why is this a poor position?
Show answer
Answer B: You may be sitting in that driver's blind spot with nowhere to go if they move over
Driving alongside removes your side escape route and often puts you where the other driver cannot see you. Speed up or drop back to open space beside you.
-
30. You are traveling beside a tractor-trailer and cannot see the truck driver's face in any of the truck's mirrors. What does that tell you?
Show answer
Answer A: The truck driver probably cannot see your vehicle
Large trucks have deep blind spots on all four sides, so if the driver's face is not visible in a mirror the driver has no view of you. Move ahead or drop back until you are out of that area.
