1. The green left-turn arrow ends and a steady red ball comes on for your lane, at an intersection where no turn on red is allowed. What must you do?
Show answer
Answer D: Stop and wait, because no turn is allowed while the red ball is lit
Once a red indication faces your lane and no turn on red is permitted there, the turn is over; only a vehicle already inside the intersection completes its movement.
-
2. 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.
-
3. 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.
-
4. You come upon a person riding a horse on the roadway ahead of you. What is the correct way to pass?
Show answer
Answer A: Slow down, give plenty of room and do not use the horn
Horses startle easily, and a frightened horse can throw its rider into your path. Pass slowly and wide, and avoid any sudden noise.
-
5. A school bus ahead of you has its red lights flashing and its stop arm extended. What are you required to do?
Show answer
Answer A: Stop and stay stopped until the lights stop flashing and the bus starts moving
Flashing red lights and an extended stop arm mean children are getting on or off, so traffic must stop and wait until the bus withdraws the signals and moves again.
-
6. At an intersection where turning on a red arrow is not permitted, the signal shows a red left arrow next to a steady green ball. What may you do?
Show answer
Answer D: Go straight or turn right if permitted, but not left
An arrow controls only the movement it points to, so here the red arrow stops the left turn while the green ball still allows the other movements.
-
7. A pedestrian with a white cane draws the cane back and steps away from the curb as you approach. What does that usually mean?
Show answer
Answer B: They are signaling you to go ahead and drive on
Pulling the cane in and stepping back from the curb is the customary way a blind pedestrian tells drivers to proceed.
-
8. You carry reflective warning triangles in your car. How should they be used after a breakdown?
Show answer
Answer B: Set out behind the vehicle, far enough back to warn traffic before it arrives
A warning device works only if drivers see it in time to react, so it is placed well back along the road they are traveling.
-
9. A driver stopped at a red signal wants to turn right and this sign is posted at the corner. What is permitted?
Show answer
Answer A: Nothing: the turn is barred whether the signal is red or green
The restriction works independently of the signal, so the usual permission to turn right after stopping at a red light does not exist where this sign is posted.
-
10. Which of these fits South Carolina's statutory definition of a 'mobile electronic device' for the hands-free law?
Show answer
Answer A: A cellular telephone, portable computer, GPS receiver, or electronic game
Section 56-5-3890(A) defines a mobile electronic device to include a cellular telephone, portable computer, GPS receiver, or electronic game, while expressly excluding CB radios, commercial two-way radios, and prescribed medical devices.
-
11. A person using a wheelchair is waiting to cross at a corner ahead. How should you treat that person?
Show answer
Answer B: As a pedestrian with the right of way at the crossing
A wheelchair or a mobility scooter user has the rights of a pedestrian, so yield the whole crossing and wait until the crossing is finished.
-
12. What should you do before you back out of your own driveway at home?
Show answer
Answer A: Walk around the vehicle and check behind it for children or objects
A small child, a bicycle or a toy can sit entirely inside the blind area behind a vehicle, and a walk-around is the only way to be sure it is clear.
-
13. Which sign tells you that the vehicles ahead are part of a funeral procession?
Show answer
Answer C: Headlights burning in daylight, with small flags or markers on the vehicles
Processions are normally identified by daytime headlights, hazard lights and flags or windshield markers, not by emergency lights or sirens.
-
14. A sign on a long downgrade points to a runaway vehicle ramp. What is that ramp for?
Show answer
Answer C: Trucks that have lost braking ability on the grade
A runaway ramp is an escape lane of loose material that stops a heavy vehicle whose brakes have overheated or failed, so it must always be left clear.
-
15. A small plaque mounted under this sign shows a numeral such as 2 or 3. What does that numeral report?
Show answer
Answer A: How many sets of tracks the crossing carries
The plaque states the number of tracks at that location, which is a warning that a second train may be running on another track behind the first.
-
16. What should a driver expect a short distance beyond this sign?
Show answer
Answer C: Another road crossing the one being traveled
Traffic may enter or cross from either side at the intersection ahead, so the driver should ease off, cover the brake and check both approaches.
-
17. You stop behind another vehicle at a traffic light. How much space should you leave?
Show answer
Answer D: Enough to see where its rear tires touch the pavement
Seeing the rear tires on the road leaves room to steer around the vehicle if it stalls, and gives a cushion if you are struck from behind.
-
18. A center lane is bordered by a solid yellow line on the outside and a broken yellow line on the inside, with turn arrows painted inside it. What is that lane for?
Show answer
Answer C: Left turns made by traffic traveling in either direction
That marking pattern identifies a two-way left-turn lane, which drivers approaching from both directions may use to prepare for a left turn.
-
19. Your vehicle has daytime running lights. Why should you still switch on the headlights at dusk?
Show answer
Answer B: Daytime running lights usually do not light the tail lights, so you are hard to see from behind
On many vehicles the daytime running lights illuminate only the front. Without the headlight switch on, the rear of the vehicle stays dark and the dash may still look lit.
-
20. Every signal head at an intersection is flashing red in all directions. How should you treat the intersection?
Show answer
Answer C: As an all-way stop, stopping and then going in turn
Red flashing in every direction means each approach must stop, so the intersection works exactly like an all-way stop.
-
21. You turn the wheel but the front of the vehicle keeps sliding straight ahead on a slippery road. What should you do?
Show answer
Answer C: Ease off the accelerator and reduce the steering angle until the front tires grip again
A front-wheel skid means the tires are asking for more grip than the surface can give. Less speed and less steering angle let them regain traction.
-
22. Travelling at about 55 mph on dry pavement, roughly how much room does an average car need to perceive, react and stop?
Show answer
Answer D: About 300 feet, close to the length of a football field
Reaction distance plus braking distance at 55 mph comes to roughly 300 feet on good dry pavement, and considerably more on a wet or loose surface.
-
23. You have just driven through a deep puddle and your brakes feel weak. What should you do?
Show answer
Answer D: Drive slowly while lightly applying the brakes until they dry and work normally
Wet brakes grip poorly and may pull to one side. Gentle braking at low speed generates heat that dries the pads and discs quickly.
-
24. The electric windows will not work as your vehicle sinks in water. What is the best option?
Show answer
Answer C: Break a side window with a hard, pointed object and climb out through it
Side windows are tempered glass and can be broken, while the laminated windshield cannot, and water pressure holds the doors shut.
-
25. You are about to pass a bicyclist on a narrow two-lane road. What is the correct way to do it?
Show answer
Answer A: Wait for a clear gap and move well left, giving the rider wide space
Pass a cyclist as you would a car: wait for clear road, change lane position to leave generous clearance, and return only when the rider is well behind you.
-
26. A trailer that sways badly at speed is often loaded the wrong way. What is the usual fault?
Show answer
Answer A: Too much of the load sits behind the trailer axle
Weight behind the axle lightens the hitch and lets the trailer wag the vehicle. Most of the load should sit ahead of the axle to keep weight on the hitch.
-
27. When is a child ready to use a vehicle seat belt without a booster seat?
Show answer
Answer A: When the lap belt lies across the upper thighs and the shoulder belt crosses the chest
Belt fit, not age, decides readiness. Until the child is tall enough for the lap belt to sit on the thighs and the shoulder belt on the chest, a booster is needed.
-
28. You are backing out of a space in a parking lot. Who has the right of way?
Show answer
Answer D: Traffic already moving in the lane, and pedestrians walking behind you
A driver backing out must yield to vehicles and pedestrians already using the lane, because backing is the movement with the poorest view.
-
29. Under South Carolina's implied consent warning, what is the minimum suspension for refusing the breath test?
Show answer
Answer C: Six months
A driver who refuses must be told that the privilege to drive is suspended or denied for at least six months, with the option of ending the suspension by enrolling in the Ignition Interlock Device Program.
-
30. Why are pedestrians and cyclists a special risk on unlit streets at night?
Show answer
Answer A: Dark clothing can make them invisible until they are very close
A person in dark clothing reflects almost no light and may not appear until they are inside your stopping distance, so cut your speed where people may be about.
