1. The light turns yellow when your front wheels are already past the stop line inside the intersection. What should you do?
Show answer
Answer B: Keep going and clear the intersection without speeding up
Once you are legally in the intersection the safest and correct action is to continue through and clear it, without accelerating.
-
2. You are driving along a street lined with parked cars. What should you watch for?
Show answer
Answer B: Doors opening, vehicles pulling out and pedestrians stepping from between cars
Parked cars hide people and can move without warning. Keep as much space from them as you safely can and cover the brake.
-
3. You reach a one-lane bridge and a vehicle is already partway across it coming toward you. What should you do?
Show answer
Answer D: Stop before the bridge and let it come through
A vehicle already on a one-lane bridge has the right of way, and the driver who has not yet entered waits at the approach.
-
4. An angry driver is following you closely and gesturing at you. What is the safe response?
Show answer
Answer B: Drive to a police station or to a busy public place and call for help
Never stop to confront an aggressive driver and never lead one home; go somewhere public and get the police involved.
-
5. You are leaving a private driveway and entering a public street. What are you required to do?
Show answer
Answer B: Stop and yield to traffic on the street and to pedestrians on the sidewalk
A driver entering a roadway from a driveway, alley or private road must stop and yield to traffic on the roadway and to pedestrians on the sidewalk being crossed.
-
6. Besides a chemical test, what else supports an impaired driving charge?
Show answer
Answer B: The officer's observations of the driving and the driver
Weaving, slow responses, speech and balance observed by the officer are evidence in their own right, which is why a driver can be charged on behavior alone.
-
7. How should a long trip be broken up to keep the driver alert?
Show answer
Answer D: Stop for a break every couple of hours and share out the driving
Regular breaks and a change of driver are the only reliable answers to fatigue; caffeine only postpones it.
-
8. A large truck passes and hits you with a blast of wind. Which lane position leaves you the most room for error?
Show answer
Answer A: The center portion of the lane
A rider in the center portion of the lane has space on both sides to absorb the push of a wind blast without being shoved out of the lane.
-
9. On dry pavement in good weather, what is the smallest following gap you should keep?
Show answer
Answer A: About three seconds behind the vehicle ahead
Three seconds is the accepted minimum on dry roads in good visibility, and the gap should be longer in poor conditions.
-
10. How can loose spokes be found on a spoked wheel?
Show answer
Answer B: By tapping each spoke and listening for a dull sound instead of a clear ring
A correctly tensioned spoke rings when tapped, while a loose one gives a flat, dull note that stands out from the rest of the wheel.
-
11. Two vehicles meet on a steep, narrow mountain road with no room to pass. Which driver should back up?
Show answer
Answer C: The driver heading downhill, who has more control while reversing
On a narrow mountain road the vehicle facing downhill yields, because backing uphill gives better control than reversing down a grade.
-
12. When may a driver of a motor vehicle use a marked bicycle lane?
Show answer
Answer C: Only to cross it when turning or entering the road where the markings allow
A bike lane is a lane for cyclists. Motor vehicles may only cross it to enter or leave the road or to make a turn where the markings permit.
-
13. How should space management change with a passenger aboard?
Show answer
Answer B: Allow a greater following distance and wait for larger gaps in traffic
A loaded motorcycle accelerates and stops more slowly, so it needs more room ahead and bigger gaps to merge, to pass or to cross traffic.
-
14. Besides school signing, which warning signs may also use a fluorescent yellow-green background?
Show answer
Answer C: Pedestrian and bicycle warning signs
Pedestrian crossing, bicycle and playground warning signs may use either the standard yellow or the fluorescent yellow-green background, which draws extra attention where people outside vehicles are present.
-
15. Besides ambulance, police, and fire vehicles, what other vehicle type does South Carolina's move-over law cover as an 'authorized emergency vehicle'?
Show answer
Answer A: A rescue, recovery, or towing vehicle responding to a traffic incident
Section 56-5-1538(I)(1) defines an authorized emergency vehicle to include a rescue, recovery, or towing vehicle responding to a traffic incident.
-
16. The oil pressure warning light comes on while you are riding. What should you do?
Show answer
Answer D: Stop as soon as it is safe and shut the engine off
That light warns that the engine may not be receiving oil, and every extra minute of running risks destroying it.
-
17. 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.
-
18. What limits how much weight a motorcycle can carry?
Show answer
Answer A: The load limit given by the manufacturer for that machine
The manufacturer's figure covers the rider, the passenger and everything carried, and going over it overloads the tires, the brakes and the suspension.
-
19. What technical limitation does South Carolina law place on a vehicle to qualify as a 'moped' rather than a motorcycle?
Show answer
Answer B: Its engine must not exceed 50 cubic centimeters, or its electric motor must be rated no more than 1,500 watts, without a clutch or manual shifting
Section 56-1-10(26) caps a moped's gasoline engine at 50cc or its electric motor at 1,500 watts, and requires a drive system that functions without clutching or shifting by the operator.
-
20. Which of these is an early warning that you are too tired to keep driving?
Show answer
Answer C: Not remembering the last few miles you drove
Memory gaps, repeated yawning, heavy eyelids and drifting are the body signaling that sleep is winning, and they mean stop rather than push on.
-
21. How should a passenger behave through a turn?
Show answer
Answer B: Look over the operator's shoulder in the direction of the turn and avoid sudden movement
Looking over the operator's shoulder into the turn keeps the passenger aligned with the motorcycle, and avoiding sudden movement prevents unexpected changes in balance.
-
22. A bicyclist ahead of you extends the left arm out with the forearm bent upward. What does that signal mean?
Show answer
Answer A: The bicyclist intends to turn right
Bicyclists use the same hand signals as drivers: left arm straight out means left, left arm bent up means right, and left arm bent down means stop or slow.
-
23. On an overhead guide sign, the small exit number panel sits above the left-hand end rather than the right. What does that placement tell you?
Show answer
Answer A: The exit leaves from the left side of the roadway
The exit number plaque is placed on the side from which the ramp leaves, which gives advance notice of the unusual left-hand exit.
-
24. A minor drop has left the clutch lever bent, although it still works. What should be done?
Show answer
Answer B: Have the lever replaced before the motorcycle is ridden again
A bent lever has already been weakened and can break off in use, leaving the rider without that control at the worst possible moment.
-
25. 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.
-
26. 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.
-
27. Some states allow a left turn against a red light. Which movement is it?
Show answer
Answer A: A left turn from a one-way street onto another one-way street
The movement generally allowed on red is one-way to one-way, because the turn does not cross any lane of oncoming traffic; a few states also extend it to a two-way street turning onto a one-way street.
-
28. Your vehicle stalls on railroad tracks and you see a train approaching. What should you do?
Show answer
Answer D: Get everyone out and run toward the train at an angle away from the tracks
Leave the vehicle at once. Running toward the oncoming train and away from the tracks keeps you clear of the wreckage, which is thrown forward in the direction the train is moving.
-
29. What is the proper use of the horn?
Show answer
Answer C: To give a brief warning when another road user may not have seen you
The horn is a warning device meant to alert someone to your presence when a collision is possible, and using it in anger tends to escalate conflict rather than prevent crashes.
-
30. You have stopped on the shoulder of a busy freeway with a flat tire that you cannot change safely. Where should you and your passengers wait?
Show answer
Answer A: Well away from the traffic side, behind a barrier or up the bank if there is one
People struck on the shoulder are a common cause of roadside deaths, so wait away from the traffic side and behind any barrier.
