1. What is the first riding effect of becoming dehydrated on a hot day?
Show answer
Answer D: Concentration and judgment fade before the rider feels very thirsty
Thirst lags behind fluid loss, so a rider can lose concentration and coordination before feeling thirsty. Drink regularly on hot rides rather than waiting.
-
2. Why should pant legs be secured and bootlaces tucked away?
Show answer
Answer A: Loose fabric and laces can tangle in the chain, the controls or a wheel
Anything hanging near the moving parts of a motorcycle can be caught and pulled in, which can trap a foot or lock the rear wheel.
-
3. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?
Show answer
Answer B: In the first traffic lane to the left of the bike lane
A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.
-
4. Why does a rider on an unfaired motorcycle tire faster on a long highway ride than a driver would?
Show answer
Answer A: Constant wind pressure and noise drain energy hour after hour
Fighting wind pressure and enduring wind noise for hours is physically tiring, which is why wind protection and regular breaks matter on long rides.
-
5. Alcohol is classified as which kind of drug?
Show answer
Answer B: A depressant that slows the central nervous system
As a depressant, alcohol slows the brain and nervous system, which lengthens reaction time and dulls the coordination that driving depends on.
-
6. How should braking and swerving be combined?
Show answer
Answer C: Brake before or after the swerve, never during it
Traction can be spent on turning or on braking, and asking for both at once during a swerve is very likely to cause a skid.
-
7. What three things does South Carolina law say the required 'control' of a vehicle near an emergency scene is meant to accomplish?
Show answer
Answer A: Prevent a collision, prevent injury to people or property, and avoid interfering with emergency personnel or vehicles
Section 56-5-1538(F) ties the required control to preventing collisions and injury and to avoiding interference with emergency personnel or vehicle operations.
-
8. Why does a motorcycle with a manual fuel supply valve have an OFF position?
Show answer
Answer A: It stops fuel reaching the engine while the machine is parked
Shutting the valve keeps fuel from seeping past the carburetor into the engine or onto the ground while the motorcycle stands unused.
-
9. Where is a road work ahead sign placed?
Show answer
Answer B: In advance of the work space or detour, so drivers are warned before reaching it
Advance warning signs are placed upstream of the work space or detour so that drivers have time to slow down and change lanes before reaching the activity.
-
10. What fine range applies in South Carolina to a driver who commits highway worker endangerment in a work zone but causes no physical injury?
Show answer
Answer A: Not less than 500 dollars nor more than 1,000 dollars
Section 56-5-1535(B)(1) fines a no-injury highway worker endangerment violation between 500 and 1,000 dollars.
-
11. You are traveling at 55 mph and see a vehicle ahead moving at about 15 mph. What is the hazard?
Show answer
Answer A: You reach it far sooner than you expect
At a 40 mph difference you cover the gap in a few seconds, which is why drivers strike slow vehicles they saw in plenty of time.
-
12. A yellow sign reading DEAD END is posted at the entrance to a street. What does it mean?
Show answer
Answer D: The street ends and there is no way through
A dead end street stops at its far end, so a driver who enters must come back out the same way.
-
13. You want to pass on a two-lane road where several people are walking on the narrow shoulder ahead. What should you consider?
Show answer
Answer D: There is no escape room if the pass goes wrong, so wait for a better place
A pass depends on having somewhere to go if it goes wrong, and a shoulder occupied by pedestrians removes that option for both vehicles.
-
14. Which shape is used for the school advance warning sign and the school crossing sign?
Show answer
Answer B: An upward-pointing pentagon
The five-sided pentagon with its point up identifies school signing, so the outline alone tells a driver that children may be present.
-
15. The center line beside your lane is solid yellow while the opposite side has a broken yellow line. What does this mean?
Show answer
Answer D: You may not pass, but traffic in the other direction may
A solid yellow line on your side of the center marks a no-passing zone for your direction only, while the broken line grants the opposing direction a passing zone.
-
16. You are turning left out of a driveway onto a busy two-way street. What must you do?
Show answer
Answer D: Wait for a gap in both directions before you start to move
The turn crosses one direction of traffic and joins the other, so you need a gap in both before leaving the driveway rather than stopping across a lane.
-
17. The vehicle in front of you has stopped and is waiting to turn left, and there is a paved shoulder to the right. May you use it to get by?
Show answer
Answer D: No, in most states a pass may not be made by leaving the paved travel lanes
Passing on the right is normally lawful only inside the marked travel lanes, and most states prohibit driving onto the shoulder to get around a turning vehicle; the few states that allow it attach strict conditions.
-
18. 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.
-
19. What most often leads to an engine seizure on a motorcycle?
Show answer
Answer A: Loss of engine oil or coolant, so the moving parts overheat and grip
Seizure is normally a lubrication or cooling failure, which is why oil level and coolant are part of every pre-ride check and why a rising temperature reading deserves attention.
-
20. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?
Show answer
Answer C: At the opening before the solid line begins
The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.
-
21. 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.
-
22. The red lights on a stopped school bus go out and the bus begins to move away. What should you do?
Show answer
Answer B: Move off slowly and keep watching for children near the road
Children who have just left the bus may still be near the roadway or crossing behind it, so pull away gently and keep looking for them.
-
23. At what alcohol concentration does South Carolina charge a driver with driving with an unlawful alcohol concentration?
Show answer
Answer B: 0.08 percent or more
State law makes it unlawful to drive with an alcohol concentration of eight one-hundredths of one percent or more, separately from the driving under the influence offense.
-
24. A school sign combined with an AHEAD plaque, or with a plaque giving a distance in feet, forms an assembly that
Show answer
Answer B: warns of a school crossing located further along the road
The school advance crossing assembly is placed before the crosswalk to give drivers notice, while a different assembly marks the crossing itself.
-
25. The car ahead of you slows down for no reason that you can see. Should you pull out and pass?
Show answer
Answer B: No, find out why it is slowing before you commit to the other lane
A driver usually slows for something, such as a turn, a hazard or a pedestrian, and that something is often exactly where your pass would take you.
-
26. Below a speed limit sign is a smaller panel with white numbers on a black background and the word NIGHT. What does it show?
Show answer
Answer D: The limit that applies after dark
A night speed limit panel sets a separate legal maximum for the hours of darkness, and its reversed colors mark it as the night figure.
-
27. Driving at night you notice that the raised markers along the line beside you are throwing back red light. What does that tell you?
Show answer
Answer C: You are facing traffic and must get off that roadway
Red retroreflection is shown only toward traffic that should not be there, so a red return means the vehicle is heading the wrong way.
-
28. About how far ahead do low beam headlights let you see on a dark road?
Show answer
Answer B: About 250 feet
Low beams light roughly 250 feet of road, and high beams roughly 350 to 500 feet, which sets the limit on a safe night speed.
-
29. A yellow diamond showing a bicycle is posted on a rural road. What should a driver expect?
Show answer
Answer A: Bicyclists crossing or riding along the roadway there
The bicycle warning sign is used where a bikeway crosses the road or where riders are likely to be in the traffic lanes, so drivers should look carefully and pass wide.
-
30. A driver is following you far too closely and you have a turn coming up. How should you slow down for it?
Show answer
Answer B: Signal early and slow gradually well before the turn
Early signals and gentle braking give a tailgater the time and distance they have failed to leave for themselves.
