1. The green arrow protecting your turn changes to a steady yellow arrow. What is it telling you?
Show answer
Answer A: The protected turn is ending and you should prepare to stop
A steady yellow arrow warns that the arrow movement is being terminated and that a red indication will follow.
-
2. What is the PRIME position on a fuel supply valve used for?
Show answer
Answer D: To let fuel flow into the carburetor after the machine has stood unused
PRIME bypasses the normal vacuum control and lets fuel refill an empty carburetor, which helps a machine start after sitting for a long time.
-
3. A funeral procession with headlights on is crossing an intersection when your light turns green. What should you do?
Show answer
Answer A: Wait and let the whole procession go through
Most states let a funeral procession stay together once the lead vehicle has lawfully entered an intersection, and in every state you must yield to vehicles already in the intersection, so wait until the line has passed.
-
4. How does the crown of a road affect a turn made on it?
Show answer
Answer C: Turning toward the low side leaves less ground clearance for leaning
Leaning down the slope of the crown adds the slope to the lean angle, so the footrests and other parts reach the pavement sooner than they otherwise would.
-
5. Your passenger has ridden on other people's motorcycles before. What should you do before setting off?
Show answer
Answer A: Brief them anyway, because your machine and your instructions differ
Handholds, footrests, exhaust position and the signals a rider uses all vary from machine to machine, so every passenger is briefed on the machine they are about to ride on.
-
6. A driver passes this sign on an entrance ramp while merging onto a freeway. Who has priority?
Show answer
Answer B: The traffic already traveling on the freeway
The sign places the duty on the entering driver, who must adjust speed and fit into a gap without forcing through traffic to brake or swerve.
-
7. A sign at the signal reads LEFT TURN ON GREEN ARROW ONLY. The ball turns green but no arrow appears. What may you do?
Show answer
Answer C: Wait, because your turn is allowed only while the arrow is showing
The sign removes the permissive turn, so the left is legal only during the green arrow and you must wait behind the line until it appears.
-
8. You are passing a large truck on an open highway in a strong crosswind. What should you expect?
Show answer
Answer A: A push toward the truck, then a push the other way as you clear it
The truck shelters you as you go by and then releases you into the full gust, so the load on the steering changes twice during the pass.
-
9. What is wrong with riding in sneakers or sandals?
Show answer
Answer D: They come off, expose the foot and give no protection in a fall
Light footwear tears away or comes off in a crash and offers no abrasion or crush protection for the foot and ankle.
-
10. A driver has to stop for a train at this sign. How far back from the nearest rail should the vehicle be held?
Show answer
Answer C: No closer than roughly fifteen feet
A train and its load overhang the rails, so stopping no closer than about fifteen feet keeps the vehicle outside the space the train actually sweeps.
-
11. Under South Carolina's distracted driving statute, which occupational use of a mobile electronic device is exempted?
Show answer
Answer D: Transmitting or receiving data through a digital dispatch system while performing occupational duties
Section 56-5-3890(C)(4) exempts digital dispatch system use tied to occupational duties or required network testing.
-
12. A tow truck with flashing amber lights is loading a car on the shoulder ahead. How should you treat it?
Show answer
Answer B: Give it the same room as an emergency vehicle
Tow operators, utility crews and highway workers face the same danger from passing traffic, so move over or slow down for their flashing amber lights too.
-
13. You are waiting to enter a two-lane roundabout and traffic is circulating in both lanes. What must you do?
Show answer
Answer A: Yield to traffic in both circulating lanes before you enter
Every entry to a roundabout is a yield point, and at a two-lane roundabout that means giving way to vehicles in either circulating lane.
-
14. If illegally passing a stopped school bus in South Carolina causes a pedestrian's death, what happens to the driver's license upon conviction?
Show answer
Answer D: It is suspended for the length of the prison term imposed, plus one additional year
Section 56-5-2780(B) requires suspension for the term of imprisonment plus one year when the offense causes a death.
-
15. A speed limit sign carries a second panel reading TRUCKS 55. What does that panel do?
Show answer
Answer B: It sets a lower legal limit for trucks
A truck speed limit panel is regulatory, so trucks are bound by the lower figure while other traffic keeps to the main limit.
-
16. You are stopped in traffic at a red light when an ambulance comes up behind you with its siren on. What is the correct action?
Show answer
Answer D: Stay put until you can move aside legally and safely
You must not run a red light or make an unsafe move to yield; wait, then pull to the side once the way ahead lets you do it safely.
-
17. What happens to your field of vision as your speed increases?
Show answer
Answer C: It narrows, so you notice less at the sides of the road
The faster you travel, the more your useful field of view narrows toward the center, so a hazard coming from the side is seen late or missed altogether.
-
18. You must leave your vehicle beside a narrow rural road at night. What should you do?
Show answer
Answer B: Get it right off the pavement and switch on the hazard lights
A vehicle left on an unlit rural road is very hard to see, so move it completely clear of the traveled surface and mark it with the hazard lights.
-
19. You are stopped at the yield line of a roundabout when an emergency vehicle comes up behind you with lights and siren. What should you do?
Show answer
Answer A: Stay out of the roundabout and pull over to the right of your lane if there is room
Never enter a roundabout ahead of an emergency vehicle and never stop inside one; wait clear of the entry so the crew can get through.
-
20. A steady downward green arrow is displayed over a lane. What does it indicate?
Show answer
Answer C: The lane is open to traffic in your direction
A steady downward green arrow means the lane it points to is open to traffic traveling in your direction.
-
21. Where is signing of this kind normally placed along a freeway?
Show answer
Answer D: Ahead of the interchange and again at the exit, so a driver can reach the correct lane in time
Guide information for an interchange is repeated on the approach and at the ramp, because a driver who learns about the exit only at the last moment has no room left for a safe lane change.
-
22. A yellow diamond reading DIP warns a driver about
Show answer
Answer A: a short, sharp depression in the road surface
A dip is an abrupt low point that can jolt a vehicle or scrape its underside, so speed should be reduced before reaching it.
-
23. School warning signs use which background and legend colors?
Show answer
Answer A: A black legend and border on a fluorescent yellow-green background
School warning signs carry a black legend and border on a fluorescent yellow-green background, a shade chosen so they stand out from ordinary yellow warning signs.
-
24. The engine has warmed up and idles smoothly. What should be done with the choke?
Show answer
Answer C: Turn it off
A warm engine running on a rich mixture wastes fuel, runs poorly and can foul the spark plugs, so the choke is closed once it is no longer needed.
-
25. With the engine off, a rider turns the handlebars fully to the left and to the right. What is being checked?
Show answer
Answer A: That the steering moves freely and no cable is pinched or binding
Cables and wiring that catch at full lock can hold the throttle open or stiffen the steering exactly when the rider needs a tight turn.
-
26. Why is repeatedly changing lanes to work through heavy traffic a poor idea?
Show answer
Answer A: It raises the crash risk and saves almost no time
Each lane change adds a conflict with another vehicle, and in congestion the lanes move at similar average speeds, so the gain is negligible.
-
27. Your left-turn lane faces a steady green ball and oncoming traffic is heavy. What are you allowed to do?
Show answer
Answer C: Move into the intersection and turn when a safe gap appears
A green ball permits the turn but gives no priority, so you may move into the intersection and wait there for a gap in the oncoming traffic.
-
28. Does using a hands free device remove the risk of distraction?
Show answer
Answer A: No, the conversation still takes attention away from driving
Hands free equipment removes the manual part of the distraction but not the mental part, and a driver deep in conversation can look straight at a hazard without registering it.
-
29. 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.
-
30. The front tire suddenly loses air while you are riding. What should you do?
Show answer
Answer D: Hold the bars firmly, ease off the throttle and slow using the rear brake
A deflating front tire makes the steering feel heavy, so the rider keeps a straight line, avoids the affected wheel when braking and eases off the road.
