1. A strong wind is blowing steadily across the road from your left. How should you ride?
Show answer
Answer A: Move toward the left of the lane and lean into the wind
Riding on the windward side of the lane leaves room to be pushed without leaving the lane, and a slight lean into the wind holds the line.
-
2. A friend asks for a ride and has no gear at all. What is the correct approach?
Show answer
Answer A: Provide a certified helmet, eye protection and covering clothing
A passenger hits the ground the same way the rider does, so a passenger needs the same protection: a certified helmet, eye protection, gloves, boots and covering clothing.
-
3. Which of these is announced with the same family of signs as the facility shown here?
Show answer
Answer A: A rest area for travelers
A rest area belongs to the same motorist service series, which points travelers toward facilities such as fuel, food, lodging and medical care.
-
4. You are starting from a stop on a snowy, icy street and the drive wheels begin to spin. What should you do?
Show answer
Answer C: Ease off the accelerator and start again more gently
Spinning tires polish the surface and dig in. Very gentle pressure on the accelerator, and a higher gear if you have one, gives the tires the best chance to grip.
-
5. Windblown sand has collected across the pavement at a rural intersection where you must stop. How should you handle the stop?
Show answer
Answer A: Do your braking on clean pavement before the sand, then roll across upright
Sand acts like ball bearings under the tires, so finish your braking on the clean surface ahead of it and cross the loose patch upright with no sudden inputs.
-
6. Studies of damaged helmets show that the most frequently struck area is which part?
Show answer
Answer C: The chin and jaw area, which an open face helmet leaves uncovered
The chin and face area takes a large share of helmet impacts, which is the main safety argument for a full face helmet over an open face one.
-
7. What penalty does South Carolina impose for a second distracted driving conviction within three years?
Show answer
Answer C: A 200 dollar fine that cannot be suspended plus two points on the record
A first offense is a 100 dollar fine, and a second or later offense within three years brings a 200 dollar fine that may not be suspended plus two points on the driving record.
-
8. Which effect appears as a drinker's blood alcohol level climbs well past the first drinks?
Show answer
Answer D: Loss of muscle control and steady steering
Higher levels of alcohol reach the parts of the brain that control movement, which shows up as clumsy steering, late braking and poor lane control.
-
9. Why is it risky to brake hard and steer sharply at the same moment?
Show answer
Answer C: The tires have a limited amount of grip that braking and turning must share
Each tire can deliver only so much grip, and asking it to slow the vehicle and change direction at once can exceed that limit and start a skid.
-
10. A preferential lane sign reads HOV 2+ and lists the hours it applies. During those hours, which vehicles may use the lane?
Show answer
Answer A: Vehicles carrying at least two people, counting the driver
The number on an HOV sign is the minimum number of occupants, driver included, that a vehicle must carry to use the lane while the restriction is in effect.
-
11. During a pre-ride check, what should the throttle do when it is released?
Show answer
Answer A: Snap back to the closed position on its own
A throttle that does not close by itself can leave the engine running fast when the rider expects it to slow, so a sticking cable must be repaired before riding.
-
12. Why is the road often most slippery during the first few minutes of rain after a long dry spell?
Show answer
Answer C: Oil and dust on the surface mix with the water into a slick film
Oil drippings and road dust build up on dry pavement, and the first light rain lifts them into a slippery film before heavier rain washes it away.
-
13. A United States numbered route is normally marked with
Show answer
Answer C: black numerals on a white shield
The U.S. route marker is a white shield carrying black numerals, which sets it apart at a glance from the red, white and blue Interstate shield.
-
14. A ball rolls into the street from between parked cars ahead of you. What should you expect and do?
Show answer
Answer A: Expect a child to follow it and be ready to stop
A ball is usually followed by a child who is watching the ball and not the traffic. Slow down and be prepared to stop immediately.
-
15. What do flashing yellow lights on a school bus mean?
Show answer
Answer A: The bus is about to stop to load or unload, so prepare to stop
The amber lights are the warning phase that comes before the red lights and the stop arm, so drivers should slow down and get ready to stop.
-
16. A sign beside the signal reads STOP HERE ON RED. What does it tell you?
Show answer
Answer B: Stop at that point on red, not closer to the intersection
The sign marks the required stopping point, which is set back from the corner so that turning vehicles and sight lines are not blocked.
-
17. The light ahead is green but traffic beyond the intersection is backed up. What should you do?
Show answer
Answer B: Wait behind the intersection until there is room to clear it completely
You may not enter an intersection unless you can get completely through it, because stopping inside blocks cross traffic when the signal changes.
-
18. The school bus stop ahead sign is installed where
Show answer
Answer C: a school bus stop cannot be seen from far enough away by approaching drivers
This school warning sign is used in advance of a bus stop that lacks adequate sight distance and cannot be relocated, so drivers are warned before the stopped bus comes into view.
-
19. Where should a rider with a disabled motorcycle try to stop?
Show answer
Answer D: Well clear of the traffic lanes, off the shoulder where there is room
Getting completely away from moving traffic protects the stopped rider and anyone helping, and a shoulder alone is not a safe place to work on a machine.
-
20. Why should two riders never travel side by side in the same lane?
Show answer
Answer B: Because neither rider has room to swerve if a hazard appears
Riding directly alongside another motorcycle removes the escape path each rider needs to avoid a hazard, a pothole or another vehicle.
-
21. What license does South Carolina require to operate a three-wheel motorcycle?
Show answer
Answer D: Any class of license except a Class G moped license
South Carolina does not require a motorcycle license for a three-wheel motorcycle, which may be operated with any class of license except the Class G moped license.
-
22. Once South Carolina requires a driver to file proof of financial responsibility (similar to an SR-22 filing), for how long must that proof generally be maintained before the department will waive the requirement?
Show answer
Answer A: Three years without a new qualifying conviction
Section 56-9-620 lets the department waive continued proof three years after it was required, if no new qualifying conviction occurred in that period.
-
23. A sign at the start of an exit ramp shows a speed much lower than the highway limit. What does it apply to?
Show answer
Answer C: The curve of the ramp itself, once you have left the highway
The ramp speed is set by the sharpness of the ramp curve, so you slow to it inside the deceleration lane rather than out on the highway.
-
24. You are following a tractor-trailer so closely that its rear doors fill your windshield. What is the main problem?
Show answer
Answer D: You cannot see the road ahead and the truck driver cannot see you
A truck has a deep blind spot directly behind it, and tailgating also hides everything in front of the truck from you. Drop back so you can see and be seen.
-
25. You know in advance that you will be drinking at an event. What is the most reliable plan?
Show answer
Answer A: Arrange a driver who will not drink, or another way home, before the event begins
A decision made before drinking is not affected by alcohol, while judging your own fitness afterward relies on the very ability alcohol impairs first.
-
26. A sign on a divided highway reads Keep Right Except to Pass. What does it require of you?
Show answer
Answer A: Use the left lane only to overtake, then return to a lane on the right
The left lane on such a highway is reserved for overtaking, so a driver who has finished a pass must move back to the right.
-
27. A driver extends the left arm out the window and points it downward toward the road surface. What is being signaled?
Show answer
Answer A: Slowing down or stopping
The left arm extended downward is the standard hand signal for slowing or stopping.
-
28. It is dusk and a jogger in dark clothing is running along the edge of the road. What should you do?
Show answer
Answer D: Slow down and scan the edges of the road
Dusk is the hardest light for spotting people, and dark clothing removes most of your warning, so lower speed and a careful scan of the roadsides are the answer.
-
29. Traffic is entering the freeway from a ramp ahead of you and you are in the right lane. What should you do?
Show answer
Answer C: Move to another lane if it is safe, or adjust your speed to make room
Merging drivers may have little room to adjust. Helping them in by changing lanes or easing your speed prevents conflicts even though they must legally yield to you.
-
30. Beyond this sign, cones and temporary signs lead traffic along a path that does not agree with the lines painted on the pavement. Which one must the driver follow?
Show answer
Answer C: The temporary arrangement, because it replaces the permanent layout while the work lasts
Temporary traffic control set up for the work takes precedence over the permanent signs and markings, which no longer describe how the road is being used.
