1. A driver ahead of you extends the left arm straight out horizontally through the window. What is being signaled?
Show answer
Answer C: A left turn
The left arm held straight out is the standard hand signal for a left turn.
-
2. How many points suspend the license of a South Carolina driver who holds a beginner's permit, conditional license or special restricted license?
Show answer
Answer B: Six or more points
Accumulating six or more points on those credentials brings a six-month suspension, a much lower threshold than the one used for fully licensed drivers.
-
3. A truck ahead of you is spreading salt or grit on the road. What should you do?
Show answer
Answer B: Drop back so the material does not reach your car
Spreaders throw material backward and sideways, and following close means stone chips and a screen full of spray, so leave extra distance.
-
4. What do the grooves in a tire tread do on a flooded road surface?
Show answer
Answer B: They give the water a way to escape so the tread can touch the road
Tread grooves pump water out from under the tire so rubber can meet pavement. A worn tread moves less water, so hydroplaning starts sooner.
-
5. Low sun is shining onto the signal ahead and you cannot tell which light is lit. What should you do?
Show answer
Answer D: Slow down and be ready to stop until you can be sure
An unreadable signal has to be treated as one that may be red, so approach slowly enough to stop while you work out what it shows.
-
6. A white arrow painted in your lane points only to the right, and a sign above the lane shows the same movement. What must you do?
Show answer
Answer C: Turn right from that lane
Pavement arrows used with lane-use signs are regulatory, so a driver occupying that lane must make the movement shown.
-
7. Your vehicle has antilock brakes. What should you never do in an emergency stop?
Show answer
Answer A: Pump the pedal up and down
The system already releases and reapplies the brakes many times a second. Pumping the pedal interrupts it and makes the stop longer.
-
8. The curb ahead is signed as a bus stop. May you wait there with your vehicle?
Show answer
Answer C: No, the space must stay clear for buses
A bus stop must stay open so that a bus can reach the curb and let passengers on and off safely, so no other vehicle may occupy it.
-
9. A bicyclist ahead of you puts the left arm straight out to the side. What is being signaled?
Show answer
Answer B: A left turn or a move to the left
The left arm held straight out is the bicycle signal for a left turn, so hold back and give the rider room to cross toward the center.
-
10. 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.
-
11. A front tire blows out at highway speed. What should you do?
Show answer
Answer B: Hold the wheel firmly, ease off the accelerator and slow gradually before leaving the road
A blowout pulls the vehicle toward the failed tire, and hard braking or sharp steering can turn that pull into a spin, so a firm grip and gradual slowing keep the vehicle straight.
-
12. What fine range applies to a base-tier second DUI conviction in South Carolina?
Show answer
Answer A: Not less than 2,100 dollars nor more than 5,100 dollars
Section 56-5-2930(A)(2) sets the second-offense base fine between 2,100 and 5,100 dollars, alongside 5 days to 1 year imprisonment.
-
13. At an intersection where every approach carries this sign, two drivers arrive at exactly the same instant. Which of them goes first?
Show answer
Answer C: The driver on the right
Order of arrival decides who goes first, and when two vehicles arrive together the driver on the right proceeds while the other gives way.
-
14. About how far does a vehicle travel in one second at 60 mph?
Show answer
Answer A: About 88 feet
At 60 mph you cover about 88 feet every second, which is why a glance of only two or three seconds means driving the length of several vehicles blind.
-
15. Some toll facilities use signs and markings with a purple background or a purple stripe. What do they identify?
Show answer
Answer D: Lanes reserved for vehicles with an electronic toll account
Purple is assigned to lanes and ramps restricted to vehicles with a registered electronic toll collection account, so drivers without one must stay out.
-
16. Traffic in your lane is backed up and the paved shoulder looks clear. May you drive along it to get past?
Show answer
Answer C: No, the shoulder is not a travel lane
Passing must be done within the roadway; driving on the shoulder to get around traffic is prohibited and surprises anyone entering from the right.
-
17. On the Interstate system, what do the odd-numbered one and two digit routes have in common?
Show answer
Answer D: They run mainly north and south
Odd numbers are given to north and south Interstates and even numbers to east and west ones, with the numbers rising toward the north and the east.
-
18. A person with a guide dog is standing at the corner facing the street you are about to cross. What should you do?
Show answer
Answer D: Stop well back and wait quietly for them to decide
Blind pedestrians rely on engine sound to judge traffic, so stop back from the crossing and avoid the horn, which only confuses them.
-
19. It is dark, it is raining and you are towing a trailer. How should you set your following gap?
Show answer
Answer B: Add extra seconds for each condition, well beyond three
Each factor that lengthens your stopping distance or shortens your view calls for another second or more, and they add up when several occur together.
-
20. May a South Carolina driver use a mobile electronic device for turn-by-turn navigation while driving?
Show answer
Answer D: Yes, if the driver does not type on it and does not hold or support it with any part of the body
Section 56-5-3890(C)(6)(a) allows navigation, audio content, or traffic information use that does not require typing and does not involve holding the device.
-
21. Why should you avoid swinging wide to the left before making a right turn in a car?
Show answer
Answer A: Another driver may think you are turning left and try to pass on your right
Swinging left first misleads other road users about your intention and invites someone to move up on your right, exactly where you are about to go.
-
22. You want to turn left across the oncoming lane into a shopping center driveway. Who must you yield to?
Show answer
Answer B: Oncoming traffic and anyone using the sidewalk
A left turn into a driveway crosses both the oncoming lane and the sidewalk, so you give way to traffic and to pedestrians before completing it.
-
23. Which statement about standard drinks is correct?
Show answer
Answer C: A standard serving of beer, of table wine and of distilled spirits each contain about the same amount of pure alcohol
Roughly 12 ounces of regular beer, 5 ounces of table wine and 1.5 ounces of 80 proof spirits each contain about the same amount of pure alcohol, so the type of drink does not change the effect.
-
24. Why does a long downhill grade lengthen the distance you need to stop?
Show answer
Answer C: Because gravity keeps pulling the vehicle forward as you brake
On a downgrade gravity works with the vehicle and against the brakes, so the same speed needs noticeably more distance than it would on level ground.
-
25. A sign with a black legend on a fluorescent pink background is used for
Show answer
Answer A: traffic incident management
Fluorescent pink is set aside for signing that manages traffic around a crash, a spill or another unplanned incident, so it stands apart from routine work zone orange.
-
26. You are turning left from a divided highway through a median opening into a business on the other side. Who has the right of way?
Show answer
Answer C: The traffic on the roadway you are crossing
Turning through a median opening means crossing the opposite roadway, so you yield to all traffic on it before you go.
-
27. You are passing a tractor-trailer on a wet freeway and its wheels throw heavy spray. What is the best technique?
Show answer
Answer B: Increase your wipers and pass steadily without hesitating
Spray blinds you for as long as you stay beside the truck, so prepare the wipers first and then spend as little time in the spray as possible.
-
28. Visibility drops suddenly and you decide to leave the highway. What is the safest way to do it?
Show answer
Answer A: Take the next exit or a wide pull off, well clear of the traffic lanes
Get right off the traveled way, and off the shoulder too if you can, because vehicles in poor visibility often drift onto the shoulder.
-
29. In which situation should you increase your usual following distance?
Show answer
Answer B: On wet roads, at night, in fog, when towing a trailer, or when following a motorcycle
Reduced traction, reduced visibility, a heavier load and a vehicle that can stop faster than yours all require extra space to keep the same margin of safety.
-
30. What does South Carolina's minimum speed law say about driving unusually slowly?
Show answer
Answer C: It prohibits driving so slowly as to impede the normal movement of traffic, except when reduced speed is needed for safety or required by law
Section 56-5-1560(a) prohibits impeding the normal and reasonable movement of traffic by driving too slowly, with safety and legal exceptions.
