1. An orange sign reading END ROAD WORK is posted beside the highway. What does it mark?
Show answer
Answer C: The point where the work zone restrictions stop
The sign is installed at the downstream end of the temporary traffic control zone to tell drivers that normal conditions apply again.
-
2. A driver in the left lane of a freeway realizes only when level with this sign that the ramp beside it is the one they need. What is the correct action?
Show answer
Answer A: Carry on to the next interchange and turn back from there
There is no safe way back to a ramp once it has been reached from the wrong lane, so the driver keeps going to the next interchange, where the ramps are built for that movement.
-
3. 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.
-
4. Before making a right turn at an intersection, what should you check besides oncoming traffic?
Show answer
Answer B: Your right blind spot and the crosswalk, for cyclists and pedestrians
Right turns often catch a cyclist or a pedestrian coming up on the right, so check the blind spot and the crosswalk before you turn.
-
5. A sign at the curb reads Tow-Away Zone. What does it mean for you?
Show answer
Answer C: That a vehicle left there can be removed at the owner's expense
In a tow-away zone the vehicle can be removed immediately and the owner pays the towing and storage charges to get it back.
-
6. You are about to descend a long steep grade. How should you control your speed?
Show answer
Answer D: Select a lower gear before starting down and use the brakes in firm, brief applications
Engine braking in a lower gear carries most of the load down the grade, while continuous brake pressure overheats the brakes and reduces their effectiveness.
-
7. A driver passes this sign and the signal beyond it is already showing green. What is the safest response?
Show answer
Answer C: Ease off the accelerator and be ready to stop, because an indication that has been showing for a while is about to change
A signal that has been displaying the same indication for some time is close to changing, so arriving at a controlled speed with the brake covered is safer than accelerating to beat it.
-
8. An orange background with a black legend on a sign indicates
Show answer
Answer B: a temporary traffic control or work zone situation
Orange is reserved for temporary traffic control signing, so an orange sign means conditions have been altered for work or another temporary operation.
-
9. 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.
-
10. Why should you avoid parking over tall dry grass or a pile of dead leaves?
Show answer
Answer B: Because the hot exhaust can set the dry material on fire
The exhaust system stays hot for a long time after a drive and can ignite dry vegetation underneath the vehicle.
-
11. What must a South Carolina driver do first, before deciding whether to change lanes or hold speed, when approaching a stationary emergency vehicle with warning lights active?
Show answer
Answer D: Proceed with due caution and significantly reduce speed
Section 56-5-1538(G) requires proceeding with due caution and significantly reducing speed before the lane-change-or-safe-speed choice applies.
-
12. Enhanced reference location markers differ from ordinary mileposts in that they
Show answer
Answer B: carry the route number and a mileage figure to the tenth of a mile
An enhanced reference location marker adds the route designation and carries the mileage to a tenth, so the point named is far more precise than a plain milepost.
-
13. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?
Show answer
Answer A: Pull to the right edge and stop until it passes
On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.
-
14. You find yourself in a lane that must turn, you wanted to go straight, and you cannot change lanes safely. What should you do?
Show answer
Answer D: Make the required turn and find another route
Going straight from a mandatory turn lane surprises everyone around you, while a wrong turn costs only a few extra minutes.
-
15. You must stop for a train at a highway-rail crossing. Where should you stop?
Show answer
Answer B: Behind the stop line, gate or signal and well clear of the nearest rail
Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.
-
16. What is the only reliable remedy for a driver who is sleepy?
Show answer
Answer A: Sleep
Caffeine, fresh air and noise may make you feel alert for a few minutes, but they do not remove the need for sleep. Stop somewhere safe and rest.
-
17. About how much alcohol can the body eliminate per hour?
Show answer
Answer A: About one standard drink
The liver removes alcohol at a nearly fixed rate of roughly one standard drink per hour. Drinking faster than that raises the blood alcohol level, and nothing speeds the process.
-
18. You find that the road surface has turned to sheet ice. What speed is appropriate?
Show answer
Answer A: A crawl, slow enough that you could stop without braking hard
Ice can cut grip to a fraction of normal, so stopping takes many times the usual distance and only a crawl leaves any margin.
-
19. A child in the back seat unfastens a seat belt while you are on the freeway. What should you do?
Show answer
Answer A: Pull off safely and refasten the belt
Turning or reaching back takes your eyes and hands off a high speed task, so leave the freeway or use the shoulder only if there is no exit, then fix the belt.
-
20. Why does safety guidance say a child should ride in the back seat rather than in front of an active passenger airbag?
Show answer
Answer D: Because the airbag inflates with enough force to injure a small child badly
Airbags deploy at very high speed and are sized for adults, so a child seated close to one can be badly hurt by the bag itself, which is why the back seat is recommended for children.
-
21. The vehicle ahead of you has pulled out to pass a truck. May you follow it out and pass as well?
Show answer
Answer B: No, wait until it is done and judge the road for yourself
You cannot see past the vehicle ahead of you, and if it has to abort the pass there is nowhere for either of you to go.
-
22. 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.
-
23. Your vehicle has stalled on railroad tracks and no train is in sight. After getting everyone away, whom should you call first?
Show answer
Answer B: The railroad emergency number posted on the blue sign at the crossing, giving the crossing number
Every public crossing has a blue emergency notification sign with a phone number and a crossing identification number. That call lets the railroad stop or slow trains before they reach you.
-
24. You are approaching a refuse collection truck working along your street. What should you expect?
Show answer
Answer D: Workers stepping into the road around the truck
Collection crews move constantly between the truck and the curb, often from where you cannot see them, so slow right down and pass only when the whole area is clear.
-
25. How much following distance should you keep behind a motorcycle?
Show answer
Answer C: At least three to four seconds
A motorcycle can slow or stop very quickly and is easily upset by a surprise, so allow three to four seconds instead of the usual car gap.
-
26. A driver behind you on a two-lane road clearly wants to pass. Why should you not wave that driver past?
Show answer
Answer B: You cannot see the whole road ahead for them and they may rely on your signal
Waving another driver out invites them to trust your judgment of a road you cannot see well enough, and the decision to pass belongs to the driver making it.
-
27. A turn restriction sign at the corner shows a range of times below the symbol. What does that mean?
Show answer
Answer A: The turn is banned only during the hours shown on the sign
Times posted under a regulatory symbol set the period during which the restriction applies; outside those hours the movement is permitted.
-
28. A grade crossing is marked only with a crossbuck and has no lights or gates. What does the crossbuck require of you?
Show answer
Answer C: Yield to rail traffic and cross only when no train is approaching
The crossbuck requires road users to yield the right-of-way to rail traffic, so you must look and listen and be ready to stop.
-
29. You are on a one-way street with two marked lanes. May you pass a slower vehicle on the right?
Show answer
Answer A: Yes, using the right lane, provided that the move is safe and signaled
On a roadway with two or more marked lanes in your direction, moving into the free lane and going by is a normal lane change rather than an unlawful pass.
-
30. You are approaching an uncontrolled intersection on a residential street where parked cars hide the cross street. What is the correct approach?
Show answer
Answer B: Slow enough to stop and creep out until you can see
Without a sign or signal you still have to be able to yield, and you cannot yield to traffic you have not seen.
