1. You are in the middle lane of a one-way street with three lanes when a police car approaches from behind with lights and siren. What should you do?
Show answer
Answer C: Pull to the nearest curb and stop clear of the lanes
On a one-way street you clear to whichever curb is closest, so the emergency vehicle gets a clear path down the open lanes.
-
2. You are passing a crash on the other side of a divided highway. What should you do?
Show answer
Answer D: Keep your eyes on your own lane and the traffic around you
Staring at a crash scene, often called rubbernecking, causes sudden slowing and secondary collisions. Your attention belongs on the traffic in front of you.
-
3. How do stimulant drugs such as amphetamines or cocaine typically affect driving?
Show answer
Answer D: They can make the driver overconfident and more willing to take risks
Stimulants create a false sense of alertness and encourage aggressive, risky driving. When they wear off, sudden fatigue can follow.
-
4. On dry pavement in good weather, what is the smallest following gap you should keep?
Show answer
Answer A: About three seconds behind the vehicle ahead
Three seconds is the accepted minimum on dry roads in good visibility, and the gap should be longer in poor conditions.
-
5. Why would this sign be installed on an approach?
Show answer
Answer B: Because the signal cannot be seen from far enough back for a driver to react in time
Advance notice of a signal is used where a crest, a curve, trees or a building keep the signal heads out of view until a driver is already too close to stop comfortably.
-
6. Loose gravel has been swept into the middle of your lane on a downhill bend. Which controls are affected most?
Show answer
Answer D: Steering and braking, since the loose stones roll under the tires
Gravel rolls between rubber and pavement, so the tires can neither turn the vehicle nor slow it as they would on a clean surface.
-
7. Where are signs of this kind placed at an intersection?
Show answer
Answer C: At the near right and far left corners, facing drivers on the intersecting street
They are installed at the corners of the intersecting street so that a driver about to turn in sees the restriction before committing to the turn.
-
8. At which location is this sign normally installed?
Show answer
Answer D: Facing traffic that could turn into a one-way roadway or ramp against the flow
It is posted where a driver could otherwise enter a ramp or a one-way roadway from the wrong end, so it faces exactly the traffic that has to be kept out.
-
9. You are driving through patchy fog on a highway. What should you be ready for?
Show answer
Answer B: Sudden dense banks where visibility drops within a few car lengths
Patchy fog can go from clear to nearly blind in a moment, so keep your speed low enough that a sudden bank does not leave you without room.
-
10. At a railroad crossing with no gates and no flashing lights, the crossbuck is normally combined with which sign?
Show answer
Answer C: A yield sign, or a stop sign where an engineering study calls for one
At a passive crossing the crossbuck forms an assembly with a yield sign, or with a stop sign when an engineering study or engineering judgment supports it, so the driver knows who must give way to the train.
-
11. The trailer you are towing begins to sway from side to side at highway speed. What should you do?
Show answer
Answer D: Ease off the accelerator, hold the wheel steady and let the speed drop
Sway grows with speed and with sudden inputs. Reducing speed gently while keeping the steering steady lets the trailer settle behind you.
-
12. You are about to pull out from a stop sign. Which scanning habit is correct?
Show answer
Answer A: Look to the left, then to the right, then to the left again before moving
Traffic from the left reaches you first, and a second look left catches anything that arrived while you were looking right.
-
13. May you park at the curb immediately next to a railroad crossing?
Show answer
Answer A: No, you must leave the crossing and its approach clear
Parking beside a crossing hides the tracks and the signals from approaching drivers and leaves no room for a vehicle that has to clear the rails.
-
14. 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.
-
15. You realize your tires are running on ice. Which set of inputs is safest?
Show answer
Answer C: Gentle steering, no sudden braking, and no sudden acceleration
Whatever grip is left is used up at once by any sudden input, so every movement of wheel, brake and accelerator must be slow and small.
-
16. A yellow horizontal rectangular sign showing one large arrow pointing left or right, facing traffic on the far side of a sharp bend, tells the driver
Show answer
Answer C: which way the roadway turns at that point
The large arrow sign is mounted on the outside of a sharp change in alignment so that a driver approaching head on immediately sees which way the road goes.
-
17. While you wait for the ambulance at a crash, what is the most useful help you can give?
Show answer
Answer C: Keep the person still and warm, and press down firmly on any heavy bleeding
Keeping an injured person still and warm and controlling bleeding are among the few things a bystander can safely do.
-
18. How much clear road do driver manuals say you need before starting a pass at highway speed on a two-lane road?
Show answer
Answer C: Enough to complete the pass and return, roughly ten to twelve seconds of travel
At highway speed the whole maneuver of pulling out, overtaking and returning takes roughly ten to twelve seconds, and every foot of that has to be visible before you start.
-
19. How much must a South Carolina driver pay to reinstate a license after a suspension or revocation, in addition to any other requirement?
Show answer
Answer B: 100 dollars for each unreinstated suspension
Section 56-1-390(1) charges a 100 dollar reinstatement fee for each suspension that has not yet been reinstated.
-
20. Two left-turn lanes are available and you must turn right again a short distance after the turn. Which of the two should you use?
Show answer
Answer D: The right one, so you finish nearer the right side of the new street
Each turn lane feeds the matching lane of the new street, so choosing the right-hand of the two left-turn lanes leaves you closer to the side you will need.
-
21. What is the basic rule for entering a roundabout?
Show answer
Answer B: Traffic already circulating goes first, and you wait for a gap
Entering traffic yields to vehicles already going around the circle, which is what keeps a roundabout moving instead of locking up.
-
22. A short driver cannot get ten inches between the chest and the steering wheel airbag. What is the answer?
Show answer
Answer D: Move the seat back and tilt the wheel downward, or fit pedal extenders
Distance from the airbag is gained by moving the seat back and aiming the wheel at the chest, using pedal extenders if the pedals are then out of reach.
-
23. A mixed drink is made with two shots of spirits. How much alcohol is that?
Show answer
Answer C: About two standard drinks
A standard drink is a fixed amount of pure alcohol, so a glass poured with two measures counts as two drinks however it is served.
-
24. 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.
-
25. You correct a rear wheel skid and the back of the vehicle swings the other way. Why?
Show answer
Answer D: You steered too far, so be ready to correct back the other way
Over correcting sends the tail past straight and starts a second skid the opposite way. Steer smoothly and be ready to unwind the correction.
-
26. Why should you dim the instrument panel and keep interior lights off when driving at night?
Show answer
Answer C: Bright light inside the vehicle reduces your ability to see the dark road ahead
Your eyes adapt to the brightest light they see. A bright cabin keeps them from adjusting to the darkness outside and creates reflections on the windshield.
-
27. A streetcar is coming along tracks in the middle of the street as you wait to turn across them. What should you do?
Show answer
Answer A: Let the streetcar pass before you cross the tracks
Rail vehicles cannot steer around you and need a long distance to stop, so drivers yield to a streetcar or light rail train.
-
28. How does eating a large meal before drinking affect impairment?
Show answer
Answer D: It slows absorption but the alcohol still reaches the blood and impairs you
Food delays how quickly alcohol enters the bloodstream, which can make the peak arrive later, but all of the alcohol is eventually absorbed.
-
29. Your headlights suddenly go out while you are driving at night. What should you do?
Show answer
Answer A: Try the dimmer switch and the headlight switch, turn on the hazard lights and pull off the road
Switching between high and low beams or cycling the light switch sometimes restores the lights. If not, use the hazard and parking lights to get off the road safely.
-
30. Why should you set the parking brake even when an automatic transmission is in Park?
Show answer
Answer B: Because it takes the strain off the transmission and holds the vehicle
The parking pawl is a small part carrying the whole vehicle; the parking brake shares that load and holds the vehicle if the pawl fails.
