South Carolina Practice Test

South Carolina Practice Test (25 questions). Correct answers and explanations are noted under each question.

1. 1. What does this warning sign tell a driver to expect on the road ahead?

   

   1. A shared crossing used by pedestrians and bicyclists (correct)
   2. A school crosswalk where children cross the road
   3. A bike lane beginning along the roadway
   4. A pedestrian-only crosswalk with no bikes

   Why: The W11-15 warns of a shared crossing where pedestrians and bicyclists may enter the roadway, usually where a sidepath or multi-use trail meets the road at one point. The school-crosswalk reading is the trap because the S1-1 school crossing sign carries the same fluorescent yellow-green background, so the color reads to some drivers as 'children crossing' when it actually flags any non-motorist crossing.

2. 2. What does this Do Not Enter sign require of a driver facing it?

   

   1. Do not enter the roadway from this direction. (correct)
   2. Yield to oncoming traffic, then enter with caution.
   3. Enter only if you are a local resident or delivery driver.
   4. Enter only if driving a passenger car, not a truck.

   Why: The sign bars entry from your direction because the roadway ahead is one-way against you or is a restricted entrance; stop, back out safely, or turn around. The tempting wrong answer treats the red square like a yield, telling the driver to pause, look for oncoming, and then go if it looks clear. Yielding does not solve the problem the sign describes: any traffic on the roadway ahead is coming toward you because the roadway only runs the other way.

3. 3. A solid yellow line runs along the left side of your travel lane. What does it identify?

   

   1. The center line separating traffic moving in opposite directions.
   2. The left edge of the roadway on a divided highway, one-way street, or ramp. (correct)
   3. The right edge of the roadway on any two-lane road.
   4. A lane a driver may cross to pass when the way ahead is clear.

   Why: A solid yellow line along the left side of the travel lane marks the left edge of the roadway on a divided highway, a one-way street, or a ramp. It tells the driver they are at the left boundary of their direction of travel. The trap is the center-line answer. Yellow does separate opposing directions on an undivided two-lane road, and drivers carry that association to any yellow line without checking whether it sits down the middle or along the edge.

4. 4. What does this Flagger Ahead sign require of a driver approaching the work zone?

   

   1. Obey the hand signals of the flagger directing traffic ahead. (correct)
   2. Follow the pavement markings through the work zone until they end.
   3. Follow the traffic light at the next intersection ahead.
   4. Merge left because a lane is closed ahead of the sign.

   Why: The sign warns that a person is directing traffic in the work zone ahead, and their hand signals govern how you move through it. The trap is the answer that keeps you obeying the next traffic light; the entry is explicit that a driver takes direction from the flagger rather than from the signal or the markings when both are present.

   Source: Manual on Uniform Traffic Control Devices, sign W20-7a (Flagger Ahead (Word Message)).

5. 5. A lane is marked on the pavement with a white arrow that points both left and right. What does this require of a driver in that lane?

   

   1. Turn left or turn right; going straight is not allowed. (correct)
   2. Turn left only, since the left arrow has priority.
   3. Continue straight or turn, based on traffic conditions.
   4. Yield to oncoming traffic before choosing a direction.

   Why: A two-headed arrow marks a mandatory-turn lane: a driver in that lane must go left or right, and continuing straight is not permitted. The trap is the option that keeps straight on the table as a traffic-dependent choice, which is how a shared through-and-turn lane works. This marking is not shared. The lane is dedicated to turning, and the through movement has been ruled out before the stop bar.

6. 6. What does this yellow-green pentagon sign tell you about the road ahead?

   

   1. A school zone or school crossing is ahead; slow down and watch for children. (correct)
   2. A pedestrian crosswalk is ahead; yield to any pedestrian already in the road.
   3. You are entering a school speed zone; the reduced limit applies whenever you see this sign.
   4. A stopped school bus with flashing lights is ahead; prepare to stop until the lights go off.

   Why: The pentagon shape and fluorescent yellow-green color mark the school advance warning: a school zone or a school crossing is ahead, so slow down and watch for children stepping into the road. The trap is the plain pedestrian-crosswalk reading. Fluorescent yellow-green is also used on general pedestrian warnings, so a driver who keys on color alone and skips over the pentagon outline reaches for the crosswalk answer, when the five-sided shape is reserved for schools.

7. 7. What does this blue service sign with a white Rx symbol tell you?

   

   1. A pharmacy is available ahead. (correct)
   2. A hospital emergency department is ahead.
   3. A staffed first-aid station is ahead.
   4. A drugstore that stocks only over-the-counter remedies is ahead.

   Why: The white Rx on a blue square is the federal services sign for a pharmacy, sitting in the same blue services family as the white H for a hospital and the knife-and-fork for a food service. Drivers who read 'drugstore' as an everyday synonym for pharmacy reach for the over-the-counter-only shop, forgetting that the Rx pictograph points at a prescription counter, not at any corner store stocking aspirin.

   Source: Manual on Uniform Traffic Control Devices, sign D9-20 (Pharmacy).

8. 8. What does this Cross Road sign warn a driver about the road ahead?

   

   1. A four-way intersection ahead where cross-traffic may enter from either side. (correct)
   2. A side road ahead that joins the main road from one side only.
   3. A T-intersection ahead where the road you are on ends.
   4. A divided road ends ahead and two-way traffic will resume.

   Why: Cross Road warns that another roadway crosses straight through the road ahead, so watch for vehicles entering or crossing from either side. The pull toward the side-road option comes from mixing this diamond up with the W2-2 Side Road warning, which flags a road that meets the highway from one side only rather than a full four-way crossing.

   Source: Manual on Uniform Traffic Control Devices, sign W2-1 (Cross Road).

9. 9. What should you do when this Hill sign warns of a downgrade ahead?

   

   1. Reduce speed and shift to a lower gear before starting down. (correct)
   2. Stop completely at the crest before beginning the descent.
   3. Yield to any vehicles climbing the grade from below.
   4. Hold your speed and rely on the brakes throughout the descent.

   Why: The Hill sign warns that a steep downgrade is ahead, and the safe response is to slow down and shift to a lower gear before you start down so engine braking helps control your speed. The answer that says to hold your speed and rely on the brakes is the trap: it borrows the everyday habit of tapping the brakes on a mild slope, which lets the brakes overheat and fade on a real grade.

   Source: Manual on Uniform Traffic Control Devices, sign W7-1 (Hill).

10. 10. What does this sign tell you about the facility ahead?

    

    1. A full-service hospital with a 24-hour emergency room.
    2. Emergency medical care at a facility short of a full hospital. (correct)
    3. A highway rest area with restrooms and vending.
    4. A 24-hour pharmacy for prescription refills.

    Why: This blue sign carries a white Star of Life and marks emergency medical services ahead. It is used where medical help is available but the facility is not a full hospital, such as an ambulance station, an urgent care facility, or a trauma center. Supplemental plaques below the sign name the specific type of care offered. Drivers who reach for the hospital answer read the Star of Life as if it were the H that marks a full hospital, mixing two symbols because both belong to the same blue services family.

    Source: Manual on Uniform Traffic Control Devices, sign D9-13 (Emergency Medical Services).

11. 11. The word ONLY is painted in white in your travel lane next to a lane-use arrow. What does this require of you?

    

    1. Make the movement the arrow indicates. (correct)
    2. Yield to any driver in the adjacent lane before proceeding.
    3. Stop at the intersection before making the indicated movement.
    4. Choose either the arrow's movement or continuing straight ahead.

    Why: The ONLY legend, paired with a lane-use arrow, reserves the lane for a single movement, so a driver in that lane must turn or continue as the arrow directs. Drivers who read the arrow as one allowed movement alongside a straight-through default are the ones who miss it, because a lane marked ONLY is never applied to a lane that serves more than one movement.

    Source: Manual on Uniform Traffic Control Devices, marking 3B.21 (ONLY Pavement Legend).

12. 12. A white wheelchair symbol on a blue square is posted on a sign ahead of you. What does it tell a driver?

    

    1. The facility or parking space ahead is accessible to people with disabilities. (correct)
    2. A hospital is located ahead at the next exit.
    3. First aid or emergency medical services are available ahead.
    4. Pedestrians with limited mobility may be crossing the road ahead.

    Why: A white wheelchair on a blue square is the International Symbol of Accessibility, and it tells you the facility or parking space ahead is accessible to people with disabilities. If you treat every blue services sign as medical, you pick the hospital answer instead. Hospitals carry a white H, not a wheelchair.

    Source: Manual on Uniform Traffic Control Devices, sign D9-6 (International Symbol of Accessibility).

13. 13. What does this Added Lane sign tell a driver about the road ahead?

    

    1. A new lane joins from the right; no one is required to merge. (correct)
    2. The right lane ends ahead, so merge left before it closes.
    3. Two lanes narrow into one lane ahead.
    4. The right lane becomes an exit-only lane ahead.

    Why: The Added Lane sign says a new lane joins from the right, so through traffic can hold its lane without having to merge. The trap is the lane-ends warning: a similar yellow diamond, but one whose arrows narrow two lanes into one. Drivers who remember the shape but not which way the arrows run read this as a command to merge left, when the join happens on its own.

    Source: Manual on Uniform Traffic Control Devices, sign W4-3R (Added Lane (Right)).

14. 14. What does a white diagonal crosshatched area between an exit ramp and a freeway lane require of you?

    

    1. Drive through it only if you need to change your mind about exiting.
    2. In normal driving, stay out of the striped zone and pick a side before the point of the wedge. (correct)
    3. Treat it as a two-way separator between opposing traffic streams.
    4. Yield to any vehicle already inside the striped zone.

    Why: In normal driving, stay out of the striped zone and pick a side before the point of the wedge. The white border and diagonal stripes mark a painted gore separating same-direction traffic, so both sides of the marking carry traffic moving the same way, and the marking is not a travel or decision lane. Drivers who carry the yellow-lines-mean-opposing-traffic rule over to any zone marking they see reach for the two-way separator.

    Source: Manual on Uniform Traffic Control Devices, marking 3B.25 (White Diagonal Crosshatch (Painted Gore / Channelizing Area)).

15. 15. What does this INFO sign direct you to?

    

    1. A tourist information center or welcome center. (correct)
    2. A rest area with restrooms and vending machines.
    3. A hospital with emergency medical services.
    4. A weigh station for commercial trucks.

    Why: The blue square with the white INFO legend marks a tourist information center or welcome center, where traveler information is available. Drivers who read the blue services background as the whole meaning skip past the INFO legend and land on rest area instead.

    Source: Manual on Uniform Traffic Control Devices, sign D9-10 (Tourist Information).

16. 16. What does this sign tell a driver about the road ahead?

    

    1. A campground for tent camping is available ahead. (correct)
    2. A roadside rest area is available ahead.
    3. A picnic area with tables is available ahead.
    4. A recreational vehicle sanitary dump station is ahead.

    Why: A white tent on a blue square is a services sign that marks a campground for tent camping ahead. Drivers who pick the sanitary dump station reach for it because the reference entry lists dump stations as a related facility, but that is a separate device for a different service: this sign promises overnight tent sites.

    Source: Manual on Uniform Traffic Control Devices, sign D9-3 (Camping).

17. 17. A single broken yellow line runs down the center of a two-way roadway. What does it permit a driver to do?

    

    1. Pass slower traffic by briefly crossing into the oncoming lane when the way is clear (correct)
    2. Make left turns from the center lane in either direction of travel
    3. Drive in the oncoming lane whenever traffic in the driver's own lane is heavy
    4. Straddle the line to share the roadway with wide oncoming vehicles

    Why: A single broken yellow center line permits passing when the way is clear. A driver may briefly cross into the oncoming lane to pass slower traffic and then return. The trap is the answer that treats this line as a two-way left-turn lane; those lanes are marked with outer solid yellow lines paired with inner broken yellow lines, and a driver who learned that pattern first can reach for it here.

    Source: Manual on Uniform Traffic Control Devices, marking 3B.01 (Broken Yellow Center Line).

18. 18. What does this Turn Right sign warn a driver about the road ahead?

    

    1. A sharp right turn ahead where the road changes direction abruptly and a reduced speed is needed (correct)
    2. A gentle right curve ahead that can be rounded at the posted speed limit
    3. A right lane ending soon where drivers must merge left before it closes
    4. A right-turn-only lane ahead that through traffic must move out of

    Why: The W1-1R diamond warns of a sharp right turn: an abrupt change in roadway alignment that cannot be taken safely at the approach speed, so slow before the bend and stay in your lane through it. The trap is the choice that reads this as a gentle curve; a curve at a speed you can already hold is warned by the W1-2 series, whose arrow bends smoothly rather than turning at a right angle like the arrow on this sign.

    Source: Manual on Uniform Traffic Control Devices, sign W1-1R (Turn Right).

19. 19. What does this sign require of a driver turning left when the signal shows a solid green ball?

    

    1. Yield to oncoming traffic before completing the turn. (correct)
    2. Come to a full stop at the line, then turn when clear.
    3. Turn without yielding, because the green ball protects the turn.
    4. Wait for a green arrow; the circular green does not allow a left turn.

    Why: The placard restates the permissive left-turn rule: on a circular green ball, a driver may turn left but must first wait for a safe gap in oncoming traffic. The trap is the choice that treats the green ball as a protected turn, which is what a green arrow does; the placard is posted precisely because the ball does not protect the turn.

    Source: Manual on Uniform Traffic Control Devices, sign R10-12 (Left Turn Yield on Green).

20. 20. A center travel lane is bordered on each side by an outer solid yellow line and an inner broken yellow line. What is this lane used for?

    

    1. Left turns by traffic traveling in either direction. (correct)
    2. Passing slower vehicles when the adjacent through lane is blocked.
    3. Left turns made only by oncoming traffic from the opposite direction.
    4. Through travel to bypass congestion in the adjacent lane.

    Why: A center lane bordered by outer solid and inner broken yellow lines is a two-way left-turn lane, used by traffic from both directions only to make left turns. The trap is the choice that treats the broken yellow line as a passing line; on a two-lane road a broken yellow line does permit passing, but here the broken line only marks where vehicles may cross into the lane to turn left, and passing inside the lane is not allowed.

    Source: Manual on Uniform Traffic Control Devices, marking 3B.05 (Two-Way Left-Turn Lane).

21. 21. A solid yellow line runs down the middle of a two-way roadway, separating your lane from oncoming traffic. What does it require of you?

    

    1. Stay right of the line and do not cross it to pass slower vehicles. (correct)
    2. Pass slower vehicles ahead when the way looks clear.
    3. Cross the line at will to reach any driveway, alley, or side road.
    4. Make no left turn across the line at any point.

    Why: A solid yellow line down the center of a two-way road separates opposing traffic and closes passing on your side. You keep to the right of it and cross it only to make a permitted left turn into a driveway, alley, or side road, and only when it is safe. The trap is the choice that reads the marking as a broken yellow line and treats a clear road ahead as permission to overtake. A solid stroke has already settled the passing decision against you, regardless of how clear the road looks at the moment.

    Source: Manual on Uniform Traffic Control Devices, marking 3B.01 (Solid Yellow Center Line).

22. 22. A yellow center line has a solid line on your side and a broken line on the side used by oncoming traffic. What does this require of you?

    

    1. You are not allowed to pass another vehicle. (correct)
    2. You may pass when the way ahead is clear.
    3. Passing is allowed in either direction when safe.
    4. Passing is prohibited in both directions.

    Why: Passing is decided by which line sits on your half of the road. A solid line on your side means passing is not allowed; the broken line belongs to oncoming traffic, and their permission does not extend to you. Drivers who pick the "when the way ahead is clear" option fall back on a rural rule of thumb that any open road allows passing, without first checking which line sits on their own side.

    Source: Manual on Uniform Traffic Control Devices, marking 3B.02 (Broken-and-Solid Yellow Center Line).

23. 23. You are driving on a through street and approach an intersection with a green horizontal rectangle sign posted overhead. What does this D3-1 street name sign identify?

    

    1. The name of the cross street you are about to reach at the intersection. (correct)
    2. The name of the street you are currently traveling along right now.
    3. The remaining distance to the next town along your current route.
    4. The number of a numbered highway route you are approaching soon.

    Why: A D3-1 street name sign is a guide sign posted at an intersection, and on a through street it names the cross street you are about to reach so you know which turn is coming up. The tempting wrong pick is the choice about the street you're currently on, which mirrors how a passenger reads a street sign on a residential block as confirmation of the road the car is already on; at a through-street intersection the D3-1 label goes to the crossing roadway instead.

    Source: Manual on Uniform Traffic Control Devices, sign D3-1 (Street Name Sign).

24. 24. What does this Detour Ahead sign tell a driver about the road ahead?

    

    1. The road ahead is closed and traffic will follow a marked detour route. (correct)
    2. One lane ahead is closed but the road stays open to through traffic.
    3. A flagger is directing traffic through the work zone ahead.
    4. Workers are on or near the shoulder in the work zone ahead.

    Why: W20-2 warns that the road ahead is closed and traffic is sent around the work zone on a marked detour, so past this point you stop navigating by memory and start reading the orange DETOUR markers. The pull toward the lane-closure answer comes from drivers who've mostly met work-zone signs that shift traffic within the same road; the detour warning is used when the through route itself is shut, not narrowed.

    Source: Manual on Uniform Traffic Control Devices, sign W20-2 (Detour Ahead).

25. 25. This school crossing assembly has a downward diagonal arrow plaque mounted beneath the pentagon. What does the arrow indicate?

    

    1. The exact crosswalk where children cross the road. (correct)
    2. The direction to the nearest school building.
    3. A school zone somewhere ahead on the road.
    4. The side of the road where children walk to school.

    Why: The arrow on this assembly points to the exact crosswalk where children cross the road, which is why the assembly is posted at the crossing itself rather than in advance of it. The wrong answer to watch for is the one that treats the sign as a warning of a zone somewhere ahead; that describes the plain pentagon school sign posted before you reach the area, not this arrow-plaque version posted at the crosswalk.
