  1. 1. At a railroad crossing you see a white X-shaped sign reading RAILROAD CROSSING, with no gates or flashing signals. How should you treat it?

    Show answer & explanation

    Correct answer: B. The crossbuck is a regulatory sign that legally works like a yield sign at the tracks. Trains cannot swerve or stop quickly, so you must give way every time. At passive crossings, your eyes and ears are the only warning system.

  2. 2. A round yellow sign with a black X and the letters RR is posted well before a crossing. What does that advance sign tell you?

    Show answer & explanation

    Correct answer: A. The circular railroad advance sign gives you time to slow, scan both ways, and be ready to stop. Do not stop on the tracks. Circle plus X means rails are coming; the crossbuck at the tracks is the actual yield-to-train sign.

  3. 3. You are in the right lane when you see a yellow diamond sign showing the right lane narrowing into the left lane. What should you do?

    Show answer & explanation

    Correct answer: B. A lane-ends sign warns your lane will disappear, so signal, match the other lane's speed, and merge before the pavement runs out. Drivers in the ending lane must yield to through traffic. Early, smooth merges prevent the last-second squeeze.

  4. 4. A white sign shows a black number 25 inside a red circle. In the US, what does that usually indicate?

    Show answer & explanation

    Correct answer: C. A red circle around a number is the international speed-limit format, used in some US areas to show kilometers per hour. Do not treat it as 25 mph unless a miles-per-hour plaque says so. Check the unit before you match the number.

  5. 5. Along a curb you see a white sign with a large letter P inside a red circle and slash. What does it tell you?

    Show answer & explanation

    Correct answer: C. A P covered by a red circle and slash is the international no-parking symbol, banning parking where the sign applies. It keeps curbs clear for visibility, hydrants, and traffic flow. Any symbol wearing the red slash is something you cannot do.

  6. 6. Small green signs with numbers appear every mile along the edge of the highway. What are these mile markers mainly used for?

    Show answer & explanation

    Correct answer: C. Mile markers count the distance across a route, letting you track your progress, judge how far your exit is, and give an exact location when you call for help. Note the nearest marker whenever trouble starts.

  7. 7. An orange sign with a black arrow reads DETOUR. What is this sign telling you?

    Show answer & explanation

    Correct answer: A. Detour signs guide you along a temporary route when the normal road is closed, often for construction or an emergency. Keep following the arrows until the detour ends, and the route will return you to your original road.

  8. 8. A yellow diamond sign ahead shows a plus symbol, like a small cross. What is this sign warning you about?

    Show answer & explanation

    Correct answer: A. The crossroad symbol warns that a full intersection is ahead, so vehicles may pull out or turn from the left or right. Slow down and scan both directions. Picture the plus sign as two roads meeting.

  9. 9. One sign shape is so important that it is reserved for a single message: STOP. Which shape is it?

    Show answer & explanation

    Correct answer: B. The eight-sided octagon belongs to the stop sign alone, so you can recognize a stop even when the face is snow-covered or faded. Count eight sides, prepare to stop. No other sign may borrow this shape.

  10. 10. A white regulatory sign reads NO TURN ON RED. You have a circular red light and want to go right. What must you do?

    Show answer & explanation

    Correct answer: B. NO TURN ON RED cancels the usual after-stop right turn. Wait for green. Cities post this where pedestrians or poor sightlines make a red-light turn dangerous. The sign overrules the general permission.

  11. 11. A yellow diamond shows two arrows pointing toward each other. What conflict is ahead?

    Show answer & explanation

    Correct answer: A. The two-way traffic warning tells you opposing cars will soon share the road, often after a divided or one-way segment. Keep right and expect headlights in the other lane. Two arrows, two directions.

  12. 12. On a two-lane road, the center line nearest your lane is broken yellow, while the line on the far side is solid yellow. When may you cross it to pass?

    Show answer & explanation

    Correct answer: C. A broken yellow line on your side means passing is permitted from your direction, but only when oncoming traffic is far enough away to pass safely. Broken means you may cross; solid means stay put.

  13. 13. You see a red-and-white triangular sign reading YIELD as you approach a traffic circle. What should you do?

    Show answer & explanation

    Correct answer: B. A yield sign tells you to slow down, check for traffic with the right-of-way, and stop only when necessary to let it pass. It keeps merges smooth without forcing pointless stops. Think of yield as give way, not a full stop every time.

  14. 14. You see a yellow pennant-shaped sign on the left side of your lane that reads NO PASSING ZONE. What should you do?

    Show answer & explanation

    Correct answer: B. The pennant is the only sign that points to the left, marking the start of a no-passing zone. Do not pull out to pass until you see a regular passing-allowed marking. Left-side pennant means stay put.

  15. 15. You reach a stop sign at an intersection that has a painted stop line. Where must you bring your vehicle to a complete stop?

    Show answer & explanation

    Correct answer: A. At a stop sign you must stop completely before the stop line; with no line, stop before the crosswalk or the intersection edge. Stopping short protects people in the crosswalk. If you need a better view, creep forward only after the full stop.

  16. 16. A yellow diamond sign shows a car with wavy skid marks trailing behind its tires. When does this warning matter most?

    Show answer & explanation

    Correct answer: D. The skidding-car sign warns that the road ahead becomes slippery when wet, so slow down and avoid sudden braking or sharp steering in rain, snow, or ice. The first minutes of rain are often the slickest, as water lifts oil off the pavement.

  17. 17. A white rectangular sign reads WRONG WAY. You have just entered a ramp. What is the safest first move?

    Show answer & explanation

    Correct answer: C. WRONG WAY means you are driving toward oncoming traffic. Stop without blocking others if you can, then leave the roadway the way you came or wait for help. Continuing forward is how head-on crashes start.

  18. 18. A horizontal black sign with a white arrow and the words ONE WAY points to the left at an intersection. What does it tell you?

    Show answer & explanation

    Correct answer: C. A ONE WAY sign means every vehicle on that street must travel in the arrow's direction. Driving against it puts you head-on into traffic. Before turning onto any city street, glance for the arrow and follow where it points.

  19. 19. A white sign with a green arrow and the word ONLY is mounted beside a traffic signal. When may you move in that direction?

    Show answer & explanation

    Correct answer: B. A signal-mounted green arrow with ONLY ties that movement to the arrow indication. Go that way when the arrow is on and the path is clear; otherwise wait. Arrows assign time as well as direction.

  20. 20. A yellow diamond sign shows a side lane curving in to join the main road ahead. You are on the main road. What does the sign mean?

    Show answer & explanation

    Correct answer: C. A merge sign warns that another roadway joins yours ahead. Entering drivers must yield, but you should adjust your speed or change lanes when safe to open a gap. Merging works best when both drivers cooperate like a zipper.

  21. 21. A diamond-shaped orange sign with black markings is posted ahead of a lane shift. What class of message is that?

    Show answer & explanation

    Correct answer: B. Orange diamonds are reserved for temporary traffic-control in work zones. They warn that the road, lanes, or workers ahead are not in their usual place. When the background turns orange, expect cones, narrowed lanes, and people on foot.

  22. 22. On a dark road you see several black-and-yellow signs, each with a single sideways V pointing to the right, spaced along the roadside. What do they mark?

    Show answer & explanation

    Correct answer: B. Chevron alignment signs outline a sharp curve, each arrowhead pointing the direction the road bends. They are placed in a series so your headlights pick up the curve's shape at night. Follow the chevrons like breadcrumbs through the turn.

  23. 23. A wide white bar is painted across your lane just before an intersection with a stop sign. Where must you stop?

    Show answer & explanation

    Correct answer: D. A stop line marks the exact place to stop: bring your vehicle to a halt before the bar, not on or past it. It keeps you clear of crosswalks and cross traffic. The bar is the boundary.

  24. 24. On a highway, you look for the way to your destination city. What kind of information do signs with a green background give you?

    Show answer & explanation

    Correct answer: D. Green guide signs point the way, listing destinations, how many miles remain, and which exits to take. They inform rather than command, so no action is required. Think of green as the color that says go this way.

  25. 25. You are driving on a road with few traffic lights when you see a yellow diamond sign showing a traffic signal symbol. Why is this sign posted, and how should you respond?

    Show answer & explanation

    Correct answer: B. Signal-ahead warnings are posted where a traffic light may surprise drivers, such as after a long stretch without one or where a hill blocks the view. Ease off the gas early so a sudden red light cannot catch you.
