  1. 1. On a rural road at dusk you pass a yellow diamond sign showing a leaping deer. What is the proper response?

    Show answer & explanation

    Correct answer: A. A deer crossing sign marks a stretch where animals often enter the road, so slow down and watch the shoulders, particularly around dawn and dusk. Deer travel in groups, so one crossing usually means more are coming. Where there's one, expect another.

  2. 2. 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.

  3. 3. 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.

  4. 4. 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.

  5. 5. A yellow diamond shows a bicycle and the words SHARE THE ROAD. What is it asking you to do?

    Show answer & explanation

    Correct answer: B. Share-the-road warnings remind you that bicyclists are legal traffic. Slow, wait for a clear gap, and pass with generous space. The sign exists because drivers otherwise squeeze bikes toward the gutter.

  6. 6. A fluorescent pink diamond is posted after a storm, showing a landslide symbol. What does the unusual color mean?

    Show answer & explanation

    Correct answer: B. Fluorescent pink is the MUTCD color for incident and emergency management, used for crashes, floods, or slides. Slow down and expect workers, debris, or a sudden close. Pink means something urgent just happened.

  7. 7. You are driving past a school crossing just as classes let out. What must you be prepared to do?

    Show answer & explanation

    Correct answer: C. Near school crossings you must slow to any posted school speed and stop whenever children or crossing guards are in the crosswalk. Kids are small, quick, and unpredictable, so extra caution is required. Expect the unexpected wherever students gather.

  8. 8. You stop at a red light planning to turn right, and a white sign beside the signal reads NO TURN ON RED. What does the sign change?

    Show answer & explanation

    Correct answer: A. Many places allow a right turn on red after a complete stop, but a NO TURN ON RED sign removes that option. It appears where crosswalks or sight lines make red-light turns risky. When posted, red simply means wait.

  9. 9. At the top of a ramp you see a square sign with a red circle and a white horizontal bar reading DO NOT ENTER. What does it mean?

    Show answer & explanation

    Correct answer: A. DO NOT ENTER marks a roadway where traffic flows toward you, such as an exit ramp or one-way street. Entering it risks a head-on crash. If you have already turned in and see WRONG WAY, pull over and turn around safely.

  10. 10. You are driving in a lane with a large white arrow painted on the pavement curving to the right. What does this marking require?

    Show answer & explanation

    Correct answer: B. A curved lane-use arrow makes that lane turn-only: follow the arrow or change lanes before the intersection. The arrows sort traffic early so drivers do not swerve at the last second. The pavement is telling you your path.

  11. 11. A yellow diamond shows a sideways wind-sock or windswept tree. What risk is ahead?

    Show answer & explanation

    Correct answer: A. Crosswind warnings mark bridges, cuts, and open plains where gusts shove vans, trucks, and empty trailers. Ease off the gas and keep both hands on the wheel. If you drive something tall, treat the sign as a speed cut.

  12. 12. 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.

  13. 13. 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.

  14. 14. Without reading any words, what does a yellow, diamond-shaped sign tell you?

    Show answer & explanation

    Correct answer: C. Yellow diamonds are warning signs: they alert you to hazards or changing conditions such as curves, intersections, or merging traffic. They advise rather than order. Shape and color alone should make you lift off the gas.

  15. 15. You approach a red circle with a slash over a U-turn arrow. What is prohibited?

    Show answer & explanation

    Correct answer: B. The slashed U-turn symbol bans reversing direction at that location, usually because sight distance or oncoming traffic makes the turn dangerous. Find a safer place — a driveway or a later intersection — to turn around.

  16. 16. A yellow diamond shows a truck tipping on a curved arrow. What should you do before the curve?

    Show answer & explanation

    Correct answer: B. The tipping-truck symbol marks a curve or ramp with a recommended lower speed for high-center vehicles — and a wise lower speed for everyone. Slow before you enter the curve, not in the middle of it.

  17. 17. You see a five-sided sign shaped like a schoolhouse outline, in fluorescent yellow-green, showing two walking figures. What does the pentagon shape identify?

    Show answer & explanation

    Correct answer: D. The pentagon shape is reserved for school signs, warning of a school zone or crossing where children may be walking. The fluorescent yellow-green color grabs attention near schools. Think of the five-sided shape as a little schoolhouse to remember it.

  18. 18. A solid white line, instead of a broken one, separates your lane from the next lane going the same way. What is it telling you?

    Show answer & explanation

    Correct answer: A. A solid white line between same-direction lanes discourages lane changes, and it appears where drifting is risky, such as near intersections and ramps. The firmer the line looks, the firmer the message: hold your lane.

  19. 19. 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.

  20. 20. 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.

  21. 21. 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.

  22. 22. A brown sign with white recreation symbols appears beside the highway. What kind of information is it giving?

    Show answer & explanation

    Correct answer: B. Brown signs point to cultural and recreation destinations. They do not change the speed limit or right-of-way. Use them to find the park; keep obeying the white and yellow signs for the rules.

  23. 23. A yellow diamond sign ahead displays a bold T symbol. What does this sign mean you will have to do soon?

    Show answer & explanation

    Correct answer: D. A T-symbol warning means your road dead-ends at a cross street, so you must slow, yield to crossing traffic, and turn left or right. The letter T shows exactly how the roads meet ahead.

  24. 24. A pentagon-shaped fluorescent yellow-green sign shows two walking children. What is it warning you about?

    Show answer & explanation

    Correct answer: B. The five-sided shape is reserved for school and school-crossing signs. Slow down and watch for children who may step off the curb without looking. Pentagon plus kids means school.

  25. 25. In a work zone, an orange sign warns of a flagger ahead. The flagger signals you to stop, even though the traffic light beyond is green. What should you do?

    Show answer & explanation

    Correct answer: C. Flaggers control traffic through work zones, and you must obey their directions even when they conflict with posted signs or signals. They can see hazards you cannot. Remember: in a work zone, the person outranks the light.
