Question 1 of 25
1. 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.
2. On a highway you pass a white regulatory sign reading MINIMUM SPEED 40. Why is that sign posted?
Show answer & explanation
Correct answer: D. A minimum speed sign requires you to travel at least the posted speed when conditions allow. Highways post it because vehicles moving far below the flow cause rear-end and lane-change crashes. Too slow can be as dangerous as too fast.
3. 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.
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. 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.
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. Many regulatory signs show a picture inside a red circle crossed by a red diagonal slash. In general, what does that design mean?
Show answer & explanation
Correct answer: D. In the MUTCD symbol system, a red circle with a diagonal slash over any picture means that action is not allowed, such as no trucks or no bicycles. It works without words, so drivers of any language understand instantly. Slash means stop doing it.
8. 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.
9. A white sign with a black arrow bending left and the word ONLY is over your lane. What does it require?
Show answer & explanation
Correct answer: B. A black arrow plus ONLY assigns that lane to one movement. If you need to go straight, change lanes before the marking. Lane-control signs win over habit; follow the arrow you are sitting under.
10. 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.
11. 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.
12. 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.
13. While driving, you notice a brown sign with white letters pointing toward a destination. What kind of place does a brown sign identify?
Show answer & explanation
Correct answer: A. Brown signs guide you to recreational and cultural spots such as parks, campgrounds, monuments, and historic sites. The earthy brown color hints at outdoor places. When you are hunting for scenery or history, follow the brown signs.
14. 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.
15. 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.
16. 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.
17. 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.
18. Two solid yellow lines run down the center of the road. What do they prohibit?
Show answer & explanation
Correct answer: D. Double solid yellow lines ban passing for traffic in both directions, because sight distance or traffic makes passing unsafe there. Crossing is generally allowed only to turn into a driveway or side road, not to overtake.
19. 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.
20. 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.
21. 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.
22. You see a white square sign showing a curved U-shaped arrow inside a red circle with a slash through it. What is prohibited?
Show answer & explanation
Correct answer: B. The slashed U-arrow bans U-turns at that location, usually because oncoming drivers cannot see you turn around in time. Continue to a spot where reversing direction is legal and safe. Red circle plus slash means the pictured move is forbidden.
23. 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.
24. 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.
25. A sign at an intersection shows a left-curving arrow inside a red circle with a diagonal slash. What must you do there?
Show answer & explanation
Correct answer: D. A slashed left arrow forbids left turns at that intersection, often because turning across oncoming traffic there causes crashes or blocks flow. Plan another route, such as continuing straight and circling the block. The slash cancels only the movement shown.
