Question 1 of 25
1. 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.
2. A center lane is bordered on each side by a solid yellow line with a broken yellow line inside it, and white left-turn arrows are painted for both directions. How may you use this lane?
Show answer & explanation
Correct answer: A. A two-way left-turn lane is shared by both directions for left turns only. Enter just before your turn, watch for opposing drivers using the same lane, and never travel or pass in it. Turn, do not cruise.
3. 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.
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. 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.
6. Orange signs, cones, and barrels suddenly appear along the highway. What does the color orange tell you?
Show answer & explanation
Correct answer: B. Orange is reserved for temporary traffic control, meaning construction and maintenance zones. Workers, machines, and lane shifts may appear with little warning, so slow down and stay alert. When you see orange, think people at work.
7. 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.
8. 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.
9. 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.
10. You plan to leave the freeway at exit 12. How will you know which ramp is yours?
Show answer & explanation
Correct answer: B. Freeway exits carry green guide signs topped with a numbered exit panel, and the number usually matches the nearest milepost. Match the posted number to your planned exit, then move into the exit lane early.
11. 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.
12. Which MUTCD warning-sign group includes the Deer sign W11-3?
Show answer & explanation
Correct answer: A. Official MUTCD 2009 Part 2C lists Non-Vehicular 2C.50, 51 Pedestrian, Deer, Cattle, Snowmobile, Equestrian, Wheelchair, Large Animals, Playground as W11-2,3 and related signs. Testers invent leftover dusk-group folklore. Learn that official wording, then answer the knowledge test from those words.
13. 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.
14. Ahead of a raised concrete median you see a white sign reading KEEP RIGHT with an arrow curving to the right. What should you do?
Show answer & explanation
Correct answer: A. KEEP RIGHT tells you the roadway splits around an island, median, or obstruction, and all traffic must pass on the right side. Passing left would put you into oncoming lanes. Follow the arrow around the obstacle, then continue straight.
15. Which shape is used only for yield signs, so you can recognize the sign even when you cannot read its face?
Show answer & explanation
Correct answer: D. Only yield signs use the downward-pointing triangle, just as only stop signs use the octagon. Unique shapes let drivers react from the outline alone in fog or darkness. Picture the point aiming down, telling you to back off and give way.
16. A white vertical rectangle reads SPEED LIMIT 55. What does that number legally mean?
Show answer & explanation
Correct answer: C. A white rectangular speed limit sign is a regulatory sign, so the number is the maximum lawful speed in ideal conditions. Rain, fog, or heavy traffic can make even that speed illegal. Treat the posted number as a ceiling, not a target.
17. 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.
18. 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.
19. A yellow diamond-shaped sign ahead shows a black walking figure. As you approach the marked crossing, what is the required response?
Show answer & explanation
Correct answer: B. A pedestrian crossing warning sign means people may be entering the roadway ahead, so reduce speed and prepare to stop. Pedestrians lose in a collision with a car. Treat the walking figure as a person already stepping off the curb.
20. 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.
21. A yellow line runs down the middle of a two-lane road. What does the yellow color of a center line tell you?
Show answer & explanation
Correct answer: A. Yellow center lines separate traffic moving in opposite directions, so anything across that line is oncoming. This color code works the same on every public road. Yellow in the middle means traffic meets there, not follows.
22. 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.
23. 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.
24. 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.
25. 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.
