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. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. A yellow diamond sign shows two arrows curving apart around an oval island. What is this sign telling you about the road ahead?
Show answer & explanation
Correct answer: D. The divided highway begins sign means opposing traffic will soon be separated by a median or barrier. Stay right of the divider and do not cross it. Picture the two arrows as lanes splitting around an island you must not enter.
9. 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.
10. 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.
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. Only one road sign is shaped like a sideways pennant, a triangle with its point aimed to the right. Which sign is it?
Show answer & explanation
Correct answer: A. The sideways yellow pennant is used for one message only: NO PASSING ZONE. It stands on the left side of the road where passing begins to be unsafe. One shape, one meaning makes it instantly recognizable.
13. You see a yellow diamond sign showing an arrow that bends left, then right, then left again. What does this sign tell you about the road ahead?
Show answer & explanation
Correct answer: C. A winding road sign warns of three or more curves in a row, while a single-bend arrow marks just one curve. Knowing the difference helps you hold a safe speed. Think: a wiggly arrow means the wiggles keep coming.
14. 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.
15. A yellow diamond sign shows a small red stop sign symbol with an upward arrow. What should you do when you see it?
Show answer & explanation
Correct answer: C. A stop-ahead warning is used where the actual stop sign is hidden by a curve, hill, or trees. Start braking as soon as you see it, since the real stop will appear with little warning.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. 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.
23. 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.
24. 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.
25. 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.
