Oregon Road Signs Practice Test

Sharpen the skill the Class C Knowledge Test leans on most: 25 questions on road sign shapes, colors, and meanings, each explained in plain English. The real DMV Class C Knowledge Test has 35 questions, and you need 28 correct (80%) to pass.

  1. 1. 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.

  2. 2. Without reading any words, what does a yellow, diamond-shaped sign always 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.

  3. 3. 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.

  4. 4. 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.

  5. 5. You pass a round yellow sign marked with a large black X and the letters R R. What is it telling you?

    Show answer & explanation

    Correct answer: A. The round yellow RXR sign is the advance warning for a railroad crossing, posted well before the tracks. It gives you time to slow, quiet distractions, and scan for trains. Round and yellow means railroad ahead, not at, the sign.

  6. 6. 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.

  7. 7. 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 no one swerves at the last second. The pavement is telling you your path.

  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. 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.

  10. 10. 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, never to overtake.

  11. 11. 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 always stop.

  12. 12. 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.

  13. 13. Which sign shape and color combination marks an interstate route?

    Show answer & explanation

    Correct answer: D. Interstate routes are marked by a shield split into a red band on top and a blue field below, with white numbers. Spotting the shield quickly helps you follow or avoid a freeway. Shield equals interstate.

  14. 14. 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.

  15. 15. 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.

  16. 16. 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.

  17. 17. On a multilane highway, white lines separate the lanes. What does the white color tell you about the traffic around you?

    Show answer & explanation

    Correct answer: B. White lines divide lanes of traffic that flow the same way, while yellow divides opposing flows. Reading line color at a glance tells you instantly where oncoming cars can be. White means with you, yellow means toward you.

  18. 18. Wide white stripes cross the pavement ahead, marking a crosswalk. What do these markings require of you as a driver?

    Show answer & explanation

    Correct answer: C. Crosswalk stripes show where pedestrians are expected to cross, and drivers must yield to people within them. You stop only when someone is crossing or a sign or signal requires it. Painted stripes mean feet ahead.

  19. 19. Orange signs, cones, and barrels suddenly appear along the highway. What does the color orange always 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.

  20. 20. A yellow diamond sign shows a truck tilted nose-down on a black slope. You are about to descend a long, steep grade. What is the proper technique?

    Show answer & explanation

    Correct answer: C. On a steep downgrade, shift to a lower gear before descending so engine braking holds your speed, and use the brakes sparingly. Constant braking overheats the pads until they fade and fail. Gears save brakes; brakes alone can quit.

  21. 21. 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.

  22. 22. 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.

  23. 23. You are driving at night and can only make out the eight-sided outline of a sign ahead. Even before reading it, what does that shape tell you to do?

    Show answer & explanation

    Correct answer: C. The octagon is reserved for stop signs alone, so the shape itself orders a full stop. This lets you obey the sign even when snow, glare, or darkness hides the word. Eight sides always equals stop.

  24. 24. 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 always means the pictured move is forbidden.

  25. 25. 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 always lose in a collision with a car. Treat the walking figure as a person already stepping off the curb.
