Washington Road Signs Practice Test
Sharpen the skill the knowledge test leans on most: 25 questions on road sign shapes, colors, and meanings, each explained in plain English. The real DOL knowledge test has 40 questions, and you need 32 correct (80%) to pass.
Question 1 of 25
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
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. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
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. You are low on fuel on a long highway drive. Signs of which color point you to services such as gas, food, lodging, and hospitals?
Show answer & explanation
Correct answer: B. Blue signs mark motorist services, including fuel, food, lodging, rest areas, and hospitals. They let travelers plan a stop before leaving the highway. When your body or your car needs something, look for blue.
19. 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.
20. Leaving a one-way street, you see a yellow diamond sign with two vertical arrows pointing in opposite directions. What is it warning you about?
Show answer & explanation
Correct answer: A. The two-way traffic sign warns that the one-way section is ending and vehicles will now come toward you. Keep to the right and use extra care when passing. Two opposite arrows mean the road now flows both ways.
21. 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.
22. 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.
23. 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.
24. 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.
25. 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.
