Wyoming Road Signs Practice Test
Sharpen the skill the Written test, delivered on Wyoming's automated testing system (also called the knowledge test) leans on most: 25 questions on road sign shapes, colors, and meanings, each explained in plain English. You need 80% correct to pass the real WYDOT Written test, delivered on Wyoming's automated testing system (also called the knowledge test).
Question 1 of 25
1. 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.
2. You have been driving through a no-passing zone. Which sign tells you the zone has ended and passing is allowed again when safe?
Show answer & explanation
Correct answer: D. A white regulatory sign reading PASS WITH CARE marks the end of a no-passing zone. You may pass again, but only when the road ahead is clear. The word CARE reminds you the choice is still yours to judge.
3. A freeway lane is marked with white diamond symbols, and a sign says the lane is for high-occupancy vehicles (HOV 2+). Who may drive in it during the posted hours?
Show answer & explanation
Correct answer: B. Diamond-marked HOV lanes are reserved for vehicles meeting the posted occupancy, like two or more people in an HOV 2+ lane. Rewarding shared rides moves more people in fewer cars. The diamond means special rules, so read the sign before entering.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. On a highway, you look for the way to your destination city. What kind of information do signs with a green background give you?
Show answer & explanation
Correct answer: D. Green guide signs point the way, listing destinations, how many miles remain, and which exits to take. They inform rather than command, so no action is required. Think of green as the color that says go this way.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. On any road sign, what does the color red always signal to drivers?
Show answer & explanation
Correct answer: D. Red is reserved for the strongest commands: stop, yield, do not enter, and wrong way. It marks actions that are forbidden or must halt. When red appears, something about your movement has to change right now.
23. 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.
24. 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.
25. 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.
