Delaware Road Signs Practice Test
Sharpen the skill the Class D Knowledge Test (given with a highway sign and signal test and a rules of the road 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 DMV Class D Knowledge Test (given with a highway sign and signal test and a rules of the road test).
Question 1 of 25
1. 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, never a target.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. In a work zone, an orange sign warns of a flagger ahead. The flagger signals you to stop, even though the traffic light beyond is green. What should you do?
Show answer & explanation
Correct answer: C. Flaggers control traffic through work zones, and you must obey their directions even when they conflict with posted signs or signals. They can see hazards you cannot. Remember: in a work zone, the person outranks the light.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. 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.
23. 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.
24. 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.
25. 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.
