Kansas 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 DOV Knowledge Test has 25 questions, and you need 20 correct (80%) to pass.
Question 1 of 25
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. An orange sign with a black arrow reads DETOUR. What is this sign telling you?
Show answer & explanation
Correct answer: A. Detour signs guide you along a temporary route when the normal road is closed, often for construction or an emergency. Keep following the arrows until the detour ends, and the route will return you to your original road.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
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. 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.
20. 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.
21. 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.
22. 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.
23. 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.
24. 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.
25. 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.
