Alaska Road Signs Practice Test

Sharpen the skill the General Knowledge Test leans on most: 25 questions on road sign shapes, colors, and meanings, each explained in plain English. The real DMV General Knowledge Test has 20 questions, and you need 16 correct (80%) to pass.

  1. 1. 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.

  2. 2. 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.

  3. 3. 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.

  4. 4. 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.

  5. 5. 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.

  6. 6. 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.

  7. 7. 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.

  8. 8. 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.

  9. 9. 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.

  10. 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. 11. 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.

  12. 12. 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.

  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. 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.

  15. 15. 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.

  16. 16. 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.

  17. 17. 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.

  18. 18. 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.

  19. 19. 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.

  20. 20. 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.

  21. 21. 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.

  22. 22. 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.

  23. 23. 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.

  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 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.
