  1. 1. You are behind a snow plow working on a highway. What is the correct way to drive?

    Show answer

    Answer C: Stay well back and do not try to pass it

    A plow throws snow, runs wider than its body and works on the poor surface ahead of it, so the cleared road behind it is the safest place to be.

  2. 2. Besides motorist services and tourist information, a blue sign background is also used for

    Show answer

    Answer B: evacuation route signing

    Blue is assigned to road user services, tourist information and evacuation routes, so hurricane and other evacuation routes are signed in blue.

  3. 3. You are approaching an uncontrolled intersection on a residential street where parked cars hide the cross street. What is the correct approach?

    Show answer

    Answer B: Slow enough to stop and creep out until you can see

    Without a sign or signal you still have to be able to yield, and you cannot yield to traffic you have not seen.

  4. 4. Which of these is an early warning that you are too tired to keep driving?

    Show answer

    Answer C: Not remembering the last few miles you drove

    Memory gaps, repeated yawning, heavy eyelids and drifting are the body signaling that sleep is winning, and they mean stop rather than push on.

  5. 5. Another driver has pulled out to pass you. What should you do?

    Show answer

    Answer A: Stay in your lane, keep your speed steady or ease off, and let the pass finish

    Accelerating while being passed forces the other driver to stay in the opposing lane longer, so the safe response is to hold or slightly reduce speed and stay right.

  6. 6. A school sign combined with an AHEAD plaque, or with a plaque giving a distance in feet, forms an assembly that

    Show answer

    Answer B: warns of a school crossing located further along the road

    The school advance crossing assembly is placed before the crosswalk to give drivers notice, while a different assembly marks the crossing itself.

  7. 7. You must stop for a train at a highway-rail crossing. Where should you stop?

    Show answer

    Answer B: Behind the stop line, gate or signal and well clear of the nearest rail

    Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.

  8. 8. Where is the best place in the car for a child safety seat?

    Show answer

    Answer A: In the rear seat, secured either with the belt or with the lower anchors

    The rear seat is furthest from most impacts and from the front airbags, and the seat must be locked in with the belt or the anchors.

  9. 9. The curb ahead is signed as a bus stop. May you wait there with your vehicle?

    Show answer

    Answer C: No, the space must stay clear for buses

    A bus stop must stay open so that a bus can reach the curb and let passengers on and off safely, so no other vehicle may occupy it.

  10. 10. You are backing out of a driveway that crosses a public sidewalk. What should you do?

    Show answer

    Answer C: Stop before the sidewalk and check both ways

    Walkers, runners and riders use the sidewalk at speeds that can bring them into your path in a second, so the stop and the look belong before the sidewalk, not after it.

  11. 11. A yellow diamond showing a bicycle is posted on a rural road. What should a driver expect?

    Show answer

    Answer A: Bicyclists crossing or riding along the roadway there

    The bicycle warning sign is used where a bikeway crosses the road or where riders are likely to be in the traffic lanes, so drivers should look carefully and pass wide.

  12. 12. What is the rule about leaving a child or a pet in a parked vehicle?

    Show answer

    Answer A: Never do it; the inside can turn deadly hot very quickly

    The inside of a parked vehicle heats far faster than the air outside, and cracking a window does not prevent it, so a child or animal must never be left there.

  13. 13. A high-occupancy vehicle lane is separated from the general lanes by a pair of solid white lines with a gap every so often. Where may you enter or leave it?

    Show answer

    Answer D: Only at the openings where the solid lines are broken

    The solid lines forbid crossing, so entry and exit are limited to the designated openings where the marking is broken.

  14. 14. You are on a city street with two lanes in your direction, cars parked along the curb and driveways every few yards. Which lane is usually safer?

    Show answer

    Answer B: The lane farther from the curb, away from opening doors and vehicles pulling out

    Most of the hazards on such a street come from the curb side, so the inside lane gives you more space and more time to react.

  15. 15. A set of reversible express lanes is closed off with gates and signs while it runs the other way. What must you never do?

    Show answer

    Answer C: Enter past a closed gate or a sign showing the lanes are closed

    When reversible lanes are closed they may already be carrying traffic in the opposite direction, so entering past a gate can put you head-on into that traffic.

  16. 16. What is the best way to keep your phone from distracting you on a trip?

    Show answer

    Answer D: Silence it and stow it before you start

    A phone you cannot hear and cannot reach cannot tempt you, which is far more reliable than deciding case by case while you drive.

  17. 17. Your vehicle stalls on a railroad crossing and will not restart. What should you do first?

    Show answer

    Answer A: Get everyone out and away from the tracks immediately

    Everyone must leave the vehicle and move well clear of the tracks at once, walking toward the train at an angle so that debris from an impact travels away from you.

  18. 18. You are parking on a hill where there is no curb, whether facing up or down. Which way should the front wheels point?

    Show answer

    Answer B: Toward the shoulder, so the vehicle would roll away from the traffic lanes

    With no curb to stop the vehicle, the wheels are turned toward the edge of the road so that a runaway vehicle leaves the roadway instead of entering it.

  19. 19. The route marker used for an Interstate highway is a shield with

    Show answer

    Answer A: white numerals on a blue field under a red band carrying the word INTERSTATE

    The Interstate route marker is a cutout shield with a white border, the word INTERSTATE in white on red across the top and the route number in white on blue.

  20. 20. A pedestrian starts to cross against a Do Not Walk signal, right in front of you. What should you do?

    Show answer

    Answer D: Slow or stop and let the person reach safety

    Even when a pedestrian is crossing unlawfully, a driver must take reasonable care to avoid hitting that person.

  21. 21. You are entering a marked school zone during the posted hours. What should you do?

    Show answer

    Answer A: Slow to the school zone limit and watch for children

    The school zone limit applies throughout the posted hours, whether or not you can see any children at that moment.

  22. 22. You are stopped inside an intersection waiting for a gap to turn left. How should your front wheels be positioned?

    Show answer

    Answer C: Pointing straight ahead until you actually begin the turn

    If your wheels are already turned left and another vehicle strikes you from behind, you would be pushed into oncoming traffic.

  23. 23. Heavy rain has left standing water on the road where this sign is posted. What does the law expect of the driver?

    A white vertical rectangle with a black border and black legend
    Show answer

    Answer C: Driving below the posted figure, at a speed that suits the conditions

    Drivers must adapt to conditions, so in rain, fog, snow or dense traffic the safe speed falls below the posted maximum and keeping to that maximum can itself be an offense.

  24. 24. A pedestrian near the curb is staring at a phone and not looking at traffic. What should you do?

    Show answer

    Answer A: Slow down and be ready to stop, because the pedestrian may step out without looking

    Distracted pedestrians step into the street without checking. Assume they have not seen you and give yourself time and space to stop.

  25. 25. Your vehicle leaves the road and enters deep water. What gives you the best chance of escape?

    Show answer

    Answer B: Release your seat belt and get out through a window as quickly as possible

    Water pressure holds the doors shut, so a window is the reliable exit and the first seconds after entry are the best time to use it.
