25 questions. Pick an answer to see if it is right and why; you need 20 correct answers to pass.

  1. 1. You have turned onto a street and see parked cars facing you and headlights coming toward you. What has probably happened?

    Show answer

    Answer C: You have turned the wrong way onto a one-way street

    Vehicles parked facing you and headlights approaching in your lane are the classic signs of driving against the flow on a one-way street.

  2. 2. You are traveling at 55 mph on a rural road and come up behind a horse-drawn buggy. What is the main danger?

    Show answer

    Answer D: You close on it very quickly because it moves at walking pace

    A buggy travels only a few miles an hour, so the gap closes far faster than drivers expect and there is very little time to brake once you see it.

  3. 3. A large truck ahead of you in a roundabout is using part of both lanes as it goes around. What is the correct response?

    Show answer

    Answer B: Stay back and give it room until it leaves the roundabout

    Long vehicles need extra width to get around the central island, so drivers behind must hold back rather than share the space beside them.

  4. 4. A driver reaches this sign and the intersecting roadway is completely clear. What is required?

    A downward pointing white triangle with a wide red border
    Show answer

    Answer D: Slowing to a speed that allows stopping, then going on without stopping if the way stays clear

    This control asks the driver to slow down and be ready to stop, and a full stop becomes necessary only when traffic or pedestrians would otherwise be interfered with.

  5. 5. When is a driver or rider most likely to need hand and arm signals instead of the vehicle turn signal lamps?

    Show answer

    Answer D: When the lamps have failed or cannot be seen because of glare or a load

    Hand and arm signals replace or reinforce the lamps whenever the lamps do not work or cannot be seen clearly by other road users.

  6. 6. How is the yield sign shaped and colored?

    Show answer

    Answer C: A downward-pointing triangle with a wide red border and a red legend on white

    The yield sign is a downward-pointing equilateral triangle with a wide red border and the legend in red on a white background, an outline used for no other message.

  7. 7. A speed limit sign carries a second panel reading TRUCKS 55. What does that panel do?

    Show answer

    Answer B: It sets a lower legal limit for trucks

    A truck speed limit panel is regulatory, so trucks are bound by the lower figure while other traffic keeps to the main limit.

  8. 8. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?

    Show answer

    Answer A: Pull to the right edge and stop until it passes

    On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.

  9. 9. A tractor-trailer is backing slowly across the roadway to enter a loading dock. What should you do?

    Show answer

    Answer C: Stop and wait until the truck has finished the maneuver

    A backing truck driver has a very limited view and the trailer can swing unexpectedly. Trying to squeeze past in either direction risks being crushed.

  10. 10. You are waiting in a left-turn lane at a green light when a fire engine with lights and siren comes toward you in the oncoming lanes. What should you do?

    Show answer

    Answer D: Hold your position and let the fire engine pass

    Turning across the path of an approaching emergency vehicle is exactly what you must not do; stay put until it has gone by.

  11. 11. How far forward should a rider sit on the seat?

    Show answer

    Answer D: Far enough forward that the arms are slightly bent on the grips

    Slightly bent arms let the rider steer with the handlebars instead of using the arms to prop up the upper body.

  12. 12. In most states, how far before a turn must your signal already be on in city traffic?

    Show answer

    Answer B: At least 100 feet, roughly the length of six or seven cars

    Most states require the signal for at least 100 feet before a turn in city driving, which gives drivers behind you time to react before you slow; several require more at higher speeds.

  13. 13. How much clear road do driver manuals say you need before starting a pass at highway speed on a two-lane road?

    Show answer

    Answer C: Enough to complete the pass and return, roughly ten to twelve seconds of travel

    At highway speed the whole maneuver of pulling out, overtaking and returning takes roughly ten to twelve seconds, and every foot of that has to be visible before you start.

  14. 14. A driver hunting for an on-ramp meets this sign at the mouth of the pavement ahead. What is the correct action?

    A red square with a wide white horizontal bar across the middle
    Show answer

    Answer C: Keep out of that roadway and look for the proper approach elsewhere

    The restriction is absolute and does not depend on how much traffic is present, so the driver has to reach the highway by an approach built for entering vehicles.

  15. 15. Where must the engine cut-off switch be set before the starter button will crank the engine?

    Show answer

    Answer A: In the run position

    The cut-off switch sits in the ignition circuit, so the engine will not start or run while it is set to off.

  16. 16. What does a sign reading Slower Traffic Keep Right require?

    Show answer

    Answer C: Traffic moving slower than the general flow must use the right-hand lane

    The sign applies to any vehicle traveling below the speed of the traffic around it, which must keep right so faster vehicles can use the lanes to the left.

  17. 17. A driver slows to walking pace at this sign, never stops rolling and eases into the intersection. How is that treated?

    A red eight sided sign with a white border and white lettering
    Show answer

    Answer B: It is a violation, because the vehicle never came to a complete halt

    What is required is a full halt with the wheels no longer turning, so slowing down, however carefully, does not satisfy it.

  18. 18. Which of these makes you unpredictable to other drivers?

    Show answer

    Answer B: Changing lanes suddenly without signaling, to save a moment

    An unsignalled, sudden lane change gives nobody time to react and is a common cause of sideswipe collisions.

  19. 19. A downpour has just started on a street with a visible dark strip down the middle of the lane. Where should you ride?

    Show answer

    Answer A: In the left or right portion of the lane, away from the greasy center strip

    Dripped oil and grease build up in the center of the lane, and water floats that film to the top, so the tire tracks on either side offer better grip.

  20. 20. Why do streetcar or light rail rails set into a street deserve extra care from a rider?

    Show answer

    Answer B: The groove alongside the rail can catch a front tire crossed at a shallow angle

    The groove beside an embedded rail is just wide enough to trap a motorcycle tire, so cross rails at as steep an angle as your lane allows.

  21. 21. What is the first thing to do once your disabled vehicle is stopped on the shoulder?

    Show answer

    Answer A: Switch on the hazard warning lights so other drivers can see the vehicle

    Hazard lights are the fastest way to make a stopped vehicle visible, and everything else can follow once traffic has been warned.

  22. 22. Why is passing another vehicle a bad idea in dense fog?

    Show answer

    Answer C: You cannot see far enough ahead to know the passing lane is clear

    A pass needs a clear view of the road well beyond the vehicle you are overtaking, and fog takes exactly that away.

  23. 23. What happens when alcohol is combined with another drug that also affects the nervous system?

    Show answer

    Answer B: Impairment is often far greater than either one alone would produce

    Combined substances can multiply each other's effects, producing impairment well beyond what a driver would expect from either one taken separately.

  24. 24. A signal stands part way up a freeway entrance ramp and turns green briefly again and again. How many vehicles does such a signal normally release on each green?

    Show answer

    Answer A: One for each lane of the ramp

    A ramp control signal releases a single vehicle per lane on each green so that vehicles reach the merge one at a time instead of in a bunch.

  25. 25. What does a pre-ride check of a hydraulic brake system cover?

    Show answer

    Answer C: The fluid level and any sign of a leak at the hoses and fittings

    A falling fluid level means either worn pads or a leak, and a leaking hose or fitting can empty the system without warning.
