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

  1. 1. This sign leads to a crossing that has no gates and no flashing lights. What does that mean for the driver?

    A yellow circle showing a black cross and the letters R R in the side quarters
    Show answer

    Answer D: Nothing will warn of an approaching train, so the driver must check the tracks personally

    At a passive crossing there is no active device to announce a train, so the whole judgment rests on the driver, who must approach slowly enough to stop after looking along the track.

  2. 2. The gates at a railroad crossing are down, and you can see that the road beyond them is clear. What is the correct action?

    Show answer

    Answer A: Wait until the gates rise completely and the lights go out

    Lowered gates mean rail traffic is expected, and driving around them removes the only protection the crossing provides.

  3. 3. A rider uses only the rear brake for a quick stop. What is the result?

    Show answer

    Answer B: A much longer stop, and a rear wheel that locks easily

    With weight thrown forward the rear tire has little grip left, so it gives up only a small share of the available braking and skids under heavy pressure.

  4. 4. A driver behind you on a two-lane road clearly wants to pass. Why should you not wave that driver past?

    Show answer

    Answer B: You cannot see the whole road ahead for them and they may rely on your signal

    Waving another driver out invites them to trust your judgment of a road you cannot see well enough, and the decision to pass belongs to the driver making it.

  5. 5. How often should a rider change position within the lane?

    Show answer

    Answer C: As often as the traffic, the road surface and the hazards around you change

    Lane position is a tool for keeping space and visibility, and both of those change constantly as traffic and road conditions change.

  6. 6. A broken white line separates your lane from the lane beside it. What does it indicate?

    Show answer

    Answer C: Both lanes carry traffic in the same direction and lane changes are permitted

    White lines separate lanes of traffic moving in the same direction, and a broken white line means changing lanes across it is permitted when it is safe.

  7. 7. On a long uphill grade a second lane opens on the right and a sign directs slower traffic into it. You are towing a trailer and holding up a line of vehicles. What should you do?

    Show answer

    Answer A: Move into the right-hand lane and let the faster traffic use the left lane

    A climbing lane exists so that slow vehicles can be passed safely, and the slower vehicle is the one that belongs in it.

  8. 8. Why must a rider turn the head and look before changing lanes?

    Show answer

    Answer A: Mirrors leave blind spots that only a direct look can cover

    Motorcycles have blind spots just as cars do, and a vehicle hidden in one will not appear in the mirrors at all.

  9. 9. Which motorcycles must display at least one lighted headlamp whenever they are operated on Iowa highways?

    Show answer

    Answer B: Motorcycles of model year 1977 or later

    Iowa Code section 321.275 requires a lighted headlamp on any 1977 or later model year motorcycle and on any model year motorized bicycle operated on the highways.

  10. 10. This sign is still standing late at night, and nobody is working. What should the driver assume?

    An orange diamond with black lettering
    Show answer

    Answer B: The layout may still be altered, so the same care and reduced speed apply

    Narrowed lanes, shifted alignments, dropped pavement edges and parked equipment remain overnight, so the hazard does not end when the crew goes home.

  11. 11. An orange sign reads RIGHT LANE CLOSED AHEAD. What is the correct response?

    Show answer

    Answer A: Move left in good time and keep a steady pace

    The sign is placed well before the taper so that drivers can merge smoothly rather than braking hard where the lane actually closes.

  12. 12. On a two-lane road, a solid yellow line runs on your side of the center while a broken yellow line runs on the other side. What does this mean?

    Show answer

    Answer D: You may not pass, although oncoming drivers may

    Passing restrictions are read from the line closest to your own lane, so a solid yellow line on your side creates a no-passing zone for you alone.

  13. 13. Two solid yellow lines are painted down the center of a two-way road. What do they mean?

    Show answer

    Answer B: Traffic in neither direction may cross them to pass

    A double solid yellow line marks a no-passing zone that applies to traffic traveling in either direction.

  14. 14. A lane along the right edge is set off by a solid white line and marked with a bicycle symbol. How should a driver treat it?

    Show answer

    Answer B: Stay out of it except for the short distance needed to turn or cross where that is allowed

    A marked bicycle lane is set aside for bicycle traffic, and motor vehicles may enter it only briefly where turning or crossing is permitted.

  15. 15. How does Iowa treat a conviction for using an electronic device while driving, for licensing purposes?

    Show answer

    Answer B: As a moving violation

    Iowa Code section 321.276 states that a violation of the electronic device section shall be considered a moving violation for purposes of chapter 321 and the rules adopted under it.

  16. 16. What does a broken line indicate, whatever color it is painted?

    Show answer

    Answer C: That crossing it is permitted

    A broken line always describes a permissive condition, and the color then tells the driver whether the traffic beyond it runs the same way or the opposite way.

  17. 17. You are driving down a parking aisle and reach the main lane that runs along the front of the store. What is the usual rule?

    Show answer

    Answer C: The main through lane has the right of way over the vehicles leaving the aisles

    In a parking lot the wide lane that runs across the ends of the aisles works like a through road, and drivers leaving an aisle yield to it.

  18. 18. Why should you avoid parking over tall dry grass or a pile of dead leaves?

    Show answer

    Answer B: Because the hot exhaust can set the dry material on fire

    The exhaust system stays hot for a long time after a drive and can ignite dry vegetation underneath the vehicle.

  19. 19. You are turning left from a two-way street onto another two-way street. Where should you begin and end the turn?

    Show answer

    Answer B: Begin in the lane just right of the center line and finish just right of the center line of the new street

    You approach a left turn from the lane closest to the center line and enter the new roadway just to the right of its center line, which keeps you clear of oncoming traffic.

  20. 20. When downshifting as the motorcycle slows, what keeps the rear tire from skidding?

    Show answer

    Answer A: Easing the clutch lever out smoothly instead of releasing it abruptly

    Letting the clutch out gradually lets engine speed and road speed match, so the rear wheel is not forced to slow suddenly.

  21. 21. How does riding in a formation change your responsibility for your own space cushion?

    Show answer

    Answer C: It does not change it, because each rider still manages their own space and decisions

    A formation organizes the group, but every rider remains responsible for their own following distance, escape paths and riding decisions.

  22. 22. You are the first driver on a road just after a storm. What should you plan for?

    Show answer

    Answer B: Branches, mud and other debris hidden around the next bend

    Storm debris lands where nobody has cleared it yet, often just beyond a curve or a crest, so reduce speed and look much further ahead.

  23. 23. You are riding at 30 miles an hour and need to move quickly to the left. What do your hands do?

    Show answer

    Answer D: Press forward on the left handgrip

    Above a walking pace a motorcycle turns by leaning, and pressing forward on the grip on the side you want to go is what starts the lean.

  24. 24. What is the basic rule for entering a roundabout?

    Show answer

    Answer B: Traffic already circulating goes first, and you wait for a gap

    Entering traffic yields to vehicles already going around the circle, which is what keeps a roundabout moving instead of locking up.

  25. 25. You are behind a slow vehicle on a two-lane road and a marked passing lane begins a mile ahead. What is the sensible choice?

    Show answer

    Answer D: Wait for the passing lane rather than using the opposing lane

    A passing lane lets you overtake without ever entering the lane used by oncoming traffic, which is far safer than a pass a minute earlier.
