  1. 1. Which sign shape is reserved for one message only, the requirement to stop?

    Show answer

    Answer A: The octagon

    The octagon is used for the stop sign and for no other message, so the outline alone identifies the requirement even when the legend is hard to read.

  2. 2. Traffic safety experts describe three kinds of driver distraction. Which set is correct?

    Show answer

    Answer A: Visual, manual and cognitive

    Distraction takes the eyes off the road, the hands off the controls or the mind off driving, and many activities do more than one of those at once.

  3. 3. 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.

  4. 4. A sign reads REDUCED SPEED LIMIT AHEAD. What does it tell you?

    Show answer

    Answer D: A lower limit begins further along the road

    The sign gives advance notice so a driver can slow gradually, and the new figure takes effect at the speed limit sign that follows.

  5. 5. A hands free phone conversation is which kind of distraction?

    Show answer

    Answer C: Cognitive, because your mind leaves the road

    Hands free equipment removes the manual and visual parts of a call but not the mental load, and it is the mental load that makes a driver miss hazards.

  6. 6. Is it acceptable to drive with your vehicle straddling the line between two lanes?

    Show answer

    Answer D: No, you must drive as nearly as practical entirely within a single lane

    A vehicle astride the line takes up two lanes and leaves the drivers around it unable to predict where it will go.

  7. 7. 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.

  8. 8. You are in a passing zone that continues over the crest of a hill ahead. May you start a pass?

    Show answer

    Answer B: Only if you can finish it well before the crest

    Beyond the crest you cannot see oncoming traffic, so any part of the pass that happens there is being made blind.

  9. 9. 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.

  10. 10. What should you do with the key and your belongings when you leave the vehicle in a public lot?

    Show answer

    Answer D: Take the key with you, lock up and put valuables out of sight

    Most vehicle thefts are opportunistic: a key left behind or a bag in plain view is the invitation.

  11. 11. A driver ignores this sign and passes on the opposite side. What is the main risk?

    Show answer

    Answer B: Ending up on the wrong side of a divider, facing traffic coming the other way

    The sign settles which side of a fixed divider is the legal one, so taking the other side sends the vehicle into the opposing stream or straight at the obstruction.

  12. 12. Four vehicles reach a four-way stop from all four directions at the same instant. How is the deadlock resolved?

    Show answer

    Answer C: Each driver yields to the vehicle on the right and they go one by one

    Yielding to the right applies to every driver, so the group untangles itself as drivers take turns rather than moving together.

  13. 13. How do strong emotions affect driving?

    Show answer

    Answer B: They narrow your attention and make risky decisions more likely

    Anger, worry and excitement all take attention away from the driving task and push drivers toward decisions they would not normally make.

  14. 14. How does being tired change your total stopping distance?

    Show answer

    Answer A: It lengthens it, because you take longer to notice and react

    Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.

  15. 15. A flashing red lamp is mounted above a stop sign at a rural intersection. What does it add?

    Show answer

    Answer C: Emphasis, while the required stop stays the same

    A stop beacon makes an easily missed stop sign more visible, but it neither adds to nor takes away from the obligation the sign already imposes.

  16. 16. You brake hard on a wet road and need to steer around a stalled car. How do antilock brakes help you do that?

    Show answer

    Answer B: They stop the wheels locking, so the tires can still turn the vehicle

    Locked wheels slide and cannot change direction. By preventing lockup the system lets you brake at full force and steer at the same time.

  17. 17. How does a driver become an habitual offender in Iowa under the graver of the two definitions?

    Show answer

    Answer B: Three or more of the listed serious offenses within a six-year period

    Iowa Code section 321.555 defines an habitual offender as a person who accumulates three or more of the listed serious offenses, singly or in combination, within a six-year period.

  18. 18. You are driving forward into a perpendicular space with a large pickup parked on the right of it. How should you take it?

    Show answer

    Answer D: Stay wide, turn in late and keep clear of the pickup

    Starting the turn later keeps the rear of your car away from the vehicle beside the space, which is exactly what a tight early turn clips.

  19. 19. You want to reverse direction but the street is too narrow for a U-turn. What is the alternative?

    Show answer

    Answer D: Make a three-point turn, or go around the block in heavy traffic

    Where there is not enough width for a U-turn, the three-point turn does the job in stages, and on a busy street going around the block is safer still.

  20. 20. Blue pavement markings are used together with white markings at

    Show answer

    Answer D: parking spaces reserved for people with disabilities

    Blue supplements the white markings of accessible parking spaces, which is the only assignment blue has on the pavement.

  21. 21. How long is a person declared an Iowa habitual offender on the basis of six reportable offenses in two years barred from holding a license?

    Show answer

    Answer B: One year

    Iowa Code section 321.560 sets a bar of one year for a person declared an habitual offender under the six-offense definition in section 321.555.

  22. 22. What does the traffic law actually say about the right of way?

    Show answer

    Answer B: It says who must yield; no driver is ever entitled to take the right of way

    The law describes who must yield. Right of way is something you give; insisting on it when another driver does not yield causes crashes.

  23. 23. The overhead signal above your lane changes to a steady yellow X. What should you do?

    Show answer

    Answer B: Prepare to move out of that lane

    A steady yellow X warns that the lane is about to close, so drivers should get ready to vacate it in favor of an open lane.

  24. 24. You and a driver coming from the opposite direction reach a four-way stop at the same time and you are both going straight ahead. What happens next?

    Show answer

    Answer D: Both of you may move off together, because your paths do not cross each other

    Opposing vehicles that are both going straight do not cross paths, so they can move off together once the intersection is clear.

  25. 25. Why should you stay out of an intersection you cannot clear, even on a green light?

    Show answer

    Answer B: Because you would block cross traffic when their signal turns green

    A vehicle stranded in the intersection blocks the cross street when its light turns green, which stalls the whole junction and traps emergency vehicles.
