  1. 1. Besides impact protection, how does a light colored helmet help the rider?

    Show answer

    Answer A: It sits above surrounding traffic, so drivers pick it out sooner

    A light or high visibility helmet sits above the traffic around the rider and is often the first part of a motorcycle a driver notices.

  2. 2. Federal law lets a state open its high-occupancy vehicle lanes to certain vehicles carrying only one person. Which of these is covered by that allowance?

    Show answer

    Answer B: Motorcycles

    Federal law lets states allow motorcycles into high-occupancy vehicle lanes regardless of the number of occupants, because keeping riders in the flow is safer than the alternative.

  3. 3. Besides school signing, which warning signs may also use a fluorescent yellow-green background?

    Show answer

    Answer C: Pedestrian and bicycle warning signs

    Pedestrian crossing, bicycle and playground warning signs may use either the standard yellow or the fluorescent yellow-green background, which draws extra attention where people outside vehicles are present.

  4. 4. You are stopped at a stop sign waiting to turn onto a highway where traffic moves at 55 mph. How should you choose your gap?

    Show answer

    Answer A: Wait for a much larger gap than the one you would accept on a city street

    Fast traffic covers ground while you are still accelerating, so the gap that feels adequate at 25 mph is dangerously short at highway speed.

  5. 5. A wide solid white line separates the through lanes from an exit lane. What does it tell drivers?

    Show answer

    Answer B: The choice of lane should already have been made

    A channelizing line marks where the paths separate and crossing it is discouraged or prohibited, so the lane change has to happen upstream.

  6. 6. When should a helmet be replaced?

    Show answer

    Answer B: After a crash, or if the shell is cracked or the straps are frayed

    The energy absorbing liner is designed to crush once, so a helmet that has taken an impact or shows damage no longer offers full protection.

  7. 7. At a freeway exit ramp, this sign normally backs up which other regulatory sign posted nearer to the ramp terminal?

    A red rectangle with white lettering
    Show answer

    Answer D: The sign that forbids entering that roadway at all

    The two work as a pair at ramp terminals: one keeps drivers from turning in, and this one sits farther along to catch a driver who has already entered.

  8. 8. A separate right-turn lane leads onto the cross street and carries a yield sign. What does it require?

    Show answer

    Answer D: Slowing and giving way to traffic and people, stopping if needed

    A yield requires you to slow, give way to traffic in the lane you are joining and to pedestrians, and stop only if that is what safety demands.

  9. 9. Traffic is entering the freeway from a ramp ahead of you and you are in the right lane. What should you do?

    Show answer

    Answer C: Move to another lane if it is safe, or adjust your speed to make room

    Merging drivers may have little room to adjust. Helping them in by changing lanes or easing your speed prevents conflicts even though they must legally yield to you.

  10. 10. You arrive at a four-way stop after two other vehicles have already stopped there. When is it your turn?

    Show answer

    Answer A: After both of the earlier vehicles have gone

    Vehicles clear a four-way stop in the order they arrived, so the third driver to stop is the third to go.

  11. 11. May you park in front of a public or private driveway?

    Show answer

    Answer A: No, blocking a driveway is prohibited even for a short time

    Parking in front of a driveway blocks the property owner from entering or leaving, and the prohibition does not depend on how long you stay.

  12. 12. Where is a U-turn most clearly unsafe and generally prohibited?

    Show answer

    Answer D: On a curve or near a hill crest, where other drivers cannot see you

    U-turns are barred where approaching drivers cannot see you in time, such as on a curve or near the top of a hill.

  13. 13. You are approaching a highway-rail grade crossing marked only with a crossbuck sign. What does that sign require?

    Show answer

    Answer A: Yield to any approaching train and cross only when the tracks are clear

    The crossbuck is a regulatory yield sign, and a train can never stop or steer around a vehicle, so the driver must always give way.

  14. 14. In Iowa, what is the speed limit for all vehicular traffic where no other speed restriction applies or is posted?

    Show answer

    Answer C: 55 miles per hour

    Iowa Code section 321.285 sets fifty-five miles per hour as the speed limit for all vehicular traffic unless another restriction in that section applies.

  15. 15. You are very angry after an argument and about to drive. What should you know?

    Show answer

    Answer A: Strong emotions can impair judgment and attention much like alcohol

    Anger, grief and stress pull attention inward and encourage risk taking. Give yourself time to settle down before getting behind the wheel.

  16. 16. You are first in the queue at a red light with a marked crosswalk. Where should your vehicle stop?

    Show answer

    Answer A: Behind the stop line, so that the crosswalk stays clear

    Stopping short of the line keeps the crosswalk usable for people on foot and keeps your vehicle out of the path of turning traffic.

  17. 17. What happens to an Iowa motorized bicycle license when the holder is convicted of a moving traffic violation?

    Show answer

    Answer C: It is canceled, and the holder may reapply thirty days later

    Iowa Code section 321.189 cancels a license valid only for a motorized bicycle upon a conviction for a moving traffic violation, and allows reapplication thirty days after the date of cancellation.

  18. 18. An emergency vehicle with flashing lights and a siren is approaching from behind on a two-way street. What should you do?

    Show answer

    Answer C: Pull over to the right edge of the road and stop until it passes

    Clearing a path by pulling to the right and stopping gives the emergency vehicle a predictable route, while stopping in mid-lane or inside an intersection blocks that path.

  19. 19. Your navigation device tells you to turn where a road sign says the turn is closed. What should you do?

    Show answer

    Answer B: Follow the signs and what you can see

    A device works from stored data that can be out of date, while signs and the road in front of you show the situation now, so the road wins every time.

  20. 20. In a staggered group, where does the leader normally ride?

    Show answer

    Answer B: In the left portion of the lane

    The leader takes the left portion of the lane, which gives a wide view of the road ahead and sets up the staggered pattern for everyone behind.

  21. 21. Your light turns green and a driver on the cross street enters against a red. What should you do?

    Show answer

    Answer D: Hold back and let that vehicle go through

    Giving up a right of way you are entitled to is the only way to avoid a crash with a driver who has already failed to yield.

  22. 22. You realize at the last moment that you have passed the street where you meant to turn. What should you do?

    Show answer

    Answer D: Keep going and turn around where it is safe and legal

    A missed turn is a minor inconvenience; braking suddenly, backing up or turning across traffic to recover it causes crashes.

  23. 23. Why would a restriction like this one be applied to a stretch of road?

    A yellow sign shaped like a horizontal triangle pointing right, with black lettering
    Show answer

    Answer A: Because there is not enough visible road ahead to complete a pass safely

    Limits on overtaking are set where a hill, a curve or an obstruction leaves too little sight distance for a driver to pull out, pass and return before meeting oncoming traffic.

  24. 24. A steady downward green arrow is displayed over a lane. What does it indicate?

    Show answer

    Answer C: The lane is open to traffic in your direction

    A steady downward green arrow means the lane it points to is open to traffic traveling in your direction.

  25. 25. The lights at a highway-rail grade crossing begin to flash red as you approach. What must you do?

    Show answer

    Answer B: Stop short of the tracks and wait until the lights stop and no train is near

    Flashing red lights at a crossing require a stop clear of the tracks, and you may proceed only once the lights have stopped, any gates are fully raised and no train is approaching.
