  1. 1. A vehicle ahead of you displays a reflective orange triangle on its rear. What does that emblem tell you?

    Show answer

    Answer B: The vehicle is built to travel at 25 mph or less

    The orange triangle is the slow moving vehicle emblem used on farm and construction equipment designed for 25 mph or less, warning you that you are closing on it much faster than it appears.

  2. 2. The added lane warning sign tells a driver that

    Show answer

    Answer A: an extra lane begins ahead, so entering traffic does not have to merge into an existing lane

    Where a lane is added, traffic entering the roadway gets a lane of its own, so merging is not required, although drivers should still watch the vehicles beside them.

  3. 3. Why do experienced riders squeeze the clutch lever while starting the engine, even with the neutral light showing?

    Show answer

    Answer A: In case a gear is engaged, so the motorcycle cannot lurch forward

    A neutral light can be wrong, and a disengaged clutch means the machine stays still even if the transmission is actually in gear.

  4. 4. The throttle sticks open and will not close when you roll it back. What should you do?

    Show answer

    Answer B: Squeeze in the clutch and shut the engine down with the cut-off switch

    Pulling in the clutch cuts power to the rear wheel immediately, and the cut-off switch stops the engine without the rider letting go of the handlebars.

  5. 5. You have just ridden over a large object lying in the road. What should you do next?

    Show answer

    Answer A: Pull over when it is safe and check the tires and rims for damage

    An impact can cut a tire, dent a rim or bend a fork without giving any immediate change in how the machine feels, so it deserves a look.

  6. 6. What should a group agree on before the ride begins?

    Show answer

    Answer A: The route, the fuel and rest stops, and the hand signals to be used

    Settling the route, the stops and the signals before departure keeps the group together and avoids sudden, confusing decisions once it is moving.

  7. 7. What is the only reliable remedy for a driver who is sleepy?

    Show answer

    Answer A: Sleep

    Caffeine, fresh air and noise may make you feel alert for a few minutes, but they do not remove the need for sleep. Stop somewhere safe and rest.

  8. 8. How long is the Iowa revocation for a driver under twenty-one whose test shows .02 or more but less than .08, with no previous revocation?

    Show answer

    Answer A: Sixty days

    Iowa Code section 321J.12 sets a sixty-day revocation for a driver under twenty-one testing at .02 or more but less than .08 with no previous revocation, and ninety days if a previous revocation exists.

  9. 9. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?

    Show answer

    Answer B: In the first traffic lane to the left of the bike lane

    A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.

  10. 10. On an overhead guide sign, the small exit number panel sits above the left-hand end rather than the right. What does that placement tell you?

    Show answer

    Answer A: The exit leaves from the left side of the roadway

    The exit number plaque is placed on the side from which the ramp leaves, which gives advance notice of the unusual left-hand exit.

  11. 11. Which family of signs normally uses a rectangle that is wider than it is tall?

    Show answer

    Answer B: Guide signs, which name routes and destinations

    Guide signs are laid out as horizontal rectangles because they have to carry route numbers, place names and distances side by side.

  12. 12. You are clear of the tracks after your vehicle stalled on a crossing. Whom should you contact?

    Show answer

    Answer C: The emergency number posted on the blue sign at the crossing, or 911

    Grade crossings carry an emergency notification sign with a railroad phone number and a crossing identification number so that approaching trains can be stopped, and 911 works if that sign is not visible.

  13. 13. A sign warns that the right lane ends ahead, and traffic is still flowing freely. What should you do if you are in that lane?

    Show answer

    Answer C: Signal, adjust your speed and move left in good time before the lane ends

    When traffic is moving freely there is room to merge early and smoothly, which avoids the last-second lane change at the closure point.

  14. 14. On a rural two-lane road you pass small blue signs, each naming one business with an arrow and a distance. What are they?

    Show answer

    Answer D: Tourist-oriented directional signs for traveler businesses

    Tourist-oriented directional signs carry a white legend on blue and are used on rural conventional roads to guide travelers to eligible businesses.

  15. 15. How does the distance needed to stop change when a rider doubles speed?

    Show answer

    Answer D: It grows to roughly four times the original distance

    Braking distance rises with the square of speed, so twice the speed needs roughly four times the distance in which to stop.

  16. 16. An orange background with a black legend on a sign indicates

    Show answer

    Answer B: a temporary traffic control or work zone situation

    Orange is reserved for temporary traffic control signing, so an orange sign means conditions have been altered for work or another temporary operation.

  17. 17. A yellow diamond showing arrows arranged in a circle warns of

    Show answer

    Answer B: a circular intersection such as a roundabout ahead

    The circular intersection warning sign announces a roundabout or traffic circle so drivers can slow down and prepare to yield to traffic already circulating.

  18. 18. How should a driver respond to this sign?

    A yellow diamond with black lettering
    Show answer

    Answer C: Slow down before reaching the rough spot and cross it at a steady, low speed

    Losing speed before a sharp rise in the pavement keeps the vehicle settled, while braking or accelerating on top of it unsettles the suspension and costs grip.

  19. 19. Why should a rider downshift one gear at a time instead of skipping several at once?

    Show answer

    Answer D: Skipping gears can lock the rear wheel through sudden engine braking

    Dropping several gears at once forces engine speed far above what road speed supports, and the rear tire can be dragged into a skid when the clutch comes out.

  20. 20. You and an opposing driver reach a four-way stop at the same time and both of you are turning right. What should happen?

    Show answer

    Answer C: Both may turn at the same time into their own lanes

    Two opposing right turns take drivers into different lanes without crossing, so both can proceed together once pedestrians are clear.

  21. 21. On a rural road, the driver of a slow farm tractor ahead of you signals a left turn even though there is no road or driveway in sight. What should you do?

    Show answer

    Answer B: Stay behind the tractor, because it may be turning into a field entrance

    Farm equipment often turns into fields through gaps you cannot see, and it may swing wide to do so. Passing a vehicle that is signaling a left turn is a common cause of crashes.

  22. 22. Which of these is announced with the same family of signs as the facility shown here?

    A blue square with a white letter H
    Show answer

    Answer A: A rest area for travelers

    A rest area belongs to the same motorist service series, which points travelers toward facilities such as fuel, food, lodging and medical care.

  23. 23. You need to reverse direction on a busy street. Which choice is usually safest?

    Show answer

    Answer D: Driving around the block and using the intersections instead

    Going around the block uses normal turns at controlled intersections instead of stopping across live traffic lanes.

  24. 24. A large electronic advertising sign beside the road catches your eye. What should you do?

    Show answer

    Answer A: Glance briefly and return your eyes to the road

    Bright changing displays are designed to hold attention, so treat them like any roadside object and give them no more than a brief glance.

  25. 25. You turn from asphalt onto a loose gravel road. What should you do about your speed?

    Show answer

    Answer D: Lower it, since grip is reduced and stopping takes longer

    Loose gravel gives far less grip than pavement, so speed must come down for both steering and stopping.
