1. You are about to pass a bicyclist on a narrow two-lane road. What is the correct way to do it?
Show answer
Answer A: Wait for a clear gap and move well left, giving the rider wide space
Pass a cyclist as you would a car: wait for clear road, change lane position to leave generous clearance, and return only when the rider is well behind you.
-
2. What is the best way to keep your phone from distracting you on a trip?
Show answer
Answer D: Silence it and stow it before you start
A phone you cannot hear and cannot reach cannot tempt you, which is far more reliable than deciding case by case while you drive.
-
3. How should a group merge onto a busy highway from an entrance ramp?
Show answer
Answer D: One rider at a time into gaps in traffic, re-forming once all are on
Each rider needs a gap and enough speed of their own, so the group merges individually and only takes up the staggered formation again afterward.
-
4. How should you follow a school bus in traffic?
Show answer
Answer A: Far enough back to see its lights and stop in time
A school bus stops often and with little warning, so a longer following distance gives you time to see the lights come on and stop clear of it.
-
5. Which effect appears as a drinker's blood alcohol level climbs well past the first drinks?
Show answer
Answer D: Loss of muscle control and steady steering
Higher levels of alcohol reach the parts of the brain that control movement, which shows up as clumsy steering, late braking and poor lane control.
-
6. How should a riding jacket fit?
Show answer
Answer B: Snug at the neck, wrists and waist so that it cannot balloon open
A jacket closed at the openings stays in place in a fall and does not flap in the wind, which is both tiring and distracting.
-
7. Your group reaches a work zone where the lane has been narrowed by cones and the surface is uneven. What should the formation do?
Show answer
Answer B: Move to single file and give each rider the whole width of the lane
A narrowed or broken surface leaves no spare room inside the lane, so riders need the full lane width each and must drop into single file.
-
8. You are driving through patchy fog on a highway. What should you be ready for?
Show answer
Answer B: Sudden dense banks where visibility drops within a few car lengths
Patchy fog can go from clear to nearly blind in a moment, so keep your speed low enough that a sudden bank does not leave you without room.
-
9. You are joining a highway from a short ramp that has no acceleration lane. What should you do?
Show answer
Answer A: Stop or slow at the end of the ramp and wait for a safe gap
Without an acceleration lane there is no room to match speed, so you must yield at the end of the ramp and enter only when a gap allows it.
-
10. You are approaching a horse and rider on a country road. What about your horn?
Show answer
Answer C: Do not sound it at all, because the noise can frighten the animal
A startled horse is dangerous to its rider and to you, so pass wide and slow and leave the horn alone.
-
11. Where among these is parking specifically prohibited?
Show answer
Answer A: On a bridge, in a tunnel or on railroad tracks
Bridges and tunnels have no safe refuge and cannot be widened, and a vehicle left on railroad tracks cannot be avoided by an approaching train.
-
12. What is the main advantage of a face shield over goggles?
Show answer
Answer D: It protects the whole face, not only the eyes
Goggles keep wind and debris out of the eyes, but a shatter resistant face shield also protects the rest of the face in a crash.
-
13. Which feature suggests that a helmet is an uncertified novelty helmet?
Show answer
Answer D: A shell less than one inch thick with no firm foam liner
Novelty helmets are typically thin and very light because they lack the stiff energy absorbing liner that a certified helmet uses to manage an impact.
-
14. Is dictating a message by voice a safe alternative to typing one?
Show answer
Answer C: No, it still takes attention from driving
Composing and checking a spoken message loads the mind and usually pulls the eyes to the screen anyway, so research finds it no safer than other phone use.
-
15. You are on an entrance ramp joining a busy freeway. What should you do with your speed in the acceleration lane?
Show answer
Answer D: Build it up to about the speed of the traffic you are joining
Merging works when your speed matches the traffic stream, because a large speed difference forces the drivers already on the freeway to brake or swerve.
-
16. A curb sign reads 2 Hour Parking, 8 AM to 6 PM, Monday to Saturday. When may you stay longer than two hours?
Show answer
Answer A: Outside those hours and on Sundays
A time limit applies only during the days and hours printed on the sign; outside them the ordinary parking rules apply.
-
17. The rider who was behind you has vanished from your mirrors. What should you do?
Show answer
Answer C: Ease off and pass the word forward so the group can respond
A rider missing from the line may have stopped or had trouble, and the group needs to know at once so it can slow down or pull over safely.
-
18. How does Iowa classify a first offense of operating while intoxicated?
Show answer
Answer A: A serious misdemeanor
Iowa Code section 321J.2 makes a first violation a serious misdemeanor, a second an aggravated misdemeanor, and a third or subsequent a class D felony.
-
19. You are making a U-turn at a signal on a green left arrow. Who must you still watch for?
Show answer
Answer D: People in the crosswalk you will cross as you come around
Even a protected arrow does not clear the crosswalk, and a U-turn sweeps across a crosswalk that pedestrians may already be using.
-
20. An overhead lane signal shows a flashing yellow X above your lane. What does it mean?
Show answer
Answer D: The lane may be used only for a left turn
A flashing yellow X marks a lane that may be used only to make a left turn; a steady yellow X is the one that warns you to leave the lane.
-
21. A broken white line separates your lane from the lane on your right. What does it permit?
Show answer
Answer C: Changing lanes when it is safe to do so
A normal broken white line marks a boundary between lanes traveling the same way that road users may cross when it is safe.
-
22. Are ordinary eyeglasses or sunglasses adequate eye protection for riding?
Show answer
Answer B: No, since they can shatter and let wind reach the eyes from the side
Everyday lenses are not made to resist impact and leave the eyes open to wind and debris, so a face shield or goggles are needed instead.
-
23. A bicyclist is riding around a single-lane roundabout in the middle of the lane as you wait to enter. What is your duty?
Show answer
Answer C: Yield to the bicyclist just as you would to a car
A bicyclist using the roundabout is traffic like any other vehicle and has the same claim to the circulating lane.
-
24. You reach a red light with a sign reading NO TURN ON RED. What may you do?
Show answer
Answer D: Wait for the green; no turn is allowed while the light is red
That sign removes the usual permission to turn on red at the intersection, so you must wait for a green indication.
-
25. You arrive at an intersection where the traffic signal is completely dark because of a power failure. How should you proceed?
Show answer
Answer C: Treat the intersection as an all-way stop
When a signal shows no indication at all, drivers on every approach must stop and then take turns, exactly as at an all-way stop.
