1. Windblown sand has collected across the pavement at a rural intersection where you must stop. How should you handle the stop?
Show answer
Answer A: Do your braking on clean pavement before the sand, then roll across upright
Sand acts like ball bearings under the tires, so finish your braking on the clean surface ahead of it and cross the loose patch upright with no sudden inputs.
-
2. Why does a motorcycle with a manual fuel supply valve have an OFF position?
Show answer
Answer A: It stops fuel reaching the engine while the machine is parked
Shutting the valve keeps fuel from seeping past the carburetor into the engine or onto the ground while the motorcycle stands unused.
-
3. A friend who has been drinking insists on driving home. What is the right thing to do?
Show answer
Answer B: Take the keys and arrange a sober ride, even if the friend objects
An impaired driver is dangerous on any street at any speed, and coffee does not lower blood alcohol. Keeping the keys and finding another way home is the only safe choice.
-
4. The front tire suddenly loses air while you are riding. What should you do?
Show answer
Answer D: Hold the bars firmly, ease off the throttle and slow using the rear brake
A deflating front tire makes the steering feel heavy, so the rider keeps a straight line, avoids the affected wheel when braking and eases off the road.
-
5. A clutch cable adjusted with no free play at all causes what problem?
Show answer
Answer B: The clutch may slip and never fully engage
Without a small amount of slack the release mechanism keeps a light load on the plates, so they slip instead of transmitting full power.
-
6. A yellow horizontal rectangular sign showing one large arrow pointing left or right, facing traffic on the far side of a sharp bend, tells the driver
Show answer
Answer C: which way the roadway turns at that point
The large arrow sign is mounted on the outside of a sharp change in alignment so that a driver approaching head on immediately sees which way the road goes.
-
7. What should a rider do before riding an unfamiliar or borrowed motorcycle?
Show answer
Answer B: Locate and try the controls, then ride cautiously until used to the machine
Turn signals, horn, headlight switch, fuel valve and engine cut-off switch sit in different places on different models, and hunting for them in traffic is dangerous.
-
8. Is a windshield an adequate substitute for eye protection?
Show answer
Answer A: No, because air and debris still reach the rider's eyes around and over the screen
Airflow passes over and around a windshield, so a face shield or goggles are still needed to keep the rider's vision clear.
-
9. For how long after an Iowa driver's license expires may it be renewed without a driving test or written examination?
Show answer
Answer B: One year
Iowa Code section 321.196 makes a driver's license renewable without a driving test or written examination within a period of one year after its expiration date.
-
10. What actually lowers the amount of alcohol in a person's blood?
Show answer
Answer D: The passage of time
The body eliminates alcohol at its own steady rate, so only time reduces blood alcohol. Coffee or a cold shower may make a person feel more awake while still impaired.
-
11. When is passing another vehicle on the right generally permitted?
Show answer
Answer C: When the road has two or more lanes in your direction, or the vehicle ahead is turning left and there is room without leaving the pavement
Passing on the right is limited to situations where a lawful lane exists for it or the vehicle ahead is turning left, and it may never be done by driving onto the shoulder.
-
12. You are the second vehicle waiting to turn left on a green ball. Where should you wait?
Show answer
Answer A: Behind the stop line, until the first vehicle has actually turned
Only the lead vehicle should move into the intersection to wait; a second vehicle inside it is likely to be stranded there when the light changes.
-
13. In a normal signal cycle, what comes after a steady red indication?
Show answer
Answer A: A green indication that starts the next movement
Yellow is a warning that a movement is ending, so it never precedes a green; a red is followed by a green or a green arrow.
-
14. An overhead lane-use control signal shows a steady red X above your lane. What does it mean?
Show answer
Answer B: You may not use that lane and must move out of it
A steady red X means the lane below it is closed to you, while a steady yellow X is the warning to prepare to vacate the lane and a downward green arrow means the lane is open.
-
15. You are about to accelerate hard to merge with traffic. What should you have arranged with your passenger?
Show answer
Answer D: That you warn them beforehand so they can tighten their grip
A passenger who is not expecting a burst of acceleration is thrown backward, and the sudden shift of weight upsets the machine just when the rider needs it settled.
-
16. Your road ends at a T-intersection with no signs or signals. Who has the right-of-way?
Show answer
Answer A: Traffic on the through road, and you must yield before entering
A driver on a road that ends at a T-intersection must yield to traffic on the through road that continues past the junction.
-
17. Along a highway the reference markers count upward as you travel. Where does the numbering normally begin?
Show answer
Answer C: At the southern or western edge of the state
Mileage numbering starts where the route enters the state from the south or the west, so rising numbers tell a driver which way they are heading.
-
18. You are turning left from a divided highway through a median opening into a business on the other side. Who has the right of way?
Show answer
Answer C: The traffic on the roadway you are crossing
Turning through a median opening means crossing the opposite roadway, so you yield to all traffic on it before you go.
-
19. You are in the middle of an intersection when you hear a siren and see an emergency vehicle approaching. What should you do?
Show answer
Answer A: Keep going, clear the intersection, then pull to the right and stop
Stopping inside an intersection blocks the emergency vehicle. Clear the intersection first, then pull over to the right and stop.
-
20. Why is wearing headphones over both ears a problem while driving?
Show answer
Answer D: You may not hear horns, sirens or other warning sounds
Hearing is part of your awareness of traffic. Covering both ears blocks emergency sirens, horns and the sound of an approaching vehicle you cannot yet see.
-
21. Which clue tells you that a parked vehicle is about to pull into traffic?
Show answer
Answer D: Exhaust smoke, brake lights, front wheels turned out or a driver in the seat
A running engine, lit brake lights, turned wheels or a person behind the wheel all mean the vehicle may move. Slow down and give it room.
-
22. A sign with a green background and a white legend normally provides
Show answer
Answer A: directions, distances and destinations
Green is the background color of the guide sign series, which names routes and destinations and gives the distance to them.
-
23. Your vehicle has broken down at night on a rural road and your phone has no signal. What is the safest thing to do?
Show answer
Answer C: Stay with the vehicle, keep the hazard lights on and wait for help
A lit vehicle is far easier to find than a person walking in the dark, and running the engine while you sleep risks carbon monoxide.
-
24. You arrive at an intersection where the traffic signals are completely dark after a power failure. What should you do?
Show answer
Answer A: Treat the intersection as an all-way stop and take turns
When a signal is dark or out of order, drivers on every approach must stop and proceed in turn, exactly as at a four-way stop.
-
25. When is it safe to return to your own lane after passing a vehicle?
Show answer
Answer C: Once you can see the whole front of that vehicle in your mirror
Seeing the entire front of the vehicle in the mirror proves there is a full vehicle length of clear road, which the rider cannot judge by feel alone.
