1. You have had to leave the pavement onto a loose gravel shoulder and now need to stop. How should you brake?
Show answer
Answer D: Use both brakes gently and evenly, expecting a much longer stopping distance
Loose gravel cuts available traction sharply, so apply both brakes lightly and smoothly and allow far more room than you would need on pavement.
-
2. Which of the four blind spots around a tractor-trailer is the largest?
Show answer
Answer A: The one on the right side of the truck
A truck has no-zones on all four sides, and the right-side blind spot is the largest because it runs back along the trailer and reaches across more than one lane.
-
3. What is a manageable size for a single group of motorcycles?
Show answer
Answer A: No more than four or five riders
Four or five machines can hold a formation, stay in sight of one another and clear an intersection together, while larger groups quickly become unmanageable.
-
4. What is a good rule for any task you want to do inside the vehicle?
Show answer
Answer D: If it needs more than a moment, do it stopped
A glance of a second or two is manageable, but any task that runs longer belongs to a stopped vehicle, because the road does not pause while you do it.
-
5. You realize you have just gone past your exit on a freeway. What should you do?
Show answer
Answer C: Carry on to the next exit and turn around there
A missed exit costs a few minutes, while backing up or cutting across the striped gore area puts you in the path of traffic that is not expecting it.
-
6. You are on a city street with two lanes in your direction, cars parked along the curb and driveways every few yards. Which lane is usually safer?
Show answer
Answer B: The lane farther from the curb, away from opening doors and vehicles pulling out
Most of the hazards on such a street come from the curb side, so the inside lane gives you more space and more time to react.
-
7. You are involved in a collision, even a minor one. What is your first legal duty?
Show answer
Answer A: Stop at or near the scene without blocking traffic more than necessary
Every driver involved in a crash must stop at the scene, and leaving before meeting that duty is a serious offense. Move the vehicles only as far as needed to clear the traffic lanes.
-
8. What is sensible when you drive in an unfamiliar town for the first time?
Show answer
Answer C: Drive a little slower and give yourself more time to read the signs
In unfamiliar surroundings you need longer to take in signs, junctions and markings, and lower speed buys that time.
-
9. 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.
-
10. Where should the rider be looking during a U-turn?
Show answer
Answer B: All the way around toward the point where the turn will finish
A motorcycle follows the eyes, so turning the head to the exit of the turn keeps the machine coming round instead of drifting wide.
-
11. Where are signs of this kind placed at an intersection?
Show answer
Answer C: At the near right and far left corners, facing drivers on the intersecting street
They are installed at the corners of the intersecting street so that a driver about to turn in sees the restriction before committing to the turn.
-
12. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
13. You are riding on a multi-lane road with a car traveling beside you in the lane on your right. Which lane position is usually best?
Show answer
Answer D: The left portion, so you keep a cushion of space from the car alongside
Lane position is chosen to hold space between the motorcycle and the nearest hazard, and here that hazard is the vehicle on the right.
-
14. When should gear changes for a turn be completed?
Show answer
Answer A: Before entering the turn, so the machine stays settled through it
A clumsy shift while leaned over can jerk the rear wheel and break traction, so the right gear should be selected before the lean begins.
-
15. A large X with the letters R and R beside it is painted across your lane. What does it mean?
Show answer
Answer A: A railroad crossing lies a short distance ahead
The pavement marking repeats the advance warning for a grade crossing, and it is used on paved approaches where speeds are high or where gates are installed.
-
16. Can a driver be charged with impaired driving after taking a legal over the counter medicine?
Show answer
Answer C: Yes, if the medicine impairs the ability to drive safely
Impaired driving laws cover any substance that affects driving, including cold remedies, allergy pills and sleep aids sold without a prescription.
-
17. Two vehicles reach a four-way stop at the same moment from adjacent roads. Who should go first?
Show answer
Answer A: The driver on the right
When two drivers stop at a four-way stop at the same time, the driver on the left yields to the driver on the right.
-
18. Does wearing properly fitted earplugs stop a rider from hearing important sounds?
Show answer
Answer C: No, they lower overall noise while horns and speech still register
Earplugs reduce the wind roar that masks everything else, so riders wearing them often hear traffic more clearly, not less, while their hearing is protected.
-
19. A driver's destination lies along the street to the right, and this sign stands at that corner. How should the driver reach it?
Show answer
Answer D: By going on and using a later intersection where turning is allowed
When a movement is barred at one corner the driver has to reroute, normally by continuing and coming back to the destination from a permitted approach.
-
20. For how long is an Iowa driver's license valid only for operating a motorized bicycle issued?
Show answer
Answer D: Two years
Iowa Code section 321.189 makes a license valid only for operation of a motorized bicycle effective for a period not to exceed two years from the licensee's birthday anniversary in the year of issuance.
-
21. What is the main function of the guide sign series?
Show answer
Answer D: To identify routes and lead road users to their destinations
Guide signs identify routes, name destinations and give distances, so drivers can navigate without stopping to consult a map.
-
22. What does research say about the effect of a full coverage helmet on a rider's ability to see and hear traffic?
Show answer
Answer B: It leaves the view and the useful hearing a rider needs largely intact
Certified helmets leave far more peripheral vision than a rider needs to check traffic, and riders wearing them still hear the sounds that matter.
-
23. Why can a mild afternoon still chill a rider dangerously on the highway?
Show answer
Answer B: Riding speed creates a wind chill well below the air temperature
Air moving over the body at highway speed strips heat far faster than still air, so a comfortable temperature at a standstill can cause serious chilling in an hour of riding.
-
24. How many alcoholic drinks does it take to begin affecting driving ability?
Show answer
Answer C: Even one drink can affect it
A single drink can slow reactions and weaken judgment before you feel any change. Impairment starts long before a person feels drunk.
-
25. When must a passenger keep both feet on the footrests?
Show answer
Answer C: At all times, including while the motorcycle is stopped
Feet stay on the footrests even at a stop, because a foot put down or swung out can unbalance the motorcycle or be caught by the road.
