-
6. You park at the roadside on a hill, facing downhill. What keeps the motorcycle from rolling away?
Show answer
Answer D: Leaving it in first gear with the front wheel turned toward the curb
A motorcycle has no parking brake, so the transmission left in gear stops the wheel turning and the front wheel turned into the curb blocks any roll.
-
7. After turning right you see a sign showing that your lane ends a short way ahead. What should you do?
Show answer
Answer B: Signal and merge into the next lane while there is still room
Merge early and smoothly while a gap is still available, rather than running out of pavement or forcing your way in at the last moment.

10. You are driving on a rural road with no sidewalk. Where should you expect to meet pedestrians?

-
11. The school bus stop ahead sign is installed where
Show answer
Answer C: a school bus stop cannot be seen from far enough away by approaching drivers
This school warning sign is used in advance of a bus stop that lacks adequate sight distance and cannot be relocated, so drivers are warned before the stopped bus comes into view.
-
12. You cannot avoid an obstacle lying in the road. At what angle should you try to cross it?
Show answer
Answer D: As close to 90 degrees as possible
Meeting the obstacle squarely keeps the front wheel from being deflected sideways as it climbs over the edge.

-
16. What does the Iowa electronic device statute say the word use includes?
Show answer

-
17. You are waiting to turn and the traffic ahead has stopped. Where must you not come to rest?
Show answer
Answer D: On the crosswalk, which people need in order to cross the street
Stopping on a crosswalk forces pedestrians out into the traffic lanes to get around you, so you hold back before it instead.
-
18. A snow squall cuts visibility to almost nothing while you are on a highway. What must you not do?
Show answer
Answer D: Stop in a travel lane and wait for the squall to blow through
A vehicle stopped in a lane in a whiteout is invisible until someone hits it. Slow gradually and keep moving until you can leave the roadway completely.
-
19. A driver is following your motorcycle much too closely. What should you do?
Show answer
Answer B: Ease off the throttle and open more space ahead so the driver can pass
Slowing gradually and opening a bigger gap in front encourages the tailgater to pass and gives the rider room to stop gently instead of hard.
-
20. A speed limit sign carries a second panel reading TRUCKS 55. What does that panel do?
Show answer
Answer B: It sets a lower legal limit for trucks
A truck speed limit panel is regulatory, so trucks are bound by the lower figure while other traffic keeps to the main limit.
-
21. You leave a brightly lit service area onto a dark rural road. Why should you slow down for a while?
Show answer
Answer C: Your eyes need time to adjust, so at first you see less
Eyes take a few minutes to adapt from bright light to darkness, and during that time you can see much less than your headlights actually show.
-
22. 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.
-
23. 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.

24. What does a pre-ride check of a hydraulic brake system cover?

-
25. You are turning right where a paved trail crosses the road just past the corner. What should you look for?
