2. Why is a wet road at night harder to read than the same road in daylight?
Show answer
Answer A: The wet surface reflects light away and swallows the lane markings
A film of water sends your headlight beam onward instead of back to you, so lines, edges and people in dark clothing almost disappear.

Show answer
Answer D: The peace officer, although refusing the blood test alone is not treated as a refusal

-
8. The sun is low behind you and shining into the eyes of oncoming drivers. What should you do?

-
12. You are waiting to enter a two-lane roundabout and traffic is circulating in both lanes. What must you do?
Show answer

Every entry to a roundabout is a yield point, and at a two-lane roundabout that means giving way to vehicles in either circulating lane.
-

-
15. May you exceed the posted speed limit in order to complete a pass?
Show answer
Answer C: No, the posted limit applies while you are passing too
The limit does not lift for passing; if you cannot complete the pass within it, there is not enough room and you should stay back.
-
16. On a long uphill grade a second lane opens on the right and a sign directs slower traffic into it. You are towing a trailer and holding up a line of vehicles. What should you do?
Show answer
Answer A: Move into the right-hand lane and let the faster traffic use the left lane
A climbing lane exists so that slow vehicles can be passed safely, and the slower vehicle is the one that belongs in it.
-
17. At a stop sign with a painted stop line and a crosswalk, where must you stop?
Show answer
Answer D: At the stop line, before it and before the crosswalk
You stop at the stop line first, and only if there is no stop line do you stop before the crosswalk, and only if there is neither do you stop before entering the intersection.
-
18. You have brought the vehicle under control after a blowout. What should you do next?
Show answer
Answer A: Signal and coast well off the road before stopping
Let the speed fall, signal, and leave the roadway as far from traffic as you can before you stop. Driving on a failed tire ruins the wheel and risks control.
-
19. A driver who is passing you cannot complete the pass because a vehicle is coming. What should you do?
Show answer
Answer C: Ease off the accelerator and make room for them to drop back in
The only place for the passing vehicle to go is the gap behind you, and easing off opens that gap immediately.
-
20. Someone has stepped into a marked crosswalk in the middle of a block ahead of you. What should you do?
Show answer
Answer A: Slow down, stop before the markings and let the person cross the street
A marked mid-block crosswalk carries the same duty as one at a corner: give way to the person crossing, stopping if that is what letting them cross safely takes.
-
21. Your right wheels drop off the edge of the pavement onto a soft shoulder. What should you do?
Show answer
Answer C: Ease off the accelerator, hold the wheel straight and steer back gently once you have slowed
Yanking the wheel while the tires are pressed against a pavement lip can throw the vehicle across the road, so slow down first and then make a gentle correction.
-
22. There is a driveway and a side street between you and the corner where you will turn right. When should you signal?
Show answer
Answer C: After passing the openings, so nobody pulls out in front of you
A signal switched on before an opening tells drivers waiting there that you are turning in, and they may pull out into your path.
-
23. After an hour on a hot highway your tire pressure reads higher than it did in the morning. What should you do?
Show answer
Answer D: Nothing, because pressure rises when tires heat up
Air expands as the tire warms, so a hot reading is normally above the cold setting. Bleeding air off would leave the tire underinflated once it cooled.
-
24. What speed limit applies on Iowa fully controlled-access, divided, multilane highways that are not part of the interstate system?
