2. A bicyclist is riding near the edge of your lane. Nothing has gone wrong, and you have not had to change speed or direction. In the manual's terms, what is the bicyclist?
Correct answer: A hazard
A hazard is a road condition or road user that could become a danger. It turns into an emergency only if something actually goes wrong, such as the rider cutting in front of you.

3. Besides giving you a poor view, what does the manual say headlights that point the wrong way can do?

4. Why does the manual tell you to communicate your presence to other drivers?
Correct answer: A vehicle can go unnoticed even though it is in plain view

5. Why must a trailer's landing gear handle be secured to the vehicle during travel?
Correct answer: A loose handle could swing out and hit other traffic
The crank handle has to be secured so that it cannot shift and hit other traffic. The gear itself must be fully raised so it does not strike the ground.

6. How does the manual suggest judging whether a distracted person near the road can see you?
Correct answer: Watch where the person is looking
Note the direction of a distracted person's gaze. Someone looking elsewhere cannot see you, and even someone looking at you may think they have the right of way.

7. In describing what the horn is for, which road users does the inspection guide name besides cars and pedestrians?
Correct answer: Motorcyclists and bicyclists

8. In fog you see taillights ahead of you. Why does the manual warn against treating them as a guide to where the road goes?
Correct answer: That vehicle could be stopped somewhere off the roadway
Lights ahead of you in fog may not show the true line of the road, because the vehicle they belong to might not be on it.

9. Why might a jogger or bicyclist on the road be unable to hear your vehicle, according to the manual?
Correct answer: They may be wearing a portable stereo with a headset
Walkers, joggers and bicyclists may have their backs to traffic and so cannot see you, and a headset can keep them from hearing you too.

10. According to the manual, what often blocks the vision of a delivery truck driver?
Correct answer: Packages or vehicle doors

11. At night your headlights can bother other drivers. When does the manual say to dim them?
Correct answer: Before the glare reaches other drivers
Lower your beams ahead of time, before glare reaches anyone: inside 500 feet of an oncoming vehicle or of one you are following.

12. Besides other drivers who are distracted, what does the manual say may get in your way in a work zone?
Correct answer: Workers and construction vehicles
Work zones bring narrower lanes, sharp turns and uneven surfaces, and workers or construction vehicles may move into your path. Drive slowly and carefully.
