6. A car ahead of you is headed for the freeway exit, but its brake lights come on and it starts braking hard. What does the manual suggest this could mean?

9. A car with luggage on its roof and out-of-state plates brakes for no clear reason in the middle of the block. What does the manual say these clues point to?
Correct answer: A tourist unfamiliar with the area, who may change direction or stop without warning
Roof luggage and plates from another state are clues to tourists, and stopping mid-block is a clue to confusion; confused drivers often change direction suddenly.

10. What does the manual say about noticing a tailgater from the seat of a large vehicle?

11. According to the manual, who is endangered when a driver's attention drifts away from driving?
Correct answer: The driver, any passengers, pedestrians and the other vehicles nearby

12. Why does the manual want you to spot other drivers who are distracted?
Correct answer: Failing to recognize them can keep you from perceiving or reacting in time to prevent a crash
Spotting a distracted driver early gives you time to respond; missing the signs can leave you unable to perceive or react soon enough.
