When driving on major highways:
- Stay alert.
- Keep your eyes moving.
- Be ready to react to road hazards.
- All of the above. ✓
Answer: D. All of the above.
When driving on major highways, all of the above apply: stay alert, keep your eyes moving, and be ready to react to road hazards.
Why this is the answer
The handbook's defensive driving list ties these habits together. It says the defensive driver should stay alert and keep eyes moving to track what is happening at all times, look for trouble spots developing all around, and have a plan of action. Staying alert and scanning the road are stated directly, and looking for developing trouble spots is what puts you in position to react to hazards. Since the handbook presents them as one set of habits rather than separate choices, the combined answer fits best.
Why the other answers are wrong
- A. Stay alert. — Staying alert is only one item on the handbook's defensive driving list, not the whole of it.
- B. Keep your eyes moving. — Keeping your eyes moving is named in the handbook, but it is listed alongside other habits rather than by itself.
- C. Be ready to react to road hazards. — Being ready to react to hazards grows out of watching for trouble spots, so it is part of the same set and not the complete answer.
Remember it
Treat defensive driving as a package deal: alert mind, moving eyes, and a plan already in your head.
