At dusk or on overcast days, you should:
- Drive using your four-way flashers.
- Drive using your parking lights.
- Not turn on any vehicle lights.
- Turn on your headlights. ✓
Answer: D. Turn on your headlights.
Turn on your headlights.
Why this is the answer
The manual tells you to switch on headlights at dawn and dusk and in fog, and it treats low-light periods as times when your vehicle needs to be easy for others to spot. It also says headlights are better than parking lights or daytime running lights for this purpose. Overcast conditions reduce visibility, so the same lighting rule applies. That is why the correct choice is to turn on your headlights.
Why the other answers are wrong
- A. Drive using your four-way flashers. — The handbook does not present four-way flashers as a low-light lighting choice; it points you to headlights so others can see you.
- B. Drive using your parking lights. — The manual specifically says not to use parking lights as a replacement for headlights, because headlights do a better job.
- C. Not turn on any vehicle lights. — Driving with no lights leaves you hard for other drivers and pedestrians to see, which is exactly what the manual says headlights help prevent.
Remember it
Think "dusk, dawn, fog, gray sky: headlights on." Parking lights do not count.
