If you have trouble seeing other vehicles because of dust or smoke blowing across the roadway, you should drive more slowly and turn on your:
- Emergency flashers.
- Parking lights.
- Headlights. ✓
Answer: C. Headlights.
Slow down and turn on your headlights so you can see better and other drivers can see you.
Why this is the answer
The manual explains that when rain, fog or snow make it hard to see through your windshield, it is also hard for other drivers to see you, and New York law requires headlights whenever conditions call for windshield wipers. It adds that low beams work better than high beams in these conditions because high beams reflect the rain, fog and snow back at you. Dust or smoke cutting visibility works the same way, so the manual's advice is to reduce speed and switch on your headlights, kept on low beam.
Why the other answers are wrong
- A. Emergency flashers. — Emergency flashers are not what the manual directs you to use for poor visibility; its instruction is to slow down and use headlights.
- B. Parking lights. — Parking lights are not headlights, and the manual makes the point that lights which do not qualify as headlights are not enough in conditions that limit visibility.
Remember it
If you need the wipers or you cannot see far ahead, your low-beam headlights should be on, not just your parking lights.
