Weather, Visibility & EmergenciesStandalone practice
At noon, thick fog lets you see other vehicles clearly only about 300 feet ahead. Your car's daytime running lights are on. What should you do about your lights?
A travels through thick daytime fog. The view contains no illustrated headlight beam and the card gives the existing daytime-running-light condition.
Correct answer: Turn on your headlights, because you cannot see clearly for 1,000 feet
Why
In fog, headlights help other drivers see you, and they turn on the taillights for drivers behind you. The guide says to have your headlights on when it is rainy, snowy, foggy or smoky. Also increase your following distance, because you have less time to see a hazard.
