Weather, Visibility & EmergenciesStandalone practice
At 10 a.m., you drive into thick fog. You can see only about 300 feet ahead. How should you use your lights?
A enters thick daytime fog on a two-lane road. Markings fade ahead, and no headlight beam or stopping response is selected.
Correct answer: Turn on your headlights on low beam, and slow down so that you can stop within your view.
Why
In fog or heavy rain, reduce your speed, increase your following distance and be ready to stop. Headlights also let other drivers see your car sooner, even in daylight. If the fog gets so thick that you have no safe view ahead, leave the road and stop until you can see better.
