What should you do if fog is reducing visibility while driving?

When driving in fog, visibility can be significantly impaired, making it crucial to adjust your driving technique and vehicle settings for safety. Using low beam headlights is the correct response in this situation because they are specifically designed to illuminate the road directly in front of you without reflecting off the fog. High beam headlights can actually worsen visibility in fog by causing light to scatter, creating glare that can make it harder to see.

Turning on hazard lights is not advisable as they are meant to indicate that your vehicle is stopped or experiencing an issue, rather than to improve visibility while driving. Driving faster to get through fog is also a dangerous approach; reduced visibility requires a slower speed to maintain control and react to any sudden obstacles or changes in conditions. This all emphasizes the importance of using low beam headlights to enhance visibility in foggy conditions while prioritizing safety on the road.
