What is the appropriate action when driving in foggy conditions?

When driving in foggy conditions, using low beam headlights is the most appropriate action. Low beams are designed to provide better visibility in such weather conditions because they reduce glare that can bounce off the fog, rain, or snow. High beams can actually impair visibility because they reflect off the moisture in the fog, producing a blinding effect, which can make it even more difficult to see the road and other vehicles.

The use of low beams helps illuminate the road directly ahead and keeps the lights lower to the ground, allowing drivers to see better without causing significant glare. This practice is not only safer but also helps in maintaining control of the vehicle in reduced visibility conditions typically present during fog. It’s also important to adjust driving speed according to visibility, ensuring that safety remains a priority.
