What should be done when driving in foggy conditions?

When driving in foggy conditions, using low beam headlights is crucial for safety. High beam headlights can cause the light to reflect off the fog, rain, or snow, creating a glare that reduces visibility instead of improving it. Low beam headlights provide a more effective illumination close to the road and help the driver see the pavement and nearby objects without the blinding glare associated with high beams.

In addition to improving visibility, it's also important to reduce speed in foggy conditions, as the reduced visibility may make it harder to see other vehicles, pedestrians, or road hazards. Ensuring that headlights are turned on is vital, as visibility is often reduced significantly during fog, and without headlights, it may be difficult for other drivers to see your vehicle as well.
