During fog conditions, how can drivers best ensure they are seen by others?

Using fog lights and low-beam headlights is the best way for drivers to ensure they are seen by others during foggy conditions. Fog reduces visibility significantly, making it difficult for drivers to see the road ahead and for other road users to see a vehicle. Fog lights are designed to emit a wide, bar-shaped beam of light that can illuminate the road directly in front of the vehicle without causing glare in the fog. They can help enhance visibility in dense fog, and when used in conjunction with low-beam headlights, they improve a driver’s visibility and increase the likelihood that other drivers can see them. This is crucial for maintaining safety on the road in such challenging conditions.

The other methods have limitations: speeding past slower traffic can lead to dangerous situations, waving hands out of the window is not a practical or effective way to communicate presence on the road, and while turning on emergency flashers can signal a vehicle is in distress or moving very slowly, they are not primarily intended for use in fog and may not provide enough visibility to other drivers.
