Which lights should you utilize when driving in fog?

When driving in fog, it is essential to use low beams or fog lights because they are designed to provide better visibility under such conditions. High beams tend to reflect off the moisture in the air, creating a glare that can actually reduce your visibility, making it harder to see the road and any obstacles ahead. In contrast, low beams and fog lights are specifically aimed at illuminating the road immediately in front of your vehicle without causing excessive glare, allowing you to see better in dense fog.

Fog lights are particularly beneficial as they emit a wider and shorter beam pattern that helps illuminate the road close to your vehicle without pushing light into the fog, which can lead to reflections and decreased visibility. This ensures that drivers can see better without compromising their vision or that of oncoming traffic.

Using emergency lights is designed for signaling a breakdown or an emergency situation, and daytime running lights, while they increase vehicle visibility to other drivers, do not provide sufficient lighting for the driver to see the road and surroundings in foggy conditions. Therefore, the best practice is to stick with low beams or fog lights while navigating through fog.
