When driving in fog, what adjustment should you make to your headlights?

When driving in fog, it is crucial to switch to low-beam headlights. This is because high-beam headlights can create significant glare that reflects off the fog, reducing visibility rather than enhancing it. The light is projected further ahead, but in foggy conditions, it bounces back at the driver, creating a white wall effect that makes it difficult to see the road ahead.

Low-beam headlights, on the other hand, are designed to provide sufficient illumination of the road without causing excessive glare. They project light downward and limit the amount of light that reflects back at the driver, improving visibility in foggy conditions. Using low beams allows you to see the road better and helps other drivers see you as well.

Turning off the headlights entirely or relying solely on fog lights can compromise your safety, as you would have insufficient visibility of the road ahead or might not be visible to other vehicles. Therefore, utilizing low-beam headlights is the optimal choice when navigating through fog.
