Are drivers allowed to use high beams in foggy conditions?

Using low beams in foggy conditions is the recommended approach to ensure safe driving. High beams can create a problematic situation in fog due to the way light is scattered. When high beams are activated, the light reflects off the water droplets in the fog, which can actually decrease visibility as it creates a glare and makes it harder to see the road ahead. Low beams, on the other hand, are designed to illuminate the road without causing excess glare, allowing for clearer visibility in adverse conditions such as fog and rain.

In addition, low beams direct light downwards, which minimizes the amount of light that is reflected back into the driver’s eyes, thereby improving safety and driving performance. This is why it is important to adjust your headlights based on weather conditions to ensure both your own visibility and that of other road users.
