# Explanation
When there is a cloud of smoke that reduces visibility, you must turn on the front fog lights or the short/long-range lights, regardless of whether it is daytime or what time it is. This improves your visibility to other drivers and allows you to see the road better in low-visibility conditions. The use of lighting is mandatory whenever there are visual obstacles; it does not depend on whether vehicles are coming from the opposite direction.
