What does the use of fog lights require?

The use of fog lights requires that they must be turned off when visibility improves. Fog lights are specifically designed to illuminate the road immediately in front of the vehicle in low visibility conditions, such as when there is fog, heavy rain, or snow. When visibility improves, continuing to use fog lights can create glare and be distracting for other drivers, which is why they should be turned off to ensure safe driving conditions for everyone on the road.

While fog lights are essential in certain weather conditions, they are not necessarily mandatory in all foggy conditions, which aligns with the reasoning that they should only be used when needed. It’s also important to note that fog lights are not intended for use in rain at any time or during all night driving, as that could lead to inappropriate lighting that does not assist in ensuring safety.
