What is the recommended action regarding fog lights once visibility improves?

Turning off fog lights once visibility improves is the recommended action because fog lights are specifically designed to cut through thick fog, rain, or snow, providing a low, wide beam of light that minimizes the amount of light that is reflected back into the driver's eyes by the fog or precipitation. Once conditions have cleared and visibility has improved, keeping the fog lights on can create glare for other drivers and diminish overall road safety.

Using regular headlights is preferable in clear conditions, as they provide an appropriate range and focus for safe driving. Fog lights can become a distraction and even a hazard if used when not needed. Therefore, recognizing when weather conditions no longer require the use of fog lights is crucial for maintaining good driving etiquette and safety on the road.
