Why Shouldn't You Turn on Fog Lights on Rainy Days?

[McJuliette]

Lights should be used according to regulations on rainy days. Here are the relevant explanations: Position lights: The type of light to use should be determined based on visibility. For example, when it just starts to rain and the sky is relatively dark but visibility is still good, position lights should be used. Front fog lights: When the rain is heavier, the rainwater itself can obstruct the view, and the water on the road surface splashed by the rolling tires of the vehicle ahead can create a mist, significantly affecting visibility. In such cases, headlights or front fog lights should be turned on. Rear fog lights: Rear fog lights should only be turned on during very heavy rain because the red taillights already have excellent penetration, and ordinary heavy rain cannot block their light. Rear fog lights are very bright and are designed to penetrate thick fog.
