What is the purpose of front fog lights on a car?

The purpose of front fog lights: Front fog lights are installed on the front of the car, slightly lower than the headlights, and are used to illuminate the road during rainy or foggy weather. They generally emit yellow light, as yellow is a color with strong penetrating power. The yellow fog lights of a car can penetrate thick fog and reach far distances, improving visibility for the driver and other traffic participants. The role of front fog lights is to make the vehicle visible to other cars in conditions where visibility is significantly affected by weather, such as fog or heavy rain, thereby reducing the risk of severe accidents like chain collisions in low-visibility conditions. The symbol for front fog lights consists of three diagonal lines crossed by a curved line on the left and a semi-elliptical shape on the right.
I remember driving back to my hometown during a heavy snowstorm. The road was completely white, and the regular headlights just reflected off the snow, making it impossible to see anything. That's when the front fog lights came in handy. Positioned low and with a diffused beam that doesn't shine directly, they cut through the snow and fog, illuminating the road ahead so I could spot road signs and potholes. They're just as useful in rainy or foggy conditions—when rain causes strong glare, turning them on helps avoid blinding reflections and improves safety. But don't overuse them; remember to turn them off once the fog clears, as leaving them on can be impolite and dazzle other drivers. With twenty years of driving experience, this habit has helped me avoid many accidents. When driving in low-visibility conditions, turning them on is a smart move—safety always comes first.
