Under what circumstances should car fog lights be turned on?
2 Answers
Car fog lights are used in foggy or rainy conditions when visibility is significantly affected by the weather. The prerequisite for turning on the fog lights is to first turn on the vehicle's lights, and then press the fog light button. Fog lights are lighting signals used in rainy or foggy weather. Fog lights are installed at the front and rear of the car to illuminate the road and remind vehicles ahead and behind to maintain a safe distance during rainy or foggy weather driving. The visible range of vehicle headlights is generally only within 30 to 50 meters, while the visible range of fog lights can reach about 100 meters. Fog lights are used during heavy rain when the windshield is covered with water, causing blurred vision and difficulty in seeing the distance from vehicles ahead and behind. In such cases, fog lights can be turned on to alert other vehicles and avoid collisions.
The best time to turn on your car's fog lights is during severe weather conditions, such as heavy fog when visibility is obscured by a white haze, and regular headlights tend to reflect, making it harder to see the road. Once, I was driving home at night in thick fog and could barely see a few meters ahead. I promptly turned on the fog lights, which are positioned low and emit a yellow light with strong penetration, helping me clearly identify lane markings and avoid a rear-end collision—it was incredibly practical. They are also useful during heavy rain, especially on highways when sudden downpours drastically reduce visibility. Fog lights make your vehicle more noticeable to others. They are equally effective in snowy conditions or strong smoke environments. Remember, never use fog lights on clear nights—their intense brightness can dazzle oncoming drivers, creating glare hazards. Develop the habit of using fog lights only when the road is slippery or visibility is poor, ensuring both your safety and consideration for others.
