Use Fog Lights or Hazard Lights in Rain?
2 Answers
Whether to use fog lights or hazard lights in rain depends on different situations: 1. When visibility is less than 200 meters, turn on fog lights, keep the speed below 60 km/h, and maintain a distance of more than 100 meters from the vehicle ahead; 2. When visibility is less than 100 meters, turn on both fog lights and hazard lights, keep the speed below 40 km/h, and maintain a distance of more than 50 meters from the vehicle ahead. Fog lights are installed at the front and rear of the car. Because visibility is low in foggy conditions and the driver's line of sight is limited, the lights can increase the running distance, especially the strong penetration of yellow fog lights, which can improve the visibility of the driver and surrounding traffic participants, allowing oncoming vehicles and pedestrians to spot each other from a greater distance. Hazard lights are a signal to alert other vehicles and pedestrians that this vehicle is experiencing a special situation.
I've been driving for over a decade, and whenever it rains, I always choose to turn on my fog lights instead of hazard lights. The reason is simple: hazard lights are emergency signals used to alert others when your vehicle has a problem. Using them while driving normally in the rain can confuse other drivers into thinking you're about to stop, which can easily lead to rear-end collisions or chaotic accidents. Fog lights are specifically designed for low visibility conditions like rain or fog, providing steady illumination to enhance visibility. I still remember one time during a heavy downpour on the highway when I mistakenly used my hazard lights—later, an experienced driver corrected me, and I changed my habit. Now, I often advise new drivers to check their fog light functionality; during maintenance, clean the lamp covers and wiring to ensure the bulbs are in good condition. The core of safe driving lies in clear communication through light signals—don't misuse hazard lights for convenience, as it can lead to risks or fines. Driving slower in the rain and maintaining a safe distance are also crucial.
