Should Fog Lights Be Turned On in the Rain?
2 Answers
When the rainfall is heavy, you should turn on the headlights or front fog lights. In case of a downpour, the rear fog lights can be activated. For light rain, use the position lights. Precautions for driving in the rain: 1. Slow down: Visibility is low and vision is poor in rainy conditions. The emergency performance of the vehicle, such as braking distance, is also reduced, so it is necessary to slow down in advance, leaving enough time and space to handle situations and ensure safety. 2. Maintain distance: Driving in the rain obstructs vision, so it is important to keep a safe distance between vehicles, constantly observe the distance from the car in front and behind, and increase the safety margin. 3. Do not restart after stalling: In heavy rain or stormy weather, some road sections may become severely waterlogged in a short time. If you must drive through water, do so at a steady speed using a low gear. If the vehicle stalls while moving, never attempt to restart it immediately. Blindly restarting could cause the engine to be irreparably damaged. After the vehicle stalls, contact a professional repair shop promptly. Only after a technician has inspected the vehicle on-site and confirmed there are no issues should you attempt to restart it.
Speaking of whether to turn on fog lights in the rain, with twenty years of driving experience, I have deep insights. When the rain is not heavy, using regular low beams is completely sufficient—just remember to increase the wiper speed and turn on the rearview mirror heating. If the rain is pouring so heavily that you can't see clearly ten meters ahead, then fog lights are a must. Rear fog lights have particularly strong penetration, allowing vehicles behind to spot our position from far away. However, it's worth noting that not all cars come equipped with front fog lights; if yours does, they can provide auxiliary lighting during heavy downpours. Another detail: the drizzly, misty weather during the humid spring season is actually the most dangerous—the combination of fog and rain reflection is most prone to accidents, so fog lights should be turned on promptly in such conditions. The key is to avoid using high beams, as water vapor reflection can create a blinding whiteout.
