Should Fog Lights Be Turned On in the Rain?

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.

What annoys me most while driving is encountering novice drivers who don't know when to use lights, especially during rainy days. For light rain, there's no need to use fog lights - low beams combined with position lights are sufficient. But during heavy downpours, fog lights stand out like fireflies in the night, making your vehicle visible to following cars 3-4 seconds earlier. Once on the highway during sudden heavy rain, I immediately turned on my rear fog lights, and the truck driver behind actually honked to thank me for the warning. The fog light switch is on the left knob near the steering wheel - look for the bulb icon with wavy lines. Timing matters when using fog lights - if the rain stops and visibility improves, remember to turn them off promptly as they can be blinding. By the way, always fasten seatbelts front and rear - roads get slippery when wet.

Actually, whether to turn on fog lights depends on the situation. My car's automatic headlights turn on when it rains, but the fog lights require manual control. For light drizzles, there's no need to turn them on, but when visibility drops below 100 meters, the fog light system should be activated. Once in a narrow alley with heavy fog and rain, turning on the fog lights helped me spot pedestrians standing by the roadside. Note that rear fog lights are three times brighter than brake lights, which can be dazzling for following vehicles if they're too close, so maintaining a safe distance is crucial. When using fog lights in the rain, it's also advisable to close the windows tightly and turn on the air conditioning to defog, especially when the windshield fogs up—the AC dehumidification mode works best. Safe driving requires comprehensive consideration of lighting and vehicle conditions.

As a frequent long-distance driver, I've mastered the rules for using lights in rainy weather. When visibility is decent in drizzling rain, low beams are sufficient. But during heavy downpours when wipers are at their fastest setting, it's time to activate the fog lights. The bright red rear fog lights have exceptional penetration - visible from 200 meters away even in torrential rain. Note the fog light indicator on the dashboard to avoid confusing it with other lights. Once on winding mountain roads during sudden rain, I clearly noticed following vehicles keeping greater distance after turning on fog lights. With reduced tire grip in rain, it's safest to lower speed by 20% when using fog lights. Always remember to turn them off afterward - I once forgot and got flashed by a driver behind me.

I think whether to turn on the fog lights in the rain depends on the degree of white haze in front of you. If the taillights of the car ahead start to blur, you must turn on the fog lights. Fog lights are not decorations; their red light source penetrates the rain curtain much better than hazard lights. Remember to rotate the fog light switch all the way to the position marked 'ON.' A common mistake beginners make is turning on the front fog lights but not the rear ones, when in fact, the rear fog lights are more important. Once on a cross-sea bridge during a sudden heavy downpour, cars with rear fog lights on were noticeably easier to spot than those without. Also, a reminder: try not to change lanes when the fog lights are on; driving straight is the safest. Driving in the rain boils down to these nine words: 'turn on lights early, drive slowly, and keep a long following distance.'
