How to Use Lights Correctly When Driving in Foggy Weather?
3 Answers
Correct methods for using lights when driving in foggy weather: 1. Turn on both front and rear fog lights. 2. Activate the hazard warning lights (double flashing lights). 3. Turn on the low beam headlights when visibility is poor. When driving at night without streetlights, under poor lighting conditions, or in low visibility situations such as fog, rain, snow, dust, or hail, vehicles should turn on the headlights, position lights (side markers), and tail lights. However, high beam headlights should not be used when a following vehicle is driving close behind another vehicle in the same direction. Below are precautions for driving in foggy weather: 1. Use vehicle lights appropriately in heavy fog. 2. Pay attention to speed limits. 3. Apply the brakes frequently and gently while driving. 4. Use the horn often. 5. Choose driving routes carefully. 6. Pull over and stop when necessary. 7. Use defogging techniques for the front windshield. 8. If stranded due to heavy fog, wait until visibility fully recovers before continuing to drive.
I've been driving for twenty years and often take long trips in foggy weather. The most crucial thing about fog lights is to turn on the low beams and front fog lights—never touch the high beam switch, as high beams reflect off the fog and dazzle your eyes. The rear fog light must also be on; its bright red glow allows vehicles behind to spot you earlier, avoiding rear-end collisions. In heavy fog, I slowly move with hazard lights on, but remember not to keep them on continuously—use them briefly only when visibility is extremely low. Reduce your speed to about half of your usual pace, maintain a following distance of at least 50 meters, and avoid tailgating. Make it a habit to check if your fog lights are working before every trip—a broken light is like being invisible in the fog. Cleaning the windshield is also essential; wipers and washers help keep your vision clear. Safety always comes first—most fog-related accidents happen due to incorrect light usage or excessive speed. I always remind beginners not to rush and wait for the fog to clear before continuing their journey.
I just got my driver's license not long ago, and my first time driving in fog was terrifying. My driving instructor emphasized: just turn on the low beams, don't foolishly use the high beams—that strong light reflects off the fog and makes it impossible to see anything. Always turn on the front and rear fog lights—the yellow front fog lights penetrate well, and the red rear fog lights are highly visible to prevent rear-end collisions. Once, I accidentally turned on the high beams, and the blinding whiteness almost made me hit a tree—scared me to death. Since then, I've followed the rules: use fog lights in light fog and hazard lights in heavy fog, moving forward cautiously. Drive at a snail's pace and maintain a following distance twice the usual safe gap. Keep a bottle of defogger in the car to clean the windows, and use phone navigation as an aid but don't stare at it. As a beginner, practicing a few times in foggy conditions will help you get used to it—using the correct lights makes the journey much smoother. Before heading out, make a habit of testing all the light switches to ensure they work properly—don't get caught off guard.
