How to drive in foggy weather

"When driving a vehicle in foggy days, you must drive at a low speed. When the visibility is about 10 meter, the speed should be below 5 kilometers per hour. In addition, fog lights, low beam lights and rear lights should be turned on when driving in foggy days, but remember not to turn on the high beam lights, because the high beam lights are very strong and will be reflected into the driver's eyes by fog. At the same time, honk the horn frequently when driving to warn pedestrians and vehicles. When you hear the horn of an oncoming car, you should whistle back to show the position of your car. You can turn on and off the lights to indicate the meeting. The safest way to drive in foggy days is to turn on the low beam, width indicator and taillight when the visibility is 200 -500 meters in foggy days. The speed shall not exceed 80km/h, and the driving distance shall be kept above150m. When the visibility is 100 m -200 m, turn on the anti-fog lamp, low beam lamp, width indicator lamp and tail lamp, the speed shall not exceed 60 km/h, and the distance between vehicles shall be kept above 100 m; When the visibility is between 50 meters and 100 meters, the speed shall not exceed 40 kilometers per hour, and the distance between vehicles shall be kept above 50 meters. Danger: Fog when driving. In addition, when encountering heavy fog, always use a wiper to brush the water vapor outside the windshield. Due to the large temperature difference between the cab and the outside, the inside of the windshield is often covered with a thin layer of water mist, which blocks the line of sight. At this time, you can use the defogging block of the air conditioner to quickly defog; Or open a slit in the window to let the air inside and outside the car circulate, which can avoid the fog from condensing on the windshield; If you want to wipe the fog off the windshield by hand, be sure to park your car at a safe place on the side of the road before wiping it. Don't wipe it while driving, it's dangerous! If you encounter foggy days in expressway or on ordinary highways, and feel that the fog is too heavy, you can stop at the roadside and turn on the fog lights, low beam lights and double jump lights. The most important thing is that after parking, everyone should get off from the right, stay away from the road as far as possible, and never sit in the car. If you park in the emergency parking area of expressway, you'd better climb over the guardrail and wait outside the subgrade to avoid being chased by some reckless drivers.
