What are the precautions for driving in foggy weather?

When driving in foggy weather, pay attention to the following points: 1. Use lights correctly. When driving in foggy weather, visibility is low. Fog lights and position lights must be turned on, and the use of high beams is prohibited. Because the high beam shines upward, the light emitted is diffusely reflected by the fog, forming a white field in front of the car, but it affects driving. Fog lights have high light transmittance, which is better than tail lights. When the fog lights are turned on, other car owners can clearly identify the vehicle. 2. Control the vehicle speed. There are legally stipulated speed limits for driving in foggy weather, as follows: when the visibility is less than 500 meters and greater than 200 meters, the speed shall not exceed 80 kilometers per hour; when the visibility is less than 200 meters than 100 meters, the speed shall not exceed 60 kilometers per hour; when the visibility is less than 100 meters but greater than 50 meters When visibility is within 30m, the speed should be controlled below 20km; when visibility is around 10m, the speed should be controlled below 5km. 3. Keep a safe distance from the vehicle in front, do not follow too closely, and do not overtake casually. This is mainly to prevent rear-end collisions due to insufficient reaction time when an accident occurs (the vehicle in front of the vehicle applies emergency braking). 4. Frequently sound your car horn to indicate your location.
