First, in foggy days, drive in strict accordance with traffic regulations. For example, if you are driving on expressway and suddenly encounter foggy weather, if the local traffic police let you off at the nearest intersection, follow the instructions and don't worry. According to the driving requirements, the visibility is 200 to 500 meters, and the low beam, width indicator and tail light are turned on, and the speed cannot exceed 80; Visibility 100-200m, except for low beam, width indicator and taillight, the speed shall not exceed 60, and the distance between vehicles shall be kept at least100m; When the visibility is between 50- 100 meters, except for turning on the above lights, the speed shall not exceed 40, and the distance between vehicles shall be kept at least 50 meters; If the visibility is less than 50 meters, in addition to turning on the above lights, it is best to turn on fog lights and danger warning lights; The above is the basic content of the subject one exam.
Second, if you encounter fog with visibility less than 50 meters, if there is service nearby, try to rest in the service area and wait until the fog clears before continuing on the road. In foggy weather, it clears up faster after the sun comes out. Even if it's cloudy, wait patiently instead of taking risks on the road.
Third, in foggy days, you can slow down at night when you can't identify the road, or even wait for the car behind you to follow other people's cars at a low speed;
Fourth, pay attention to your personal safety. When you encounter foggy weather in expressway, you can't stop at will, let alone let people get off at will and wait for the fog to disperse on the roadside, which will easily lead to continuous car accidents.
In short, the day before driving out, we should try to watch the weather forecast. If there is foggy weather, try not to go out or go out late, and try to avoid foggy days.
