Speed limit of expressway in foggy weather

The speed limit of expressway in foggy days is to ensure that vehicles can drive safely and orderly in low visibility.

First, the importance of highway speed in foggy days

The visibility is low in foggy days, and the driver's sight is seriously affected, and the speed of judging and responding to road conditions will decrease. At this time, if the speed of the vehicle is too high, once an emergency occurs, the driver may not be able to respond in time, leading to traffic accidents. Therefore, it is very important to control the speed of expressway in foggy days reasonably.

Second, the specific provisions of the speed of the foggy highway

According to the "Regulations on the Implementation of the Road Traffic Safety Law of the People's Republic of China", when a motor vehicle is driving on an expressway, it shall comply with the following provisions in case of low visibility meteorological conditions such as fog, rain, snow, dust and hail:

1. When the visibility is less than 200m, turn on the fog lights, low beam lights, position lights and front and rear position lights, and the speed shall not exceed 60km per hour, and keep a distance of100m or more from the vehicle in front of the same lane;

2. When the visibility is less than 100 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and the speed shall not exceed 40 kilometers per hour, and keep a distance of more than 50 meters from the vehicle in front of the same lane;

3. When the visibility is less than 50 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and danger warning flashlights, and the speed shall not exceed 20 kilometers per hour, and leave the expressway from the nearest exit as soon as possible.

These regulations are designed to ensure that drivers can maintain an appropriate speed and distance in foggy days so as to have enough time and space to respond in an emergency.

Three. Matters needing attention in driving in foggy weather

In addition to observing the above-mentioned speed regulations, you should also pay attention to the following matters when driving in foggy days:

1. Know the road conditions and weather information in advance and arrange the travel time and route reasonably;

2. Keep the vehicle in good condition and check whether the key components such as lights and brakes work normally;

3. Stay focused while driving and always pay attention to changes in road conditions;

In an emergency, keep calm and take correct measures.

To sum up:

The speed limit of expressway in foggy days is to ensure that vehicles can drive safely and orderly in low visibility. According to the relevant provisions of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, drivers should reasonably control the speed and distance of vehicles according to different visibility conditions when driving on foggy highways, and observe other relevant precautions. Only by strictly observing these regulations and precautions can we effectively reduce the occurrence of highway traffic accidents in foggy days and ensure traffic safety.
