What regulations should be observed when driving on the expressway under low visibility meteorological conditions?
(1) When the visibility is less than 2 meters, turn on the fog lights, low beam lights, position lights and front and rear position lights, and the speed should not exceed 6 kilometers per hour, and keep 1 meters with the vehicle in the same lane.
(2) When the visibility is less than 1 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 4 kilometers per hour, and keep a distance of more than 5 meters from the vehicle in front of the same lane;
(3) When the visibility is less than 5m, turn on the fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and the speed shall not exceed 2km per hour, and leave the expressway from the nearest exit as soon as possible. In case of the circumstances specified in the preceding paragraph, the expressway management department shall release the prompt information such as speed limit and distance keeping through the display screen.
it should be noted that when driving a motor vehicle on an expressway, the visibility should be below 2m and the speed should not exceed 6km/h in case of low visibility meteorological conditions, and the distance between the vehicle and the vehicle in front of the same lane should be at least 1m to ensure safety. In different grades of rainfall, the damage coefficient of light rain is very high, even exceeding the damage degree of heavy rain. The reason is that light rain has little influence on the vision when driving, and drivers are easy to relax their vigilance. However, light rain can wet the dust on the road and become a good lubricant. When an emergency occurs, the braking distance of emergency braking increases, causing traffic accidents, which has become the main mode of traffic accidents on some roads in rainy days. Compared with precipitation, snowfall has a more serious impact on traffic safety. In case of emergency braking, rollover, rear-end collision and serial collision are easy to occur. In addition, in the snowy weather, auto start is difficult, especially on the uphill section, and it is easy to slide backwards and collide with the rear car. In addition, snowfall will cover up the original potholes or obstacles on the road surface, which will bring great safety hazards to driving safety. In the case of freezing, it is difficult for vehicles to drive, and emergency braking is prone to locking. In addition, freezing will seriously affect the quality of pavement and easily lead to problems such as pavement cracking and bagging. When it is frozen and melted, it will break through the roadbed and overflow along the road, which will pose a serious threat to traffic safety; When the freezing is serious, the roadbed will sink, even lead to landslides and other problems, which will affect the driving safety.
