What level is the fog red warning?

Fog red warning signal is a Class I warning, which means it is particularly serious. Fog with visibility less than 50 meters may appear within 2 hours, or fog with visibility less than 50 meters has appeared and will continue.

Fog weather causes low visibility near the ground, which affects people's travel, production and work, and is particularly easy to induce vicious traffic accidents. To this end, meteorological, public security, transportation, construction and other departments should cooperate closely to implement the meteorological information release system, and report it through TV, radio, internet, newspapers and other media and mobile phones by means of short messages and electronic display screens.

Timely and accurate release of fog weather warning information and traffic control measures, and effectively enhance the ability to deal with emergencies caused by fog. It is clearly required that all departments and enterprises conscientiously implement the 24-hour duty system and the leadership shift system. Establish a scientific and effective fog damage prevention and control mechanism, and improve and implement a scientific special plan for fog damage prevention and control.

Grasp the foggy weather forecast information and the time, road section and scope of fog in time. Strengthen the management of transportation enterprises and water ferries. Ensure that after the accident, the emergency plan can be quickly started, and the linkage measures for traffic accident rescue in foggy days can be implemented to achieve rapid rescue, rapid exploration and rapid removal of the scene, so as to minimize losses.

Matters needing attention when traveling in foggy days:

1, use the lamp correctly

When driving in foggy days, you should observe the regulations on the use of lights: turn on fog lights, tail lights, width lights and low beam lights, improve visibility, see clearly the dynamics of vehicles and pedestrians, and avoid rear-end collision or scraping accidents. But don't use high beam. The high beam light is high, and it is easy to penetrate into the eyes of the driver driving in the opposite direction after being refracted by fog, which blurs his line of sight and causes accidents.

2. honk the horn often

In foggy days, the line of sight is not good. Frequently honking the horn can warn pedestrians and vehicles, and at the same time indicate the position of their vehicles to avoid collision accidents due to low visibility.

Step 3 drive at a low speed

In foggy days, even in light foggy areas, the driving speed should be appropriately reduced and the driving distance should be appropriately increased. When the visibility is between 200m and 500m, the vehicle speed shall not exceed 80km per hour, and the distance between vehicles shall be kept above150m. When the visibility is between 100m and 200m, the vehicle speed shall not exceed 60km/h, and the distance between vehicles shall be kept above100m.

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. When the visibility is less than 30 meters, the speed should be controlled below 20 kilometers per hour; Generally, when the sight distance is about 10 meter, the speed should be controlled below 5 kilometers per hour.

When the visibility is extremely low due to heavy fog, it is recommended that you drive to the roadside safety zone or parking lot, and then move on after the fog clears or the visibility improves. When the temperature is low and the humidity is high, the pavement is easy to form thin frost, so it is necessary to avoid emergency braking.
