How to drive safely in foggy weather?

The foggy weather has brought great safety hazards to drivers, which can easily lead to accidents if they are not careful. Many rear-end collisions on expressways occur in foggy weather, resulting in great losses in personnel and economy and posing a serious threat to the safety of expressway driving. In order to drive safely in foggy weather, here are some precautions for driving in foggy weather:

First, use car lights reasonably

The correct use of car lights is an important factor to ensure driving safety in foggy weather. When driving in foggy weather, the driver should turn on all the front and rear fog lights, and if the fog is very heavy, he can also turn on the double flashing lights. The main function of turning on fog lights and double flashing lights is to let drivers of other vehicles observe you better and avoid rear-end collision or scraping accidents. In addition, check whether the wiper is in good condition before going out. When the fog falls on the windshield during driving, make sure that the wiper can scrape off the water vapor smoothly to ensure a good line of sight.

Second, hearing from all directions is very important. Hearing is equally important to the driver when driving on the expressway. Once you hear the sound of a car colliding in front, you should stop at the side of the road quickly and turn on all the lights while ensuring safety. People in the car need to climb over the guardrail and wait on the side of the road, and walk along the outside of the road to set up a warning sign 15 meters behind the car, and then leave the road quickly after completion. Once there is a rear-end collision on the foggy highway, most of them are serial rear-end collisions. At this time, people should leave the road quickly to ensure their own safety.

Third, pull over at the right time

In case of sudden arrival of dense fog, it is too late to enter the nearest service area, you should park your car on the expressway emergency stop as soon as possible, and turn on the fog lights, width indicators and taillights at the same time. In addition, warning signs should be set 15 meters away from the direction of incoming vehicles. After parking, get off on the right, stay as far away from the road as possible, never sit in the car, and avoid the guardrail to avoid being hit by passing cars. When the line of sight is restored to a certain extent, leave the emergency stop as soon as possible.

Fourth, stay in the fog

Don't drive until the line of sight is completely restored. In the foggy weather, drivers must wait patiently and don't rush into the foggy area in order to seize time. Because the fog along the expressway is often thick and light at the beginning of the fog, it is difficult to control the speed and traffic accidents are more likely to occur, so we can't take it lightly.

Fifth, pay attention to speed limit driving

Even in the light fog area, the driving speed should be appropriately reduced and the driving distance should be appropriately increased. When the visibility is 2 meters to 5 meters, the anti-glare low beam lamp, width indicator lamp and tail lamp must be turned on, the speed shall not exceed 8 kilometers per hour, and the distance between vehicles shall be kept above 15 meters. When the visibility is between 1 meters and 2 meters, the fog lights, anti-glare low beam lights, width indicator lights and tail lights must be turned on, the speed should not exceed 6 kilometers per hour, and the distance between vehicles should be kept above 1 meters. When the visibility is between 5 meters and 1 meters, except turning on the above lights, the speed should not exceed 4 kilometers per hour, and the distance between cars should be kept above 5 meters. When the visibility is below 5 meters, it is extremely dense fog, and the public security organs can take traffic management measures to close the expressway in part or in whole according to regulations. At this time, the driver of the vehicle that has entered the expressway must turn on the fog lights, anti-glare low beam lights, width lights and tail lights according to the regulations, and leave the foggy area under the principle of ensuring safety, and the speed should not exceed 2 kilometers per hour. You can also find the nearest service area to temporarily avoid and wait until the fog clears.

Sixth, defogging skills for front windshield

When driving in foggy days, it is easy to fog on the front windshield, so don't drive while wiping the fog. When encountering fog on the front windshield, turn on the air conditioner or slightly open the window, so as to eliminate or avoid fog on the glass.
