What problems should novices pay attention to when driving in foggy winter?

What should I pay attention to when driving in foggy and snowy days? The main points are as follows:

The traffic police reminded that keeping the distance between cars and slowing down the speed is the key.

Since winter, fog has covered the road from time to time. If it snows again, it will be a test for drivers to drive safely, especially novices.

In winter, the temperature difference between day and night is large. In case of rain and snow, the icy road surface will directly affect the grip of tires, and the car is easy to slip. Recently, the reporter interviewed Chen (hereinafter referred to as Ji and Chen), a policeman of the high-speed traffic police detachment of Jinhua Public Security Bureau, about the driver's driving safety in winter.

Reporter: What's the difference between winter paving and summer paving?

Chen: There are generally only two kinds of roads in summer, one is wet and the other is dry. Drivers can generally adapt to these two kinds of weather. In winter, the road surface is much more complicated, and fog, rain, snow and freezing weather are often encountered. Affected by this weather, the road surface will be dry, wet, unfrozen and frozen. Driving in winter, if you don't have a strong sense of safety, is prone to traffic accidents, especially on the highway.

Reporter: What should I pay attention to when driving on the highway in foggy days?

Chen: High-speed traffic police will take timely measures such as road closure, diversion and guidance according to the foggy situation to ensure the driver's driving safety. If the expressway is not closed after heavy fog, you should pay attention to the road surface changes when entering or driving on the expressway. When driving, you should turn on the double jump lights and fog lights, slow down the speed and keep a distance from the car in front. When braking is needed, it is not easy to brake suddenly, and continuous braking should be the main method. For safety reasons, it can also give a warning to the vehicles behind. When you see an exit sign ahead, if you don't get off at this exit, vehicles should drive on the left, and pay attention to whether there are cars queuing up to get off the expressway. If you get off at this intersection, you should drive in the right lane instead of the overtaking lane. If there is a car in line in front, keep a distance from the car in front to avoid rear-end collision. After getting on the expressway, if the traffic police take road closure measures, the driver should obey the traffic police's command and get off the expressway nearby under the guidance or command of the traffic police.

Reporter: What should I pay attention to when driving in snowy days?

Chen: When driving, I found that the windshield was covered with ice and snow, so I couldn't wash it with hot water. I should turn on the hot air conditioner of the vehicle and blow the glass to let the snow melt slowly.

On snowy days, the sight is not good and the road surface is slippery. When driving, keep the distance between cars and slow down. When turning or encountering an emergency, it is not advisable to turn sharply to avoid slipping. In addition, it is not advisable to overtake and overspeed blindly. Snowflakes falling in front of your eyes are easy to cause visual fatigue. In this case, you should go to the nearby service area to have a rest.

Reporter: Is there a difference between driving when the road is frozen and driving in snowy days?

Chen: It's very different. Driving in winter, the biggest fear is that the road will freeze after snow. A traffic accident that killed two people on Jinliwen Expressway from June 5 to/KLOC-0 to October 7, 2003 was caused by the icing on the bridge deck.

The road surface is easy to freeze after snow. Even if it doesn't freeze during the day, it will freeze at night, and it will freeze after the first half of the night. Some drivers think that all roads are not frozen when they see that asphalt roads or cement roads are not frozen, which is wrong. Affected by geothermal energy, the ice and snow on normal pavement melt faster than that on bridge deck. If you encounter an icy bridge deck on the expressway, it will be a bit late to take measures.

Reporter: It is easy to have steam in the car in winter. In order to have a good view, can you wipe the glass with a towel while driving?

Chen: This practice is absolutely not allowed, especially at high speed. The specific method is to turn on the warm air conditioner, adjust the air outlet to the glass level and blow air into the air conditioner.

Reporter: Why is it easy to get sleepy when driving at night in winter?

Chen: When driving in winter, most of the windows are closed and the air conditioner is on. Driving itself is very tiring, and coupled with the warm air of air conditioning, the sleepiness is even heavier. In this case, you should get off in time and let the cold wind blow for a while.
