Matters needing attention in running high-speed in snowy days

Precautions for running high-speed in snow, it is very difficult to run high-speed in snow. On the one hand, there is a speed limit on high speed, which is too slow. On the other hand, running fast is not safe. There are many things to pay attention to on the expressway. Let's take a look at the precautions for running on the highway in snowy days.

Precautions for running high-speed in snowy days 1 First thing: slow down.

The speed limit of the expressway is 120, but if it really snows 120, I can only say that it is fatal. Generally speaking, before it snows heavily, you will be prompted to speed limit 60 on the expressway, which is relatively easy to control the car. Not to mention the four-wheel drive, simple two-wheel drive is not easy to be dangerous. If there are special circumstances, it is relatively simple for the driver to control the good car. At this time, I personally suggest that you don't park in emergency lanes and other places casually. It is best to follow the team. Besides, we should make rational use of lighting.

The second thing: wait a little longer in the service area.

Why let everyone wait in the service area for a while? Whether it is a joint venture car or a domestic car, it is actually very dangerous to drive in this weather, because after about half an hour, the snow on the road will not melt, and the road will become slippery, and your car will easily slip when driving at this time. At present, the emergency mechanism of domestic expressways is still very comprehensive. Basically, soon after it snows, trucks will start to sprinkle salt and other snow removal operations. When you drive on the expressway in the service area for a while, you may find that the road surface in Mao Mao has just rained. Although it is slippery, it is no problem to drive 8 or 90, but I suggest you speed limit.

The third thing: don't overtake casually.

Some friends have nice cars. Today, they met a traffic accident. At that time, a Land Rover Range Rover copied a Volkswagen Jetta. The road is slippery on snowy days, and the road surface is basically drifting when I drive there. But Land Rover overtook it by two lanes, and then maybe Volkswagen Jetta was unhappy or excited, and rushed directly in front of Land Rover. I don't need to say anything more. I passed two cars at a speed of more than 20.

The fourth thing: fill the cup with water.

After reading the first three articles, many people may be confused when they see here. I-do you know what you're writing? To tell the truth, old drivers understand the importance of glass water, especially in this weather. The first situation is that it snows all the time, and the snow on the car glass can be quickly removed with glass water. In the second case, once the road surface melts, the mud spots brought by the front car will instantly blur your front window. Do you think it is good not to add glass water? Therefore, many times, car glass water is a life-saving existence. In addition, I would like to remind you that it is winter, and we should use glass water in winter instead of glass water in summer. It is easy to freeze and crack in minutes.

Precautions for running high-speed in snowy days 2 How to drive in snowy days

1, pay attention to turn on the light. Generally, visibility is low in snowy days, so attention should be paid to the correct use of lights. First of all, turn on the fog lights and low beam lights to help the driver look forward and let the driver see the situation ahead more clearly. The second is to turn on the position lights and the front and rear position lights to indicate the existence of their own vehicles, so that the vehicles driving back and forth can see their specific positions and traffic conditions, so that they can take corresponding measures.

2. Keep driving at a low speed. According to experts, the adhesion coefficient of ice and snow pavement is 0. 1 or 0.2, which is far from the adhesion coefficient of dry oil pavement of 0.7 or 0.8. If you drive at the same speed of 90 kilometers per hour, the braking distance of dry oil pavement is only more than 30 meters, while the braking distance of ice and snow pavement needs 150 meters. Due to the low adhesion coefficient, the traffic safety law requires cars to slow down when driving on ice and snow roads. The visibility is low in snowy days, and the distance that the eyes can see is close, so the speed of the car must be proportional to the sight distance. When the visibility is less than 200 meters, the speed should be less than 60 kilometers per hour; Visibility less than 100 meters, speed less than 40 kilometers, visibility less than 50 meters, speed less than 20 kilometers, get off the expressway.

3. Keep a safe distance from the vehicle in front. It is very important to keep a safe distance when driving on snowy highways. Because the snowy road is slippery, its braking distance is five to six times longer than that of dry asphalt road. It is not advisable to take sudden braking in snowy days to prevent vehicles from slipping. Visibility is also low on snowy days. According to the regulations, visibility less than 200 meters must keep a distance of 100 meters or more from the vehicle in front; Visibility is less than 100 meters, and it is necessary to keep a distance of more than 50 meters from the vehicle in front; Visibility is less than 50 meters, so you should leave from the expressway. The safety distance between the expressway and the vehicle in front in snowy days should consider both visibility and road slip.

4. Keep enough temperature in the good car, and the wiper is effective. The main method of ice, if the rain and snow on the front windshield can't be scraped off, or the frost lives, the driver can't see the road ahead clearly and the vehicle can't move forward.

5. Before getting on the expressway, you should try to understand the recent weather and traffic conditions along the way, so as to adjust your itinerary in time. After getting on the expressway, you should also pay attention to the tips of the pavement variable information board and drive according to the reminding information of the pavement.

6. In case of ice skidding, don't brake suddenly, don't slam the direction, downshift and slow down, and brake to stop the car slowly.

Precautions for running high-speed in snowy days 3 1, and starting in snowy days is also a problem that cannot be ignored.

For automatic cars, just turn on the snow mode. For manual cars, it is recommended to start in second gear. Its principle is as high-grade and low-speed as the snow mode, which can alleviate the starting slip on slippery roads such as ice and help you control the vehicle more easily in the snow. Of course, the snow mode is not that simple, but also includes the opening of the throttle and the response of the gearbox.

It is also important to keep the distance when driving on the expressway in winter.

In particular, the resistance of ice and snow pavement is very small, so when turning or going downhill on ice and snow pavement, the speed must be controlled at a low speed that can be stopped at any time; When it is necessary to accelerate or decelerate, increase or decrease the throttle slowly to prevent slipping. According to the terrain, speed and load, the driver should keep a normal driving distance of more than 2 times from the vehicle in front.

Although many colored glasses such as sunglasses will hinder driving, snowy days are an exception.

Walking on the highway in snowy days often leads to dazzling situations. Wearing appropriate colored glasses and paying attention to proper rest can prevent glare and eye fatigue and help to look forward better. Then, keep a good attitude and calmly deal with unexpected situations in order to reach the destination safely.

4. Drive at high speed in snowy days to avoid sudden braking.

One thing that people sometimes tend to overlook is the sudden braking, which is quite dangerous. Sudden braking in snowy days, especially at high speed, can easily lead to sideslip or rear-end collision. Even if the vehicle has ABS or ESP, the risk factor is still high. Therefore, it is safer to brake slowly, that is, brake gently and click a few times after lifting your feet.
