What are the main factors that affect safe driving in rainy days?

The main factors affecting safe driving in rainy days are: slippery road surface, affecting driving sight, less wheel adhesion and water accumulation on the road surface.

1, road surface slippery: the road surface is wet by rain in rainy days, and the rain has a certain lubricating effect between the road surface and the tires, which leads to the situation that the vehicle is easy to slip. So when driving in rainy days, you must slow down and don't use the brakes casually.

2. Influence of driving sight: If the rainfall is heavy, it will reduce the visibility of the driver's sight on cloudy days, so turn on the lights in time to increase the visibility of the vehicle. At the same time, drive carefully on the road and turn on the wiper. Fog lights and low beam lights should also be used when the weather is dim.

3. The adhesion of the wheels becomes smaller: due to the rain, with the increase of the vehicle speed, the adhesion of the wheels becomes smaller rapidly, and it is generally easy for the wheels to slip in rainy days. At this time, high-speed driving should be avoided, but the speed should be controlled reasonably.

4. Road water accumulation: There is also the fact that it is easy for rain to cause potholes on the road surface, leading to the formation of road ditches, which makes it difficult for drivers to judge the quality of road conditions or lead to drivers' misjudgment. At this time, we should be careful to avoid it.

Precautions for safe driving in rainy days

1, keep a safe distance.

Because the line of sight is poor in rainy days, we should keep a greater distance than usual. If the water sweeping ability of the wiper decreases, it will be more difficult to observe the road conditions when driving in rainy days, especially when driving at high speed, the wiper blade floats up and the water sweeping ability is even worse. In addition, driving in rainy night, the raindrops that are not scraped clean will produce all kinds of reflected light under the light, blurring the front sight. Therefore, it is best to wax the front windshield, so that a layer of wax film can be formed on the surface of the glass, and the wiper will sweep the water thoroughly to protect the glass.

2. Don't restart after the flameout.

In case of rainstorm or heavy rainstorm, some sections will be seriously flooded in a short time. If you have to wade, you should use low gear to pass at a constant speed. If the vehicle stops running, don't try to start it again. Blind starting may lead to engine scrapping. After the vehicle is turned off, you should contact the specialized shop in time. After the maintenance personnel check the vehicle on site and make sure there is no problem, they can start it again.
