Recently, there has been snowfall in many places in the north, and the incidence of traffic accidents has also risen sharply due to the impact of snowfall.
On December 10, a multi-vehicle serial rear-end collision occurred in the former Pinglaoyang section of Xinzhou, Shanxi Province of the Erguang Expressway.
According to the online report, it was snowing on the highway at that time, the road surface was slippery, many motor vehicles collided, some vehicles rolled over, serious damage, and blood stains on the vehicle airbags.
It is reported that about 40 vehicles collided one after another, resulting in one death and six injuries.
Winter travel safety accidents are frequent
Recently, a four-car rear-end collision occurred near a university in Fengtai District, Beijing, due to snowfall. 
Low temperatures and snowfall continue
Always pay attention to tire safety.
*The Meteorological Observatory will continue to issue a blue warning for cold wave at 6 o'clock on the 11th, and it is expected that in the next three days, Shaanxi, Shanxi, Hebei, Henan, Shandong, Liaoning and Xinjiang will have the risk of low temperature rain, snow freezing or blizzard disasters. From the 13th, North China, Huanghuai and other places will once again encounter a new round of heavy snowfall and cooling process. 
Rain, snow and low temperature environment have a significant impact on the safety of road surface and tire use, which is mainly reflected in the following aspects:1.Pavement adhesion decreases. In rainy and snowy weather, the road surface can become slippery or icy, resulting in a noticeable decrease in road adhesion. This will affect the handling of the vehicle, and it is easy to slip or spin, increasing the danger of driving. 2.Longer braking distances. Slippery or icy surfaces can lead to a significant increase in braking distances, as it is difficult for tires to rub against the road surface effectively in these conditions. This means that in rainy and snowy weather, the vehicle needs a longer distance to come to a complete stop, increasing the risk when braking in an emergency. 3.The tires harden. Low temperatures can cause tire rubber to harden, reducing its elasticity and adhesion. This affects the close contact of the tyres with the road, which in turn reduces handling and braking effectiveness. 
4.Tire pressure drops. In cold environments, the gas pressure inside the tire tends to drop, affecting the performance of the tire. Tyre pressure that is too low not only increases the frictional resistance between the tyre and the road, but also causes the tyre to overheat up, increasing the risk of a puncture. Check the condition of your tires regularly
Replace old and problematic tires in a timely manner.
In the face of heavy snowfall, vehicles drive like ice skating, which brings great safety hazards to driving trips.
According to statistics, the traffic accident rate in winter has increased by 50% compared with usual, and most of this is due to tire problems. As the only part of the car that is in contact with the ground, tire safety is equal to life safety. In order to cope with the impact of rain, snow and low temperature environment on driving safety, the following preventive and safety measures can be taken:1.Replace old tires in a timely manner
When the temperature is low in winter, the rubber of summer tires is more likely to harden, and the grip is greatly reduced. If there is a problem with the superimposed tires, it is more likely to cause accidentsTherefore, it is more important to replace old tires in time in winter.
Different brands of tires have different service lifespans, due to the aging of tires, it is recommended that the tire replacement cycle is 5 years, but if the tire is severely worn, it needs to be replaced even if it is only used for one year. Choosing the right tires is the key to ensuring driving safety, so what tires should be replaced in winter?Generally speaking, for safety reasons, it is best to replace winter tires with temperatures below 7 on any road surface, or to replace them with all-season tires suitable for winter use. 
The rubber formula and texture design of winter tires are more suitable for low temperatures and ice and snow roads, which can provide better grip and stability, so as to solve the problem of winter car skidding. Therefore, it is strongly recommended that all car owners, especially those in the north, replace the problem tires in time, and replace the winter tires or all-season tires if conditions are possible to ensure driving safety. In addition, in extreme snow or icy conditions, it is recommended to use snow chains to provide additional traction and improve the stability of the vehicle in adverse conditions. 2.Maintain proper tire pressureDropping temperatures in winter can cause a drop in gas pressure in your tires, so check and maintain the correct tire pressure regularly to ensure that you can still maintain good performance in low temperatures. But be careful not to over-inflate, as over-inflation can lead to excessive wear on the tire** section, which can reduce grip. 
3.Check the condition of your tires regularlyRegularly check the overall condition of the tire, including whether there are any breakages, cracks or foreign objects, especially the wear of the tire, the depth of the grain of the tire in winter is crucial for grip and drainage performance, if the texture has been worn to the specified limit, the tire should be replaced in time to ensure the safety of driving. Write at the end
Xiaobang also reminds all car owners that in rainy and snowy weather or low temperature environments, while ensuring the safety of tires, they should also adjust their driving behavior, slow down their driving speed, and maintain a safe distance to avoid rear-end accidents. The temperature drops, the road is slippery on snowy days, I wish all car owners a smooth journey and a safe trip!
