Snow-triggered multi-car pile-up left dozens injured on an expressway in southwest China.

The dramatic video was filmed in Tongren City in Guizhou Province on January 22.

According to an eyewitness driver, the accident happened on a downhill stretch under an overpass, where the road was covered in snow. The chain-reaction crash began when several vehicles collided, and following cars were unable to stop in time, leading to a pile-up.

As car doors jammed, passengers and drivers were forced to escape through shattered windshields and windows.

Hospital staff attending to the injured reported multiple casualties were brought in for treatment, primarily in the orthopedics department.

Fortunately, none of the injuries were life-threatening.

By the evening of January 23, the Tongren Highway Patrol responded, stating that the accident site had been cleared. The expressway section where the incident occurred was temporarily controlled due to weather conditions, indicating a proactive measure to prevent further accidents.

一名过路司机介绍，事故发生路段是高架桥下坡处，事发时路面有积雪，前面有几辆车出事故了，后面的车没刹住就撞上去了。因为车门打不开了，有司乘人员从破裂的挡风玻璃或者窗户逃生。
接诊医院一名工作人员称，有多名伤者送医，主要在骨科等科室治疗，均无生命危险。
23日19时许，铜仁高速交警回应称，事故路段已处置完毕，事发高速路段因天气原因已经采取临时交通管制措施。
