A teenage boy on a scooter narrowly escaped being run over by a heavy semi-trailer truck that ran a red light in northwestern China.

Terrifying CCTV footage filmed in Shizuishan City in Ningxia Hui Autonomous Region on July 4, shows a truck running a red light, narrowly missing a 12-year-old boy on a scooter.

Ma, the driver of the semi-trailer, was travelling westward along Provincial Highway 302. Despite the red light, Ma made no attempt to slow down and drove straight through the intersection. At the same time, the teenager, Su, was riding a scooter, attempting to cross the zebra crossing from the right side of the intersection.

Suddenly confronted with the looming truck, Su tried to brake and swerve to avoid it. However, the high speed and slippery road caused him to lose control and crash to the ground.

The scooter slid under the truck and was crushed beyond recognition. Miraculously, Su managed to roll out of the way just in time, narrowly escaping being run over by the truck's wheels.

After examining the scene, reviewing surveillance footage, and questioning those involved, the local traffic police concluded that Ma bore the primary responsibility for the accident due to running the red light.

However, Su was also found to be partially at fault for riding a scooter without being of legal age and failing to observe traffic regulations.

近日，宁夏石嘴山市发生了一起令人揪心的交通事故，一名年仅12岁的男孩在骑行电动自行车时，险些被一辆闯红灯的重型仓栅式半挂车碾压。
监控画面显示，7月4日下午，马某驾驶一辆重型仓栅式半挂车沿302省道由东向西行驶至该路口时，无视红灯的警示，未采取任何减速措施，直接闯红灯通过。与此同时，12岁的小苏骑着电动自行车，正准备从路口右侧直行过斑马线。面对突如其来的大货车，小苏紧急刹车并试图避让，但由于车速较快且路面湿滑，他连人带车摔倒在地。更危险的是，他的电动自行车在惯性作用下滑入了大货车底部，瞬间被碾压变形。幸运的是，小苏本人在关键时刻迅速翻滚到一旁，避免了被车轮直接碾压的悲剧发生。
事故发生后，当地交警部门迅速介入调查。经过现场勘查、调取监控视频并询问当事人后，交警部门认定大货车司机马某因闯红灯通行负事故主要责任；而12岁的小苏因未满法定年龄驾驶电动自行车上路且未遵守交通规则负次要责任。
