A truck driver stopped an out-of-control tractor doing doughnuts on a road in eastern China.

CCTV footage filmed in the city of Yantai in Shandong Province on January 30 shows a tractor suddenly throwing the rider out and spinning around repeatedly in the middle of a road with an elderly woman on it.

A truck driver named Zhang Guoyong spotted the incident when driving past the scene so he stopped his vehicle and ran to help the tractor rider.

After Zhang caught the tractor's handle, the vehicle dragged him down to the ground. But he finally controlled the tractor successfully by using his previous driving experience.

According to reports, the tractor suddenly lost control as the rider accelerated too much when it was about to turn around.

1月30日上午，山东烟台乳山下初镇一路口。一辆手扶拖拉机在路中央失控后原地打转，一名男子与同事恰巧路过，该男子见此情景立刻拔足狂奔，冲上前去控车，被拖拉机拽倒在地后，男子左膝盖受伤，但他忍着疼痛，干脆利落地控制住了手扶拖拉机。
经了解，危急时刻出手相助的热心人，是山东汇通能源利用集团威海分公司危化品车辆驾驶员张国勇。当天，他正和同事驾车为用户送气。
“在远处就看到了，以为出交通事故了，来到跟前，才看到是一辆拖拉机失控了。”张国勇说，拖拉机在路中央一直转圈，一名大爷正跟在拖拉机后面转圈，车斗里还有一名大姨，吓得蜷缩在车斗里。
救人重要！危急时刻，张国勇没有丝毫犹豫，他戴好手套，仔细观察手扶拖拉机的车况，瞅准时机一个箭步冲了上去，握住手扶拖拉机的车把。尽管巨大的惯性把他带得跪倒在地，但依靠此前驾驶类似手扶拖拉机的经验，他最终成功地将失控拖拉机控制住了。
据了解到，驾驶拖拉机的大爷当时正拉着老伴去镇上办事，到事发地段时正准备转弯，没想到油门加得过猛导致拖拉机失控，将他从驾驶台甩了出来，幸好张国勇及时相助，才没有造成安全事故。
