The cause of this traffic accident was also determined to be the unsafe weld connecting the truck to the concrete pump, which was the culprit leading to the accident.
While traveling, the hook connected to the truck's pump broke, causing the pump to fall out in the middle of the road. The unexpected incident caused the driver of the 16-seat passenger car to swerve to avoid it, causing a head-on collision with another passenger car, causing an accident. It is known that the 16-seat bus carried 12 people, the 29-seat bus carried 20 people, and the casualties were all on the 16-seat bus.
