After investigation, it was found that the direct cause of the accident was that Liu Mou, the owner and driver of Gui LC33xx heavy tank truck, was seriously overloaded in the process of carrying out road transport activities, driving vehicles that did not meet the technical conditions of motor vehicle operation safety, resulting in vehicle out of control in the long downhill accident-prone section. Causing a series of collisions with several vehicles waiting for release.

The specific analysis is as follows:

1. Vehicle overload transportation analysis

Gui LC33xx heavy tank truck gross mass: 31000 kg, curb weight: 17400 kg, approved load mass: 13470 kg. After testing, the actual cargo mass of the vehicle is 57,290 kg, the overload rate is 141.35%, and the vehicle is seriously overloaded.

2. The vehicle does not meet the technical conditions

of motor vehicle operation safety. After identification, the left and right tire patterns of the second, third and fourth axles of Gui LC33xx heavy tank truck are inconsistent, and the driving system is not qualified. Inconsistent tire patterns will cause uneven adhesion between left and right tires and the ground, resulting in a decline in vehicle driving stability. In addition, the vehicle is overloaded and runs on a long downhill road section, which increases the inertia of the vehicle downhill, so that the braking force provided by the vehicle brake can not meet the requirements of the overload, resulting in the extension of the braking distance, the significant reduction of the braking efficiency of the vehicle, and the vehicle can not slow down quickly and stop in time according to the driver's operation. (For details, please refer to the Judicial Appraisal Opinion [2025] Che Jian Zi No. xxxx issued by the Judicial Appraisal Center of Yunnan Academy of Transportation Sciences)

3. The traffic control department determined that

Liu's driving parts did not meet the technical standards and the load exceeded the maximum allowable total mass. Driving on the road, not driving safely and civilly in accordance with the operation norms in the long downhill section, causing the vehicle out of control, is all the fault of the accident, and Liu is found to bear all the responsibility for the accident.
