What should I do if the responsibility for traffic accidents cannot be determined?

Judging from judicial practice, unless there are live videos, witness testimony or other evidence clues, it is generally difficult to identify the subjective and intentional "secondary impact" phenomenon from the scene alone. Brake marks and evidence of whether the perpetrator is ready for the collision can generally be pleaded as avoidable subjective negligence due to negligence or credulity, so such evidence cannot be used as direct evidence to directly prove the crime. However, in the cause of the secondary collision phenomenon of traffic accidents, "subjective intention" and "subjective negligence" are logically contradictory, that is, they cannot be true or false, and there must be one truth and one falsehood. That is to say, when there is a second collision in a traffic accident, if the subjective intention of the other party cannot be proved, it means that the other party has at least subjective fault. At the same time, the secondary collision in traffic accidents is caused by traffic violations or accidents. If the traffic accident itself meets the conditions of the traffic accident crime, even if there is negligence leading to a second collision, it will be absorbed by the traffic accident crime, and criminal and civil responsibilities will be investigated.
