1. Identification of accident responsibility:
 If a traffic accident is caused by the fault of one party, it shall bear full responsibility
 If a party escapes, causing changes in the scene and loss of evidence, and the traffic management department of the public security organ is unable to verify the facts of the traffic accident, the party who escapes shall bear full responsibility
 If a party intentionally destroys, forges the scene or destroys evidence, he shall bear full responsibility
 If a traffic accident occurs due to the fault of one party or two or more parties, they shall bear the primary responsibility, the equal responsibility and the secondary responsibility respectively according to the effect of their actions on the accident and the seriousness of the fault
 Each party has no fault that causes traffic accidents, and if it is a traffic accident, neither party is responsible
 If one party intentionally causes a traffic accident, the other party shall not be liable.
 2. Accident Liability Confirmation:
 The traffic control department of the public security organ shall, within ten days from the date of inspecting the scene, prepare a traffic accident identification letter for the traffic accidents that have passed the inspection.
 If a person escapes from a traffic accident, a traffic accident identification certificate shall be made within ten days after the person and vehicle who escaped from the traffic accident are found.
 If it is necessary to conduct inspection and appraisal, a traffic accident identification letter shall be made within five days after the inspection, appraisal or re inspection and appraisal results are determined.
 If the fugitive and vehicle from the traffic accident are not found, and the party concerned in the traffic accident damage compensation requests the issuance of a letter of identification of the traffic accident, the traffic management department of the public security organ may prepare a letter of identification of the traffic accident within ten days after receiving the written application of the party concerned in the traffic accident damage compensation.
 3. Nature of the accident liability certificate:
 The certificate of accident determination issued by the public security traffic management department is only one kind of civil litigation evidence. In the traffic police mediation jointly applied by the parties, the letter of determination is the natural basis. In the civil compensation action of the court, the letter of determination of accident liability is only one of the more important evidence, and is no longer the natural basis for the court to hear cases.
