In China, according to the provisions of the "Road Traffic Safety Law", after a traffic accident, regardless of whether anyone is injured or not, the parties concerned should immediately stop, protect the scene, and promptly call the police (if it causes casualties or property damage). The following are specific suggestions： 1. **Legal obligations**： -**No one was injured but there was property damage**: If the accident caused damage to the vehicle, public facilities or other property, you still need to call the police and wait for the traffic police to deal with it. Failure to report to the police may be considered an escape, especially when third-party property is involved (such as guardrails, street lights, etc.). -**Minor accidents can be private**: If there is only a minor scratch and the two parties have no dispute over the responsibility, you can take pictures and collect evidence, record the other party's information, and go to the traffic police department to issue a "Certificate of Responsibility for Traffic Accidents" or process it online through traffic control 12123App. However, it is necessary to ensure that evidence is left to avoid subsequent disputes. 2. **Insurance claims**： -Insurance companies usually require a "Certificate of Liability" issued by the traffic police as the basis for claims. Failure to report the alarm may lead to difficulties in making claims, especially when the division of responsibilities is unclear. 3. **Operation recommendations**： -**Protect the scene**: Turn on the double flashing lights and place warning signs to avoid secondary accidents. -**Keep evidence**: Take on-site photos (including vehicle location, damaged parts, road markings, etc.), record the opponent's license plate, driver's license and contact information. -**Negotiation and processing**: If both parties agree to go private, it is recommended to sign a written agreement, clarify the liability and compensation method, and contact the insurance company as soon as possible. 4. **Exceptions**： -If the accident occurs in a closed private place (such as a parking lot) and only involves the vehicles of both parties, it can be resolved through negotiation. However, if there is a dispute over responsibility, it is still recommended to call the police. **Summary**: Even if no one is injured, calling the police is a safer choice, especially when it involves property damage or liability disputes. Be cautious in private matters, keep evidence and ensure written confirmation by both parties to avoid subsequent disputes. It is recommended to check the specific regulations of the local traffic police department (such as the “quick settlement and quick compensation” policy) in order to deal with it efficiently.
