am not a lawyer, but I can provide you with some general information. Specific requirements may vary depending on the regulations of the country or region. In many places, even if no one is injured in the accident, if there is vehicle, property damage or other legal liability, it is usually recommended or required to call the police. The reasons include: 1. Accident investigation and liability determination: The accident report issued by the police can help clarify the responsibility for the accident and serve as the basis for subsequent handling of insurance claims or legal disputes. 2. Legal regulations: Traffic regulations in many regions require that traffic accidents (even if no one is injured) must be reported to the police or to the relevant departments within a certain time limit, otherwise you may face penalties or affect insurance compensation. 3. Protection of the rights and interests of both parties: After calling the police, the facts recorded by the police can help protect the legal rights and interests of both parties in the process of handling the accident and avoid disputes in the future. Therefore, if you encounter an accident, it is not only to ensure that the accident is handled in accordance with regulations, but also to help with claims or dispute resolution that may arise later. It is recommended that you: • Understand the local legal requirements for traffic accidents. You can consult the local public security department or check relevant regulations. • If you are not sure whether you need to call the police, call the local non-emergency police phone number for consultation or legal advice in a timely manner. Most importantly, pay attention to collecting evidence (such as taking photos, recording the accident scene and information of both parties) when handling the scene, so that you can provide a detailed record of the accident when necessary.
