Even if no one is injured in the accident, it is recommended to call the police for the following reasons: - **Determination of liability and compensation required**: After calling the police, the traffic police will go to the scene for investigation and issue a traffic accident liability determination letter based on the accident situation. This is an important basis for determining the party responsible for the accident and is crucial for subsequent insurance claims. Without a liability determination letter, the insurance company may not be able to accurately make claims. - **Protecting legal rights and interests**: After the responsibility is clearly determined, the responsibilities of all parties can be clearly divided to avoid disputes caused by unclear responsibilities in the future. For example, if the police are not called in time to fix the evidence, the other party may regret and refuse to admit it, or have different opinions on the responsibility for the accident, resulting in damage to their own legal rights and interests. - **Standardized accident handling**: The intervention of the police can ensure that the accident is handled in accordance with legal procedures and ensure the fairness and legality of the handling process. - **Retain records**: The alarm record is an important proof of the occurrence of the accident. When necessary, it can be used as evidence to prepare for other possible situations, such as insurance claims disputes, vehicle resale, etc.
