In China, whether you need to call the police after a traffic accident does not entirely depend on whether someone is injured, but on the specific circumstances and legal requirements to judge. The following are the key factors to consider： ### 1. **The severity of the accident** -**Minor uncontested minor accidents**: If the accident only causes minor property damage (such as minor scratches), the two parties have no dispute over the liability, and meet the local "Quick compensation" conditions (such as the vehicle can move, complete documents, etc.), you can ** without calling the police**. However, it is necessary to take pictures and collect evidence as required, fill in the "Traffic Accident Self-negotiation Agreement", and evacuate the scene to the insurance company or the traffic police department for processing as soon as possible. -**Large losses or disputes**: If the vehicle is severely damaged, public facilities (such as guardrails and street lights) are involved in damage, or the two parties have differences in liability, **You must call the police** (122 or 110), and the traffic police will issue a certificate of liability. ### 2. **Situations where the law expressly stipulates that the police must be called** -**Article 70 of the "Road Traffic Safety Law"**Stipulates: As long as any of the following circumstances occur in a traffic accident, the police must be called： -Cause casualties (even if there is no injury on the surface, internal injuries may occur afterwards)； -The driver is suspected of drunk driving, drug driving, driving without a license and other illegal acts； -The vehicle is unlicensed, uninsured or forged documents； -One party escaped. ### 3. **Post-mortem risk aversion** -Even if no one was injured at the time, the other party may claim for potential injuries (such as soft tissue injuries) afterwards. Alarm records and the determination of the responsibility of the traffic police are important evidence to avoid disputes. -When a third-party loss (such as damage to shop items) is involved, the police can clarify the responsibility. ### Recommended operation process： 1. **Stop immediately to protect the scene**, turn on the double flash, and place a warning sign. 2. **Preliminary judgment**: If there are no casualties, small losses and clear responsibilities, it can be handled according to the expedited process. 3. **If you have any questions or complicated situations**, it is safest to call the police directly to avoid the other party's repentance or derivative legal risks after a private settlement. **Reminder**: Different regions may have specific rules and regulations (if some cities require losses below 2,000 yuan, you can negotiate by yourself), it is recommended to call the local traffic police for consultation. Keep evidence such as on-site photos, driving recorder videos, etc.
