In the case of a traffic accident, even if no one is injured, whether or not to call the police usually depends on local laws and regulations and the specific circumstances. Generally speaking, it is usually a wise move to call the police if the accident caused significant property damage, involved multiple vehicles, caused a traffic jam, or there is any dispute over legal liability. Here are some considerations: 1. **Local regulations**: Some areas require calling the police in the event of a traffic accident with property damage above a certain amount. 2. **Insurance requirements**: Many insurance companies require a police report as evidence of a claim. 3. **Legal liability**: If the accident involves a violation of traffic laws, calling the police is a good way to ensure that the matter is recorded. 4. **Evidence record**: The police can provide an objective accident report, which can be very important for subsequent insurance claims and legal disputes. In uncertain situations, calling the police and seeking their advice is usually a safe choice. In addition, it is also important to make sure to exchange insurance information, take photos, and collect contact information for any witnesses at the scene of the accident.
