According to China's traffic laws and regulations, if you accidentally hit someone else's vehicle while driving, you **cannot** leave the scene without permission, even if there are no witnesses. According to the relevant provisions of the "Road Traffic Safety Law of the People's Republic of China", after a traffic accident, the driver has the following obligations: 1. **Stop immediately**: Make sure the vehicle is parked in a safe place that does not affect traffic. 2. **Protect the scene**: Turn on the hazard warning flashers and set up warning signs when necessary to prevent secondary accidents. 3. **Find casualties**: Confirm whether anyone is injured and call the emergency number immediately if necessary. 4. **Exchange information**: Exchange name, contact information, and vehicle information (such as license plate number, model, color, etc.) with the other driver. 5. **Report**: If the accident causes personal injury or property damage, it is usually necessary to report the accident to the local public security traffic management department within the prescribed time. Leaving the accident scene without permission, even if there are no serious consequences, may be considered "hit-and-run", and you will face legal liability, including fines, driver's license deduction points, and even detention. Therefore, it is recommended that you follow the above steps to properly handle the accident after it occurs to ensure that the legal rights and interests of yourself and others are protected. **Please note**: The specific handling process may vary from region to region. It is recommended to contact the local traffic management department or seek legal advice as soon as possible after the accident to ensure compliance with local laws and regulations.
