Even if no one saw you, you cannot leave after accidentally hitting someone else's car. This behavior is a hit-and-run, which has many serious consequences: - **Legal liability** - **Civil liability**: Although no one noticed it at the time, the owner of the damaged car may find you through surveillance and other means in the future. Once found, you will be responsible for civil compensation such as the cost of vehicle repairs and reasonable travel losses caused to the other party due to the vehicle being out of use. - **Administrative penalties**: The traffic management department of the public security agency shall impose a fine of not less than 200 yuan but not more than 2,000 yuan, and may also impose detention for not more than 15 days. - **Criminal penalties**: If the damage caused by the collision reaches a certain level, such as a major traffic accident, causing serious injury, death, or major losses to public or private property, it may constitute a traffic accident crime and be sentenced to fixed-term imprisonment of not more than three years or criminal detention; if you flee after a traffic accident or have other particularly bad circumstances, you shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years; if you cause death due to fleeing, you shall be sentenced to fixed-term imprisonment of not less than seven years. - **Moral level** - **Lack of integrity**: Choosing to leave is an immoral and lacking integrity behavior, which is contrary to the values advocated by society. - **Inner condemnation**: Even if you can escape responsibility for a while, you will still feel condemned in your heart. Being under this kind of psychological pressure for a long time will have a negative impact on your mental health. The correct approach is to stop the car immediately, check the damage to the other car, actively look for the owner or leave your contact information, license plate number and other information, and wait for the owner to negotiate. This will not only show your responsibility, but also help to properly solve the problem and avoid a series of troubles that may arise later.
