How to write a letter of understanding for minor traffic accidents?

On 20 10 12.30, the driver XX had a traffic accident on the light section of Lanhai Expressway, resulting in the death of XX. Afterwards, driver XX was criminally detained by the public security organs and released on bail pending trial. After the accident, XX paid the funeral expenses of the deceased, and actively negotiated compensation with our family members, and reached the Opinion on Consultation and Mediation of Traffic Accidents on 20 10 12.30. Now XX has paid all the compensation in the previous period of 654.38 million yuan. For the death of XX, the driver XX expressed deep regret to our family. In the process of negotiation, we learned that XX's family was also very difficult, but he still made compensation in various ways. We think his repentance is very good. As the families of the deceased, we can also understand XX's negligence. Therefore, the relevant judicial organs are requested to give him a lighter punishment for his criminal responsibility. Signature of the family members of the deceased in XX County People's Procuratorate of XX County Public Security Bureau: Note: The criminal letter of understanding itself has no fixed format. The purpose of issuing letters of understanding is to reduce the punishment of criminal suspects, and some can release criminal suspects on bail pending trial. Therefore, the letter of understanding is sent by the victim to the criminal's family, and is generally handled by the responsible lawyer for the criminal suspect. But if the circumstances are minor and you don't need to hire a lawyer, you can refer to the format of this letter of understanding. If the premise of the letter of understanding causes harm to the victim, it shall be clearly stated that the compensation has been reached and the actual compensation has ended. If there is no harm to the victim, there is no need to express it, but the focus of the letter of understanding should be clear that the victim has understood and the victim requests to be exempted from investigating the criminal responsibility of the defendant (criminal suspect).
