China's criminal law is divided into public prosecution and private prosecution cases. As a public prosecution case, traffic accident crime needs to go through three organs and three stages, namely the investigation stage of the public security organ, the review and prosecution stage of the procuratorate, and the trial stage of the court.
 China's laws stipulate that all cases requiring public prosecution shall be reviewed and decided by the People's Procuratorate.
 If the People's Procuratorate believes that the criminal facts of the criminal suspect have been found out, the evidence is reliable and sufficient, and criminal responsibility should be investigated according to law, it shall make a decision to prosecute, file a public prosecution with the People's Court in accordance with the provisions on trial jurisdiction, and transfer the case files and evidence to the People's Court.
