The motorcycle was knocked down, can the police station not investigate?

If no one is injured or property is damaged, under normal circumstances, the police station will not file a case. Because this behavior does not disturb public order, endanger public safety, infringe personal rights and property rights, and hinder social management, it is not an administrative violation. According to Article 2 of the Law of People's Republic of China (PRC) on Public Security Administration Punishment, disturbing public order, endangering public safety, infringing personal rights and property rights, and obstructing social management are socially harmful. If a crime is constituted in accordance with the provisions of the Criminal Law of People's Republic of China (PRC), which is not serious enough for criminal punishment according to law, the public security organ shall impose administrative penalties on public security according to this law.
