1 1. 16 Causes of the Extraordinary Traffic Accidents in Zhengning County, Gansu Province

After preliminary analysis, the main causes of the accident are as follows: First, the driver of the school bus is weak in safety awareness, seriously violating the rules and overloading, and the left lane is speeding and retrograde. Second, kindergartens have modified vehicles privately to avoid supervision, and the number of vehicles limited to 9 is now modified to no seats. Third, Li Jungang, the director of the kindergarten, has a weak sense of safety responsibility and fails to fulfill the responsibility of the first responsible person (there are 737 students and 28 faculty members in the private kindergarten, and four school buses are arranged to pick them up). Fourth, due to the influence of foggy weather, truck and school bus drivers failed to deal with emergencies. Fifth, the supervision of education and traffic police departments is weak.
