A school bus accident is any accident, no matter how minor, involving a school bus while students are on board. In every instance, a law enforcement officer must respond to the scene and delays of up to one hour are common. When an accident occurs, it is the bus company's responsibility to determine if there are any injuries and the extent of the damages, and to notify the proper authorities, to include California Highway Patrol, the Driver's Supervisor (who must also respond to the scene), Ambulance (if necessary), and the WCTA Transportation Office. The Transportation Office will notify the parents and schools immediately upon determining the names of the students on board, the extent of the injuries (if any), the location of the accident, and a description of the accident.
