I have been a public school bus driver for 15 years and union steward for half that. The numbers provided in this study just don't add up. First of all, there are 26 seats on a full size school bus, so if the study operated at 'near capacity' that would actually be three students per seat and operate at the legal capacity if 72 students. This study suggests that 462 students were served on 15 school buses, that equals 31 students per bus, thats actually less than half capacity. Also, the study proposes that two students per seat were spaced at a minimum of 2.5 feet apart at, which is physically impossible due to the seat spacing design of the school bus. It is my professional opinion that all this study does, is provide a false sense of security for parents, students, drivers, staff, and administration, and should be disregarded completely.
