I have been a public school bus driver for 15 years and union steward for half that. The numbers in the study don't make any sense. First of all, there are 26 seats on a full size school bus, the legal capacity is 3 students per seat which would be 72 students. If the study served 462 students on 15 buses, that is 31 students per bus while claiming operating at 'near capacity'. Thats less than 1/2 capacity. The study claims using 2 students per seat, spaced a minimum 2.5 feet apart. This figure is physically impossible to achieve due to the seat spacing design of the bus which, by the way would be 52 students at two per seat, not 31 as the study claims. It is my professional opinion that this safety study of Covid transmission on school buses is a farce.
