Results
The sample represented 42 cases involving 567 students. Five bus occupants were fatally
injured, two due to a side impact by a dump truck, one as a result of an external object
penetrating the occupant compartment, and two in a collision-induced fire. Twelve children
who had disembarked from their buses were killed, 11 being run over by the bus, and 1 who
was struck by a vehicle passing the bus.
The collisions involved 8 rollover incidents, 10 frontal impacts, 9 rear impacts, 5 right
side impacts and 5 left side impacts. There were two vehicle fires, and a single case of
occupant ejection. This situation is summarized in Table 1 Appendix "A".

The injury results are presented in Table 2,
Injuries to Occupants and Table 3,
Injuries to Pedestrians in Appendix A. In reporting injuries The Maximum
Abbreviated Injury Scale [5] was used in the case
reports for the incidents except where MAIS 6 was concerned. This rating system reports
injuries by a numerical scale (shown above).
The scale relates to injury and it is quite possible for a death to occur from a
non-codeable injury such as that resulting from smoke inhalation. For clarity, therefore, in
the tables found in Appendix A, AIS 1 to 5 is as
in the table shown here, but AIS 6 is replaced with a listing of fatalities. If an AIS 1
through 51 injury results in a fatality, it appears in the column for fatalities.

Non-complying bus
|
One type of collision merits special mention. It is possible for school
children to be transported in vehicles which do not meet the school bus
standards. These buses are often used to transport school sports teams to
events either during or after school hours. In two cases not included in
the tables, students were injured in buses which did not meet the
standards.
Injuries were definitely increased by the presence of overhead
racks which would not meet the requirements for head protection.
No changes to the school bus safety standards for new vehicles will
improve the level of safety that non-complying buses provide school
children.
The provincial/territorial authorities and school
boards should be encouraged not to use vehicles that do not meet the
safety standards for school buses in order to transport children.
