In response to your first #5, there are ways to prevent the crushing and dragging injuries. I drove a school bus in NC back in the 70’s (when high school students were still allowed to be bus drivers). I remember the training. The most dangerous part of driving the bus was the pasenger stop. They taught us that there was 14 steps to a passenger stop. One step in particular was, “Count and recount.” If they are getting on the bus, you count the kids before you open the door, then recount them as they get on. Or if getting off, count them as they leave, then again as they walk away from the bus stop. DO NOT MOVE THE BUS UNTIL YOUR COUNTS MATCH!!!
The bus driver has enough to do without worrying about **14** steps. Fourteen steps? Wow! That’s a perfect prescription for crushed and dragged children.
In the dragging injuries and deaths. The child leaves the bus, and since he is not seen, the driver assumes that he has fully exited and left the vicinity of the bus.
Then there is the occasional crushing that happens when the bus backs up and the child is behind the bus.
There should be bus monitors on all buses to see that the children enter and exit the bus safely, and fully cross the street. Where humans are involved there will always be accidents. The goal should be to reduce these accidents to as low as possible.
