So who is responsible for unbuckling all the kindergarteners’ seat belts in the event of a fire?
A 60 passenger vehicle which can potentially be filled with people unable to unbuckle themselves is more dangerous with seat belts than without.
The question is: how often do school bus wrecks happen, and in those wrecks, what causes most of the injuries/fatalities? If fire is the culprit, then maybe they do not need to be buckled in. Most of the fatalities I hear about in school bus wrecks are due to injuries sustained because the kids were not buckled in, such as the one that just occurred.
