One of our buses got hit by a car yesterday morning, thankfully nobody was hurt but it got me thinking on the seatbelt thing again. I did a little research and found this piece below. Figure it would be for some interesting discussion.
The short answers to why seat belts are not mandated on school buses are safety issues, economics, and liability.
The National Highway Transportation Administration (NHTSA), one of the most influential government agencies when it comes to public safety on roadways, has stated that current school buses are among the safest forms of transportation available. After studying the results of crashes involving school buses, the NHTSA stated that there was no compelling reason to believe the use of seat belts on school buses should be federally mandated. Most accidents involving school buses were either frontal or rear collisions, which means that passengers were protected by a safety feature called compartmentalization.
