The effectiveness of seat belts — both lap belts and shoulder straps — in reducing injuries and deaths in automobile accidents is widely documented in studies and backed up by anecdotes from first responders. But when it comes to requiring seat belts on school buses, safety experts are divided … A 2010 study by the University of Alabama study drew a similar conclusion, reporting that “enforcement by the driver is almost impossible” and quoting drivers’ concerns that they could be held legally liable if a child was injured while not using his or her seat belt properly.
