Back seat passengers are generally considered to be in the safest spot, but a study at the University of Buffalo shows how explosive that seat can be, when passengers in the back don't buckle up.
Apparently, the force of impact can turn those unrestrained passengers into deadly projectiles. University researchers studied the effects on drivers in a head-on collision when the rear passenger was unrestrained.
The unbelted crash dummies were nicknamed "back seat bullets" because they flew forward into the driver. The study also found that when the back seat rider was not buckled, head and chest injuries in the front seat were dramatically increased.
