As a mode of transportation, buses are generally safer than riding in a passenger vehicle. They are larger and heavier and can withstand more force than an ordinary automobile. Passengers sit several feet above the road surface so they seldom are exposed to blunt force trauma from another vehicle. Still, bus passengers suffer serious and sometimes fatal injuries. In one tragic case in Southern California recently, a 16-year old was killed on a double-decker tour bus that led to a multi-million dollar verdict.
