Why School Buses Are Not Required to Have Seat Belts Essay
The short answer is that small school buses do in fact require seat belts; large school buses, with a few exceptions do not. Seat belts are not required on the larger school buses because both the U.S. Department of Transportation and Transport Canada, have determined that compartmentalization is the preferred occupant protection system.
To explain these differences in a greater detail we begin as follows; a small bus is categorized as a bus under 10,000lbs in weight, which are required by federal law to have seat belt systems on them due to the fact that they are closer in nature to the size of the average automobile and/or light trucks. The federal government requires a …show more content…
A term that was coined in the late 1960’s by researchers from UCLA. It basically was termed compartmentalization, denoting a safety envelope or “compartment” around the passengers in school buses. The fundamental idea was that if a crash were to occur, that the child may be thrown around within this compartment but the design of the seat compartment would essentially absorb the crash force and protect the child.
After extensive research during the 1970’s the Department of Transportation and its agency, the NHTSA determined that the safest and most practical arrangement for school bus seating would be this “compartmentalization” concept. Accordingly, the new safety regulations that were effective for school buses manufactured on or after April 1, 1977, included this requirement among other improvements made that year.
Student riders are surrounded by a compartment of energy absorbing material – 4inch thick foam seats, seat frames that bend to absorb crash forces, and a vehicle designed to absorb energy. The idea is the crash force will be dissipated or absorbed before they get to the student passengers. However, compartmentalization doesn’t work well in rollover crashes, hence one of the
