Various tests are used to evaluate the roof strength of production vehicles. Dynamic rollover tests have been conducted as part of FMVSS 208 and static evaluation using FMVSS 216. The National Highway Transportation Safety Administration (NHTSA) is investigating methods to upgrade FMVSS 216 roof crush resistance to reduce injuries and fatalities in passenger cars, pickup trucks, vans, and multipurpose passenger vehicles from roof intrusion in rollover crashes (1). Roof crush intrusion is estimated to occur and potentially contribute to about 26 percent of serious or fatal injuries. Motor vehicle rollovers have been a concern for more that 30 years because they carry a very high risk of occupant death or risk compared to other types of crashes (2).
