The National Highway Traffic Safety Administration (NHTSA) is conducting research programs to develop test procedures to reduce death and injury, in particular debilitating lower extremity injuries in frontal offset collisions. This paper presents updated results of Offset Deformable Barrier (ODB) crash tests conducted for the NHTSA. The ODB crash tests were conducted with 50th percentile male and 5th percentile female Hybrid III dummies fitted with advanced lower legs, Thor-Lx/HIIIr and Thor-FLx/HIIIr, to assess the potential for debilitating and costly lower limb injuries. This paper also investigates the implications that the ODB test procedure may have on fleet compatibility by evaluating the results from vehicle-to-vehicle crash tests.
