The evolution of accident investigation procedures is traced from early railway accidents, through the work by De Haven on light aircraft accidents to the first in depth studies of road crashes. Individual multi-disciplinary teams addressed many biomechanical issues in the 1960s and 70s, leading to larger cooperative projects such as NASS and CCIS. Examples are given of the linking of field accident research with experimental biomechanics, and the importance of population variations is emphasised. The optimisation of vehicle crashworthiness requires good accident investigation of the mechanisms of injury as well as detailed crash data. The limitations of current test tools for road user protection is discussed.
