The following paper presents data derived from sled test experiments, full-scale vehicle crash tests as well as an in-depth analysis of accident data which suggest that occupants are not typically injured even in collisions with rigid longitudinal barriers if the vehicle remains upright and is smoothly redirected to a safe stop. Ensuring barrier performance which will prevent vaulting, rollover, penetration or severe snagging appears to be the most effective method of providing the maximum protection to occupants of vehicles involved in longitudinal barrier collisions.
