Full Width Rigid Barrier In recent years car structures have become stiffer. This has helped to reduce lower leg and head injuries as the passenger compartment is less prone to collapse.  Higher structural stiffness however also means higher compartment decelerations, which need to be dealt with by the restraint systems…

Side Pole Some side impacts involve a vehicle travelling sideways into rigid roadside objects such as trees or poles. Often this is the result of a loss of control on the part of the driver, owing to speeding, misjudgement of a corner or because of a skid in slippery conditions.
