Crash cushions are especially meant to limit the seriousness of a collision with a fixed object, for example a fly-over supporting pillar. The standard guard-rail ramp-shaped beginning and end treatments are also to be considered as a danger zone. This situation can be resolved by using terminals. Furthermore, terminals offer as road restraint systems outstanding possibilities for roads outside city limits, where large lengths of guard-rail are not often applied as these are not in harmony with the scenery and influence the road-image too much. Crash cushions and terminals safeguard the safety of the road users at those locations where the risk of serious individual accidents with serious injury is present.
