Vehicle restraint systems in the initial and final constructions category are installed at the end of crash barriers to minimize the impact of vehicle accidents. The vehicle restraint systems in this category are designed to stop or deflect vehicles in the event of a possible collision in order to prevent serious damage to vehicles and occupants as well as to the crash barriers.

Initial and final structures are used along roads and highways to protect vehicles and their occupants from obstacles. These can be trees, pillars or slopes, for example. The aim is to prevent vehicles from leaving the road and getting into dangerous situations.

The various systems are used depending on the specific requirements of the location. End structures absorb the energy in the event of a collision, while initial structures ensure that vehicles are kept away from dangerous obstacles.
