The Crash barrier absorbs maximum impact of the vehicle and ensure minimum damage to the vehicle and the occupants.
During night and bad weather the barriers act as a visual guide to the drivers
The impact energy is reduced to the maximum possible extent, due to the friction between the W/Thrie beams and the vehicle, enabling gradual deceleration of the vehicle into the carriage way.
The vehicle is prevented from skidding back into the carriage way, thus avoiding the risk to flowing traffic.
