A road safety technology from South Korean company ETI CO LTD / Taebak has becoming viral online due to the fact that it contributes greatly to road safety.
The Road Roller System (RRS), consists of a sturdy steel tube (96cm height), between the plastic (yellow part) which spins around it. Prior to crash / accident, this barrier catches all the tension/impact and bend without causing great damage to the vehicle.
Due to twisting rollers, the vehicle first loses its inertia, then, it will change the vehicle’s trajectory sideways, in order to return the vehicle to the road. Simply, it does not allow the vehicle to fall or roll over in case of a crash. Brilliant right?
