Rolling guardrail could prevent fatal road accidents

the rolling guardrail consists of rotating barrels made of ethylene vinyl acetate and metal frames it has a luminescent quality which makes it highly visible to drivers during the night when a car hits the guardrail the barrels rotate to convert shock energy from the vehicle into rotational energy as a result the car is propelled forward back onto the road rather than breaking through the barrier the upper and lower frames of the guardrail can prevent the steer systems of both large and small vehicles from suffering a loss of function
