HIGHWAY guardrail systems in the US made by Trinity Industries Inc and Road Systems Inc have "safety performance issues" in some real-world crash scenarios, the Federal Highway Administration (FHWA) said last Friday as it urged a national overhaul of standards to better protect American drivers.
The regulator released a report citing "performance limitations" of five guardrail products, three by Trinity and two by Road Systems. The agency found the models experienced performance shortcomings in side impacts and shallow-angle collisions with the guardrail's end, sometimes resulting in penetration of the vehicle.
