Trinity Guardrail Study Finding Fatal Flaw Faulted in New Review

A study linking deadly highway crashes to a Trinity Industries Inc. guardrail system was found to have fundamental flaws by independent reviewers brought in after states banned the safety devices.
At least 42 states and the District of Columbia have suspended installations of the system, some of them based partly on the study of Trinity’s ET-Plus guardrail end terminal, which is designed to absorb the impact of a crash. The study found that the device was almost four times more likely to be involved in a fatal crash than its predecessor model.
