WFTS-TV Tampa, FL reports on its website with embedded video on its investigation that showed “a common type of guardrail made by a highway manufacturing heavyweight is responsible for four deaths and nine injuries in states like Texas, Tennessee, Florida and Virginia, according to lawsuits filed across the country,” but the guardrail “remains approved for use on national highways.” The guardrail is made by Trinity Highway Products of Dallas, and lawsuits against the company say “a small alteration to a device at the beginning of guardrails, known as an end terminal or guardrail head, causes the device to perform incorrectly.” The report explains how different states have handled the issue, noting that an Arizona official said that state “follows directions from the Federal Highway Administration (FHWA) and it has not received any advisories that would recommend changes.”
