This in-depth, nine month investigation by Chief Correspondent Brian Ross and Producer Cindy Galli was the first to disclose previously-secret company emails and documents, all pointing to an internal cover-up by guardrail manufacturer Trinity Industries. The company had modified a popular highway product without disclosing the changes to the government, as is required by law. That design change has now been blamed for injuries and deaths around the country. It also called into question the lack of oversight by the Federal Highway Administration. The first reports had an immediate impact as over a dozen states suspended purchases of the questionable guardrail end terminals in the days following the report. When we first reported our story, the Federal Highway Safety Administration said it considered the guardrail end terminals to be safe. Since our broadcast, more than 40 states have suspended the use of the devices and under growing pressure from congressional and state officials, the Federal Highway Administration has now ordered the company to conduct new safety tests which are currently ongoing .
