Two States Suspend New Guardrail Use, Cite Safety Concerns

— -- Transportation officials in two states said they are halting the use of a widely-installed guardrail end terminal that was the subject of an ABC News investigation while they further investigate potential safety hazards.

“Our internal observations, as well as our review of available information, indicates to us the ET-Plus guardrail end treatment is not performing as intended and could pose the risk of malfunctioning,” the Missouri Department of Transportation said today, referring to a newer version guardrail end piece. “Therefore, we are taking proactive steps to correct the situation. We are immediately stopping the further use of this product on Missouri’s highway system by taking it off of our approved products list, removing it from projects currently under construction and prohibiting its use on any future projects.”

Likewise, Massachusetts Department of Transportation officials told ABC News in an email Wednesday, “In light of a recent report raising questions about the performance of a specific guardrail end terminal, MassDOT has taken initial steps to halt the use of that end terminal while the agency conducts additional research.”

The Massachusetts state agency said that “if necessary, [it] will evaluate possible measures to repair or replace these end terminals already in use.”

The report referenced by the MassDOT was conducted by the University of Alabama-Birmingham and examined serious and fatal accidents in Missouri and Ohio. The study, first reported by ABC News, concluded that a redesigned version of a widely-used guardrail end terminal “placed motorists at a higher level of risk of both serious injury and fatality” than the original version. A MassDOT spokesman told ABC News this means no new ET-Plus model guardrails will be purchased for use on Massachusetts highways, nor will the guardrail be used to replace aging or damaged guardrails, while the investigation is ongoing.

The study was commissioned by the state of Missouri and The Safety Institute, a non-profit advocacy organization. However, Missouri transportation officials said their move today was not based on the University of Alabama-Birmingham report, but on their own internal review.

“Clearly I think there is a safety issue,” Sean Kane, President of The Safety Institute told ABC News. “It’s not just that study in isolation. What we’re seeing is real-world crashes around the country where the guard rails are not performing as intended.”

The ABC News investigation, which aired on “20/20” Sept. 19, reported that in 2005 Trinity Industries, the Texas company that makes the end terminals, changed the design of part of the guardrail end terminal -- shrinking a piece of metal from five inches in width to four. An internal company email, obtained by ABC News, showed that an official with the company estimated that the company would save $2 per guardrail with the change -- $50,000 a year.

Outrage Over Guardrail Crashes Tied to Lost Limbs, Death

Lawsuits filed against the company allege that small change altered the way the guardrail reacted to being hit from the front. In several graphic cases, the guardrail speared straight through the vehicle – severing motorists’ legs -- rather than bending back as designed.
