Investigation: Guardrails

Posted: Updated:

A whistleblower lawsuit is raising serious questions about a highway safety device that is supposed to help protect motorists.  The recently unsealed lawsuit claims the device is defective. But the maker is fighting back saying the allegations are pure fiction and junk science. Becky Oliver has more about this Texas size legal battle between two competitors.

Trinity's written response to the story:
"To clarify, Mr. Harman is being sued by Trinity in part because he has published pictures of damaged guard rails and end treatments and falsely claims the pictures are evidence that the ET-Plus does not function to the NCHRP Report 350 standards.
Regarding the pictures, in every instance, the only way to assess the performance of the ET-Plus system, or any similar system, is to know multiple facts such as, to name a few, the weight of the vehicle involved, the orientation of the vehicle at impact, the angle at which the end terminal was impacted, and the speed of the vehicle at time of impact.  Without this and other information pertinent to each incident independently, it is impossible to determine how the end terminal system performed.   Any assumption or representation that the pictures show or suggest something more than a damaged guard rail would be erroneous.''
