I see no mention of a standard(s). In the absence of a standard to which the guardrails must adhere, it is the fault of whomever permitted the guardrail to be installed. Not the manufacturer.

From Roadside Design Guide, American Association of State Highway Transportation Officials, 2004, pages 5-10 to 5-23
Barriers are divided into three groups, based on the amount they deflect when struck by a vehicle and the mechanism the barrier uses to resist the impact forces. In the United States, traffic barriers are tested and classified according to the AASHTO Manual for Assessing Safety Hardware (MASH) standards, which recently superseded Federal Highway Administration NCHRP Report 350. Barrier deflections listed below are results from crash tests with a 2,000 kg (4,400 lb) pickup truck traveling 100 km/h (62 mph), colliding with the rail at a 25 degree angle.[7]
There are strict standards for the materials, design, and installation of all barriers (guardrails) and the issue at the center of this discussion is whether the manufacturer changed the approved design and construction without notification to the feds.

Thanks for the info. Looks like the manufacturer has a bit of a legal battle ahead of them.

IF the manufacturer knowingly misrepresented their crash test data, you better believe they're at fault. Possibly even criminally.

Yes I agree, especially since there are apparently standards. There is likely a very strict re-qualification necessary for process/design changes. Bypassed requal and related deaths... I bet the investors are not too pleased.
Obviously if it weren't for distracted drivers, stupid decisions, drunk drivers, etc. then the accidents wouldn't have happened.
In 2005, they changed the design of their guardrails without notifying the Federal Highway Administration (which is illegal). In addition to notifying the FHA about these changes that were made, they are supposed to have crash tests. They did have those crash tests; however, the court has found that they never disclosed the results to authorities. Well, what were the results you ask? 5 failed crash tests!
The following states have banned Trinity Industries’ ET-Plus guardrail system: Oregon, Nevada, Arizona, Colorado, Missouri, Mississippi, Virginia, Louisiana, Vermont, New Hampshire, Massachusetts, and Connecticut.
