Joshua Harman, co-founder of guardrail manufacturer SPIG Industry, investigated Trinity Industries’ ET-Plus end terminal during a 2011 patent dispute and alleged that Trinity had introduced five undisclosed design changes beginning in 2005. The changes included narrowing the guide channel from five inches to four, which Harman said could cause the terminal to lock during a crash instead of allowing the guardrail to slide and absorb energy. Harman’s independently compiled accident research reported more than 40 deaths and over 100 injuries associated with redesigned terminals; those figures were his investigation’s findings, not a final court determination of causation.
In 2012, Harman filed a False Claims Act qui tam suit, alleging Trinity improperly obtained federal reimbursement eligibility without notifying the Federal Highway Administration. A federal jury in October 2014 found Trinity liable for $175 million, and in June 2015 the court trebled damages to $663 million, awarding Harman about $199 million plus $19 million in legal fees. The Fifth Circuit reversed in October 2017, holding that nondisclosure was not material because FHWA had continued treating the product as eligible. Nonetheless, the ET-Plus lost federal-aid reimbursement eligibility on December 31, 2017, after failing updated MASH safety criteria, and Trinity divested its highway-products business in 2021.
