It started with a hunch about malfunctioning highway guardrails. It led to the biggest known whistle-blower award in U.S. history.
Joshua Harman, a Virginian with two small highway safety companies, made a discovery in late 2011 that perhaps only a guardrail maker could: A big competitor had changed the dimensions of its roadside safety device by as much as an inch here and there, he said, without telling federal regulators.
As designed, Trinity Industries Inc.’s ET-Plus system was meant to turn the end of a guardrail into a de facto shock absorber. The altered units, as Harman saw it, were locking up when hit, spearing cars and their occupants.
