Joshua Harman is an American entrepreneur, highway safety advocate, and whistleblower based in Bristol, Virginia. He is the co-founder of Selco Construction Services and SPIG Industry LLC, a highway guardrail manufacturing company. Harman is best known for filing a False Claims Act qui tam lawsuit against Trinity Industries over its ET-Plus guardrail end terminal, alleging the company had made undisclosed design changes that compromised the safety of the device. A federal jury awarded a $663 million judgment in 2015, the largest whistleblower verdict obtained without the assistance of the United States Department of Justice.[1] The judgment was overturned on appeal, with Trinity arguing that even if the design changes were not disclosed, the omissions were not material to the government's payment decisions.[2] The ET-Plus end terminal was subsequently discontinued and lost its eligibility for federal-aid reimbursement on December 31, 2017, after failing to meet the safety criteria set forth in the AASHTO Manual for Assessing Safety Hardware (MASH).[3][4]
