DALLAS (AP) -- A Dallas manufacturer of guardrail systems found on many U.S. highways will resume shipments of the product after meeting safety standards in crash tests.
Trinity Industries Inc. said Friday it's getting inquiries for potential purchases of the ET-Plus Systems and will resume shipments as orders come in.
Critics had alleged that changes had made the systems more dangerous, turning their ends into lethal spears.
Trinity stopped manufacturing the guardrails in October 2014 after a federal jury found the company failed to tell regulators about the changes to the guardrails. The trial judge ordered Trinity to pay $663 million in damages, but Trinity has filed notice of appeal.
In March, federal officials said the design met safety standards during crash tests.
