J.B. Hunt Transport Services has ordered 4,000 Wabash National DuraPlate dry van trailers that use a new rear impact guard designed for better protection against underride in collisions.

The trailers feature the RIG-16 Rear Underride Guard System, which is engineered to prevent underride in multiple offset, or overlap, impact scenarios. The guard reduces the risk of injury or death for individuals involved in an accident with the rear of a trailer.

The guard is made of high-strength steel and includes two additional vertical posts and a longer, reinforced bumper tube.

Production of the units for J.B. Hunt began in January. Wabash unveiled the technology at the American Trucking Associations’ Technology and Maintenance Council annual meeting in Nashville, Tenn., last month.

“At J.B. Hunt, we value safety above all else,” said John Roberts, president and CEO of J.B. Hunt. “We applaud Wabash National’s leadership and advancements in rear impact protection, and we’re proud to be the first fleet to specify the new rear impact guard design.”
