Reported volumes of used Classes 3-8 truck sales improved in December. Volumes were consistent among channels on a sequential basis.

All three segments, auction, retail and wholesale, saw increases compared to November's activity. However, all three segments continued to lag on a year-over-year basis, according to State of the Industry: U.S. Classes 3-8 Used Trucks, published by ACT Research.

"The industry continues to look to improving new truck sales to provide some much needed relief for the used truck inventory shortage," says Steve Tam, ACT vice president, commercial vehicle sector. "Concerning pricing, our expectation remains unchanged. We believe year-over-year pricing growth will continue to slow. Prices will not necessarily fall, but just grow at a slower rate," he added.
