Used Class 8 truck sales fell to 2,239 units in January - a 12% decline from December and a 3% decline year-over-year, according to a report from ACT Research.

The drop off in sales was not unexpected as a seasonal decline in January has been common, according to Steve Tam, vice president of the commercial vehicle sector with ACT.

“The pull back in volumes was in line with a seasonal pattern we’ve seen in four of the last six January’s said Tam. “All three segments of the market – auction, retail, and wholesale – experienced slowing.”

Pricing was up 7% year-over-year despite the average age of used trucks increasing by 1%. However, pricing is not expected to grow in 2015.

“Two catalysts that will keep a lid on pricing growth this year are tougher comparisons and, hopefully some relief on the inventory front,” said Tam.
