October preliminary North America Class 8 net orders were 30,600 units, down 5.2% year over year. Complete industry data for October, including final order numbers, will be published by ACT Research in mid-November.

“After a strong start to the opening of 2025 order books in September, MD and HD orders took a step back in October,” said Kenny Vieth, ACT’s President and Senior Analyst. “On a seasonally adjusted basis, Class 8 orders fell 30% from September to 24,500 units, a 294k SAAR.”

In terms of medium duty, Vieth added, “Over the past several years, MD Classes 5-7 orders have been remarkably consistent, if on a slowly deflating trajectory into still-elevated truck and bus backlogs. With the caveat that one month does not make a trend, October orders moved sharply from the prevailing trend. Preliminary NA Classes 5-7 orders fell 5,800 units, or 27% y/y to 15,900 units.”

ACT’s State of the Industry: NA Classes 5-8 report provides a monthly look at the current production, sales, and general state of the on-road heavy and medium duty commercial vehicle markets in North America. It differentiates market indicators by Class 5, Classes 6-7 chassis and Class 8 trucks and tractors, detailing measures such as backlog, build, inventory, new orders, cancellations, net orders, and retail sales. Additionally, Class 5 and Classes 6-7 are segmented by trucks, buses, RVs, and step van configurations, while Class 8 is segmented by trucks and tractors with and without sleeper cabs.
