American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index rose 3.3% in October, following a 1.9% decline during September. In October, the index equaled 147.6 (2000=100), up from 142.9 in September.

Compared with October 2016, the index surged 9.9%, which was the largest year-over-year increase since December 2013. In September, the index increased 6.3% on a year-over-year basis. Year-to-date, compared with the same 10 months in 2016, the index is up 3.1%.

ATA also revised its September decline in the index down to a 1.9% drop from the previously reported 0.9% decrease.

The not seasonally adjusted index, which represents the change in tonnage actually hauled by the fleets before any seasonal adjustment, equaled 151 in October, which was 5.1% above the previous month (143.7).

“Continued improvement in truck tonnage reflects a much stronger freight market,” said Bob Costello, ATA chief economist. “This strength is the result of several factors, including consumption, factory output, construction and improved inventory levels throughout the supply chain. Additionally, the 6.7% rise in tonnage over the last four months suggests to me that retailers are expecting a good holiday spending season.”
