American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index increased 0.2% in August after rising 1.1% in July. In August, preliminary numbers show, the index equaled 115.3 (2015=100) compared with 115 in July.

“The evidence is growing that tonnage hit bottom in April and continues its slow climb upwards,” said ATA Chief Economist Bob Costello.

“However, year-over-year comparisons remain difficult as tonnage peaked in September of last year. As a result, it is unlikely that tonnage turns positive compared with a year earlier for at least a month or two longer. Most recently, freight continues to be mixed, with consumer spending and factory output flat to down.”

ATA said July’s increase was revised higher from numbers announced in an Aug. 22 press release.

Compared with August 2022, the seasonally adjusted index fell 2.3%, which was the sixth straight year-over-year decrease. In July, the index was down 1.2% from a year earlier.

The not seasonally adjusted index, which represents the change in tonnage actually hauled by the fleets before any seasonal adjustment, equaled 120.7 in August, 6.3% above the July level (113.6).

In calculating the index, 100 represents 2015. ATA’s For-Hire Truck Tonnage Index is dominated by contract freight as opposed to spot market freight.

Trucking serves as a barometer of the U.S. economy, representing 72.6% of tonnage carried by all modes of domestic freight transportation. ATA calculates the tonnage index based on surveys from its membership and has been doing so since the 1970s.
