Trucking activity in the United States contracted in December, marking the second decrease in as many months, according to the American Trucking Associations’ advanced seasonally adjusted For-Hire Truck Tonnage Index.
“For the first time since March and April, truck tonnage contracted for two consecutive months,” Bob Costello, ATA chief economist, said in a news release. “Tonnage fell 1.8% in November, bringing the two-month total decrease to 2.9%, pushing tonnage to its lowest level since January 2024. Sluggishness in factory output continues to weigh on freight volumes, but another drag on the index has been fleet growth at private carriers, which is holding back how much freight is flowing to for-hire carriers.”
In December, the ATA advanced seasonally adjusted For-Hire Truck Tonnage Index equaled 111.3 compared with 112.6 in November. The index, which is based on 2015 as 100, was down 3.2% from the same month last year.
The not seasonally adjusted index, which calculates raw changes in tonnage hauled, equaled 108.8 in December, 0.9% below November.
The seasonally adjusted decrease follows a sequential 1.8% drop in November.
Trucking serves as a barometer of the U.S. economy, representing 72.7% of tonnage carried by all modes of domestic freight transportation, including manufactured and retail goods. Trucks hauled 11.27 billion tons of freight in 2024. Motor carriers collected $906 billion, or 76.9% of total revenue earned by all transport modes.
Both indices are dominated by contract freight, as opposed to traditional spot market freight.
