Trucking activity in the United States rose 0.1% in June after decreasing 3.2% in May, according to the American Trucking Associations’ advanced seasonally adjusted For-Hire Truck Tonnage Index.
In June, the ATA advanced seasonally adjusted For-Hire Truck Tonnage Index equaled 113.1. The index, which is based on 2015 as 100, decreased 0.1% from the same month in 2025, which was better than May’s 0.7% drop. During the first half of the year, tonnage was up 1.4% from the same period last year thanks to strength in the first quarter. In 2025, the tonnage index was flat compared to the 2024 average.
May’s reading was revised down from what was first reported in our June 23rd press release.
The not seasonally adjusted index, which calculates raw changes in tonnage hauled, equaled 116.5 in June, 2.7% above May’s reading of 113.4.
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. The tonnage index is calculated on surveys from its membership and has been doing so since the 1970s. This is a preliminary figure and subject to change in the final report issued around the 5th day of each month. The report includes month-to-month and year-over-year results, relevant economic comparisons, and key financial indicators.
