ATA: Truck Tonnage Edged Down in August from July Maria Eugenia Garcia DTN Energy Editor HOUSTON, TX (DTN) -- American Trucking Associations' advanced seasonally adjusted For-Hire Truck Tonnage Index dropped 0.5% to 112.7 in August after dropping 1.2% in July. "The truck market has certainly flipped this year, but recent tonnage levels confirm this is due to reduced capacity, not robust demand," said ATA Chief Economist Bob Costello. "Truck tonnage was down in four of the last five months. It is down 4.3% from the recent peak in March, and it has fallen from year-earlier levels in three of the last four months. Because of all the supply constraints, however, the market is generally better," Costello said. The not seasonally adjusted index, which represents the change in tonnage actually hauled by fleets before any seasonal adjustment, equaled 116.1 in August, below July's reading of 116.7. 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 72.7% 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. ATA calculates the tonnage index based on surveys from its membership and has been doing so since the 1970s. (c) Copyright 2026 DTN, LLC. All rights reserved.
