Washington 鈥 Trucking activity in the United States rose 0.1% in June after decreasing 3.2% in May, according to the 91制片厂鈥 advanced seasonally adjusted For-Hire Truck Tonnage Index.聽
鈥淲hile tonnage was little changed during June, there was a definite weakening in volumes during the second quarter as the index contracted a total of 4.1% during April and May,鈥 said 91制片厂 Chief Economist Bob Costello. 鈥淎fter five straight year-over-year gains, tonnage has now contracted from year-earlier levels for the last two months. While the U.S. economy remains on solid footing overall, the freight economy isn鈥檛 as strong. With that said, the decrease in capacity over the last year probably has fleets feeling a little better than volumes would suggest.鈥
In June, the 91制片厂 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鈥檚 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.聽
May鈥檚 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鈥檚 reading of 113.4.聽
