American truck tonnage index declined 0.3% in April

May 22, 2025

Trucking activity in the United States slipped again in April as the freight market remained choppy early in the second quarter. Specifically, truck freight tonnage decreased 0.3% after contracting 1.5% in March, according to the American Trucking Associations' (ATA) advanced seasonally adjusted For-Hire Truck Tonnage Index.

"After surging 2.8% in February, and hitting the highest level since late May 2024, tonnage fell a combined 1.8% in March and April," said ATA Chief Economist Bob Costello. "Unfortunately, a recovery that was expected this year hasn't transpired as the industry deals with a freight market in flux from tariffs and softening economic indicators."

In April, the ATA advanced seasonally adjusted For-Hire Truck Tonnage Index equaled 113.0, down from 113.3 in March. The index, which is based on 2015 as 100, was up 0.1% from the same month last year, the fourth straight year-over-year increase, albeit the smallest increase over this period.

The not seasonally adjusted index, which calculates raw changes in tonnage hauled, equaled 112.0 in April, 2.2% below March's reading of 114.6.
