ATA's Truck Tonnage Index up slightly in September

Line chart showing September 2026 data with 0.8% increase, tracking values between 110-120 from January 2022 to July 2026

Trucking activity ticked up in September 0.8% after falling 0.2% in August, the American Trucking Associations (ATA) says. 

"Truck tonnage ended the quarter on a better note, but weakness in July and August pushed the third quarter reading into negative territory both sequentially and from a year earlier," says Bob Costello, ATA's chief economist. "We are seeing soft tonnage levels but capacity is still contracting, which is leading to a better market for motor carriers."

The index is based on 2015 as 100. 

The not seasonally adjusted index calculates raw changes in tonnage hauled. It was 114.8 in September, down 1.4% from August's 116.4.
