IN Brief:
- ATA's seasonally adjusted For-Hire Truck Tonnage Index fell 1% in July to 113.5.
- Tonnage was 0.5% below July 2025, although the first seven months remained 1.4% ahead year-on-year.
- Continued carrier capacity reductions could tighten selected lanes before national freight volumes show a broad recovery.
American Trucking Associations has reported a 1% decline in US for-hire truck tonnage during July, extending the uneven freight pattern that has characterised the market through the middle of 2026.
ATA’s advanced seasonally adjusted For-Hire Truck Tonnage Index fell to 113.5 from a revised 114.7 in June. The index uses 2015 as its base year of 100 and is weighted towards contract freight rather than spot-market movements.
July’s reading was 0.5% below the same month in 2025, reversing the 1.2% annual increase recorded in June. Across the first seven months of 2026, however, tonnage remained 1.4% higher than during the equivalent period last year.
The not seasonally adjusted index stood at 117 in July, 0.9% below June’s reading of 118. The figures continue a pattern in which periods of improvement have not developed into a consistent recovery across the national freight market.
ATA Chief Economist Bob Costello described truck tonnage as choppy and said freight remained lacklustre outside a small number of stronger areas, including construction activity associated with artificial-intelligence data centres.
He also pointed to capacity leaving the market as one factor behind improving conditions for the carriers that remain. That distinction is important because a healthier trucking market can develop without a large increase in the amount of freight being moved.
Rates and equipment utilisation can improve because fewer trucks are competing for roughly the same cargo. For shippers, that creates the possibility that transport capacity becomes harder to secure even while their own order volumes remain relatively subdued.
The adjustment is rarely uniform. Carriers can leave individual regions, equipment types, or customer segments before the change becomes obvious in national fleet statistics, producing localised tightening alongside weak headline demand.
Contract freight also behaves differently from the spot market. Because ATA’s tonnage index is heavily weighted towards contracted movements, it provides a useful measure of underlying volumes handled within established carrier relationships but does not capture every short-term change in urgent or excess freight.
A shipper can therefore see moderate national tonnage while experiencing much tighter conditions on a specific lane. Local construction activity, seasonal agriculture, plant production, port flows, weather disruption, or the closure of a carrier terminal can move available capacity away from the national trend.
The July decline follows a stronger opening to 2026. Tonnage improved during February, March, and April before weakening in May, followed by only a marginal increase in June.
The latest fall suggests that the earlier momentum has not developed into broad growth across manufacturing, construction, retail, and other major generators of road freight.
Industrial traffic is especially sensitive to the composition of economic activity. Large construction or manufacturing projects can create substantial regional truck movements while weakness in housing, consumer goods, or other sectors keeps the wider market subdued.
For distribution planners, the central question is how much excess transport capacity remains available if demand improves. Several years of weak rates have pressured carrier margins, encouraging fleet reductions, business exits, and tighter discipline around unprofitable freight.
That process can remove the buffer that previously allowed shippers to add trucks at short notice. Once spare capacity has gone, even a moderate seasonal rise in freight volumes can produce tighter acceptance, higher spot rates, and reduced flexibility.
The year-to-date increase of 1.4% shows that 2026 has not simply continued the contraction seen in weaker periods of the freight cycle. The problem is that growth was concentrated more heavily in the early months, while July has slipped below its year-ago level.
Carrier financial health therefore matters alongside the tonnage index. A market can remain weak enough to force operators out while simultaneously moving closer to the point at which the surviving fleet becomes insufficient for the next demand increase.
Shippers planning autumn and year-end freight should consequently monitor capacity as well as volume. Weak tonnage does not guarantee that the right trailer, driver, and carrier will remain available on every lane once seasonal requirements increase.
The current market sits between contraction and recovery. Freight is not falling sharply across the board, but neither has demand accelerated enough to produce sustained national growth.
If capacity continues to leave while volumes remain broadly stable, the next tightening cycle could begin before the headline tonnage figures look particularly strong. July’s 1% fall therefore says as much about the unevenness of the recovery as it does about the amount of freight moved during one month.
