Freight demand & truckload economics
ATA tonnage rises 0.8% in September, but year-over-year demand stays flat
· Source: American Trucking Associations
ATA's seasonally adjusted For-Hire Truck Tonnage Index increased 0.8% from August to 114 in September and was unchanged from a year earlier. The month improved after two declines, but the third quarter remained negative and ATA said capacity contraction—not strong freight growth—is improving market conditions for carriers.

September recovered from the August dip
ATA's advanced seasonally adjusted index rose from 113.1 in August to 114 in September. The year-over-year reading was flat, an improvement from August's 1.3% decline. For the first nine months of 2026, tonnage was up 0.9%, which ATA attributed mainly to strong gains from February through April rather than a steady late-year acceleration.
The raw monthly comparison moved lower
ATA's not-seasonally-adjusted index was 114.8 in September, 1.4% below August's 116.4. Seasonal adjustment and raw tonnage answer different questions, so the 0.8% headline should not be read as proof that every carrier or lane hauled more freight. ATA also noted that weak July and August readings left the full third quarter down sequentially and year over year.
Tighter supply is doing more work than demand
ATA Chief Economist Bob Costello said capacity continued contracting, improving the market for carriers despite soft tonnage. Transport Topics and CCJ independently reported the same figures and interpretation. Because ATA's index is dominated by contract freight reported by participating carriers, it is not a spot-load count, a rate index or a complete measure of private-fleet and parcel activity.
What carriers, brokers and shippers should infer
RoadHouse perspective: the data support cautious pricing firmness, not a broad volume boom. Compare the national index with tender rejections, accepted loads, revenue per tractor, empty miles and customer-specific forecasts. Shippers should budget for less excess capacity even when shipment growth remains modest.
Understanding the update
ATA released the preliminary September index on October 20, and Transport Topics, CCJ and The Trucker independently reported the result. The index is survey-based, focused on for-hire contract freight and subject to revision; it should be combined with rate, spot and shipment indicators before making a market call.
What it means for drivers and carriers
September's increase is encouraging but modest: carriers are gaining leverage mainly because capacity is shrinking, so operators should protect utilization without forecasting a demand surge that the tonnage data do not show.
Questions to consider
- Are the fleet's accepted loads and loaded miles improving in the same lanes as the national index?
- How much of pricing improvement comes from capacity exits rather than customer volume growth?
- What contract and spot indicators confirm or contradict the tonnage signal?
