Truck Tonnage Holds at 117.8 in April, Highest Since Fall 2022
ATA's seasonally adjusted index stayed flat month-over-month but sits 3.5% above April 2025, marking four straight months without a decline.
What does the April tonnage index tell small fleets about freight demand?
The American Trucking Associations' seasonally adjusted tonnage index measured 117.8 in April 2026, unchanged from March but 3.5% higher than April 2025. The index has not declined in any month so far this year and now sits at levels last seen in fall 2022, before the two-year freight recession took hold.
Since the end of 2025, the index has climbed 4.7%. Through the first four months of 2026, tonnage is up 2.6% compared to the same period in 2025. ATA Chief Economist Bob Costello called April's flat reading "more impressive" given the cumulative gain since December.
Why the tonnage index matters to owner-operators and small fleets
Tonnage tracks the volume of freight moving on trucks, not the rate paid per mile. A rising index signals more loads in the system, which historically tightens capacity and eventually lifts spot and contract rates, though the lag between volume growth and rate improvement can stretch months. The 3.5% year-over-year gain in April suggests demand is climbing faster than new capacity is entering the market, a reversal from 2023 and most of 2024 when oversupply kept rates depressed.
For a 5-truck fleet running dry van or flatbed, the tonnage number matters because it reflects shipper activity across the entire truckload and less-than-truckload universe. When tonnage holds steady at multi-year highs, shippers eventually exhaust their contract capacity and turn to the spot market, where small fleets and owner-operators compete. The index does not tell you what you will earn per mile next week, but it does tell you whether the pipeline of freight is filling or draining.
How April's tonnage compares to recent LTL carrier reports
The ATA index aggregates truckload and LTL tonnage across the industry. Recent first-quarter earnings from LTL carriers show mixed volume trends that help explain why the national index stayed flat in April rather than climbing further. ArcBest Q1 tonnage up 6.5% as ABF Freight shipment weight climbs, driven by heavier shipments, while Old Dominion saw tonnage fall 8% year-over-year and reported softer April volumes tied to geopolitical uncertainty. XPO and Saia posted modest tonnage gains but noted uneven demand across lanes.
The divergence suggests tonnage growth is concentrated in certain sectors, industrial, construction, heavy freight, while consumer-driven lanes remain softer. Small fleets running dedicated or regional routes tied to manufacturing or construction are more likely to see the tonnage uptick translate into tighter capacity than those hauling retail or e-commerce freight.
What 72.7% of domestic freight tonnage means for trucking's share
ATA noted that trucks moved 72.7% of all domestic freight tonnage in the most recent full-year data, hauling 11.27 billion tons in 2024 and generating $906 billion in revenue. That share has held steady for years, meaning trucking's volume growth tracks the broader economy. When the tonnage index climbs, it reflects real industrial and consumer activity, not a shift of freight from rail or intermodal back to trucks.
For small fleets, the 72.7% figure underscores that trucking remains the primary mode for most shippers. When tonnage rises, it is not because trucks are stealing share: it is because more goods are moving, period. That makes the index a reliable leading indicator of freight market tightness, though the translation to rate improvement depends on how fast carriers add or retire capacity.
Why four months without a decline matters
The index has not fallen in any month since December 2025. That four-month streak is the longest stretch of uninterrupted growth since early 2022, before the freight recession began. Historically, sustained tonnage growth precedes rate recovery by two to four quarters, as shippers exhaust contract capacity and bid up spot rates to secure trucks.
The lag exists because carriers and owner-operators do not immediately pull capacity off the road when tonnage rises. Many fleets that survived the 2023–2024 downturn by cutting costs or running at break-even are still in the market, willing to haul loads at rates that do not yet reflect the tighter supply-demand balance. Only when those fleets exit, through bankruptcy, retirement, or voluntary shutdown, does capacity shrink enough to force rates higher.
What small fleets should watch in the next three months
The tonnage index is a volume measure, not a rate signal. Small fleets and owner-operators should track three additional data points to gauge when volume growth translates into better settlement checks:
- Spot rate movement: DAT and Truckstop.com post weekly averages. If tonnage stays elevated and spot rates begin climbing 5% or more month-over-month, the market is tightening.
- Contract rate renewals: Large carriers typically renegotiate annual contracts in Q2 and Q3. If shippers accept rate increases of 3% or more, it signals they expect sustained demand and are willing to pay to lock in capacity.
- Capacity exits: FMCSA revocation data and bankruptcy filings. If tonnage holds at 117.8 or higher and capacity continues shrinking, rates will rise faster than if new entrants flood the market.
The April tonnage reading does not guarantee rate improvement, but it does confirm that freight volume is no longer falling. For a 10-truck fleet that weathered two years of soft demand, that is the first necessary condition for a recovery.
