The numbers are in for March, and they paint the clearest picture yet of a truckload market that has shifted gears. According to DAT Freight and Analytics, spot and contract truckload rates reached their highest levels in more than two years during March 2026, driven almost entirely by a fuel cost surge that pushed diesel to levels not seen since late 2022. Spot van rates closed the month at $2.52 per mile. Spot reefer came in at $2.97 per mile. Flatbed hit $3.09 per mile. And behind all three numbers sits a national average diesel price that crossed $5 per gallon and didn’t look back.
For small carriers and owner-operators who have been grinding through a prolonged soft market, these numbers carry meaning that goes beyond a monthly data release. Two-year rate highs signal that the structural dynamics in this market are shifting. Capacity is getting absorbed. Trucks are getting harder to find in key lanes. And shippers — even those with strong contract positions — are feeling pressure in the spot market that they haven’t felt in years. Whether this is the beginning of a sustained recovery or a fuel-driven spike that fades as diesel retreats is the central question for every carrier making equipment and capacity decisions right now.
Here is what the March data actually shows, what is driving it, and what small carriers should be doing with this information right now.
What DAT Found in March 2026
DAT’s monthly Truckload Volume Index rose across all three major equipment types in March. Van volumes climbed 12 percent, flatbed surged 18 percent, and reefer moved up 7 percent compared to the same period a year ago. Those are not marginal gains. An 18 percent jump in flatbed volume reflects real momentum in construction and manufacturing activity, two sectors that drive flatbed demand more than almost anything else. The van increase tells a parallel story about consumer goods and retail restocking. And the reefer bump aligns with early produce season activity beginning to ramp up on the West Coast.
On the rate side, the spot van average of $2.52 per mile represents an 11-cent gain over February. That may sound modest until you add the context: February’s number was itself elevated, and the month-over-month gain came on top of a volume increase, not in spite of it. Contract van rates came in at $2.72 per mile, up 20 cents from the prior month — a move that matters enormously for carriers with contracted freight as the gap between spot and contract continues to compress. When spot rates are within 20 cents of contract rates, the incentive to chase spot freight over honoring contracts shifts, and rejection rates begin to climb. DAT reported that tender rejection rates were running at approximately 14 percent during March, a level not seen since the capacity crunch of 2021 and 2022.
Diesel: The Primary Rate Driver
DAT was direct in its analysis: the rate gains in March were driven almost entirely by fuel cost recovery, not by a sudden explosion in freight demand. The national average diesel price surged over a dollar per gallon in the first quarter of 2026 due to geopolitical conflict affecting energy markets. During the week of March 22 through 28, the national average diesel price hit $5.375 per gallon — the highest weekly average since late 2022. The April average has settled at approximately $5.07 per gallon, which remains historically elevated and continues to push fuel surcharge calculations higher across all freight modes.
The practical effect of diesel at these levels is that fuel surcharges have ballooned, which inflates the published all-in rate figures even as underlying linehaul revenue per mile has not recovered at the same pace. Van fuel surcharges hit 61 cents per mile in March. Reefer surcharges reached 67 cents per mile. Flatbed surcharges climbed to 73 cents per mile. For carriers calculating net profitability, the key metric is what remains after fuel costs are subtracted from the all-in rate — and in many lanes, the linehaul margin is thinner than the headline rate numbers suggest. This distinction matters for owner-operators who are looking at $3-per-mile flatbed rates and calculating profitability without properly accounting for the diesel cost embedded in that surcharge figure.
Load-to-Truck Ratios and Capacity Tightening
Beyond the rate numbers, the most telling signal in the March data is the movement in load-to-truck ratios. In some lane markets, those ratios climbed above 60-to-1 by late March — meaning 60 loads were posted for every available truck. That is a level of tightness not seen since the freight boom years of 2021 and 2022. Available truck postings on the major load boards dropped to multi-year lows as a combination of factors reduced effective capacity: high fuel costs pushed some marginal owner-operators off the road, the winter weather earlier in the quarter had already disrupted capacity distribution, and seasonal demand from produce and construction hit simultaneously.
The Midwest was meaningfully tighter than the West Coast through most of March, reflecting a combination of manufacturing demand and agricultural pre-positioning. The West Coast began tightening later in the month as early produce season activity picked up out of the Salinas Valley and other California growing regions. This geographic divergence matters for carriers deciding where to position their equipment as April and May develop. The historical pattern holds that capacity tightness that starts in the Midwest and flatbed markets in March tends to spread across all geographies and equipment types as produce season fully activates in April through June.
Contract vs. Spot: The Gap Is Closing
One of the most strategically important data points in the March DAT report is the narrowing gap between spot and contract van rates. Contract van at $2.72 per mile versus spot van at $2.52 per mile leaves a 20-cent spread. During the soft market of 2023 and 2024, that gap ran 50 cents or wider, giving shippers a strong incentive to route freight through contracted carriers and giving contracted carriers a strong incentive to honor their commitments. As that gap closes, the dynamics flip. Carriers who were loading contracted freight at discounted rates relative to spot now face a real choice about rejection, and that behavioral shift is exactly what produces rising tender rejection rates and accelerating spot market activity.
For small carriers who operate primarily in the spot market, this environment is genuinely favorable. Higher spot rates, lower truck availability, and tightening load-to-truck ratios give spot-focused carriers more pricing leverage than they’ve had in two years. The risk is that the favorable conditions are partially fuel-driven, meaning if diesel retreats significantly in the second quarter, some of the all-in rate advantage disappears even if the underlying market remains firm. Tracking the linehaul component of rate offers separately from fuel surcharge — rather than looking only at the all-in per-mile rate — is the discipline that distinguishes profitable carriers in this environment from those who chase headline rates without understanding what’s left after diesel.
What This Means for the Broader Freight Market in Q2
The truckload market entering the second quarter of 2026 looks meaningfully different from where it stood 12 months ago. Carrier costs are up 16 to 17 percent year-over-year when fuel, labor, and equipment are factored in together. Rates are up roughly 20 percent year-over-year on a spot basis. If those two trajectories continue to move in parallel, margins remain stable. But if fuel retreats and rates drop in response, carriers who locked in volume at current rates win, while those chasing pure spot exposure face compression. The larger earnings signals will come from major carriers’ first-quarter reports, with J.B. Hunt releasing Q1 2026 results on April 15. Analyst expectations for a 24 percent year-over-year EPS rebound suggest the institutional view is that rate improvement is real and durable, not simply a fuel artifact.
The supply side of the equation is also worth watching. Class 8 truck orders surged 159 percent year-over-year in February 2026, a signal that large carriers are betting on the recovery and adding equipment. When those new trucks begin entering service in six to nine months, they will add capacity back into a market that is currently tight. That production-to-delivery lag means the favorable rate environment small carriers are seeing today may have a window that runs through summer 2026 before new equipment dilutes the capacity advantage. Positioning aggressively for spot freight and negotiating better contract terms now — while carrier leverage is elevated — is the strategic play that the March data supports.
How Small Carriers Should Position in This Market
The first move for any small carrier or owner-operator reviewing the March data is to benchmark their current per-mile rates against DAT’s market averages for their specific lanes and equipment type. If a carrier is running dry van in the Midwest and their average all-in rate is under $2.40 per mile, the market data says they are likely leaving revenue on the table. Rate benchmarking against the DAT published averages by lane — available through DAT’s trendlines portal — is the fastest way to identify where you are giving up margin versus where the market is already pricing fairly.
The second move is to separate fuel surcharge revenue from linehaul revenue in your records. Fuel surcharges move with the EIA’s weekly diesel price index and will drop if diesel retreats. Linehaul rates are what you negotiate — and in a market where tender rejections are at 14 percent and load-to-truck ratios are hitting multi-year highs, you have more negotiating leverage on linehaul than you’ve had in a long time. Use it. Push for higher linehaul on contract renewals, quote aggressively on spot, and make sure you’re not sitting in the same rate range you accepted during the soft market of 2024 when conditions were far worse for carriers.
Bottom Line
March 2026 produced the highest truckload spot rates in two years across van, reefer, and flatbed. Volumes rose double digits in most equipment categories. Load-to-truck ratios hit multi-year highs in key markets. And diesel at $5.07 per gallon pushed fuel surcharges to levels that are compressing shipper budgets and supporting carrier rate leverage simultaneously. The market conditions small carriers have been waiting for are showing up in the data right now. The window is real, but it is not infinite — new capacity being ordered today will arrive in six to nine months. The carriers who move aggressively on rate positioning in April and May will be the ones who capture the recovery fully before additional supply returns.
Questions Carriers Ask
What did the March 2026 DAT report actually show?
Spot and contract truckload rates reached their highest levels in more than two years. Spot van closed the month at 2.52 dollars per mile, reefer at 2.97, and flatbed at 3.09. Behind all three sits a national average diesel price that crossed 5 dollars a gallon and kept climbing.
Is this rate jump real demand or just expensive fuel?
DAT attributes the surge almost entirely to the fuel cost spike rather than a demand breakout. That distinction matters because fuel-driven rate moves behave differently than demand-driven ones. The report also shows load-to-truck ratios pointing to capacity tightening, which is the part worth watching for durability.
How should I position for the second quarter based on this?
The gap between contract and spot is closing, which changes the calculus on how much freight to keep on each side. The article covers what the March numbers mean for the broader market heading into Q2 and how small carriers should position. Make sure your fuel surcharge keeps pace, because a rate rally built on diesel only helps if you are recovering the diesel.
