The week of May 26, 2026 is shaping up as one of the strongest spot rate environments of the year — driven in large part by the capacity squeeze that CVSA’s International Roadcheck created two weeks ago, combined with sustained demand across the Sun Belt and Midwest. National linehaul spot rates are averaging $2.79 per mile according to DAT data from late May, with reefer posting what analysts are calling its largest single-week rate increase on record and flatbed extending a 20-week consecutive gain streak to a new record high.
Where Rates Stand This Week: By Equipment Type
Here’s the current market snapshot based on FleetOwner’s rate tracking and DAT data heading into the week of May 26:
- Dry Van: National spot average $2.79/mile. The week of Roadcheck (May 12–14) saw a near-record weekly rate increase as volumes surged and capacity tightened sharply during the 72-hour enforcement blitz.
- Refrigerated (Reefer): Posted its largest weekly rate increase on record during Roadcheck, driven by reduced capacity and strong fresh produce movement. Reefer continues elevated heading into late May.
- Flatbed: Rose for the 20th consecutive week to a new record high, even as volumes moderated slightly. Strong construction and energy-sector demand continues to underpin flatbed pricing through spring.
For reference, April 2026 benchmarks per Dynamic Logistix: Van $2.68/mile, Reefer $3.12/mile, Flatbed $3.46/mile. The late-May surge represents meaningful week-over-week improvement across all three equipment classes.
Diesel Prices: Holding Elevated as the Summer Season Opens
Fuel costs remain a significant headwind for carriers. As of May 18, 2026, the U.S. on-highway diesel price averaged $5.596 per gallon according to EIA’s weekly retail price survey. Regional variance is significant: West Coast carriers are paying $6.524/gallon, while Gulf Coast operations have the lowest exposure at $5.122/gallon. The EIA’s May Short-Term Energy Outlook projects the national diesel average will remain around $5.36/gallon through Q2 before moderating to a full-year average of $4.76/gallon in 2026.
For dispatchers setting carrier rates, this means fuel surcharge conversations remain live. Any carrier quoting an all-in rate needs to have current fuel surcharge schedules factored in — particularly on longer lanes where a $0.50/gallon regional variance can swing a load’s profitability significantly.
“Dry van spot rates posted near-record weekly gains during Roadcheck as volumes surged and capacity tightened — reefer saw its largest weekly rate increase on record, and flatbed rose for the 20th straight week to a record level.”

Why Roadcheck Moves Markets — And Why the Effect Lingers
International Roadcheck is the single largest commercial vehicle inspection event in North America, with inspectors examining nearly 15 trucks per minute across a 72-hour window. In 2026, the event ran May 12–14 with CVSA focusing on ELD tampering (driver-side) and cargo securement (vehicle-side). When enforcement this visible concentrates this much attention on HOS compliance, a measurable slice of available capacity temporarily exits the market. That’s the mechanism behind the rate spike, and it’s why post-Roadcheck rate elevation typically persists 2–3 weeks after the event ends.
What’s notable in 2026 is that the underlying demand environment was already tightening before Roadcheck — the enforcement event accelerated a move that was already building. According to FleetOwner’s broader market analysis, spot and contract rates have been rising as capacity stays constrained, with tender rejection rates still elevated heading into the summer shipping season.
What Dispatchers Should Watch for Heading into June
- Monitor DAT load-to-truck ratios weekly: When ratios favor carriers, hold rates firm. When they soften, be ready to be competitive. DAT publishes these by lane and equipment type.
- Quote fuel surcharges explicitly: With diesel at $5.596/gallon nationally, never roll fuel into an all-in rate without documenting the assumption. If prices shift mid-haul, you need the mechanism to adjust.
- Build reefer carrier relationships now: Reefer is the tightest equipment class right now — produce season is just beginning, and carriers with track records on temperature-sensitive freight will be selective about who they book with.
- Don’t ignore flatbed demand: Twenty consecutive weeks of gains signals structural demand, not a spike. If you have flatbed carriers in your network, this is a premium moment to lock in dedicated arrangements before summer construction peaks.
- Expect June contract rate renegotiations: Shippers locked into Q1 contract rates are sitting below spot right now — many are about to leak freight to the spot market. Be positioned to capture it.
The freight market heading into June 2026 looks structurally tighter than the same period last year. Long-term contract rates are up approximately 8% since last fall, with further increases expected as shippers rely more on secondary capacity. Dispatchers who understand their lanes’ rate trends — not just today’s spot price but the 30-day direction — will be best positioned to retain carriers and serve shippers as the summer shipping season ramps up.
