The freight market entering the second half of March 2026 is sending a clear message: the seasonal tailwind is here, but it’s arriving alongside a layer of complexity that straight rate-chasing will not navigate. Dispatchers who understand the full picture — not just today’s load board rate — are the ones who will lock in their best weeks of the year right now.
- Shift reefer carriers to Nogales and Phoenix produce lanes now; narrow, repeatable window builds broker relationships for peak produce season.
- Prioritize flatbed loads tied to spring construction and tariff pre-buys; use 48-hour lookaheads to position carriers in strong outbound markets.
- Call three brokers and keep carriers ready to load within two hours to capture pre-tariff surges and avoid post-surge market lulls.
Reefer: The Seasonal Engine Is Turning Over
Refrigerated freight is showing the clearest momentum of any segment this week. After a subdued January and February — during which Florida’s produce crisis suppressed outbound volumes — the Southeast is beginning to recover. More importantly, the Nogales, Arizona corridor — the primary entry point for Mexican produce — is seeing its strongest spring volumes since 2023. Cucumbers, bell peppers, tomatoes, and squash are moving heavy as the Sonoran growing season reaches peak export. Reefer rates out of Nogales and Phoenix into the Midwest and Northeast are running $2.45 to $2.80 per mile depending on destination.
For dispatchers with reefer carriers: this is not the week to let your carrier sit idle chasing a slightly better dry van rate. The spring produce window is narrow, predictable, and repeatable. Aggressive positioning in these lanes right now builds the broker relationships that pay dividends in May and June when produce freight hits its absolute peak.
Flatbed: Holding the Strongest Position in Years
Flatbed continues to be the market’s standout performer. Spot rates have held in the $2.65 to $2.75 per mile range nationally — a level not sustained for this long since the freight boom of late 2022. The spring construction surge is accelerating across the Sun Belt, Mountain West, and Midwest, absorbing flatbed capacity faster than new trucks can enter the market. Tariff-driven pre-buying is also creating lumpy but high-value flatbed demand on industrial corridor lanes into Chicago, Detroit, Cleveland, and Pittsburgh as manufacturers front-load purchases of steel, aluminum, and machinery ahead of anticipated tariff increases.
Dry Van: Selective but Not Soft
Dry van spot rates have pulled back to $2.05 to $2.20 per mile nationally after February’s weather-driven spike. The strongest lanes right now: anything moving into the Southeast from the Midwest and Northeast, and outbound California lanes on I-10 and I-40 where retail freight is heavy heading into spring inventory restocking. Lanes to avoid this week: inbound to the Southeast (heavy capacity build), Chicago outbound to the Northeast (abundant capacity, compressed rates), and upper Midwest drop trailer pools (tight rates, picky receivers).
The Tariff Wild Card
Ongoing uncertainty around U.S. trade policy with Canada, Mexico, and China is creating two freight behaviors dispatchers need to understand. Pre-tariff freight surges are real and exploitable — when tariff announcements hit, shippers move product fast, creating short-notice premium loads. But only dispatchers with the broker relationships and carrier availability to respond in under two hours actually capture them. Post-tariff lulls are equally predictable: after a buying surge, a short demand dip follows as shippers work through inflated inventory. Don’t let your carrier get stranded in a weak outbound market on the back end of a surge.
Three Dispatch Moves to Make This Week
Transition any reefer carrier from general freight to produce lanes immediately — the window is open now. Target construction-adjacent flatbed lanes in the Midwest with 48-hour lookaheads, booking loads that position your carrier in strong outbound markets rather than dead zones. And call three brokers this week to introduce yourself as a pre-tariff surge resource, telling them you have carriers available on short notice for time-sensitive loads. Tariff-driven surge freight goes to dispatchers who raised their hand before the opportunity — not to those who showed up after the load was already covered.
The mid-March market is handing dispatchers a real opportunity. The season is cooperating, freight is moving, and tariff volatility — while uncertain — is creating premium load pockets for those positioned to respond.
