The 2025 FleetOwner 500: For-Hire list ranks the most prominent motor carrier and commercial fleet operations in the U.S. by total registered power units. Released in February, the FO500 saw many ranking shifts after a busy 2024 of carrier acquisitions, mergers, consolidations, and expansions.
In addition to ranking the largest for-hire fleet operations overall, FleetOwner breaks down these companies into categories based on equipment, cargo types, and industry segments. This media gallery focuses on refrigerated fleets.

Refrigerated fleets use temperature-controlled trailers to transport goods that must be kept at a specific temperature. This includes cargo such as perishable foods, pharmaceuticals, flowers, and more. New to this media gallery is TransAm Trucking at No. 6. The fleet jumped 83 spots in the FO500 this year. The other fleets have been featured on this list before, though Hirschbach jumped into the No. 2 spot over Marten Transport.
