The FleetOwner 500: For-Hire is our annual snapshot of the commercial fleet landscape, based on data as of December 31, 2025. But the trucking industry is never idle. Just weeks into the new year, No. 11 Werner Enterprises announced its acquisition of No. 55 FirstFleet, which would have pushed Werner into the Top 10 if the transaction had closed a month earlier.
This is the fourth FO500 since we revised our data-gathering process. Since 2023, we have partnered with ProsperFleet, which uses information companies file by December 31 on Form MCS-150 with the Federal Motor Carrier Safety Administration (FMCSA) to count power units, trailers, and drivers. This ensures a consistent playing field for all carriers operating in the U.S.
Analysts at ProsperFleet also use companies’ websites, press releases, and business databases to roll U.S. Department of Transportation (USDOT) operating entities into a single parent company. ProsperFleet then cleanses, validates, standardizes, and enhances company and contact information to create a complete fleet view. For companies with subsidiaries and divisions with USDOT numbers, the vehicle counts of the subsidiaries are included in the parent company’s total on the FO500.
