The headline most people miss: American trucking is overwhelmingly a small-business industry. Roughly 52% of active carriers run exactly one truck, and the average active fleet nationwide is in the single digits. The mega-fleets get the headlines; owner-operators move the country.

Key findings

  • California leads the nation with 328,637 active carriers, ahead of Texas (193,728) and Florida (156,670). Together the top three account for 31% of all active US carriers.
  • Hawaii has the largest average active fleet at 23.2 power units per carrier, followed by Massachusetts (15.5) — typically a sign of consolidated regional fleets rather than owner-operator markets.
  • Among states with at least 1,000 active carriers, Florida is the most owner-operator-heavy market: 62% of its active carriers run a single truck.
  • The fastest-growing market relative to its size is Louisiana, where 90-day new registrations equal 1.7% of the active carrier base. Rapid new-entry markets deserve extra vetting care — young authorities are statistically overrepresented in fraud.

Power units and average fleet size are computed from active carriers reporting between 1 and 20,000 power units (filters out data-entry errors in the self-reported census). Owner-op % = share of active carriers reporting exactly one power unit. "New (90d)" counts registrations added in the trailing 90 days; "Revoked" counts carriers currently in revoked status.

Methodology & citation

Figures are aggregated nightly from the FMCSA registration census (the federal master file of all US motor carrier registrations) by MC Look Up. State assignment uses the carrier's physical address on file. Counts reflect the census as of the "data updated" date above; self-reported fields like fleet size are only as current as each carrier's latest MCS-150 filing. Full scoring and data documentation is on our methodology page.
