Where US Trucking Capacity Actually Sits — State by State

Ask where American trucking capacity is concentrated and most people guess Texas — it's the natural hub of long-haul freight between the coasts, Mexico, and the Gulf. The FMCSA's own registration data tells a more specific story: capacity, measured by the number of actively registered carriers, concentrates around the country's largest freight-generating and freight-consuming metros first, and that ranking doesn't line up with population alone.

Active carriers by state

This is a count of currently active USDOT-registered carriers headquartered in each state, as of September 2026 — not a historical or projected figure. The top 15 states account for 69% of all 2,205,934 active carriers nationally.

Why California and Florida lead, not just Texas

California's lead reflects both its size as a freight destination (the ports of Los Angeles and Long Beach alone move a large share of US containerized imports) and its enormous intrastate trucking market — a huge amount of California freight never crosses a state line. Florida's strong showing reflects a similar dynamic on a different scale: a large, growing state with significant intrastate freight demand and a role as a distribution gateway for the Southeast and Caribbean trade. Texas, Georgia, and New York round out the top five, each combining substantial intrastate demand with a role as a through-freight corridor.

Carrier count isn't the same as fleet size

A state with a lot of active carriers isn't necessarily a state with a lot of trucks — the US trucking industry is overwhelmingly made up of small operations. Nationally, the median active carrier reports a single power unit; see Fleet Size Distribution in US Trucking for the full breakdown. Carrier count by state is best read as a measure of how many independent trucking businesses operate there, not a measure of total hauling capacity — a state with fewer, larger fleets can move more freight than a state with many single-truck operations.

A methodology note on fleet-size totals

We deliberately do not publish a state-by-state sum of reported fleet sizes (total power units) alongside this carrier-count ranking. FMCSA's Company Census File is self-reported on the MCS-150 form, and a small number of records contain fleet-size entries that are obviously data-entry errors — a handful of carriers nationally report fleet sizes in the hundreds of thousands, which is larger than the entire US Class 8 truck population combined. Because these errors are large enough to distort a simple sum (even though they affect well under 0.1% of records), we report carrier counts and per-carrier medians here instead, both of which are far less sensitive to a handful of outliers.

Larger average fleets, where they exist

Among states with at least 5,000 active carriers, a few stand out for a higher median fleet size — meaning their carrier base skews toward multi-truck operations rather than owner-operators, even before accounting for a handful of very large outliers:
