Trucking companies in California: the largest and most fragmented market in the US

This report is for shippers, growers and importers looking for a California carrier, drivers comparing employers, and B2B sellers whose customers are trucking companies: emissions testers and repair shops, insurers, factoring firms, dealers and software vendors.

Two counts of California trucking companies

The Census figure counts establishments, not companies, and leaves out owner-operators with no employees. FMCSA's Company Census File catches those owner-operators, which is why it's more than three times as large. It lists 189,048 active for-hire registrations with a California address and at least one truck, but only 79,090 updated their self-reported filing in the two years to 30 October 2026, and we count those. We also dropped 55 large fleets reporting fewer drivers than a tenth of their power units, usually typing errors.

A state of one-truck carriers

In Census bands, 22,538 establishments have 1 to 19 employees, 1,324 have 20 to 99 and 213 have 100 or more. In the register, 67% of current for-hire carriers run one power unit, against 59% nationally. Ranking the Census state file ourselves, California is second to Texas on trucking employment but 47th of 51 on average establishment size.

What California trucking does

Average pay is our calculation from payroll and employees. California is unusual in having more local general freight establishments than long-distance truckload ones: 40% of the total. Specialized local freight (dump, bulk, tank and agricultural hauling) pays best, at about $73,500.

The register shows the same two economies. Of the 79,090 current for-hire carriers, 17,262 (22%) list fresh produce and 11,270 (14%) intermodal containers, against 14% and 8% of current for-hire registrations nationally. Cargo types are self-reported by carriers, and FMCSA's open-data file doesn't always match a carrier's own SAFER record, so treat these shares as indicative. The Port of Los Angeles alone handled 10,239,318 TEUs in 2025, and each of those containers leaves the terminal by truck or train.

Where California's carriers are

Fresno and Kern counties have far more registered carriers than paid-employee establishments: the Central Valley is owner-operator country. Across eight Valley counties (San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings, Tulare and Kern) the register lists 20,820 current for-hire carriers. San Bernardino County runs bigger sites, 9.2 employees each against 5.9 in Los Angeles County.

Congestion is part of the cost. The American Transportation Research Institute's 2026 list of the 100 worst US truck bottlenecks includes eight California locations, led by I-10 at I-15 in Ontario at #12, SR 60 at SR 57 in Los Angeles at #16 and I-710 at I-105 at #25, where peak-hour truck speeds average 28.3 mph.

The largest for-hire fleets in the register

Current for-hire filings with a California address, ranked by power units as reported. We left out DHL Express's air-express fleet, a waste hauler, a tree-care company, a roadside-assistance fleet and one 2024 registration reporting 1,500 tractors but 65,000 miles a year.

No California-based carrier comes near the size of the national fleets headquartered in Arizona or Tennessee. Two SEC-listed companies in trucking and warehousing codes are based in the state, both small: Armlogi Holding Corp. of Walnut (Nasdaq: BTOC), a warehousing and logistics provider whose 10-K reports $185.8 million of revenue for the year to 30 June 2026, and Elite Express Holding Inc. of Laguna Hills (Nasdaq: ETS), a last-mile package carrier that reported $2,665,948 of revenue for the year to 30 November 2025.

California rules a carrier must meet

The Department of Motor Vehicles requires a Motor Carrier Permit for:

• anyone paid to transport property, regardless of vehicle size, type or weight
• operators of a commercial vehicle rated at 10,001 pounds or more, for hire or private
• truck and trailer combinations over 40 feet, any vehicle carrying hazardous materials, and any vehicle needing a commercial license

A carrier needs a CA number from the California Highway Patrol before applying, and must file proof of liability cover of $300,000 to $5,000,000 depending on vehicle and cargo. On top of that, the California Air Resources Board says Clean Truck Check requirements are in effect for subject vehicles, including vehicles registered outside California when they operate in the state: owners report their vehicles, pay an annual compliance fee and submit passing emissions tests.

1. Check the USDOT record in FMCSA's SAFER Company Snapshot, and authority and insurance in Licensing and Insurance for interstate work.
2. Ask for the CA number and Motor Carrier Permit for any load that stays in California.
3. Ask whether every truck is compliant with Clean Truck Check, since a noncompliant truck is a delivery risk.
4. For port work, confirm the carrier's terminal access, chassis source and appointment process.

Selling to California trucking companies

Regulation is the strongest trigger in this state: every new CARB or DMV deadline sends carriers looking for help at once. For a list-building method, see how to build a prospect list.

Illustrative example. The tester and its prices are invented; the counts are FMCSA register data.

Valley Smoke Check (valleysmoke.example) runs mobile emissions tests at a carrier's yard and files the results. Its list is the 1,704 current for-hire carriers in the eight Central Valley counties with 6 to 100 power units: enough trucks that driving each one to a test station costs a day, too few for an in-house program. With one contact each (owner or fleet manager) and a 6% reply rate, that's 102 conversations; if one in four books a yard visit, 25 fleets, and each comes back for the next test cycle. Bebop can find carriers matching that description and research each one first.

Subject: Clean Truck Check for [company]'s [number] trucks

Hi [first name],

[Company] runs [number] power units out of [city]. Taking each one to a test station is a lost day per truck.

We test every truck at your yard in one visit, file the results with CARB and remind you before the next cycle.

Can I hold a morning for your yard the week of [date]?

[Your name]
