Trucking companies in Illinois: Chicagoland's small carriers, downstate's bigger fleets and how to check one

This report is for shippers and plant logistics teams choosing an Illinois carrier, drivers weighing employers, and B2B sellers whose customers are trucking companies: insurers, fuel and parking providers, dealers, factoring firms and software vendors. It covers the whole state; the Chicago trucking report goes deeper on the metro.

Illinois trucking in one table

US Census Bureau County Business Patterns (CBP) 2023, NAICS 484 (Truck Transportation), state of Illinois:

Only California has more trucking establishments; Texas and California have more trucking jobs. The gap comes from size: Illinois establishments average 5.8 employees, against 13.5 in neighboring Wisconsin.

Two markets: Chicagoland and everywhere else

Summing the county file for the nine Illinois counties in the Chicago metro (Cook, DuPage, Will, Lake, Kane, McHenry, Kendall, DeKalb and Grundy) gives 12,356 establishments and 61,386 employees. The rest of Illinois has 2,664 establishments (including two the Census Bureau doesn't assign to a county) and 25,272 employees.

Cook County alone has 6,896 establishments and 35,576 employees. Downstate, fewer establishments carry more people each: Rock Island and McLean counties average more than 20 employees per site, four times the Cook County figure.

What kind of trucking Illinois does

Long-distance truckload is 46.4% of establishments at 4.4 employees each: the owner-operator with a tractor and an employee or two. Less-than-truckload (LTL) is the opposite: 691 terminals with 23.2% of all Illinois trucking jobs.

The Census Bureau doesn't publish the 1,000-or-more cell for Illinois; the published classes already add up to the 15,020 total, so it is zero by subtraction. In broader bands: 14,238 establishments have 1 to 19 employees, 627 have 20 to 99, and 155 have 100 or more.

What CBP counts: establishments (locations) with paid employees, not companies, so a carrier with terminals in Joliet and Decatur counts twice. It leaves out owner-operators with no employees, and private fleets (a manufacturer's own trucks) are counted in their owner's industry. Employment is for one pay period in March 2023.

The federal register: 56,041 Illinois carriers

FMCSA's Company Census File lists every entity with a USDOT number, as the carriers themselves report it on form MCS-150. Carriers must update that form every 24 months or have the USDOT number deactivated (49 CFR 390.19). Figures below are active registrations with an Illinois physical address in the file dated 29 October 2026, excluding bus operators.

That's 3.7 registrations for every Census establishment, because the register includes owner-operators, farm and contractor fleets and carriers that rarely run. Another 6,562 for-hire records report no power units at all, and 24 report more than 50 with almost no drivers: typing errors, not fleets. New for-hire registrations that are still active rose from 3,739 in 2025 to 4,213 in 2026 through 29 October, which is the stream of new carriers that insurers and factoring firms chase.

The largest for-hire fleets registered in Illinois

Ranked by power units, these are active for-hire records with an Illinois address, updated since October 2024, with drivers equal to at least half the power units. We left out waste and recycling haulers.

Several are fleets of distributors that hold for-hire authority; US Foods' two records add up to 6,084 power units. Downstate names (Mt Sterling, Edwardsville, East St. Louis, Rock Island) match the bigger-establishment counties in the Census data. No SEC-listed company in the trucking SIC codes (4210 to 4231) has an Illinois business address on EDGAR, so revenue for these carriers isn't public.

How to check an Illinois carrier

1. Pull the SAFER snapshot. Search the USDOT or MC number in FMCSA's Company Snapshot for operation type, power units, drivers, inspections, out-of-service rates and crashes.
2. Check the MCS-150 date in the same record. If it's more than two years old, the carrier is overdue and its number can be deactivated.
3. Confirm insurance against the load. The federal minimum for for-hire general freight is $750,000, rising to $1,000,000 for most hazardous materials and $5,000,000 for hazardous substances in bulk tanks (49 CFR 387.9). Ask for a certificate naming you.
4. For moves that start and end in Illinois, confirm the carrier holds an ICC Public Carrier Certificate, required for for-hire intrastate transport of property other than household goods, with insurance kept on file at the commission. The ICC's entity search looks up carriers by name, ILCC number or USDOT number.
5. Ask where the trucks park. IDOT reports that interstate rest-area truck spaces run at 94% utilization on average and that public facilities supply only about 15% of the state's truck parking, so a carrier with its own yard is less likely to lose hours hunting for a space.

The freight behind the count

IDOT's 2023 State Freight Plan puts about 1.6 billion tons of freight, worth $2.5 trillion, flowing into, out of and through Illinois in 2019, and ranks Illinois the third busiest freight state by value and fourth by tonnage, citing FHWA. Rail and barge do the long haul for much of it; trucks do the first and last miles, which is why so many Illinois carriers are small local operations tied to a terminal or an elevator.

Prospecting Illinois trucking companies

The register gives you the dates that make outreach timely: a new USDOT number, a jump in power units, or an MCS-150 that is coming due. For the people behind each fleet, see how to find decision makers.

Illustrative example. The company, prices and win rate are invented; the carrier counts are from FMCSA's October 2026 file.

Prairie Yard (prairieyard.example) runs fenced truck and trailer parking off I-80. It targets for-hire carriers registered in Will, Kendall, Grundy and LaSalle counties with 6 to 50 power units and an MCS-150 updated since October 2024: 553 carriers running 9,099 power units between them. If 5% take four spaces each at $250 a month, that's 28 carriers, 112 spaces and $336,000 a year. The opener is the shortage the carriers already feel at the rest areas. Bebop can build that list from a plain description and research each carrier before the first call.

Hi [first name], it's [your name] from Prairie Yard. I saw [company] runs about [number] trucks out of [city].

We have fenced, lit parking a few minutes off I-80 at [exit], with spaces open this month for tractors and trailers.

If your drivers lose time looking for a spot at night, call me back at [number] and I'll hold four spaces for a week so you can try it.
