Trucking companies in Minnesota: 3,240 employers, MnDOT's carrier rules and the seasons that shape the work

This report is for Minnesota shippers, co-ops and manufacturers choosing a carrier, drivers comparing fleets, and B2B sellers whose customers are trucking companies: equipment dealers, insurers, routing and compliance software vendors, fuel suppliers and repair shops. For the metro alone, see the Minneapolis-St. Paul trucking report.

Minnesota trucking by the numbers

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

Local general and specialized local carriers are more than half of all establishments (1,725) but average about five employees: the grain, aggregate, milk and delivery haulers that work within a day's drive of home.

Beyond the metro

The 13 Minnesota counties in the Twin Cities metro have 1,454 trucking establishments. The other 74 counties have 1,786 (including two the Census Bureau doesn't assign to a county), so the outstate market is the bigger one by count.

Stearns County is the largest trucking county outside the metro, and FMCSA's register shows why: two of the state's largest fleets have St. Cloud addresses. In the north, the Duluth Seaway Port Authority describes Duluth-Superior as the Great Lakes' largest port by tonnage, moving more than 35 million tons a year of iron ore, coal, limestone, grain, cement and salt.

The two largest classes aren't published. The 100-or-more band (48) is the published total less the smaller bands, which leaves three establishments with 500 or more employees. In broader bands: 2,929 have 1 to 19 employees and 263 have 20 to 99.

CBP counts establishments with paid employees, not companies; it leaves out owner-operators with no payroll, and a co-op's or contractor's own trucks are counted in farming or construction.

Rules for Minnesota carriers

MnDOT's Office of Freight and Commercial Vehicle Operations regulates carriers that work inside the state. For a for-hire carrier of property (other than household goods):

1. Register the business with the Minnesota Secretary of State first.
2. Get a USDOT number. MnDOT says carriers providing transportation within Minnesota must have one; only interstate numbers carry a federal fee.
3. File a registration statement and get a Certificate of Registration. Until it arrives, MnDOT says, the carrier may not legally operate.
4. Have the insurer file Form E with at least $100,000 for bodily injury to one person, $300,000 for all persons in one accident and $50,000 for property damage. The name and address must match the application.
5. Complete the Initial Motor Carrier Contact (IMCC) safety education within 90 days of the certificate, or MnDOT cancels it.

Interstate for-hire carriers also need federal authority and at least $750,000 of liability cover for general freight (49 CFR 387.9), and every carrier must update its MCS-150 every 24 months (49 CFR 390.19).

The seasons: load limits in 2026

MnDOT adjusts legal weights on trunk highways twice a year: winter load increases while the ground is frozen, and spring load restrictions while it thaws. The 2026 dates by zone:

The day counts are our arithmetic from MnDOT's dates. MnDOT gives at least three days' notice of each change, and county roads and city streets set their own limits. For a carrier hauling grain, aggregate or logs, those weeks decide when trucks run full and when they sit.

What the federal register shows

FMCSA's Company Census File (29 October 2026) has 76,365 active USDOT registrations with a Minnesota physical address, 23.6 for each Census establishment. Without bus operators, 30,783 are for-hire and 39,135 run private fleets only.

MnDOT requires USDOT numbers of carriers that work only within Minnesota, so intrastate carriers show up in the federal file: 65.1% of for-hire records are intrastate only. Carriers report these figures themselves, and 35 for-hire records claim more than 50 power units with almost no drivers, which are typing errors. Newly registered for-hire carriers still active rose from 1,744 in 2025 to 2,027 in 2026 through 29 October.

The largest fleets outside the Twin Cities

Statewide, the largest current for-hire records are Stan Koch & Sons Trucking (Golden Valley, 968 power units), ATS Specialized (St. Cloud, 916) and TA Dedicated (Eagan, 838). Outside the 13 metro counties, the largest active for-hire records updated since October 2024, with drivers at least half the power units, are:

ATS's two records add up to 1,234 power units. Some records belong to companies outside trucking, such as Fastenal, whose fleet is registered for hire; they buy trucks and fleet services all the same. No SEC-listed company in the trucking SIC codes is headquartered in Minnesota.

Prospecting Minnesota trucking companies

The cleanest trigger in the state is the new-carrier clock: a carrier with a fresh USDOT number and certificate has 90 days to complete IMCC and is buying insurance, compliance help and equipment at the same time. For list building, see how to build a prospect list.

Illustrative example. The product, price and conversion rate are invented; the carrier count is from FMCSA's October 2026 file.

Frostline Routing (frostline.example) sells route planning that knows MnDOT's restricted routes and county posting dates. It targets for-hire carriers outside the metro with 6 to 50 power units and a current MCS-150: 795 carriers running 10,513 power units. If 6% subscribe at $25 per power unit a month, that's 48 carriers with about 630 units and $189,000 a year. Outreach starts in January, before the restriction dates are announced. Bebop can build the list and research each carrier's lanes before the first message.

Subject: Spring restrictions and [company]'s routes

Hi [first name],

Last spring your zone ran restricted weights for [number] days. For a fleet of [number] trucks hauling [commodity] out of [town], that's a lot of light loads.

We map MnDOT and county restrictions onto your daily routes so drivers take the roads that are open at full weight.

Can I show you last spring's routes for your area, rerun with restrictions, on a 15-minute call in [month]?

[Your name]
