The Duluth carrier base in numbers
| Carriers registered locally | 792 |
|---|---|
| Single-truck operators | 452 (57%) |
| Fleets of 2 to 10 power units | 308 (39%) |
| Fleets above 50 power units | 6 |
| Carriers flagged for hazardous materials | 70 (9%) |
| Registrations added since 2025 | 107 (14%) |
| Last MCS-150 filed more than 24 months ago | 386 (49%) |
Where Duluth differs from the national picture
Filing currency is the standout number here. 386 carriers, 49% of the local base, last filed an MCS-150 more than two years ago, well above the national picture of 38%. The biennial update is required on the applicable filing cycle even when nothing has changed, and missing a required update can affect the carrier’s USDOT record.
The fleet mix runs below the national shape, with 57% single-truck operators against 64% nationally. At that size the owner may handle much of the compliance administration personally. Owner-operators who are subject to Part 382 generally participate in a compliant random-testing consortium or similar third-party program.
Hazardous materials carry more weight here than they do nationally: 70 carriers (9%) hold a hazmat flag against 7% across the country. That adds placarding, shipping papers, security plans and endorsement checks to the standard file.

DOT compliance questions for Duluth
What should a Duluth DOT compliance review cover first?
Begin with the carrier identity and operating scope, then verify driver qualification and testing status, available hours, vehicle condition, registration, authority, shipment records and the evidence created on a real Duluth trip.
Is freight that stays near Duluth always intrastate?
No. Distance from Duluth does not decide the character of commerce. Review shipment origin, intended destination, the transportation agreement and whether the local leg is part of a continuous interstate movement.
Which records matter around the Port of Duluth-Superior and Twin Ports industrial terminals?
Retain the relevant access, gate, scale, interchange or customer record with dispatch, driver, equipment, duty-time and shipment evidence. The file should identify who controlled the vehicle and how any delay or defect was handled.
How should a Duluth carrier document outside maintenance?
Review brakes, tires, suspension, lighting and cold-weather systems for heavy port and northern routes. The work order should identify the unit, reported condition, inspection or repair performed, responsible vendor and return-to-service decision.
When is a compliance review useful for a Duluth fleet?
Review before new entrant activity, fleet or route growth, a new cargo type, worsening roadside patterns, a major contract change or any point when management cannot retrieve complete records consistently.
