The Tucson carrier base in numbers
| Carriers registered locally | 2,700 |
|---|---|
| Single-truck operators | 1,584 (59%) |
| Fleets of 2 to 10 power units | 943 (35%) |
| Fleets above 50 power units | 29 |
| Carriers flagged for hazardous materials | 182 (7%) |
| Registrations added since 2025 | 341 (13%) |
| Last MCS-150 filed more than 24 months ago | 1,384 (51%) |
Where Tucson differs from the national picture
Filing currency is the standout number here. 1,384 carriers, 51% 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 59% 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.
New registrations are running close to the national rate: 341 carriers here, 13% of the base, registered from 2025 onward against 12% nationally. Some carriers first registered in 2025 or later may still be within FMCSA’s New Entrant Safety Assurance Program, depending on their registration date and current status.
What Tucson carriers actually haul
The commodities most often declared by carriers registered in Tucson are general freight (510), construction (217), passengers (172), general freight; construction (95), household goods (57). On operating classification, 1,906 are recorded as interstate and 719 as intrastate, which decides whether the federal hours-of-service and driver qualification rules apply in full or whether the state variation governs.
Federal and Arizona requirements

A change made in one system may also require a separate filing or update in the other.

DOT compliance questions for Tucson
Which DOT records matter for border-linked distribution, aerospace, mining supply, construction and regional freight in Tucson?
A Tucson file should connect the carrier record, authority and insurance scope, driver qualification and testing status, HOS evidence, inspection and maintenance files, shipment documents and dispatch record for the actual movement.
Does a short route around Tucson automatically count as intrastate work?
No. Mileage around Tucson does not decide the character of commerce. Review where the shipment originated, its intended destination, the carrier relationship and whether the movement forms part of a continuous interstate trip.
How should a Tucson carrier document activity at the Port of Tucson inland intermodal facility?
Keep the relevant Tucson gate, access, interchange or customer timestamp with the dispatch, equipment, duty-time and shipment record. The evidence should identify who controlled the vehicle and how the carrier handled a defect or delay.
What maintenance evidence is useful for Tucson operations?
Inspect tires, brakes and cooling systems before remote routes and require full records from mobile repair vendors. For a Tucson unit, retain the complaint, equipment identity, work performed, responsible vendor and return-to-service date.
When should a Tucson carrier arrange a compliance review?
A Tucson review is useful before new entrant activity, after fleet or route growth, when inspection patterns worsen, after a major customer changes the operating model, or whenever management cannot retrieve complete evidence consistently.
