Phoenix is the registered base for 7,551 motor carriers, running 415,395 power units and 78,799 drivers between them. It is a fleet market rather than an owner-operator one, with 163 carriers running more than 50 power units, so compliance work here is usually a program rather than a one-off filing.

The Phoenix carrier base in numbers
| Carriers registered locally | 7,551 |
|---|---|
| Single-truck operators | 4,659 (62%) |
| Fleets of 2 to 10 power units | 2,343 (31%) |
| Fleets above 50 power units | 163 |
| Carriers flagged for hazardous materials | 537 (7%) |
| Registrations added since 2025 | 1,038 (14%) |
| Last MCS-150 filed more than 24 months ago | 3,372 (45%) |
What the local carrier data shows
Filing currency is the standout number here. 3,372 carriers, 45% of the local base, last filed an MCS-150 more than two years ago, 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.
New registrations are running close to the national rate: 1,038 carriers here, 14% 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.
The fleet mix runs close to the national shape, with 62% 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.
Freight and routes around Phoenix

DOT compliance questions for Phoenix
Which DOT records matter for large-scale distribution, construction, food, parcel and manufacturing work in Phoenix?
A Phoenix 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 Phoenix automatically count as intrastate work?
No. Mileage around Phoenix 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 Phoenix carrier document activity at Phoenix regional logistics parks and air-cargo facilities?
Keep the relevant Phoenix 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 Phoenix operations?
Use heat-season inspection intervals for tires, cooling systems and batteries and retain detailed return-to-service evidence. For a Phoenix unit, retain the complaint, equipment identity, work performed, responsible vendor and return-to-service date.
When should a Phoenix carrier arrange a compliance review?
A Phoenix 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.
