Arizona's 100 Biggest Trucking Fleets (2026)

Nightly aggregation of the FMCSA census puts Arizona at 32,171 active motor carriers running roughly 212,005 power units combined, and about 51% of those carriers are single-truck owner-operators. Average active fleet size works out to 7.6 trucks.

603 new AZ carrier registrations appeared in the last 90 days — and 427 registrations carry an FMCSA prior-revocation link, the raw material of chameleon re-registrations.

PG TRUCKING LLC out of PHOENIX tops the AZ ranking with 92901 power units on its latest MCS-150. Its complete vetting workup — risk flags, score breakdown, insurance filings, and record timeline — is at https://mclookup.com/carrier/2855794.
