Oregon's 100 Biggest Trucking Fleets (2026)

Nightly aggregation of the FMCSA census puts Oregon at 28,981 active motor carriers running roughly 190,418 power units combined, and about 54% of those carriers are single-truck owner-operators. Average active fleet size works out to 7.2 trucks.

319 new OR carrier registrations appeared in the last 90 days — and 380 registrations carry an FMCSA prior-revocation link, the raw material of chameleon re-registrations.

PORTLAND GENERAL ELECTRIC COMPANY out of TUALATIN tops the OR ranking with 1623 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/750046.
