Top 100 Delaware Trucking Fleets by Power Units (2026)

Nightly aggregation of the FMCSA census puts Delaware at 5,062 active motor carriers running roughly 19,857 power units combined, and about 45% of those carriers are single-truck owner-operators. Average active fleet size works out to 4.7 trucks.

80 new DE carrier registrations appeared in the last 90 days — and 141 registrations carry an FMCSA prior-revocation link, the raw material of chameleon re-registrations.

MATLACK INC out of WILMINGTON tops the DE ranking with 881 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/113527.
