Verified Oct 21, 2026 against FMCSA Company Census File (data.transportation.gov)

Riley Brothers Inc (USDOT 1311806, MC-549959) is an active motor carrier based in Stoughton, Massachusetts that FMCSA's census classifies as for-hire and that declares hazardous materials on its MCS-150. Operation: interstate. Operating authority: active for-hire authority (MC). Fleet: 176 power units and 230 drivers (100 with CDLs). Power units count straight trucks as well as tractors, so they can exceed the tractor count. Its MCS-150 of August 19, 2024 reports 1,650,000 miles and gives 2024, the year it was filed, as the mileage year, so the figure is not a full calendar year's total. Cargo classes declared: liquids / gases, general freight, building materials, construction, machinery, large objects, utilities, other cargo (other: Tools & Equipment). It is also classified as a private carrier of its own goods. FMCSA safety rating: conditional, from a compliance review on June 28, 2008, 18 years ago; it reflects that review, not current performance. Registration (MCS-150) last updated August 19, 2024, more than two years ago and past FMCSA's two-year update requirement, so the fleet, driver and cargo figures above may be out of date.

USDOT number: The registration number every interstate (and many intrastate) commercial carrier holds.

MCS-150: The registration form carriers file with FMCSA and must update at least every two years; fleet, drivers, cargo and the hazmat flag on this site come from it, as the carrier declared them.

Safety rating: FMCSA's result after an on-site compliance review: Satisfactory, Conditional or Unsatisfactory. A rating is not refreshed unless FMCSA reviews the carrier again, so many are years old; each profile gives the review date. Most carriers have never been reviewed and are not rated; that is not a bad mark.

Power units: Trucks and tractors that pull or carry freight.

Cargo classes: Self-declared on the MCS-150 from FMCSA's fixed list. Some carriers tick most of the list, so a long list means 'declared', not 'specialises in'; the hazmat flag does not say which hazardous materials.
