Verified Oct 30, 2026 against FMCSA Company Census File (data.transportation.gov)

Roy Miller Freight Lines LLC (USDOT 12663, MC-120391) is an active motor carrier based in Anaheim, California 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: 280 power units and 86 drivers (82 with CDLs). Power units count straight trucks as well as tractors, so they can exceed the tractor count. It reported 3,500,000 miles for 2023 on its MCS-150. Cargo classes declared: chemicals, liquids / gases, general freight, intermodal containers, building materials, construction, machinery, large objects, metal: sheets, coils, rolls, agricultural / farm supplies, grain, feed, hay, paper products. It is also classified as a private carrier of its own goods. FMCSA has not issued it a safety rating (no compliance review on record). In the last 24 months it had 209 roadside inspections, 19 of them (9.1%) with an out-of-service order; 12 hazmat inspections; 3 reportable crashes (0 deaths, 1 injury); a crash on record does not by itself mean the carrier caused it. Registration (MCS-150) last updated October 26, 2026.

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.

Reportable crash: A crash involving the carrier's vehicle with a death, an injury treated away from the scene or a vehicle towed away. FMCSA records it whoever was at fault.

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.
