Key facts

Fleet size	100–499 power units Power units, banded. source, unchanged since Oct 25, 2026
FMCSA safety rating	Satisfactory Satisfactory, Conditional or Unsatisfactory after an FMCSA compliance review; most carriers have never had one and are not rated. source, unchanged since Oct 25, 2026
Rating age	Rating 5–10 years old How old the FMCSA safety rating is. A rating reflects one compliance review on that date, not current performance; old ratings say little about the carrier today. source, unchanged since Oct 25, 2026
Registration update overdue	No Yes means the MCS-150 was last updated more than two years ago, past FMCSA's two-year update requirement; fleet, driver and cargo figures may then be out of date. source, unchanged since Oct 25, 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.
