How are these Louisville trucking companies ranked?
Carriers are ranked by total power units (the count of self-propelled commercial vehicles in their fleet) as reported to FMCSA on Form MCS-150. Power units include tractors, straight trucks, and buses — but not trailers. We apply a quality filter requiring a driver-to-truck ratio between 0.3 and 5.0 to exclude obviously-erroneous self-reports.
How is the MC Look Up trust score calculated?
The 0–100 trust score is computed from FMCSA data across five layers: (1) carrier type classification, (2) binary gates for hard rejections (revoked authority, no insurance, out-of-service), (3) confidence-weighted safety, crash, insurance, and authority signals, (4) chameleon-carrier cross-reference detection, and (5) decision floors that cap dangerously high ratings for carriers with red flags. Scores map to APPROVE (75–100), REVIEW (40–74), or REJECT (0–39).
