Findings

A reported fleet far smaller than the vehicles operating under an authority can reflect an out-of-date MCS-150, a large lease-on or owner-operator fleet, or vehicles operating under this authority that the carrier did not register.
- Multiple carriers at this address (Caution): One other active carrier is registered at this physical address. Shared addresses are common for freight offices and registered agents.
- Vehicle maintenance at the FMCSA intervention threshold (Caution): Vehicle maintenance ranks 98 of 100 among similar carriers with recent violations (higher = worse). fleetfax peer estimate, not an official CSA score.
