Green means the FMCSA record shows it. It does not confirm who you are talking to, or that a policy covers your specific load.

Not a live check. FMCSA has not published a Motus record for this carrier, so authority and insurance show the last known status from May 14, 2026. Confirm on Motus ↗ before booking.

Insurance on file

Liability (BI&PD) pays for injury and damage to other people and property; it does not cover the freight. Cargo insurance covers the freight. FMCSA only requires cargo filings from household goods carriers and freight forwarders, so most carriers file none: ask for a cargo certificate that fits your load. Cargo cover filed: amount not published.

How these rates are calculated

Period: Oct 19, 2024 – Oct 19, 2026. Vehicle rate = vehicle inspections with a vehicle out-of-service order ÷ vehicle inspections (levels 1, 2, 5 and 6). Driver rate uses levels 1, 2, 3 and 6. The South Carolina average covers 18,704 vehicle and 40,858 driver inspections of all South Carolina-based carriers in this period. It mixes every type of operation, so compare with care; rates based on a handful of inspections say little. FMCSA's own SMS measures are weighted differently: SMS profile ↗ · SAFER snapshot ↗

Violations in FMCSA's SMS last 24 months

42 violations counted in FMCSA's Safety Measurement System (SMS), 9 of them serious enough to put the driver or vehicle out of service.

Why is this different from the 75 violations above?

The inspections section's number counts every violation written on the inspection reports in our Oct 19, 2024 – Oct 19, 2026 window. The SMS count comes from FMCSA's own monthly SMS snapshot, which uses its own 24-month window and only the violations it scores. Both are FMCSA figures; they measure different things.

MC342834: Common carrier (may haul regulated property for hire for the general public); Contract carrier (may haul regulated property for hire under continuing contracts with specific shippers).

Which information about SUPERIOR TRANSPORTATION INC is old or missing?

What should I verify before booking SUPERIOR TRANSPORTATION INC?

Confirm the authority and insurance on the Motus record for USDOT 760583. Call the company back on the phone number on file, (843) 740-1840, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC342834, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
