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. No cargo cover filed with FMCSA.

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 Wisconsin average covers 42,237 vehicle and 76,995 driver inspections of all Wisconsin-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
6 violations counted in FMCSA's Safety Measurement System (SMS), 0 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 7 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.

"Share" is this company's mix of violations; the Wisconsin column is the mix across all Wisconsin-based carriers, so you can see which kinds of problems stand out. A high count partly reflects fleet size and how often trucks are inspected.

Questions about SOUTHERN DOOR TRANSPORT LLC
What does SOUTHERN DOOR TRANSPORT LLC's operating authority allow?
MC1204355: Common carrier (may haul regulated property for hire for the general public).
Which information about SOUTHERN DOOR TRANSPORT LLC is old or missing?
Operating authority is the last known status from the FMCSA snapshot of May 14, 2026, not a current check. Insurance filings are from the same May 14, 2026 snapshot. There are too few vehicle inspections in the last 24 months to judge the out-of-service rate. FMCSA has not issued a safety rating, which means no compliance review is on record, not that the carrier is unsafe. The MCS-150 was last updated Jun 23, 2023, so fleet size and contact details may be out of date.
What should I verify before booking SOUTHERN DOOR TRANSPORT LLC?
Confirm the authority and insurance on the Motus record for USDOT 3573225. Call the company back on the phone number on file, (920) 255-3454, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1204355, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
Other companies using (920) 255-3454
A shared number is common for related companies, dispatch services and family businesses. It is not proof of fraud, but it is worth knowing which company you are dealing with.
