Verified Oct 30, 2026 against FMCSA Company Census File (data.transportation.gov)

Southern Pipe & Supply Company Inc (USDOT 79183, MC-781961), doing business as Southern Trucking, is an active motor carrier based in Meridian, Mississippi that FMCSA's census classifies as for-hire and that declares hazardous materials on its MCS-150. Operation: interstate. Operating authority: active for-hire authority (MC). Fleet: 269 power units and 362 drivers (50 with CDLs). Power units count straight trucks as well as tractors, so they can exceed the tractor count. It reported 10,750,000 miles for 2025 on its MCS-150. Cargo classes declared: chemicals, general freight, building materials, construction, machinery, large objects, other cargo (other: Plumbing Supplies). FMCSA safety rating: satisfactory, from a compliance review on November 6, 2006, 20 years ago; it reflects that review, not current performance. In the last 24 months it had 206 roadside inspections, 28 of them (13.6%) with an out-of-service order; 18 reportable crashes (0 deaths, 9 injuries); a crash on record does not by itself mean the carrier caused it. Registration (MCS-150) last updated March 20, 2026.

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 over 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updated more than two years ago, past FMCSA's two-year update requirement; fleet, driver and cargo figures may then be out of date.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.
