SOUTHERN SUPPLY TRUCKING LLC, DOT #4475793 FMCSA Safety & Compliance Report
5 of your 12 roadside inspections in the last 24 months ended with an out-of-service order, most recently Tennessee on August 27.
Your latest, Nebraska on September 11, had 1 violation, none out of service.
Your MCS-150 lists 9 trucks and 9 drivers.
Between January 28 and March 11 you had 5 inspections and 3 were out of service. Three or more inspections in 90 days with half or more out of service lets FMCSA pull your new-entrant safety audit forward (49 CFR 385.308).
In that audit, a driver who isn't physically qualified, or a disqualified driver, is an automatic failure on a single occurrence, and so are missing logs or annual truck inspections on more than half the records checked (49 CFR 385.321).
SOUTHERN SUPPLY TRUCKING LLC is a small fleet motor carrier based in DAYTON, Tennessee (USDOT #4475793). As of October 22, 2026, it holds a Not Rated FMCSA safety rating and a FileFlo Carrier Intelligence Score of 39/100 (High Risk), based on 12 recent inspection(s) and 20 recorded violation(s) in public FMCSA data.

SOUTHERN SUPPLY TRUCKING LLC: DAYTON, Tennessee Trucking Company
SOUTHERN SUPPLY TRUCKING LLC is a small fleet operating out of DAYTON, Tennessee with USDOT number 4475793. The company operates 9 power units and has no published FMCSA safety rating (most active carriers are unrated unless they have undergone a compliance review). Based on our analysis of federal safety data, SOUTHERN SUPPLY TRUCKING LLC has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.
FMCSA Safety Record & Inspection History
SOUTHERN SUPPLY TRUCKING LLC has undergone 12 recorded DOT inspections. The vehicle out-of-service rate is 33.3%, which is above the national average of 20.72%. This elevated rate indicates potential maintenance or pre-trip inspection deficiencies that could lead to roadside violations. The driver out-of-service rate is 8.3%, above the national average of 5.51%. Common causes include hours-of-service violations, expired medical certificates, and CDL issues.
Recorded Violations and Out-of-Service Status
The public FMCSA record for SOUTHERN SUPPLY TRUCKING LLC carries 20 recorded violations, and the most recent inspection on file is dated September 11, 2026. Across 12 recorded inspections, the record carries 1 driver out-of-service violation and 5 vehicle out-of-service violations.
A recorded violation is what an inspector wrote down at the roadside. It is not a penalty, and it is not an amount owed: FMCSA assesses civil penalties only after a compliance review classifies specific cited violations. The step that changes this record is the document behind each line, so the next move is to see which records an investigator would ask for and which of them exist today.
What a 39/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for SOUTHERN SUPPLY TRUCKING LLC: the safety rating, the inspection pass rate and the out-of-service rate against the national average. It is not an FMCSA score, and FMCSA does not use it to choose carriers for an investigation. 39 out of 100 falls in FileFlo's High Risk band.
Authority Type, Hazmat Status, and Operating Profile
SOUTHERN SUPPLY TRUCKING LLC is classified by FMCSA as an interstate carrier.
The carrier holds an Authorized For Hire classification, meaning it transports cargo or passengers for compensation under FMCSA operating authority and is subject to MC-number requirements at 49 CFR Part 365.
SOUTHERN SUPPLY TRUCKING LLC is not flagged in FMCSA Census as a hazmat carrier (HM indicator: N), so the carrier is not subject to the additional 49 CFR Subchapter C hazmat regulations.
Operational range per MCS-150 filing: interstate beyond 100 miles (long-haul, 9 drivers). The 100-mile boundary matters because drivers operating within a 100-air-mile radius qualify for the short-haul exception under 49 CFR 395.1(e)(1), which removes the requirement to maintain RODS for the day.
Self-reported MCS-150 annual mileage: 1 miles. MCS-150 mileage feeds the FMCSA SafeStat exposure denominator: drastically understated mileage can artificially inflate CSA BASIC percentile scores by reducing the per-mile exposure baseline. Updates are required every 24 months under 49 CFR 390.19.
Fleet Composition and Driver Profile
Owned equipment per the FMCSA Census filing: 9 tractors. Owned-vs-leased equipment matters for compliance documentation, owned trailers require the carrier to retain annual inspection certificates under 49 CFR 396.17, while leased trailers shift that documentation responsibility to the lease agreement.
The carrier reports 9 CDL-holding drivers on file. Each CDL driver must have a current Driver Qualification File (DQF) maintained per 49 CFR 391.51, including a Medical Examiner's Certificate, an annual MVR review, and a record of road-test results.
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 1 crash event involving SOUTHERN SUPPLY TRUCKING LLC in the available reporting window. Of these, 0 involved a fatality, 1 involved a reported injury, and 1 resulted in a tow-away. 1 event meets the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
Most recent recorded event: STATE ROAD 91 (RONALD REAGAN TURNPIKE, WILDWOOD, FL on June 19, 2026.
