3 J UNDERGROUND LLC, DOT #4486654 FMCSA Safety & Compliance Report
8 to 12 trucks: $900 a month for 3 months, then $1,500.
Your trucks or drivers have been put out of service on every inspection since June 7: Tennessee on June 7 and Aug. 24.
Your MCS-150 lists 8 trucks and 8 drivers.
Between December 9, 2025 and December 29, 2025 you had 3 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).
3 J UNDERGROUND LLC is a small fleet motor carrier based in BYHALIA, Mississippi (USDOT #4486654). As of November 5, 2026, it holds a Not Rated FMCSA safety rating and a FileFlo Carrier Intelligence Score of 39/100 (High Risk), based on 7 recent inspection(s) and 26 recorded violation(s) in public FMCSA data.

3 J UNDERGROUND LLC: BYHALIA, Mississippi Trucking Company
3 J UNDERGROUND LLC is a small fleet operating out of BYHALIA, Mississippi with USDOT number 4486654. The company operates 8 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, 3 J UNDERGROUND LLC has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.
FMCSA Safety Record & Inspection History
3 J UNDERGROUND LLC has undergone 7 recorded DOT inspections. The vehicle out-of-service rate is 57.1%, 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 57.1%, 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 3 J UNDERGROUND LLC carries 26 recorded violations, and the most recent inspection on file is dated August 24, 2026. Across 7 recorded inspections, the record carries 8 driver out-of-service violations 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 3 J UNDERGROUND 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
3 J UNDERGROUND LLC is classified by FMCSA as an interstate carrier.
The carrier is classified as Private Property, meaning it transports its own goods incidental to its primary business, exempt from MC-number authority but still subject to safety regulations under 49 CFR Part 390.
3 J UNDERGROUND 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 within 100 miles (short-haul, 8 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.
Fleet Composition and Driver Profile
Owned equipment per the FMCSA Census filing: 8 straight trucks, 8 trailers. 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 1 CDL-holding driver 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.
3 J UNDERGROUND LLC's Inspection Fingerprint: Geographic Pattern and Trend
Inspections cluster geographically across Tennessee (5), Mississippi (2). The concentration in Tennessee is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams 3 J UNDERGROUND LLC's drivers encounter most often at roadside checkpoints.
How 3 J UNDERGROUND LLC Compares to the National Average
Across the 7 recorded inspections, 3 J UNDERGROUND LLC's 57.1% vehicle out-of-service rate sits substantially above the FMCSA 2024 national average of 20.72%. The 57.1% driver out-of-service rate sits substantially above the 2024 national average of 5.51%.
