FOX UNDERGROUND SERVICES LLC, DOT #4442147 FMCSA Safety & Compliance Report
Your drivers have been put out of service on every inspection on your record: Colorado on Oct. 28, 2025, Feb. 4, June 25 and Aug. 17.
Every one included a driver qualification violation.
Your MCS-150 lists 12 trucks and 7 drivers.
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).
FOX UNDERGROUND SERVICES LLC is a small fleet motor carrier based in AURORA, Colorado (USDOT #4442147). As of October 28, 2026, it holds a Not Rated FMCSA safety rating and a FileFlo Carrier Intelligence Score of 39/100 (High Risk), based on 4 recent inspection(s) and 19 recorded violation(s) in public FMCSA data.

FOX UNDERGROUND SERVICES LLC: AURORA, Colorado Trucking Company
FOX UNDERGROUND SERVICES LLC is a small fleet operating out of AURORA, Colorado with USDOT number 4442147. The company operates 12 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, FOX UNDERGROUND SERVICES LLC has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.
FMCSA Safety Record & Inspection History
FOX UNDERGROUND SERVICES LLC has undergone 4 recorded DOT inspections. The vehicle out-of-service rate is 75.0%, 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 100%, 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 FOX UNDERGROUND SERVICES LLC carries 19 recorded violations, and the most recent inspection on file is dated August 17, 2026. Across 4 recorded inspections, the record carries 6 driver out-of-service violations and 4 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 FOX UNDERGROUND SERVICES 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
FOX UNDERGROUND SERVICES LLC is classified by FMCSA as an intrastate non-hazmat 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.
FOX UNDERGROUND SERVICES LLC is flagged in FMCSA Census as a hazardous materials carrier (HM indicator: Y). Hazmat carriers are subject to additional regulations under 49 CFR Subchapter C, including HM-126 reporting, HM-232 security planning, and the Hazmat Cargo Tank Annual Inspection requirement (49 CFR 180.407). Hazmat violations carry their own, higher penalty schedule, separate from the general FMCSA schedule.
Operational range per MCS-150 filing: intrastate within 100 miles (7 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
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.
Intrastate driver count: 7. Intrastate drivers may be subject to state-specific CDL endorsement and hours-of-service variances depending on the state.
Primary cargo type per MCS-150: Other. Cargo type drives which BASIC categories the carrier is monitored under (Hazmat Compliance applies only to HM-flagged carriers; Cargo-Related Crash applies broadly).
How FOX UNDERGROUND SERVICES LLC Compares to the National Average
Across the 4 recorded inspections, FOX UNDERGROUND SERVICES LLC's 75.0% vehicle out-of-service rate sits substantially above the FMCSA 2024 national average of 20.72%. The 100.0% driver out-of-service rate sits substantially above the 2024 national average of 5.51%.
