QUALITY MUFFLERS INCORPORATED: SAN ANTONIO, Texas Trucking Company
QUALITY MUFFLERS INCORPORATED is a small fleet operating out of SAN ANTONIO, Texas with USDOT number 2503288. The company operates 14 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, QUALITY MUFFLERS INCORPORATED has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.
FMCSA Safety Record & Inspection History
QUALITY MUFFLERS INCORPORATED has undergone 32 recorded DOT inspections. The vehicle out-of-service rate is 15.6%, which is below the national average of 20.72%, suggesting solid vehicle maintenance practices. The driver out-of-service rate is 3.1%, within acceptable range compared to the 5.51% national average.
Recorded Violations and Out-of-Service Status
The public FMCSA record for QUALITY MUFFLERS INCORPORATED carries 36 recorded violations, and the most recent inspection on file is dated September 22, 2026. Across 32 recorded inspections, the record carries 2 driver out-of-service violations and 8 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 QUALITY MUFFLERS INCORPORATED: 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
QUALITY MUFFLERS INCORPORATED 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.
QUALITY MUFFLERS INCORPORATED 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: interstate beyond 100 miles (long-haul, 1 drivers); interstate within 100 miles (short-haul, 2 drivers); intrastate beyond 100 miles (2 drivers); intrastate within 100 miles (3 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: 10,000 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: 1 straight truck, 4 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 8 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.
Intrastate driver count: 5. Intrastate drivers may be subject to state-specific CDL endorsement and hours-of-service variances depending on the state.
QUALITY MUFFLERS INCORPORATED's Inspection Fingerprint: Geographic Pattern and Trend
Inspections cluster geographically across Texas (31), Wisconsin (1). The concentration in Texas is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams QUALITY MUFFLERS INCORPORATED's drivers encounter most often at roadside checkpoints.
How QUALITY MUFFLERS INCORPORATED Compares to the National Average
Across the 32 recorded inspections, QUALITY MUFFLERS INCORPORATED's 15.6% vehicle out-of-service rate sits slightly below the FMCSA 2024 national average of 20.72%. The 3.1% driver out-of-service rate sits slightly below the 2024 national average of 5.51%.
