DUVALL BUS SERVICE LLC has undergone 44 recorded DOT inspections.
The public FMCSA record for DUVALL BUS SERVICE LLC carries 4 recorded violations, and the most recent inspection on file is dated August 6, 2026. Across 44 recorded inspections, the record carries 0 driver out-of-service violations and 0 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.
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for DUVALL BUS SERVICE 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. 100 out of 100 falls in FileFlo's Low Risk band.
DUVALL BUS SERVICE LLC falls under the Eastern Service Center for FMCSA field-office oversight (region code 03). Service-center territory drives which FMCSA Investigator team would conduct a new-entrant audit or compliance review if one is triggered for this carrier.
DUVALL BUS SERVICE LLC is classified by FMCSA as an interstate carrier.
The carrier holds an Private Passenger, Business;Private Passenger, Non-Business;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.
Business organization type: Individual.
DUVALL BUS SERVICE 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, 6 drivers); interstate within 100 miles (short-haul, 35 drivers); intrastate within 100 miles (14 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: 863,330 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.
The carrier reports 55 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: 14. Intrastate drivers may be subject to state-specific CDL endorsement and hours-of-service variances depending on the state.
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 20 crash events involving DUVALL BUS SERVICE LLC in the available reporting window. Of these, 0 involved a fatality, 11 involved a reported injury, and 16 resulted in a tow-away. 20 events meet 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: ROUTE 3043 S, SOUTH COATESVILLE BOROUGH, PA on December 13, 2023.
Inspections cluster geographically across Pennsylvania (33), US (6), New Jersey (5). The concentration in Pennsylvania is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams DUVALL BUS SERVICE LLC's drivers encounter most often at roadside checkpoints.
