CIS subtotal normalizes 3 publicly-available FMCSA components (Safety Rating + Inspection Pass Rate + OOS Rate) to a 0-100 surface. CSA SMS BASIC percentiles are not published in FMCSA's public Socrata datasets and the SMS portal at ai.fmcsa.dot.gov is not crawlable at scale, so we surface a transparent "Not measured" rather than fabricate a score component. Carriers with a Compliance Review on record may have published BASIC data on the SAFER snapshot for that DOT.
DUNCAN SERVICES INC: RIENZI, Mississippi Trucking Company
DUNCAN SERVICES INC is a small carrier operating out of RIENZI, Mississippi with USDOT number 1342927. The company operates 2 power units and holds a current FMCSA safety rating of Satisfactory. Based on our analysis of federal safety data, DUNCAN SERVICES INC has a FileFlo Carrier Intelligence Score (CIS) of 66/100, classified as Moderate Risk.
FMCSA Safety Record & Inspection History
DUNCAN SERVICES INC has undergone 26 recorded DOT inspections. The vehicle out-of-service rate is 38.5%, 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 15.4%, 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 DUNCAN SERVICES INC carries 50 recorded violations, and the most recent inspection on file is dated 20260327. Across 26 recorded inspections, the record carries 6 driver out-of-service violations and 11 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 66/100 Carrier Intelligence Score Means
A CIS score of 66 places DUNCAN SERVICES INC in the Moderate Risk category. While not in immediate danger of targeted enforcement, there are areas for improvement. Common issues at this level include inconsistent driver qualification file maintenance, lapsed vehicle inspection schedules, or minor CSA BASIC score creep.
Mississippi Trucking Compliance: RIENZI Area Carriers
Motor carriers operating in Mississippi must comply with both federal FMCSA regulations and state-specific transportation requirements. The RIENZI, MS corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in RIENZI should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.
FileFlo helps Mississippi trucking companies automate compliance document tracking across 600+ document types, including CDL medical cards, annual vehicle inspections, drug & alcohol testing records, and driver training certifications.
Authority Type, Hazmat Status, and Operating Profile
DUNCAN SERVICES INC 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.
DUNCAN SERVICES INC 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, 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: 115,263 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
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.
Primary cargo type per MCS-150: Utility Trailers & Signs. Cargo type drives which BASIC categories the carrier is monitored under (Hazmat Compliance applies only to HM-flagged carriers; Cargo-Related Crash applies broadly).
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 2 crash events involving DUNCAN SERVICES INC in the available reporting window. Of these, 0 involved a fatality, 1 involved a reported injury, and 2 resulted in a tow-away. 2 events meet the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
Federal-recordable crashes feed the Crash Indicator BASIC in CSA: carriers above the intervention threshold are 7-10x more likely to be selected for a compliance review than peer carriers below the threshold. Insurance carriers also pull federal-recordable crash counts during quoting; a single recordable crash in a 24-month look-back can drive a 10-20% premium increase for owner-operators and small fleets.
Most recent recorded event: CR-20, MARION, AL on 20201206.
DUNCAN SERVICES INC's Inspection Fingerprint: Geographic Pattern and Trend
Inspections cluster geographically across Tennessee (8), New Mexico (4), Missouri (3). The concentration in Tennessee is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams DUNCAN SERVICES INC's drivers encounter most often at roadside checkpoints.
How DUNCAN SERVICES INC Compares to the National Average
Across the 26 recorded inspections, DUNCAN SERVICES INC's 38.5% vehicle out-of-service rate sits substantially above the FMCSA 2024 national average of 20.72%. The 15.4% driver out-of-service rate sits substantially above the 2024 national average of 5.51%. Vehicle OOS-rate variance is the strongest predictor of Vehicle Maintenance BASIC scores in CSA; driver OOS-rate variance is the strongest predictor of Hours-of-Service Compliance + Driver Fitness BASIC scores.
FMCSA's intervention thresholds (the percentile bands that trigger investigator outreach) are roughly 65th percentile for non-passenger non-hazmat carriers (75th for hazmat, 70th for passenger) on each BASIC. Carriers that consistently sit above the national average across multiple BASICs accumulate intervention risk faster than carriers with mixed performance. A single high BASIC alone rarely triggers enforcement; sustained over-threshold performance does.
