DIETZ & WATSON INC is a mid-size fleet operating out of PHILADELPHIA, Pennsylvania with USDOT number 179189. The company operates 62 power units and holds a current FMCSA safety rating of Satisfactory. Based on our analysis of federal safety data, DIETZ & WATSON INC has a FileFlo Carrier Intelligence Score (CIS) of 59/100, classified as Elevated Risk.
DIETZ & WATSON INC has undergone 50 recorded DOT inspections. The vehicle out-of-service rate is 2.0%, which is below the national average of 20.72%, suggesting solid vehicle maintenance practices.
The public FMCSA record for DIETZ & WATSON INC carries 32 recorded violations, and the most recent inspection on file is dated October 7, 2026. Across 50 recorded inspections, the record carries 0 driver out-of-service violations and 1 vehicle out-of-service violation.
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 DIETZ & WATSON INC: 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. 59 out of 100 falls in FileFlo's Elevated Risk band.
DIETZ & WATSON INC 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.
DIETZ & WATSON INC is classified by FMCSA as an interstate carrier.
The carrier holds an Private Property;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: Corporation.
DIETZ & WATSON INC 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, 51 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: 160,000 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.
Owned equipment per the FMCSA Census filing: 48 straight trucks, 14 tractors, 15 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 51 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.
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 20 crash events involving DIETZ & WATSON INC in the available reporting window. Of these, 0 involved a fatality, 8 involved a reported injury, and 19 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: IS 695 - BALTO BELTWAY (INNER LOOP), TOWSON, MD on January 20, 2026.
Inspections cluster geographically across Pennsylvania (22), Maryland (17), New Jersey (8). The concentration in Pennsylvania is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams DIETZ & WATSON INC's drivers encounter most often at roadside checkpoints.
Across the 50 recorded inspections, DIETZ & WATSON INC's 2.0% vehicle out-of-service rate sits well below the FMCSA 2024 national average of 20.72%. The 0.0% driver out-of-service rate sits materially below the 2024 national average of 5.51%.
