DIAMOND PLUS TRANSPORTATION INC: WALNUT, California Trucking Company
DIAMOND PLUS TRANSPORTATION INC is a small fleet operating out of WALNUT, California with USDOT number 2574313. 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, DIAMOND PLUS TRANSPORTATION INC has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.
FMCSA Safety Record & Inspection History
DIAMOND PLUS TRANSPORTATION INC has undergone 50 recorded DOT inspections. The vehicle out-of-service rate is 20.0%, which is below the national average of 20.72%, suggesting solid vehicle maintenance practices. The driver out-of-service rate is 8%, 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 DIAMOND PLUS TRANSPORTATION INC carries 86 recorded violations, and the most recent inspection on file is dated October 3, 2026. Across 50 recorded inspections, the record carries 4 driver out-of-service violations and 18 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 DIAMOND PLUS TRANSPORTATION 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. 39 out of 100 falls in FileFlo's High Risk band.
Authority Type, Hazmat Status, and Operating Profile
DIAMOND PLUS TRANSPORTATION 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.
DIAMOND PLUS TRANSPORTATION 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, 11 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: 1,866,508 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: 14 tractors, 28 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 14 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: 3. Intrastate drivers may be subject to state-specific CDL endorsement and hours-of-service variances depending on the state.
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 5 crash events involving DIAMOND PLUS TRANSPORTATION INC in the available reporting window.

Most recent recorded event: I-75 SB NEAR EXIT #310, Not Reported, GA on September 9, 2026.
