BLUE DIAMOND BUILDERS TRUST is a small fleet operating out of FOXBORO, Massachusetts with USDOT number 3185564.

Based on our analysis of federal safety data, BLUE DIAMOND BUILDERS TRUST has a FileFlo Carrier Intelligence Score (CIS) of 77/100, classified as Moderate Risk.
FMCSA Safety Record & Inspection History
BLUE DIAMOND BUILDERS TRUST has undergone 5 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.
Recorded Violations and Out-of-Service Status
The public FMCSA record for BLUE DIAMOND BUILDERS TRUST carries 24 recorded violations, and the most recent inspection on file is dated October 13, 2026. Across 5 recorded inspections, the record carries 0 driver out-of-service violations and 3 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 77/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for BLUE DIAMOND BUILDERS TRUST: 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. 77 out of 100 falls in FileFlo's Moderate Risk band.
Authority Type, Hazmat Status, and Operating Profile
BLUE DIAMOND BUILDERS TRUST is classified by FMCSA as an intrastate non-hazmat 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.
BLUE DIAMOND BUILDERS TRUST 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, 1 drivers); intrastate beyond 100 miles (7 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: 1,000 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: 12 straight trucks, 2 tractors, 6 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 4 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: 7. 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 1 crash event involving BLUE DIAMOND BUILDERS TRUST in the available reporting window. Of these, 0 involved a fatality, 0 involved a reported injury, and 1 resulted in a tow-away. 1 event meets 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: 1107 SOUTH ST, WRENTHAM, MA on July 31, 2026.
How BLUE DIAMOND BUILDERS TRUST Compares to the National Average
