Recorded Violations and Out-of-Service Status

The public FMCSA record for MASS GREEN INSULATION INC carries 41 recorded violations, and the most recent inspection on file is dated September 29, 2026. Across 30 recorded inspections, the record carries 8 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.

What a 59/100 Carrier Intelligence Score Means

The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for MASS GREEN INSULATION 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.

Authority Type, Hazmat Status, and Operating Profile

MASS GREEN INSULATION INC is classified by FMCSA as an interstate carrier.

The carrier is classified as Private Property, meaning it transports its own goods incidental to its primary business, exempt from MC-number authority but still subject to safety regulations under 49 CFR Part 390.

MASS GREEN INSULATION 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, 30 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: 250,000 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: 32 straight trucks, 2 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.

Primary cargo type per MCS-150: Insulation Products. Cargo type drives which BASIC categories the carrier is monitored under (Hazmat Compliance applies only to HM-flagged carriers; Cargo-Related Crash applies broadly).
