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 49/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for MAINE BIO-FUEL 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. 49 out of 100 falls in FileFlo's Elevated Risk band.
Authority Type, Hazmat Status, and Operating Profile
MAINE BIO-FUEL 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.
MAINE BIO-FUEL 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, 4 drivers); interstate within 100 miles (short-haul, 4 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: 65,000 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: 4 straight trucks. 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.
Primary cargo type per MCS-150: Vegetable Oil. 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 4 crash events involving MAINE BIO-FUEL INC in the available reporting window. Of these, 0 involved a fatality, 0 involved a reported injury, and 4 resulted in a tow-away. 4 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: RTE 93 S X 46, METHUEN, MA on November 6, 2024.
