45/100 Elevated Risk
| Category | Score | Max |
|---|---|---|
| Safety Rating | 10 | 30 |
| Inspection Pass Rate | 10 | 20 |
| Out-of-Service Rate (vs FMCSA national avg) | 9 | 15 |
| CSA BASIC percentiles | Not measured | n/a |
CIS subtotal normalizes 3 publicly-available FMCSA components (Safety Rating + Inspection Pass Rate + OOS Rate) to a 0-100 surface. CSA SMS BASIC percentiles are not published in FMCSA's public Socrata datasets and the SMS portal at ai.fmcsa.dot.gov is not crawlable at scale, so we surface a transparent "Not measured" rather than fabricate a score component. Carriers with a Compliance Review on record may have published BASIC data on the SAFER snapshot for that DOT.

FMCSA Safety Record & Inspection History
3B AUTO INC has undergone 11 recorded DOT inspections. The vehicle out-of-service rate is 36.4%, which is above the national average of 20.72%. This elevated rate indicates potential maintenance or pre-trip inspection deficiencies that could lead to roadside violations.
Recorded Violations and Out-of-Service Status
The public FMCSA record for 3B AUTO INC carries 34 recorded violations, and the most recent inspection on file is dated 20260811. Across 11 recorded inspections, the record carries 0 driver out-of-service violations and 6 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 45/100 Carrier Intelligence Score Means
A CIS score of 45 places 3B AUTO INC in the Elevated Risk category. Carriers at this level are more likely to be selected for compliance reviews and roadside inspections. Immediate attention to driver qualification files, hours-of-service records, and vehicle maintenance logs is recommended.
Massachusetts Trucking Compliance: WORCESTER Area Carriers
Motor carriers operating in Massachusetts must comply with both federal FMCSA regulations and state-specific transportation requirements. The WORCESTER, MA corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in WORCESTER should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.
FileFlo helps Massachusetts trucking companies automate compliance document tracking across 600+ document types, including CDL medical cards, annual vehicle inspections, drug & alcohol testing records, and driver training certifications.
Authority Type, Hazmat Status, and Operating Profile
3B AUTO 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.
3B AUTO 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, 9 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 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.
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 2 crash events involving 3B AUTO INC in the available reporting window. Of these, 0 involved a fatality, 1 involved a reported injury, and 2 resulted in a tow-away. 2 events meet the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
Federal-recordable crashes feed the Crash Indicator BASIC in CSA: carriers above the intervention threshold are 7-10x more likely to be selected for a compliance review than peer carriers below the threshold. Insurance carriers also pull federal-recordable crash counts during quoting; a single recordable crash in a 24-month look-back can drive a 10-20% premium increase for owner-operators and small fleets.
Most recent recorded event: 800 W CUMMINGS PARK, WOBURN, MA on 20220406.
3B AUTO INC's Inspection Fingerprint: Geographic Pattern and Trend
Inspections cluster geographically across Rhode Island (10), Massachusetts (1). The concentration in Rhode Island is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams 3B AUTO INC's drivers encounter most often at roadside checkpoints.
How 3B AUTO INC Compares to the National Average
Across the 11 recorded inspections, 3B AUTO INC's 36.4% vehicle out-of-service rate sits substantially above 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%. Vehicle OOS-rate variance is the strongest predictor of Vehicle Maintenance BASIC scores in CSA; driver OOS-rate variance is the strongest predictor of Hours-of-Service Compliance + Driver Fitness BASIC scores.
FMCSA's intervention thresholds (the percentile bands that trigger investigator outreach) are roughly 65th percentile for non-passenger non-hazmat carriers (75th for hazmat, 70th for passenger) on each BASIC. Carriers that consistently sit above the national average across multiple BASICs accumulate intervention risk faster than carriers with mixed performance. A single high BASIC alone rarely triggers enforcement; sustained over-threshold performance does.
