Carrier Intelligence Score

52/100 Elevated Risk

Category	Score	Max
Safety Rating	10	30
Inspection Pass Rate	15	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.

Recorded Violations and Out-of-Service Status

The public FMCSA record for DIAMOND B CONSTRUCTION CO LLC carries 16 recorded violations, and the most recent inspection on file is dated 20261007. Across 15 recorded inspections, the record carries 1 driver out-of-service violation and 2 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 52/100 Carrier Intelligence Score Means

A CIS score of 52 places DIAMOND B CONSTRUCTION CO LLC 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.

Louisiana Trucking Compliance: ALEXANDRIA Area Carriers

Motor carriers operating in Louisiana must comply with both federal FMCSA regulations and state-specific transportation requirements. The ALEXANDRIA, LA corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in ALEXANDRIA should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.

DIAMOND B CONSTRUCTION CO LLC falls under the Western Service Center for FMCSA field-office oversight (region code 06). Service-center territory drives which FMCSA Investigator team would conduct a new-entrant audit or compliance review if one is triggered for this carrier.

FileFlo helps Louisiana 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

DIAMOND B CONSTRUCTION CO LLC 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.

Business organization type: Corporation.

DIAMOND B CONSTRUCTION CO LLC 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 within 100 miles (short-haul, 14 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: 175,605 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: 9 straight trucks, 6 tractors. 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.

Primary cargo type per MCS-150: Equipment, Diesel Fuel. 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 17 crash events involving DIAMOND B CONSTRUCTION CO LLC in the available reporting window. Of these, 0 involved a fatality, 7 involved a reported injury, and 16 resulted in a tow-away. 17 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: N 3RD, ALEXANDRIA, LA on 20260522.

How DIAMOND B CONSTRUCTION CO LLC Compares to the National Average

Across the 15 recorded inspections, DIAMOND B CONSTRUCTION CO LLC's 13.3% vehicle out-of-service rate sits slightly below the FMCSA 2024 national average of 20.72%. The 6.7% driver out-of-service rate sits moderately above 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.
