ROCK-IT NATURAL STONE INC is a small fleet operating out of WISTER, Oklahoma with USDOT number 930899. The company operates 16 power units and has no published FMCSA safety rating (most active carriers are unrated unless they have undergone a compliance review). Based on our analysis of federal safety data, ROCK-IT NATURAL STONE INC has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.

FMCSA Safety Record & Inspection History

ROCK-IT NATURAL STONE INC has undergone 20 recorded DOT inspections. The vehicle out-of-service rate is 30.0%, 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. The driver out-of-service rate is 5%, within acceptable range compared to the 5.51% national average.

Recorded Violations and Out-of-Service Status

The public FMCSA record for ROCK-IT NATURAL STONE INC carries 35 recorded violations, and the most recent inspection on file is dated August 4, 2026. Across 20 recorded inspections, the record carries 1 driver out-of-service violation and 9 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 39/100 Carrier Intelligence Score Means

The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for ROCK-IT NATURAL STONE 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. 39 out of 100 falls in FileFlo's High Risk band.

Oklahoma Trucking Compliance: WISTER Area Carriers

ROCK-IT NATURAL STONE INC 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.

Authority Type, Hazmat Status, and Operating Profile

ROCK-IT NATURAL STONE INC is classified by FMCSA as an interstate carrier.

The carrier holds an 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.

ROCK-IT NATURAL STONE 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, 8 drivers); interstate within 100 miles (short-haul, 8 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: 320,000 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: 8 straight trucks, 6 tractors, 21 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 16 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: Rock, Deleterious. 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 5 crash events involving ROCK-IT NATURAL STONE INC in the available reporting window. Of these, 0 involved a fatality, 1 involved a reported injury, and 5 resulted in a tow-away. 5 events meet the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
