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.
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for FRONK OIL COMPANY 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.
FRONK OIL COMPANY 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.
FRONK OIL COMPANY 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.
Business organization type: Corporation.
FRONK OIL COMPANY 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, 59 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: 5,299,726 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.
Owned equipment per the FMCSA Census filing: 10 straight trucks, 6 tractors, 13 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 59 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: Diesel Gasoline. Cargo type drives which BASIC categories the carrier is monitored under (Hazmat Compliance applies only to HM-flagged carriers; Cargo-Related Crash applies broadly).
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 18 crash events involving FRONK OIL COMPANY INC in the available reporting window. Of these, 1 involved a fatality, 10 involved a reported injury, and 16 resulted in a tow-away. 18 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: 4099 W EASTON PL, TULSA, OK on February 25, 2026.
Inspections cluster geographically across Texas (37), Oklahoma (6), New Mexico (5). The concentration in Texas is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams FRONK OIL COMPANY INC's drivers encounter most often at roadside checkpoints.
Across the 50 recorded inspections, FRONK OIL COMPANY INC's 12.0% vehicle out-of-service rate sits slightly below the FMCSA 2024 national average of 20.72%. The 4.0% driver out-of-service rate sits slightly below the 2024 national average of 5.51%.
