Based on our analysis of federal safety data, COOK & SON LLC has a FileFlo Carrier Intelligence Score (CIS) of 88/100, classified as Low Risk.
FMCSA Safety Record & Inspection History
COOK & SON LLC has undergone 14 recorded DOT inspections. The vehicle out-of-service rate is 7.1%, which is below the national average of 20.72%, suggesting solid vehicle maintenance practices.
Recorded Violations and Out-of-Service Status
The public FMCSA record for COOK & SON LLC carries 18 recorded violations, and the most recent inspection on file is dated June 2, 2026. Across 14 recorded inspections, the record carries 0 driver out-of-service violations and 1 vehicle out-of-service violation.
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 88/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for COOK & SON LLC: 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. 88 out of 100 falls in FileFlo's Low Risk band.
Authority Type, Hazmat Status, and Operating Profile
COOK & SON LLC is classified by FMCSA as an interstate carrier.
The carrier holds an Private Property;Authorized For Hire;Exempt 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.
COOK & SON LLC is not flagged in FMCSA Census as a hazmat carrier (HM indicator: N), so the carrier is not subject to the additional 49 CFR Subchapter C hazmat regulations.
Operational range per MCS-150 filing: interstate beyond 100 miles (long-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.
Fleet Composition and Driver Profile
Owned equipment per the FMCSA Census filing: 5 straight trucks, 8 tractors, 8 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 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.

Of these, 1 involved a fatality, 0 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).
Most recent recorded event: I-22, RURAL MARION, AL on March 9, 2026.
