CAROLINA BLOCK OF LAKE CITY: LAKE CITY, South Carolina Trucking Company
CAROLINA BLOCK OF LAKE CITY is a mid-size fleet operating out of LAKE CITY, South Carolina with USDOT number 3988820. The company operates 25 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, CAROLINA BLOCK OF LAKE CITY has a FileFlo Carrier Intelligence Score (CIS) of 59/100, classified as Elevated Risk.
FMCSA Safety Record & Inspection History
CAROLINA BLOCK OF LAKE CITY has undergone 50 recorded DOT inspections. The vehicle out-of-service rate is 14.0%, 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 CAROLINA BLOCK OF LAKE CITY carries 46 recorded violations, and the most recent inspection on file is dated October 28, 2026. Across 50 recorded inspections, the record carries 0 driver out-of-service violations 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 59/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for CAROLINA BLOCK OF LAKE CITY: 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. 59 out of 100 falls in FileFlo's Elevated Risk band.
Authority Type, Hazmat Status, and Operating Profile
CAROLINA BLOCK OF LAKE CITY 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.
CAROLINA BLOCK OF LAKE CITY 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, 29 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: 1,800,903 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: 25 tractors, 29 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 29 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: Cement Blocks. 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 9 crash events involving CAROLINA BLOCK OF LAKE CITY in the available reporting window. Of these, 0 involved a fatality, 5 involved a reported injury, and 9 resulted in a tow-away. 9 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: 214, BOLTON, NC on September 10, 2026.
