Note: "General Freight" is a catch-all; the actual cargo mix and its risk may differ.

Estimated from the commodity types reported to FMCSA, not from loss history or the true cargo mix.

Mileage Unreliable

MCS-150 annual mileage appears too low for fleet size given observed activity. The per-100k-mile rate benchmarks on this page are excluded; the FRED grade does not use mileage (crash exposure is power-unit-years, violation exposure is inspection counts).

Intrastate operation

Runs within Florida only. Intrastate fleets in Florida are inspected about 1 a year for every 7 trucks; interstate fleets, about 1 a year for every 2 trucks. So this record rests mainly on crash reports, which states file for intrastate trucks too, and few inspections are ordinary here.

No Interstate Operating Authority

This carrier is not authorized for interstate for-hire operations. They may still operate legally as an intrastate for-hire carrier.

Expected crash rate is probably lower than similar fleets (about an 80% chance), but the record is too thin to say by how much.

Similar fleets: intrastate fleets of 20–49 trucks with the same kind of operation, years in business and amount of road activity. Compared using its own crash record and roadside inspections.

What's driving the grade
Crash history
betterworse
Leans better, not yet proven. 0 crashes on the FMCSA record in 24 months; similar fleets have about 0.6 a year.
Roadside inspections
betterworse
Mixed. Out-of-service orders 1.79× and violations 1.68× the rate expected for its inspections, but unsafe-driving and hours-of-service violations 0.64×. Together they move its crash estimate +4%: roadside results weigh far less than crash history. It's inspected more often than most fleets its size.

Worth a closer look

From the FMCSA record. The grade already counts the safety items; insurance filings and links to other motor carriers are not in it.

  • Driver qualification
    7 out-of-service violations against drivers: 5 no valid CDL, 2 English proficiency (Apr 2026 – Sep 2026).
    Ask: driver qualification files and hiring standards.
  • Lights and cargo securement
    Lights are 17 of 43 violations (40%). Light or cargo securement defects led to 7 out-of-service orders.
    Ask: the preventive-maintenance schedule and shop records.
  • Driver out-of-service rate
    21.4% of driver inspections end out of service vs 8.5% for intrastate motor carriers (3 of 14). Across all its inspections, out-of-service orders run 1.79× what's expected for where and how it's inspected.
Strengths
  • No reportable crashes in 24 months.
  • No FMCSA BASIC alerts.
Data flags
  • No active operating authority
    The motor carrier's interstate for-hire authority is revoked or inactive, so it isn't currently cleared to haul interstate for hire.
  • Unreliable reported mileage
    The motor carrier's self-reported annual mileage (MCS-150) looks implausible, so exposure- and mileage-based figures may be distorted.
  • Estimated mileage
    No usable mileage was reported, so exposure was estimated from similar motor carriers. Mileage-based metrics here are approximate.
