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.

Upside Withheld

Its risk relativity (0.67× similar fleets) would put it in Strong; this rule holds it at Satisfactory:

  • Held one band lower (interim): the filed fleet isn't corroborated roadside — see Exposure Unverified below

The downside is never capped.

Exposure Unverified

The expected crashes behind this grade assume the filed fleet of 36 power units is real, but the roadside record corroborates little of it — 8 units seen in 24 months, 0.24 inspections per filed unit-year. The grade's relativity to class is unchanged; its confidence tier is cut to reflect the unverified exposure, and until the fleet is confirmed an Excellent grade shows as Strong and a Strong as Satisfactory. Verify the fleet size before relying on the crash expectation.

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).

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: interstate 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 0.8 a year.
Roadside inspections
betterworse
Mixed. Out-of-service orders 1.51× and violations 1.35× the rate expected for its inspections, but unsafe-driving and hours-of-service violations 0.52×. Together they barely move its crash estimate: roadside results weigh far less than crash history.

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
    4 out-of-service violations against drivers: 3 no valid CDL, 1 English proficiency (Sep 2024 – Sep 2025).
    Ask: driver qualification files and hiring standards.
  • Brakes and lights
    Brakes are 12 of 24 violations (50%). Brake or light defects led to 9 out-of-service orders.
    Ask: the preventive-maintenance schedule and shop records.
  • Vehicle out-of-service rate
    46.2% of vehicle inspections end out of service vs 22.3% nationally (6 of 13). Across all its inspections, out-of-service orders run 1.51× what's expected for where and how it's inspected.
  • Filed fleet not seen on the road
    Only 8 of the 36 filed power units were seen at a roadside inspection in 24 months (19 inspections in all). The crash expectation behind the grade assumes all 36 are running. Its grade is held one band lower until the fleet is confirmed.
    Ask: how many trucks are actually operating, with the vehicle schedule (the MCS-150 was last updated Aug 2026).
Strengths
  • No reportable crashes in 24 months.
  • No FMCSA BASIC alerts.
Data flags
  • 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.
