Advisory Grade — Outside the Ranked Book

Fleets under 10 power units are graded against their size cohort (pu2_5) for reference, but sit outside the 10+ power-unit underwriting book the FRED rank covers.

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).

Stale MCS-150 Filing

This motor carrier has not updated its MCS-150 in over 3 years. Reported mileage and fleet size may be outdated.

Intrastate operation

Runs within Iowa only. Intrastate fleets in Iowa are inspected about 1 a year for every 11 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.

Not enough record to grade yet.

3 inspections and 1 crash on the FMCSA record in 24 months fit anything from an Excellent fleet to a Poor one.

Similar fleets: intrastate fleets of 2–5 trucks with the same kind of operation, years in business and amount of road activity. Compared using its own crash record and roadside inspections.

Per truck, fleets like this one are expected to crash about 0.3× as often as the median active fleet of 2–5 trucks.

A record this thin can't pin that down: about a 1-in-2 chance it runs at Poor-level crash rates.

Loss runs for the last 3 years, and confirm the fleet is operating at its filed size (3 power units).
What the record shows
Crash history
betterworse
Too little record to tell. 1 injury crash on the FMCSA record in 24 months (about 0.5 a year); similar fleets have under 0.1 a year.
Roadside inspections
betterworse
Better than peers. Unsafe-driving and hours-of-service violations 0.77× the rate expected for its inspections. Together they barely move its crash estimate.

Worth a closer look

From the FMCSA record. The estimate already counts the safety items; insurance filings and links to other motor carriers are context only.

  • Injury crashes
    1 crash with 1 person hurt in 24 months.
    Ask: claim status and driver history for these crashes.
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.
  • Limited inspection history
    Fewer than 5 roadside inspections on record, so there isn't enough data to score this motor carrier with high confidence — the score leans more on peers.
