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 about 8% lower than similar fleets.

Similar fleets: interstate fleets of about 8 trucks with the same kind of operation, years in business and amount of road activity. Compared using its own crash record and roadside inspections.

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.

  • Little roadside history
    Only 4 inspections in 24 months for 8 power units, where interstate fleets of 6–9 trucks in South Dakota average about 9; the record says little either way.
    Ask: confirm the fleet is operating at the filed size (the MCS-150 was last updated Jun 2026).
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.
