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 California only. Intrastate fleets in California are inspected about 1 a year for every 4 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.

Not enough record to grade yet.

4 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 10–19 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 0.5× as often as the median active fleet of 10–19 trucks.

A record this thin can't pin that down: about a 1-in-5 chance it runs at Poor-level crash rates.

What the record shows
Crash history
betterworse
Higher so far, not yet proven. 1 crash on the FMCSA record in 24 months (about 0.5 a year); similar fleets have about 0.2 a year. Too few crashes to be sure, so the grade counts its crash record as about 5% above typical.
Roadside inspections
betterworse
Mixed. Violations 1.48× the rate expected for its inspections, but unsafe-driving and hours-of-service violations 0.71×. 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.

  • Nothing on the FMCSA record stands out.
Strengths
  • 1 crash in 24 months. No injuries, no fatalities.
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.
  • 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.
