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).

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 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 under a tenth as often as the median active fleet of 10–19 trucks.

What's driving the grade
Crash history

Leans better, not yet proven. 0 crashes on the FMCSA record in 24 months; similar fleets have about 0.1 a year.
Roadside inspections
betterworse
Better than peers. Out-of-service orders 0.36× and unsafe-driving and hours-of-service violations 0.37× the rate expected for its inspections. Together they move its crash estimate -19%.

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.

  • Lights and steering & suspension
    Lights are 23 of 46 violations (50%). Light or steering & suspension defects led to 1 out-of-service order.
    Ask: the preventive-maintenance schedule and shop records.
  • Cross-border operation
    13 inspections on Mexico-plated units.
    Ask: operating radius and Mexico lanes.
Strengths
  • No reportable crashes in 24 months.
  • Vehicle out-of-service rate 5.9% vs 22.3% national; driver 0.0% vs 6.7%.
  • 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.
  • Mexico-domiciled motor carrier
    Domiciled in Mexico — cross-border operating rules and inspection patterns differ from US-based motor carriers.
