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 a 90% 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.

Per truck, fleets like this one are expected to crash about 0.6× as often as the median active fleet of 20–49 trucks.

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 0.7 a year.
Roadside inspections
betterworse
Better than peers. Out-of-service orders 0.31×, violations 0.43× and unsafe-driving and hours-of-service violations 0.64× 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.

  • Nothing on the FMCSA record stands out.
Strengths
  • No reportable crashes in 24 months.
  • Driver out-of-service rate 0.0% vs 6.7% national.
  • 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.

Checking FMCSA…

No MC, FF or MX docket on FMCSA's registration for this motor carrier, so there are no insurance filings to show. FMCSA collects filings only from registered for-hire authorities; other motor carriers keep proof of insurance (MCS-90) at their place of business.

FMCSA filings only, not a policy audit. Not part of the FRED grade. Wrong or out of date?
