General Freight

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.

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.

Expected crash rate is about 12% higher than similar fleets.

Similar fleets: intrastate fleets of about 15 trucks with the same kind of operation, years in business and amount of road activity. Compared using its own crash record and roadside inspections.

Leaning Marginal. Its estimate (1.12× similar fleets) is in the Marginal range, but the record isn't strong enough to be 60% sure it is above the Marginal line (1.06×), so the grade stays Satisfactory.

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.

    1 crash with 1 person hurt in 24 months.
    Ask: claim status and driver history for these crashes.
  • Brakes and tires
    Brakes are 30 of 58 violations (52%). Brake or tire defects led to 12 out-of-service orders.
    Ask: the preventive-maintenance schedule and shop records.
  • Hazmat violations
    6 hazmat violations, 1 out of service.
  • New since the grade was set
    1 out-of-service inspection after Jul 31, 2026. Not in the grade yet.

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 Wrong or out of date?
