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.

Expected crash rate is probably higher than similar fleets (about a 70% chance), but the record is too thin to say by how much.

Similar fleets: for-hire 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.

What's driving the grade
Crash history
betterworse
Leans worse, not yet proven. 3 crashes on the FMCSA record in 24 months (about 1.5 a year), including 1 with injuries; similar fleets have about 0.4 a year.
Roadside inspections
betterworse
Mixed. Unsafe-driving and hours-of-service violations 2.27× the rate expected for its inspections, but out-of-service orders 0.68× and violations 0.80×. Together they move its crash estimate +4%: roadside results weigh far less than crash history.

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.

  • Injury crashes
    1 crash with 1 person hurt in 24 months.
