Machinery Large, Livestock, 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.

Expected crash rate is probably lower 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.

Per truck, fleets like this one are expected to crash about 1.7× as often as the median active fleet of 10–19 trucks.

What's driving the grade
Crash history
betterworse
Lower so far, not yet proven. 1 fatal crash (1 death) on the FMCSA record in 24 months (about 0.5 a year); similar fleets have about 1 a year. Too short a record to be sure, so the grade counts its crash record as about 5% below typical. The grade counts 2 crashes in its 36-month scoring window, recent ones weighted most.
Roadside inspections
betterworse
Better than peers. Violations 0.45×, out-of-service orders 0.54× and unsafe-driving and hours-of-service violations 0.68× the rate expected for its inspections. Together they move its crash estimate -14%: roadside results weigh far less than crash history. It's inspected more often than most fleets its size.

About “In the news”: these links go to third-party news reports that FRED Score matched automatically to FMCSA crash records — same date and place, with a truck or bus involved, and the same number of deaths or, for a crash that released hazardous materials, the release — and checked a second time before showing. A link doesn't mean this motor carrier caused the crash: FMCSA crash reports don't assign fault, and news coverage can be incomplete or wrong. FRED Score doesn't verify or endorse what the articles say.

No other reportable crashes on the FMCSA record.
