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 about the same as similar fleets.

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.

What's driving the grade
Crash history
betterworse
Lower so far, not yet proven. 2 crashes on the FMCSA record in 24 months (about 1 a year), including 1 with injuries; similar fleets have about 1.6 a year. Too short a record to be sure, so the grade counts its crash record as about 12% above typical. The grade counts 5 crashes in its 36-month scoring window, recent ones weighted most.
Roadside inspections
betterworse
Better than peers. Unsafe-driving and hours-of-service violations 0.32× and out-of-service orders 0.67× the rate expected for its inspections. Together they move its crash estimate -15%. It's inspected more often than most fleets its size.

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.
    Ask: claim status and driver history for these crashes.
  • Vehicle out-of-service rate
    46.7% of vehicle inspections end out of service vs 22.3% nationally (7 of 15), but across all its inspections out-of-service orders are 0.67× what's expected for where and how it's inspected, the measure the grade uses.
Strengths
  • Driver out-of-service rate 0.0% vs 6.7% national.
  • No FMCSA BASIC alerts.
  • 82% of inspections found no violations.
Data flags
  • Dangerous driving: 2
