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.

Not enough record to grade yet.

42 inspections and 4 crashes on the FMCSA record in 24 months fit anything from an Excellent fleet to a Poor one. It leans worse than similar fleets (about a 60% chance), but not by enough to grade.

Similar fleets: interstate 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 the record shows
Crash history
betterworse
Leans worse, not yet proven. 4 crashes on the FMCSA record in 24 months (about 2 a year), including 2 with injuries; similar fleets have about 0.6 a year.
Roadside inspections
betterworse
Mixed. Out-of-service orders 1.64× the rate expected for its inspections, but unsafe-driving and hours-of-service violations 0.53×. Together they barely move its crash estimate: roadside results weigh far less than crash history. It's inspected more often than most fleets its size.

Worth a closer look

From the FMCSA record. The estimate already counts the safety items; insurance filings and links to other motor carriers are context only.

  • Injury crashes
    2 crashes with 2 people hurt in 24 months.
    Ask: claim status and driver history for these crashes.
  • Lapse in liability filings
    No liability filing on FMCSA's file since Apr 2, 2026 (42 days through May 14, 2026) while the authority required one. Not in the grade.
    Ask: what covered the fleet during the gap.
  • Lights and cargo securement
    Lights are 15 of 57 violations (26%). Light or cargo securement defects led to 11 out-of-service orders.
    Ask: the preventive-maintenance schedule and shop records.
  • Vehicle out-of-service rate
    54.2% of vehicle inspections end out of service vs 22.3% nationally (13 of 24). Across all its inspections, out-of-service orders run 1.64× what's expected for where and how it's inspected.
Strengths
  • Driver out-of-service rate 2.4% vs 6.7% national.
  • No FMCSA BASIC alerts.
Data flags
  • Dangerous driving: 1
