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.

Mileage Unreliable

MCS-150 annual mileage appears implausibly high for fleet size. The per-100k-mile rate benchmarks on this page are excluded; the FRED grade does not use mileage (crash exposure is power-unit-years, violation exposure is inspection counts).

Expected crash rate is about 47% higher than similar fleets.

Similar fleets: for-hire fleets of 200–499 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
Worse than peers. 31 crashes on the FMCSA record in 24 months (about 16 a year), including 1 fatal (1 death) and 10 with injuries; similar fleets have about 11 a year. The grade counts 51 crashes in its 36-month scoring window, recent ones weighted most.
Roadside inspections
betterworse
Better than peers. Violations 0.77× the rate expected for its inspections. Together they move its crash estimate -5%. 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.

  • Fatal crash
    1 crash with 1 fatality in 24 months (most recent Oct 7, 2024).
    Ask: the accident register and loss runs for these crashes.
  • Injury crashes
    10 crashes with 13 people hurt in 24 months.
    Ask: claim status and driver history for these crashes.
  • Drivers put out of service
    6 out-of-service violations against drivers: 4 hours of service, 2 no valid CDL (Dec 2024 – Sep 2025).
    Ask: driver supervision and dispatch practices.
  • Brakes and tires
    Brakes are 128 of 427 violations (30%). Brake or tire defects led to 103 out-of-service orders.
    Ask: the preventive-maintenance schedule and shop records.
  • Vehicle out-of-service rate
    34.1% of vehicle inspections end out of service vs 22.3% nationally (112 of 328), but across all its inspections out-of-service orders are 0.97× what's expected for where and how it's inspected, the measure the grade uses.
Strengths
  • Driver out-of-service rate 1.1% vs 6.7% national.
  • No FMCSA BASIC alerts.
Data flags
  • Dangerous driving: 6
  • Excessive speeding: 16
  • Unreliable reported mileage
    The motor carrier's self-reported annual mileage (MCS-150) looks implausible, so exposure- and mileage-based figures may be distorted.
  • Estimated mileage
    No usable mileage was reported, so exposure was estimated from similar motor carriers. Mileage-based metrics here are approximate.
