Satisfactory
Provisional: the filed fleet isn't backed up by the roadside record (only 6 of the 40 filed power units were seen at a roadside inspection in 24 months), so the grade can't lean on this motor carrier's own history until the fleet size is confirmed.
FRED Score 74.7 / 100
The FRED Score (0–100, higher is better) compares this motor carrier's expected crash rate with that of similar fleets. It is an analytical opinion, not an FMCSA safety rating.

These records come from FMCSA's Safety Measurement System, Oct 2024 – Jul 2026; the grade counts crashes Oct 1, 2023 – Sep 30, 2026 and inspections Nov 1, 2024 – Oct 31, 2026 from FMCSA's weekly files, so counts can differ.
