The SaferGrade score is a records-based composite of public FMCSA data, comparing this carrier's records against national baselines. It is observational only and is not a safety-fitness determination — FMCSA cautions that SMS data alone cannot be used to draw safety-fitness conclusions, and the underlying data has known limitations.
