Safety Measurement System (SMS)

FMCSA's official per-BASIC roadside-performance measures over the trailing 24 months, computed from the 7 inspections below. A measure of 0 means no recorded violations in that BASIC — not necessarily a strong safety record on a small sample. FMCSA does not publish peer-group percentiles for property carriers, so the underlying measures — not percentile rankings — are shown; Hazmat Compliance and Crash Indicator are not published. Based on fewer than 11 inspections — treat these measures as a weak signal.
