Independent estimate — not an official FMCSA or CSA score. Highest estimated percentile band: Low.

This percentile is an independent estimate produced by ranking FMCSA's publicly published BASIC measure within a safety-event peer group. FMCSA does not publish percentiles for property carriers; this figure is HaulReport's reconstruction and may differ from any internal FMCSA value. Bands describe percentile ranges among peers, not safety judgments. It is provided for general informational purposes only; it is not a consumer report and may not be used for any purpose governed by the Fair Credit Reporting Act (including credit, insurance, employment, or tenant screening), and it is not a safety rating, a fitness determination, legal advice, or a recommendation to do business with any carrier. Always verify against official FMCSA sources before relying on it.
