Source: FMCSA Licensing & Insurance (L&I), public data. This shows the carrier’s federal insurance filings (BMC-91X liability, BMC-34 cargo) — the federally-required minimums on file for operating authority — not the carrier’s full commercial policy (its actual auto combined-single-limit, general liability, cargo, or workers’ comp, which appear on the carrier’s ACORD certificate of insurance). Always confirm current coverage with a COI from the carrier’s agent before making a vetting decision.

Shared identifiers are common and often legitimate — treat these as leads to investigate, not proof of wrongdoing.
