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.

Recommendations

What’s driving each score, what to do about it, and where it could go.

A high share of violations are occurring in Los Angeles County, CA

Medium impact

92 of 184 violations in the last 12 months (50%) came from inspections in Los Angeles County, CA. That can mean tougher enforcement there or simply more of your miles run through it — either way it's worth a look.

What to do
  • Review the inspections from Los Angeles County, CA to spot recurring issues
  • Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

Other violations are the leading contributor to Unsafe Driving

Shared VINs come from FMCSA roadside-inspection records — a vehicle inspected under more than one carrier, often a fleet transfer or trailer interchange. Other links come from the FMCSA census. Shared identifiers are common and often legitimate — treat these as leads to investigate, not proof of wrongdoing.
