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.

English language violations are the leading contributor to Driver Fitness

High impact

Estimated Driver Fitness percentile of 99% is at/over the 75% intervention line. Carriers with a BASIC in alert are prioritized for enforcement (warning letters, audits) and inspected more often — which tends to generate still more violations.

Vehicle out-of-service rate exceeds the national average

High impact

Vehicle OOS rate is 23.6% vs the 22% national average. Carriers above the national OOS average draw more enforcement attention (audits, roadside stops) and can see higher insurance premiums.

What to do
  • Review recent inspections with out-of-service violations and fix the root causes with equipment and drivers
  • Run a preventative-maintenance program; periodically inspect tires, brakes and lights
  • Reinforce thorough pre-trip and post-trip inspections; retrain where needed

A high share of violations are occurring in Cameron County, TX

Medium impact

105 of 128 violations in the last 12 months (82%) came from inspections in Cameron County, TX. 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 Cameron County, TX to spot recurring issues
  • Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

Drugs / alcohol violations are the leading contributor to Controlled Substances/Alcohol

Low impact

Estimated Controlled Substances/Alcohol percentile of 33% is under the 75% line. In decent shape, but here's what's driving it.

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.
