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 Spokane County, WA

Medium impact

9 of 25 violations in the last 12 months (36%) came from inspections in Spokane County, WA. 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 Spokane County, WA to spot recurring issues
  • Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

False log / RODS violations are the leading contributor to Hours-of-Service Compliance

Low impact

Estimated Hours-of-Service Compliance percentile of 55% is under the 65% line. In decent shape, but here's what's driving it.

What’s contributing5 violations (24 mo)

  • 395.22GPortable ELD not mounted in a fixed position and visible to driver1× · 6%
What to do
  • Audit ELD edits and duty-status annotations weekly; a false log is a high-severity, high-visibility violation
  • Retrain on correct logging and never letting a load pressure a driver into a false entry
Projected estimatecould improve up to 25 pts in ~12 mo

Current trend 50% followed 100% followed 65% line

Controlled Substances/Alcohol needs attention

Low impact

Estimated Controlled Substances/Alcohol percentile of 0% is under the 80% line. In decent shape, but here's what's driving it.

What to do
  • Review recent inspections with violations in this BASIC and take remedial action with drivers/equipment

Brakes violations are the leading contributor to Vehicle Maintenance

Low impact

Estimated Vehicle Maintenance percentile of 64% is under the 80% 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.
