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.

Vehicle and driver out-of-service rate exceeds the national average

High impact

Vehicle OOS rate is 33.3% vs the 22% national average. Driver OOS rate is 50% vs the 6.7% 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

Driver Fitness needs attention

Low impact

Estimated Driver Fitness 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

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

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.
