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.

Driver qualification / CDL / medical violations are the leading contributor to Driver Fitness

High impact

Estimated Driver Fitness percentile of 96% is at/over the 80% 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.

What’s contributing6 violations · 6 OOS (24 mo)

What to do
  • Run a credential-expiration tracker; keep DQ files complete and the medical card on the driver

Driver out-of-service rate exceeds the national average

High impact

Driver OOS rate is 25% 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

A high share of violations are occurring in Columbia County, GA

Medium impact

10 of 37 violations in the last 12 months (27%) came from inspections in Columbia County, GA. 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 Columbia County, GA to spot recurring issues
  • Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

Following / lane / reckless violations are the leading contributor to Unsafe Driving

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

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