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.

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

High impact

Estimated Unsafe Driving percentile of 72% is at/over the 65% 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 35.7% 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

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

Medium impact

Estimated Hours-of-Service Compliance percentile of 60% is close to the 65% intervention line — worth getting ahead of before it crosses.

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

Medium impact

16 of 31 violations in the last 12 months (52%) came from inspections in Kleberg 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 Kleberg County, TX to spot recurring issues
  • Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

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.
