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.

Brakes violations are the leading contributor to Vehicle Maintenance

High impact

Estimated Vehicle Maintenance percentile of 89% 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 contributing42 violations · 11 OOS (24 mo)

What to do
  • Check brake adjustment and listen for air leaks every pre-trip; put brakes on the PM schedule
  • Fix air-loss and warning-light faults before dispatch — don’t “drive it in”
  • Prioritize the out-of-service items — they carry the heaviest weight

Current trend 50% followed 100% followed 80% line

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

High impact

Vehicle OOS rate is 41.2% vs the 22% national average. Driver OOS rate is 9.4% 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 Middlesex County, CT

Medium impact

17 of 46 violations in the last 12 months (37%) came from inspections in Middlesex County, CT. 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 Middlesex County, CT to spot recurring issues
  • Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

Speeding violations are the leading contributor to Unsafe Driving

Low impact

Estimated Unsafe Driving percentile of 36% is under the 65% line. In decent shape, but here's what's driving it.

Hours-of-Service Compliance needs attention

Low impact

Estimated Hours-of-Service Compliance percentile of 0% is under the 65% 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.
