Recommendations

What’s driving each score, what to do about it, and where it could go.

Lighting / lamps violations are the leading contributor to Vehicle Maintenance

High impact

Estimated Vehicle Maintenance percentile of 85% is at/over the 75% 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 37.5% 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

Unsafe Driving needs attention

Low impact

Estimated Unsafe Driving percentile of 0% is under the 60% 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

Hours-of-Service Compliance needs attention

Low impact

Estimated Hours-of-Service Compliance percentile of 0% is under the 60% 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

Driver Fitness needs attention

Low impact

Estimated Driver Fitness percentile of 0% is under the 75% 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

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.
