Recommendations

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

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

High impact

Estimated Hours-of-Service Compliance percentile of 86% is at/over the 60% 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 contributing4 violations · 3 OOS (24 mo)
False log / RODS3 OOS4 viol100%

  • 395.8A-ELDELD - No record of duty status (ELD Required)1× · 40%
  • 395.22H4Driver failed to maintain supply of blank drivers records of duty status graph-grids1× · 6%
What to do
  • Audit ELD edits and duty-status annotations weekly; a false log is a high-severity, high-visibility violation
  • Retrain on correct logging and never letting a load pressure a driver into a false entry
  • Prioritize the out-of-service items — they carry the heaviest weight

Lighting / lamps violations are the leading contributor to Vehicle Maintenance

High impact

Estimated Vehicle Maintenance percentile of 88% 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 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 11.5% 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 Hopkins County, TX

Medium impact

11 of 23 violations in the last 12 months (48%) came from inspections in Hopkins 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 Hopkins County, TX to spot recurring issues
  • Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical

Seat belt violations are the leading contributor to Unsafe Driving

Estimated Unsafe Driving percentile of 9% is under the 60% line. In decent shape, but here's what's driving it.

Driver Fitness needs attention

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

Estimated Controlled Substances/Alcohol 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

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.
