Recommendations — what's driving each score
Driver qualification / CDL / medical violations are the leading contributor to Driver Fitness · high impact
Driver qualification / CDL / medical 100% (6 OOS)
• Run a credential-expiration tracker; keep DQ files complete and the medical card on the driver
• Prioritize the out-of-service items — they carry the heaviest weight
Projected: could improve up to 26 pts in ~12 months if worked down.
Lighting / lamps violations are the leading contributor to Vehicle Maintenance · high impact
Lighting / lamps 52% · Brakes 20% · Other 17%
• Walk the lights every pre-trip and carry spare bulbs/fuses; clean lenses and check the trailer plug
Projected: could improve up to 43 pts in ~12 months if worked down.
Driver out-of-service rate exceeds the national average · high impact
• 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
A high share of violations are occurring in Columbia County, GA · medium impact
• 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 · low impact
Following / lane / reckless 43% · Seat belt 40% · Speeding 17%
