Recommendations — what's driving each score
Lighting / lamps violations are the leading contributor to Vehicle Maintenance · high impact
Lighting / lamps 63% (3 OOS) · Brakes 19% (5 OOS) · Tires 5% (1 OOS)
• Walk the lights every pre-trip and carry spare bulbs/fuses; clean lenses and check the trailer plug
• Prioritize the out-of-service items — they carry the heaviest weight
Projected: could improve up to 14 pts in ~12 months if worked down.
Vehicle and 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 Martin County, TX · medium impact
• Review the inspections from Martin County, TX to spot recurring issues
