Brakes 45% (2 OOS) · Tires 15% (4 OOS) · Lighting / lamps 13% (1 OOS)
• 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”
Projected: could improve up to 32 pts in ~12 months if worked down.
Vehicle 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 Dorchester County, SC · medium impact
• Review the inspections from Dorchester County, SC 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 100%
• Defensive-driving refresher on following distance and lane discipline
Projected: could improve up to 9 pts in ~12 months if worked down.
