Recommendations — what's driving each score
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 Dimmit County, TX · medium impact
• Review the inspections from Dimmit County, TX to spot recurring issues
• Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
