Latest inspection 2026-09-04. “Projected” recomputes the SMS formula on today’s record — an estimate, not an official FMCSA figure. “Est. %ile” is a VioCodes estimate of how the carrier ranks against its peers (FMCSA marks the percentile itself “Not Public”), shown as a likely range.
Recommendations — what's driving each score
Brakes violations are the leading contributor to Vehicle Maintenance · high impact
Brakes 45% (6 OOS) · Lighting / lamps 19% (2 OOS) · Tires 19% (3 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 35 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 Orange County, CA · medium impact
• Review the inspections from Orange County, CA to spot recurring issues
• Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Driver Fitness needs attention · low impact
• Review recent inspections with violations in this BASIC and take remedial action with drivers/equipment
Controlled Substances/Alcohol needs attention · low impact
• Review recent inspections with violations in this BASIC and take remedial action with drivers/equipment
