Latest inspection 2026-08-10. “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
Lighting / lamps violations are the leading contributor to Vehicle Maintenance · high impact
Lighting / lamps 66% (2 OOS) · Brakes 26% (7 OOS) · Windshield / glass / mirrors 4%
• 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 50 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 Kinney County, TX · medium impact
• Review the inspections from Kinney County, TX to spot recurring issues
• Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Seat belt violations are the leading contributor to Unsafe Driving · low impact
Seat belt 100%
• Zero-tolerance belt policy; verify with in-cab camera or spot checks
Projected: could improve up to 5 pts in ~12 months if worked down.
Hours-of-Service Compliance 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
