Latest inspection 2026-10-08. “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
A high share of violations are occurring in Weld County, CO · medium impact
• Review the inspections from Weld County, CO 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 89% · Following / lane / reckless 11%
• Zero-tolerance belt policy; verify with in-cab camera or spot checks
Projected: could improve up to 7 pts in ~12 months if worked down.
False log / RODS violations are the leading contributor to Hours-of-Service Compliance · low impact
False log / RODS 51% · Following / lane / reckless 36% · Log / ELD device 13%
• Audit ELD edits and duty-status annotations weekly; a false log is a high-severity, high-visibility violation
• Retrain on correct logging and never letting a load pressure a driver into a false entry
Projected: could improve up to 18 pts in ~12 months if worked down.
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
Brakes violations are the leading contributor to Vehicle Maintenance · low impact
Brakes 42% (6 OOS) · Lighting / lamps 33% · Tires 18% (4 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 33 pts in ~12 months if worked down.
