Latest inspection 2026-08-19. “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 Clay County, MN · medium impact
• Review the inspections from Clay County, MN to spot recurring issues
• Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Speeding violations are the leading contributor to Unsafe Driving · low impact
Speeding 58% · Following / lane / reckless 26% · Seat belt 16%
• Coach the drivers with speeding violations directly — Unsafe Driving points are weighted heavily
• Set and enforce a governed road speed; review telematics/dashcam speed events weekly
Projected: could improve up to 13 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 65% · Following / lane / reckless 32% · Log / ELD device 2%
• 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 19 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
Lighting / lamps violations are the leading contributor to Vehicle Maintenance · low impact
Lighting / lamps 53% (4 OOS) · Brakes 27% (1 OOS) · Load securement 16% (2 OOS)
• 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 34 pts in ~12 months if worked down.
