Recommendations — what's driving each score
Following / lane / reckless violations are the leading contributor to Hours-of-Service Compliance · high impact
Following / lane / reckless 38% (2 OOS) · Log / ELD device 30% · False log / RODS 27% (1 OOS)
• Defensive-driving refresher on following distance and lane discipline
• Prioritize the out-of-service items — they carry the heaviest weight
Projected: could improve up to 25 pts in ~12 months if worked down.
A high share of violations are occurring in Riverside County, CA · medium impact
• Review the inspections from Riverside County, CA 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 48% · Following / lane / reckless 36% · Other 8%
• 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 12 pts in ~12 months if worked down.
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 38% (11 OOS) · Lighting / lamps 25% (8 OOS) · Tires 25% (16 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 19 pts in ~12 months if worked down.
