Safety trends & next-run projection
Where each BASIC sits today, how it ranks against peers, and where it’s heading at the next monthly SMS run.
FMCSA keeps the Crash Indicator percentile private, and its measure needs a power-unit history public data doesn’t expose — so it can’t be estimated yet. VioCodes now records power units monthly, so a calibrated Crash estimate should light up over time. These are the public crash facts (all state-reportable crashes count, regardless of fault).
“Projected” estimates the next monthly SMS run from inspections on record now. FMCSA marks the BASIC percentile itself “Not Public,” so the percentile shown is a VioCodes estimate of how the carrier ranks against its peers, presented as a likely range (shaded on the gauge) and calibrated against real carriers. Crash Indicator has no public estimate — FMCSA keeps its measures fully private. Estimates, not official FMCSA figures. Not affiliated with FMCSA.
Recommendations
What’s driving each score, what to do about it, and where it could go.
Log / ELD device violations are the leading contributor to Hours-of-Service Compliance
High impactEstimated Hours-of-Service Compliance percentile of 77% is at/over the 65% intervention line. Carriers with a BASIC in alert are prioritized for enforcement (warning letters, audits) and inspected more often — which tends to generate still more violations.

- 395.8E-HOSPDHOS (Property) - No driver may make a false report in connection with a duty status. Explain3× · 31%
- Make sure the ELD is registered, working, and drivers know how to log in and certify daily
- Prioritize the out-of-service items — they carry the heaviest weight
Vehicle out-of-service rate exceeds the national average
High impactVehicle OOS rate is 27.5% vs the 22% national average. Carriers above the national OOS average draw more enforcement attention (audits, roadside stops) and can see higher insurance premiums.
- 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
- Reinforce thorough pre-trip and post-trip inspections; retrain where needed
Lighting / lamps violations are the leading contributor to Vehicle Maintenance
Medium impactEstimated Vehicle Maintenance percentile of 79% is close to the 80% intervention line — worth getting ahead of before it crosses.

A high share of violations are occurring in Seward County, KS
Medium impact9 of 51 violations in the last 12 months (18%) came from inspections in Seward County, KS. That can mean tougher enforcement there or simply more of your miles run through it — either way it's worth a look.
- Review the inspections from Seward County, KS 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

- 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
Controlled Substances/Alcohol needs attention
Low impactEstimated Controlled Substances/Alcohol percentile of 0% is under the 80% line. In decent shape, but here's what's driving it.
- Review recent inspections with violations in this BASIC and take remedial action with drivers/equipment

Connections
carrier graphThis carrier shares VINs with 9 other carriers — review the connections below as part of your vetting.
Shared VINs come from FMCSA roadside-inspection records — a vehicle inspected under more than one carrier, often a fleet transfer or trailer interchange. Other links come from the FMCSA census. Shared identifiers are common and often legitimate — treat these as leads to investigate, not proof of wrongdoing.
