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.
Lighting / lamps violations are the leading contributor to Vehicle Maintenance
High impactEstimated Vehicle Maintenance percentile of 84% is at/over the 75% 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.

- 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
Vehicle out-of-service rate exceeds the national average
High impactVehicle OOS rate is 26.3% 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
Speeding violations are the leading contributor to Unsafe Driving
Low impactEstimated Unsafe Driving percentile of 10% is under the 60% line. In decent shape, but here's what's driving it.
- 392.2-SLLSWZState/Local Laws - Speeding work/construction zone1× · 65%
- 392.2-SLLS2State/Local Laws - Speeding 6-10 miles per hour over the speed limit1× · 13%
- 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
Hours-of-Service Compliance needs attention
Low impactEstimated Hours-of-Service Compliance percentile of 0% is under the 60% 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
Controlled Substances/Alcohol needs attention

Inspection & crash map
live · FMCSA MCMISEvery inspection and crash on record — hover a point for the summary, click for full detail (codes, severity, CSA points).
CSA points = violation severity weight × FMCSA time weight (3× in the last 6 months, 2× at 6–12, 1× at 12–24). Points are spread within each state — FMCSA records the inspection state, not an exact location. Source: FMCSA MCMIS.
Equipment

Equipment is inferred from VINs recorded on roadside inspections (FMCSA MCMIS), decoded via the NHTSA vPIC API — it reflects vehicles inspected, not a current fleet roster.

Connections
carrier graphThis carrier shares VINs, addresses, phone numbers or officers with 5 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.
