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.
English language violations are the leading contributor to Driver Fitness
High impactEstimated Driver Fitness percentile of 94% is at/over the 80% 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.

- Assess English proficiency at hire and provide support/training where needed
A high share of violations are occurring in El Paso County, TX
Medium impact115 of 115 violations in the last 12 months (100%) came from inspections in El Paso County, TX. 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 El Paso County, TX to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Unsafe Driving needs attention
Low impactEstimated Unsafe Driving percentile of 0% is under the 65% 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

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
VINs via NHTSA27 distinct vehicles seen in this carrier’s roadside inspections.
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 with 12 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.
