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 99% 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.

- Assess English proficiency at hire and provide support/training where needed
- Prioritize the out-of-service items — they carry the heaviest weight
Brakes violations are the leading contributor to Vehicle Maintenance
High impactEstimated Vehicle Maintenance percentile of 86% 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.

- 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”
- 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 23.6% 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
A high share of violations are occurring in Cameron County, TX
Medium impact105 of 128 violations in the last 12 months (82%) came from inspections in Cameron 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 Cameron County, TX to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Drugs / alcohol violations are the leading contributor to Controlled Substances/Alcohol
Low impactEstimated Controlled Substances/Alcohol percentile of 33% is under the 75% line. In decent shape, but here's what's driving it.

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 NHTSA9 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 or phone numbers with 7 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.
