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.
Brakes violations are the leading contributor to Vehicle Maintenance
High impactEstimated Vehicle Maintenance percentile of 100% 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.

- 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 38.1% 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 Hidalgo County, TX
Medium impact73 of 73 violations in the last 12 months (100%) came from inspections in Hidalgo 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 Hidalgo 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
Hours-of-Service Compliance needs attention

- Review recent inspections with violations in this BASIC and take remedial action with drivers/equipment
Controlled Substances/Alcohol needs attention

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.

Connections
carrier graphThis carrier shares VINs, addresses or emails with 1380 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.
