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.
False log / RODS violations are the leading contributor to Hours-of-Service Compliance
High impactEstimated Hours-of-Service Compliance percentile of 69% 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.
- 395.8A1-HOSPHOS (Property) - Failing to have a record of duty status using the method prescribed1× · 29%
- 395.8A-ELDELD - No record of duty status (ELD Required)1× · 29%
- 395.8F01Drivers record of duty status not current1× · 21%
- Audit ELD edits and duty-status annotations weekly; a false log is a high-severity, high-visibility violation
- Retrain on correct logging and never letting a load pressure a driver into a false entry
- Prioritize the out-of-service items — they carry the heaviest weight
English language violations are the leading contributor to Driver Fitness
High impactEstimated Driver Fitness percentile of 92% 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.
- 391.11B2-QDriver cannot satisfy the English language proficiency requirements of 391.11(b)(2) in accordance with the current corresponding FMCSA enforcement guidance (391.5× · 59%

Brakes violations are the leading contributor to Vehicle Maintenance

- 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 and driver out-of-service rate exceeds the national average
High impactVehicle OOS rate is 42.9% vs the 22% national average. Driver OOS rate is 23.8% vs the 6.7% 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 La Salle County, TX
Medium impact17 of 67 violations in the last 12 months (25%) came from inspections in La Salle 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 La Salle County, TX to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
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 or addresses with 65 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.
