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.
Driver qualification / CDL / medical violations are the leading contributor to Driver Fitness
High impactEstimated Driver Fitness percentile of 84% 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 (391.1× · 16%
- Run a credential-expiration tracker; keep DQ files complete and the medical card on the driver
- Prioritize the out-of-service items — they carry the heaviest weight
A high share of violations are occurring in Solano County, CA
Medium impact14 of 46 violations in the last 12 months (30%) came from inspections in Solano County, CA. 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 Solano County, CA to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Following / lane / reckless violations are the leading contributor to Unsafe Driving
Low impactEstimated Unsafe Driving percentile of 54% is under the 65% line. In decent shape, but here's what's driving it.
- 392.2-SLLTCDState/Local Laws - Failed to obey a traffic control device - Permanent or Temporary - e.g., safety official, signal, sign, light, lane marking, other9× · 86%

False log / RODS violations are the leading contributor to Hours-of-Service Compliance
Low impactEstimated Hours-of-Service Compliance percentile of 36% is under the 65% line. In decent shape, but here's what's driving it.

- Retrain on correct logging and never letting a load pressure a driver into a false entry
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
Tires violations are the leading contributor to Vehicle Maintenance
Low impactEstimated Vehicle Maintenance percentile of 18% is under the 80% line. In decent shape, but here's what's driving it.

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 phone numbers with 35 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.
