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.
Tires violations are the leading contributor to Vehicle Maintenance
High impactEstimated Vehicle Maintenance percentile of 97% 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.

- Gauge and thump every tire on the walk-around, including inner duals
- Replace before tread hits the limit; correct low pressure immediately
- 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 63.6% vs the 22% national average. Driver OOS rate is 11.1% 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
Following / lane / reckless violations are the leading contributor to Hours-of-Service Compliance
Medium impactEstimated Hours-of-Service Compliance percentile of 64% is close to the 65% intervention line — worth getting ahead of before it crosses.

- Defensive-driving refresher on following distance and lane discipline
- Prioritize the out-of-service items — they carry the heaviest weight
A high share of violations are occurring in Riverside County, CA
Medium impact12 of 51 violations in the last 12 months (24%) came from inspections in Riverside 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 Riverside County, CA 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

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

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 5 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.
