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.
Speeding violations are the leading contributor to Unsafe Driving
High impactEstimated Unsafe Driving percentile of 78% is at/over the 60% 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.
- 392.2-SLLS4State/Local Laws - Speeding 15 or more miles per hour over the speed limit2× · 63%
- 392.2-SLLS3State/Local Laws - Speeding 11-14 miles per hour over the speed limit2× · 29%
- 392.2-SLLS2State/Local Laws - Speeding 6-10 miles per hour over the speed limit2× · 8%
- Coach the drivers with speeding violations directly — Unsafe Driving points are weighted heavily
- Set and enforce a governed road speed; review telematics/dashcam speed events weekly
False log / RODS violations are the leading contributor to Hours-of-Service Compliance
High impactEstimated Hours-of-Service Compliance percentile of 93% is at/over the 60% 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 prescribed4× · 49%
- 395.8E-HOSPDHOS (Property) - No driver may make a false report in connection with a duty status. Explain1× · 29%
- 395.8E-HOSPDOOSHOS (Property) - Driver produces a false record of duty status that concealed an HOS limitation violation after the last rest period. Explain:1× · 13%
- 395.3A2-PROPNDriving beyond 14 hour duty period (Property carrying vehicle) - Nominal Violation1× · 3%
- 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
Vehicle and driver out-of-service rate exceeds the national average
High impactVehicle OOS rate is 38.5% 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
Tires violations are the leading contributor to Vehicle Maintenance
Medium impactEstimated Vehicle Maintenance percentile of 73% is close to the 75% intervention line — worth getting ahead of before it crosses.

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
VINs via NHTSA25 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 addresses with 45 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.
