Methodology
Counts represent the number of ViolationEvent rows in FMCSA inspection records where a vehicle with a Series 60 engine was present on the same inspection. The linkage is: VINRecord (engine_model = “Series 60”) → VINRecord.vin → InspectionUnit.vin → ViolationEvent.inspection_id.
This is a co-occurrence count, not a causal attribution. Many of the top codes (brake systems, lighting, hours of service) are common across all heavy-truck inspections. The engine model does not cause most of these violations. Where an engine-specific violation does appear high in the list (emissions, fluid leaks, EGR-related codes), it may reflect a pattern tied to that powertrain. Always verify against current FMCSR regulations before drawing compliance conclusions. “% of Top 20” is computed against the sum of the top-20 violation counts shown, not all violations for this engine.
