SETRA truck models
VIN-resolved SETRA model coverage, observed fleets, level-scoped roadside OOS outcomes and the BASIC categories most often recorded on attributable inspections.
Interpretation guardrail
These roadside results reflect operators' maintenance and duty cycle as much as the vehicle. They are not evidence of a manufacturer defect. OOS rates and failure frequencies are normalized per inspection, never presented as a raw count pretending to be a rate.
Violation detail is as of Jun 16, 2026; it is not current. A missing platform or cab label means “not established,” never “no.”
Observed platform footprint
Unit volume covers resolved inspection records; fleet totals deduplicate USDOT operators at this manufacturer grain.
Reported trucks sum FMCSA truck_units across distinct observed fleets after the existing plausibility clamp. It is fleet context, not a count of this manufacturer's vehicles, and it never uses power_units or MCS-150 mileage.
Level-scoped OOS outcomes
963 inspections had exactly one resolvable power unit and form the attribution population.
Top BASIC failure categories
Attributable vehicle violations grouped only through the Jun 16, 2026 CFR-section reference; frequencies are per 100 attributed inspections.
Vehicle Maintenance: 362 violations; 80 marked OOS.
Unsafe Driving: 120 violations; 8 marked OOS.
HOS Compliance: 3 violations; 0 marked OOS.
Driver Fitness: 1 violations; 1 marked OOS.
