3 - RoadIcingState

Full qualified VSS Path: Vehicle.Safety.RoadIcingState
Description: Indicates whether the vehicle is currently at risk of icing-related loss of control or has detected such conditions affecting traction.
Comment: Derived assessment distinct from Vehicle.Exterior.RoadSurfaceCondition, which reports observed surface state; RoadIcingState reports the derived risk of icing-related loss of control. RISK can be elevated even when RoadSurfaceCondition reports DRY (black ice, freezing-rain onset), and NONE can hold even when it reports SNOW (low-speed packed snow with adequate winter-tire grip). May be derived from Vehicle.Exterior.RoadSurfaceCondition, Vehicle.Exterior.AirTemperature, Vehicle.ADAS.ESC.RoadFriction.MostProbable, and Vehicle.Exterior.RoadSurfaceTemperature. NONE indicates no elevated icing risk. RISK indicates conditions favor ice formation or onset of icing-related traction loss. DETECTED indicates active icing-related loss of control is occurring. UNKNOWN shall be used when the system cannot assess icing risk. Criteria for each state may be OEM specific. Primary consumers: driver-warning systems, ADAS interventions, and navigation systems (re-routing away from elevated-risk segments). Related to VSS issue #877 (Connected Safety signals).

4 - Rollover

Full qualified VSS Path: Vehicle.Safety.Rollover
Description: Indicates whether the vehicle has rolled over or is at risk of rollover.
Comment: May be derived from Vehicle.AngularVelocity, Vehicle.Orientation.Roll, and Vehicle.Orientation.Pitch signals. NONE indicates normal orientation. RISK indicates the vehicle is at elevated risk of rollover. DETECTED indicates a rollover event has occurred. UNKNOWN shall be used when the system cannot assess rollover status.

5 - VisibilityImpairment

Full qualified VSS Path: Vehicle.Safety.VisibilityImpairment
Description: Indicates whether reduced exterior visibility is currently creating a driving-safety risk, or such a condition has been detected.
Comment: Derived safety assessment layered on the Exterior observational signals Vehicle.Exterior.VisibilityCondition (dominant cause of reduced visibility) and Vehicle.Exterior.VisibilityDistance (quantitative range). VisibilityImpairment is cause-agnostic and reports only the derived, speed-relative safety risk on top of those signals; the cause itself (snow, fog, etc.) is carried by VisibilityCondition. May be derived from Vehicle.Exterior.VisibilityCondition and Vehicle.Exterior.VisibilityDistance, optionally combined with vehicle speed and stopping-distance context. NONE indicates visibility is adequate for current driving conditions. RISK indicates visibility is degrading toward a level that materially raises driving risk for the current speed. DETECTED indicates visibility impairment severe enough to require driver action is active. UNKNOWN shall be used when the system cannot assess visibility impairment. Criteria for each state may be OEM specific. Primary consumers: driver-warning systems, navigation systems (re-routing on impaired visibility), and emergency dispatch systems. Related to VSS issue #877 (Connected Safety signals).
