R156 / Generalization

On Road Ego Vehicle is a Traveling or Non Traveling Ego Vehicle

---

When an On Road Ego Vehicle is in a Driving Lane it is considered to be traveling. Otherwise it is not.

Certain driving rules and policies apply when an On Road Ego Vehicle is traveling, such as the requirement that it always be in a Driving Lane (or transitioning between them) that don’t apply to a vehicle that may be parked or coasting in a Road Segment somewhere like a Shoulder or Exclusion Lane. In particular, we can always ask an On Road Ego Vehicle, ‘What Driving Lane are you in?’ and always get an answer, even during a lane transition.
