Encroachment

An encroachment is any time a vehicle leaves the travelled way.   The travelled way is define as the lanes of travel so as soon as any portion of the vehicle has crossed the white (i.e., right) or yellow (i.e., left) edgelines the vehicle has encroached on the roadside.   Driving onto the shoulder, for example, IS an encroachment since the vehicle has left the travelled lane.
