D1 seems inadequate...
I'd just say D1.
While the road surface may be wide, the actual driveable space is still restricted to one vehicle, although often I don't see overtaking restrictions (either signed or solid white lines) on these types of road, so I wouldn't call it an D1.5
Sure you could call them WD1 though.
The examples given in this thread (whereby each carriageway is only wide enough for one vehicle to drive along it at a time) are obviously D1. However, where the outer lane has been hatched to discourage overtaking, but where the carriageway is still wide enough to overtake and there is no actual restriction in place to prevent overtaking (for example) I think we're probably still talking about a D2.
And, of course, there are also many examples of old stretches of D2 where one side has been hatched out (and restrictions against overtaking imposed) while the other side still allows overtaking. See here. Would that be a D2+1?
And what about this example: at one end it is indisputably D2, but at the other end it has been whittled down to a D1. It's all the same piece of road, and I'm not sure the width of the original carriageways (which were once D2 throughout) has ever been changed.
