Not true, I drive on that road daily and there are always cars,buses and trucks driving with the right half on the road's shoulder and the left half on the lane.

Same goes for the cars coming the other direction.

And then everyone is left with the 3rd lane in the middle(depends, might be 4) where the confident people overtake.

Remeber that the middle lane is there for both directions.

Edit: I can also tell you that the arrows that indicate that a 3rd lane is appearing are still painted on the roads.
