you might want to look at the markings in the road and the rules around those signs. seem to remember it being you can take which ever lane without making any sharp turns. and i think off the top of my head you are meant to chose your lane before it splits, not divert in the middle of it like that.
i only know this after having done that on my motorbike, pretty much same situation, chancing it to get past a bus. then i got pulled over and they had a word about it
