It's mirror, signal & then make the move. This dozy woman maybe signalled (couldn't tell, I was approaching & she was turning left. It wasn't flashing as she pulled out but maybe she cancelled it quick) but she most certainly didn't look. What she did was basically not stop or even slow down as she approached the junction, pulled out in to oncoming traffic and THEN looked.
Obviously not required to have a licence over here eh? Just drive how you want and cut people up everywhere. It's your road now after all...
