I was thinking about your reply to @jefmcg where it doesn't sound as if she was waiting at the lights. And as she was turning right she would be a reasonable way from the pavement.
The point I was making is if you see a HGV too close whether moving or not, best is to move away or fall back even if you have right of way. Very similar to pacing. Sorry if I was not clear or misinterpreted what Jeff said.
ps. I hope the Lambeth Tipper case finally forces a ban for these types of vehicles during peak period. Her stature would be immensely helpful.
