One of the main rules, which may apply here, is that you NEVER cross a solid white line. Where there appears to be a left turn, you are only allowed to make it if the line is broken. If it's solid, then you are breaking the law.

A number of people that I've spoken to were unaware of this.

This was a dotted line, what L...D.. are saying is that you have to wait for people behind you to pass before you can turn left.......

Seems a very strange one to me.
Never heard of it before.
Await clarification with interest.

So do I. Will let you know the outcome
