You asked

I have average speed camera requests. I traveling to work on the M4 towards London between junction 3 and junction 1 and I notice several new average speed cameras but no average speed camera sign before them. Can you please confirm if these are actually average speed cameras? And if yes, if they have already gone live? And if not when are they going live?
