You should be safe, i hear that your rear wheels must pass the last line completely before it becomes an offense (someone correct me if im wrong). If you do get a fine, request a picture of the offense.
My mate got done for running the yellow, yea stupid him, but when he requested a pic, it clearly showed his last wheel still on the last line. In this situation the car must pass the 3 lines completely before the camera goes off, its got something to do with the sensors on the road placed farther back from the lines, clearly the rta's ****up

He told me he sent them a letter stating this but in reply he got something technical about how the sensors are placed and how they work etc, but clearly he was in the safe as the rules state you must pass the last line, or so i was told.

That safety cam is a joke and i reckon its programed way earlier. Its constantly going off like every 10-15mins
