I have just received a fine (in the post) for £180 for landing in a box junction. My memory is terrible so I have no idea whether I was or wasn't in the area cited on the form (although I guess I or my husband must have been) but I am normally really really careful about this. Do you think I should contest this - if the lights changed or if somebody jumped in front of me what could I have done, etc and I'm sure they change the lights deliberately quickly to catch people as they move across. If I fight it what do you think my chances are?
