I got a 60 fine outside kebab and wine a few weeks ago, some street camera got me, I didn't know until letter came that it was controlled there, thought I was ok there. Wrong. However when I went back to check after getting the letter, the sign did say clearly. My fault/assumption. Read the signs. However, I think that when NEW signs go up or they're CHANGED, the sections of the road affected should be sprayed in fluorescent day-glo pink paint (which remains for a month) to warn potential parkers and all passers by that there's money to be lost here if you don't adhere to the regs.
