What is the exact letter of the law on how clear a parking sign should be? - should i sign california certification of trust

I got a ticket today, and I'm not very happy. It was parked in a "zone of the holders of parking tickets. I was not aware and even if it seems a sign, I do not think this book.
Had been parked on my return to the car, where previously a number of trucks had, I saw a small sign on the size of a fence put Diddy in someones front yard. This is an official sign, but would identify how on earth do I?
Basically, what the law is unclear how and to what extent should such signs?
