I got a ticket for not yielding the right of way to some cars, and even though I was never stopped by a cop before, I still got the ticket. Is it true that when you get a ticket, the police is supposed to ask for you to sign something? Because, I didn't sign anything, and where it said (defendants signature) Thye police officer just wrote "SERVED" what does that mean? Did I get away without getting a ticket, or what?

Check your state laws. Usually, the signature is just your agreement to either pay the ticket or appear in court. But your acquiescence isn't really needed for that; if you don't sign the ticket where required, the cop has no choice but to arrest you on the spot.
