I recently received a citation for 42 in a 25 zone. The officer got me on radar, and I have no doubt that I was speeding so that isn't the issue. My question is this; is radar enforceable in places where it is not indicated? There was no indication that radar is enforced under the speed limit sign.
I know it may seem like a stupid question to some of you, but I am new to this whole getting pulled over for speeding thing. So are those signs just a courtesy reminder in some areas, or do they actually mean something? Do I have any chance, or should I just pay the fine and forget about it? Thanks in advance.
