The fine is small, it's more the principal. I recently moved to a new neighborhood. My side of the street has parking, and there are cars regularly parked all along it, at all hours of the day. There are no signs posted regulating parking on this side of the street in any way. Last night I was given a ticket for being parked on the street between 2-6am. I looked up the code for the neighborhood, and the policy is definitely on the books. My argument with this (besides the fact that it is a stupid law), is that I don't understand how they can enforce an un-posted policy. I would understand the implicit expectation of behavior if I, for example, parked on my neighbors front lawn. However, I feel this is different. I've never heard of this type of policy, and everywhere else I have lived, parking rules (ex. snow routes, parking stickers, etc) were always explicitly posted. Is ignorance a reasonable defense in this particular occasion?
So now that I've been here a couple years, I've learned a couple of things. There are one or two signs floating around the entrances to the town. 18pt font and impossible to read. Most likely intentionally
I wasn't able to read the sign from my vehicle even once I knew where it was.
I also learned from the locals that this was just the local police hustle for people from out of town. I got about half a dozen more tickets, in the next six months, never paid them and the police just gave up, and found someone else to pester.
