How high on a post? can you see it from your driver's vantage point from where you were ticketed? are there double lines or not?

If you intend to go to court, you need to take some pictures of what the situation looks like, from your driver's seat, at that same time of day. traffic control devices can't be hidden, obscured, or placed in a manner so that you can't see them. there are rules that govern placement of these objects.

My wife had a similar situation. I did all of the above, made a big presentation board, etc. I was fighting it because I couldn't believe what she did was wrong. At the last minute, I actually read the law, and found that what she did was not wrong!

At the hearing/trial, the cop totally changed his story about what had happened. I actually think it was not out of malice, but I think he didn't remember - it had been 2 months since the ticket, and I can barely remember some obscure work item from 2 months ago. In this case, though, I was shocked, because it was so far from the truth.

In the end, the judge ruled that her maneuver was not, in fact, against the law (at least against the section of the law she was cited for - I did not research the entire code to see if she was mis-cited).

So, prepare your case, and read the law. Then decide if you have a case, and if it's really worth it.
