Don't know how it works there. For traffic court here, NJ, I've always taken matters into my own hands. The last ticket I received was for failing to update my address. I argued to the prosecutor that the law only required me to have an address where I received mail. He only cared that I updated it by the time I made my appearance and quickly dismissed. However, the court cost was actually more than the ticket and I made a point to ask him to waive that as well, which he did.

There are other sorts of 'administrative' fees that are nearly impossible to waive. Things like license reinstatement, points surcharges, and costs from MVC (DMV) usually can't be waived by the court as it isn't the court that imposes them.
