No, of course you don't have to plead guilty. If you fight it, like I have said, you could probably get the matter dismissed.
I only brought up the plea to let you know that even if you were to resolve it with a plea, this charge is the criminal court equivalent of a traffic offense. That is, it's a violation and not a crime, even at its worst. It carries a maximum sentence
of 15 days in jail and/or a fine of up to $250. If you wanted a plea, you could pay a small fine, be done with it and it will seal within a year, after which nobody would find it.
If you want to fight the case on the other hand, you must plead not guilty
. However, to fight the case you have to either show up or hire a lawyer to show up for you. If you do nothing at all, I can assure you that a warrant will be issued for your arrest.
