Find out the total amount you owe. When you go to court have the total amount with you. This may prevent the Judge from adding any penalties. You may also hire a lawyer and have that lawyer go to court ready to pay the entire amount. There's no guarantee you won't receive additional punishment as a result of the violation, but you will have a better chance if you can pay the entire amount owed.
