If you have had a ticket in the last three years, then your best bet is to hire a lawyer to help you. If the case is dismissed, you do not have to pay the court costs. If you plead not guilty, but are found guilty, then you would have to pay.
Assuming the new crime qualifies and that you were not previously placed on probation, you should be eligible for a deferred prosecution. You may not be eligible for an expungement this time, though. Read the certifications you make by signing the agreement at this link.
