There are very few routes that you can take to convert moving violation into nonmovingviolation. In any case, if you wish to have the best possible chance at changing the violation to a lesser offense, you should hire a traffic attorney who has experience in cases like these.
If you have been cited for a moving violation and wish to convert it to a nonmoving violation, you need to first plead not guilty to the charges.
A nonmoving violation incurs a lower fine and does not impact your driving license record by much. These include violations like parking tickets and fix-it tickets. Moving violations on the other hand are awarded when you have broken a traffic law while the car was in motion. For instance, a speeding infraction falls under this category.
Once you plead not guilty to the moving violation in traffic court, a date for the trial hearing is set. You need to consult with your traffic attorney and speak with the prosecutor before the actual trial hearing. Only the prosecutor will be able to reduce the citation to a nonmoving violation. Convey to the prosecutor that you intend to plead not guilty to the moving violation but that you would be willing to plead guilty to a lesser charge of a nonmoving violation and pay the requisite fine. More often than not, the prosecutor will be willing to cut a deal with you.
The prosecutor will then create a document stating that you are being charged for a nonmoving minor violation. Sign this document and plead guilty to this offense. Having competent representation will make this situation much easier though.
