you will most likely have a chance to plead it down. you want to tell the prosecuter you are willing to plead guilty to the crime you actualy commited (speeding whatever) but you have no intention of pleading guilty to a crime you did not commit.. providing you have a reasonable prosecuter, and a reasonably clean record.. they will ammend the charge to somethign less severe.. no one wants to have a trial for a traffic matter due to to an already over loaded court system..

this is what would happen in NJ.. this is SOUND legal advice for OUR state.. i don't know about there but its worth a try..
