You probably got that fine because the judge thought it was something else. You should be aware that under this statute the Motor Vehicle Commission can, in its discretion, suspend your license for up to two years. I don't know if they do this or under what circumstances they would. If you get anything from MVC, call a lawyer.

Did you go before the Court and then were assessed the $56 fine? It is possible that you may have pled to an ordinance violation. Either way scan both the ticket and the receipt from the Court and keep in a safe place in the event that the MVC comes knockin'. Good luck.
