No Proof Of Insurance leads to warrant for arrest

Following the no proof of insurance problem the nephew recently had, he was informed by the officer there was actually a warrant out for his arrest.  Apparently the nephew got a ticket back in the December and failed to pay it or appear in court.  Now he owes $300.  Really?  So even though he has insurance now to get out of the recent ticket, there is no way around the December ticket.  It's times like this that I wonder why I even try at all to help the boy.
