What happens if you don't show up to court in New York?

Usually if you dont show up at court anywhere you get into trouble. Sometimes they deal with the offence in your absence and this can bring higher fines. Other times they may get a bit stiff; and issue a summons for your attendance. If you dont appear on a summons they issue a warrant and they arrest you if they catch you. A warrant can follow you around for as long as you live... until a day comes when they grab you. If it goes to the warrant stage, jail is likely.
