Will a Carbondale city ordinance violation of underage drinking result in the suspension of my drivers license?

An officer saw me take a drink from a plastic cup at a bar. I received a city ordinance violation citation for underage drinking. The officer didn't let me try to explain what the drink was, did not ask or give me a breathalyzer, and just continued to write and give me the citation. I lost my citation and the date on my citation passed without me realizing it. I had a fender bender yesterday only to find this out and that I had a warrant. I bailed out about an hour later but I don't know what I am supposed to do. Should I call the courthouse Monday morning, go there, or wait for something in the mail? Since my citation date lapsed, will this now go to the S.O.S? I'm 19, work full time, live on my own, and I really can't lose my license. I can't afford an attorney.
