You do need a license, I doubt they are going to lock you up for it though, especially right now, unless you have a string of the same charge? Or are on probation for other traffic charges? If not you might ask for a continuance for dismissal, where they agree to hold off on your punishment for a year as long as you have no same or similar offences in that time. Get to court early and try to talk with the prosecutor, if there are other circumstances you have not shared with us that make this more serious than it seems, get a lawyer, or plead not guilty and have the court appoint you one if you can't afford one. (be ready to prove you are indigent though) at this point they should really try to make a deal with you as it is not cost effective to have a trial for such a trivial matter. They don't want to waste jail space on things like this and there is the Corona...they don't want to have to take care of you if you get it in there. Best of luck.
