I would consult an attorney in your area but generally if you are going to pay the fine IN FULL then they won't lock you up. I would call the court, find out the total you owe, and then go pay it off. The court just wants the money. You can also have someone else go pay it off if you're scared.
Often there is an extra $100 warrant fee. Don't wait to get arrested unless you like jail food.
Please do not confuse the casual and impersonal exchange in this or any legal chat room with entering into an attorney-client relationship. If your situation warrants formal legal assistance, you should begin the process of hiring Mr. Aarons at firstname.lastname@example.org or another lawyer to consider all of the relevant facts and law in your case.
