I don't think they check warrants for marriage licenses. Good luck.

Technically, with an open warrant you can arrested anywhere you are found. However, it is unlikely that you are going to be arrested when you get married. I doubt that they check for open warrants when you go to get married. At some point, it would be wise to consult with a traffic ticket attorney and resolve your open warrants/traffic violations.
