What happens if you drive through a toll without paying in NH?

Excuse me, could you please clarify what the consequences are for driving through a toll in New Hampshire without making the necessary payment? Are there any fines or penalties that one might face? Additionally, is there a process in place for addressing such instances and ensuring that the toll is eventually paid? I'm just trying to get a better understanding of the procedures surrounding unpaid tolls in New Hampshire, as I've heard varying information about the matter.
