My best friend got a citation for having an open container of beer in the backseat. He went to all of his court appearances, but couldn't raise up the money to pay the fine. He never went back. would a warrant have been issued for his arrest for something so minor?
I've seen cases like this result in a bench warrant. If the sentence or penalty imposed is a fine, the case is not over until the fine is paid. Failing to pay the fine is the equivalent to disobeying a court order, and can result in a bench warrant.
