I wouldn't think the length of imprisonment would be longer than it would take to see a judge in most cases.

The cycle I'm referencing is usually fail to pay your fines, at some point dependent upon jurisdiction and familiarity to the court, arrest warrant is issued, if caught you are arrested and taken to jail to be held until you see a judge, accrue more fines, possibly repeat.

I'm not making statements that this will happen, only that it absolutely can and does happen to people.
