First offense. Any person who violates any provisions
of this chapter subject to a penalty shall, upon conviction thereof,
forfeit not less than $25 nor more than $200, together with the cost
of prosecution. In the event of a failure to pay such forfeiture,
where no showing of indigence is made, the defendant may be imprisoned
for no more than 90 days, as the court deems fit, or until such judgment
is sooner paid.
