A violation of this chapter is hereby declared to be an offense punishable by a fine not to exceed $350 or imprisonment for a period not to exceed six months, or both, for a conviction of a first offense; for a conviction of a second offense, both of which were committed within a period of five years, by a fine of not less than $350 nor more than $700 or imprisonment for a period not to exceed six months, or both; and upon conviction of a third or subsequent offense, all of which were committed within a period of five years, by a fine of not less than $700 nor more than $1,000 or imprisonment for a period not to exceed six months, or both. Each weeks' violation after notice shall constitute a separate additional violation. However, for purpose of conferring jurisdiction upon courts and judicial officers generally, violations of this chapter shall be deemed misdemeanors and, for such purpose only, all provisions of law relating to misdemeanors shall apply to such violations.
