A violation of this article or of such local law, ordinance or regulation is hereby declared to be an offense, punishable by a fine not less than $250 nor more than $1,000 or imprisonment for a period not to exceed six months, or both, for conviction of a first offense; for conviction of a second offense, both of which were committed within a period of five years, punishable by a fine not less than $1,000 nor more than $2,500 or imprisonment for a period not to exceed six months, or both; and, upon conviction for a third or subsequent offense, all of which were committed within a period of five years, punishable by a fine not less than $2,500 nor more than $5,000 or imprisonment for a period not to exceed six months, or both. A violation shall be deemed to have first occurred from the date of written notification of violation issued by the enforcement officer or from such date as may be designated in such written notice. However, for the purpose of conferring jurisdiction upon courts and judicial officers generally, violations of this article, or of such local law, ordinance or regulation, shall be deemed misdemeanors, and for such purpose only, all provisions of law relating to misdemeanors shall apply to such violations. Each day's continued violation shall constitute a separate additional violation.
