If an offence is a second or subsequent such offence, he or she is liable to a fine not exceeding €1,500, and if the offence is a third or subsequent such offence committed within 12 months he or she is liable to a fine not exceeding €1,500 or imprisonment for a term not exceeding three months, or both.
