What's the difference between an infringement fee and a fine?

When you are issued a ticket (an 'infringement notice') the monetary penalty recorded on it is called an 'infringement fee'. If the infringement fee is not paid in full by the due date it is referred to the Ministry of Justice for enforcement, when it becomes a 'fine'. For more information see on infringements notices and fees.
