Final answer:
The late fee assessed after fourteen calendar days from the citation issue date is $20.00.
Step-by-step explanation:
The late fee assessed after fourteen calendar days from the citation issue date is $20.00. This is a straightforward calculation based on the information provided. No late fee is applied while a citation is pending appeal. However, the question clearly states that a $20.00 late fee is assessed after the 14-day period if the citation is not under appeal.
