In a location where there is a "No Parking" sign with a supplementary sign stating "Except Sundays and Holidays," it does not mean you may always park on Sundays or holidays.

Answer: True

Explanation

According to the Rules of the Road, supplementary signs supplement the meaning of main signs and specify the times or days when regulations apply. "Except Sundays and Holidays" means the restriction does not apply on Sundays and holidays, but you must still follow other parking prohibitions (such as legally prohibited places near intersections). Be careful with the double-negative trick in this question.
