(A) It shall be unlawful for the owner or operator of any vehicle to park or allow his or her vehicle to be parked in a parking space regulated by a parking meter for more than the maximum period of time which can be purchased at one time. Insertion of additional time is unlawful.
(B) No owner or operator of any vehicle shall park or allow his or her vehicle to be parked in such a space when the parking meter therefore indicates no parking time allowed, whether such indication is the result of a failure to deposit a coin or to operate the lever or other actuating device on the meter, or the result of the automatic operation of the meter following the expiration of the lawful parking time subsequent to depositing a coin therein at the time the vehicle was parked.
