Whenever a vehicle is to be parked in any metered parking lot, at any time when the lot is open for use and the meters are to be in operation, the driver of the vehicle, upon entering the parking space, shall immediately deposit, or cause to be deposited, in the proper parking meter, one or more proper coins of the United States of America as specified in the legend on the parking meter. Upon the deposit of the coin or coins, and placing the meter in operation, the parking space may be lawfully occupied by the vehicle for the time indicated on the meter. If any vehicle remains in any such parking space for such length of time that the meter indicates that the lawful parking time has expired, that vehicle shall be considered as being parked overtime, and the parking of a vehicle overtime shall be a violation of this subchapter; provided, every hour that a vehicle remains parked at a meter showing a violation shall constitute a separate violation of this subchapter.
