I've heard that the Airport is planning to apply this 24-hour time limit to free parking, but that is not how the statute reads:
(b) An electric vehicle on which an electric vehicle license plate is affixed shall be exempt from payment of parking fees, including those collected through parking meters, charged by any state or county authority in this State, except that this exemption shall not apply:
(1) For more than two and one-half hours of metered parking, or the maximum amount of time the meter allows, whichever is longer; or
(2) To parking fees assessed in increments longer than one twenty-four-hour day, including weekly, monthly, or annual parking permits.
(b)(2) does not say the limit is 24 hours is the limit, it says that EV's are not eligible to receive free parking if it is charged in greater than 24 -hour increments. The airport charges by the hour and then by the day (read 24 hours). Two days in the lot is still just two increments of 24 hours.
Anyone willing to go and challenge the State in court on its interpretation?
