As of 8/27/13, the 24-hour rule has been challenged and overturned: http://bit.ly/16ZUVe5
'...Honolulu resident Dale Podoll challenged the new charge on grounds that it conflicted with the law exempting vehicles with “EV” license plates from paying parking fees.
After consulting with the state Attorney General’s Office, the department told him last week that he would receive a refund. Podoll alerted Kokua Line to the reversal.
As we reported earlier, an electric vehicle, with an EV license plate, is allowed to park for free at state or county parking lots or metered stalls with these exceptions: while parked at a charging station; while parked for more than 2 1/2 hours at a meter or the maximum amount of time allowed, whichever is longer; while parked for longer than one 24-hour day, including under weekly, monthly or annual parking permits.
Transportation spokeswoman Caroline Sluyter had said that meant, “At the airport, electric vehicles get the first 24 hours free and then have to pay the regular rate.”
Asked about Podoll’s challenge, Sluyter said that after consulting with the Attorney General's office, the department was advised that the legislative intent was that electric vehicles should not be charged for parking in public lots.
“A refund will be issued through our parking concessionaire” and posted signs will be changed, Sluyter said.
She also said anyone else with an electric vehicle and a receipt showing the paid parking fees after the first 24 hours at Honolulu Airport also is entitled to a refund.
What that means for other state or county parking lots that offer long-term parking is not certain. Sluyter said the department had asked only for clarification regarding airport fees. ...'
