Please do not park in ineligible parking spots. On Oahu, in Hawaii, car-towing seems a big business. The car may likely be towed, and unfortunately you will be responsible. Towing fees are around $150.00
If towed please understand that is unfortunately your cost. The same for tickets, such as parcking tickets. So please consider that it’s cheaper and easier not to get towed, or to get tickets.
If there is ambiguity as to whether you may park somewhere or not, perhaps better to park somewhere else. Somewhere you know for certain you are allowed to park for the duration of your activity. Mahalo
