Answer
No, all decals are repositionable and created specifically to be moved from vehicle to vehicle as needed. Whether carpooling or switching vehicles between significant others, roommates, or family members you will only need one decal. Multiple vehicle profiles can be added in JayPark, but the decal is required for whatever vehicle is on campus property. A second decal will not be given.
If a second decal is needed because two vehicle will be parked at the same time, it will need to be approved in person by parking services on a case-by-case basis and is not guaranteed. If approved the decal must be purchased for the current full price in office via a credit/debit card or cash.
