IRP Delete Vehicles IRP Delete Vehicles Important Notes: Deleted vehicle supplements remain in a $0 invoiced status. This allows for transfer of the plate to a replacement vehicle during the current registration period. If a deleted vehicle supplement is left in $0 invoiced status for more than 30 days, it will cause the account to lock. Need your account unlocked? When you are ready to transfer a plate to a replacement vehicle, send a request to place the vehicle on the account and complete the transfer plate supplement.
