a) If a household goods carrier discontinues the use of a vehicle for which a current interstate cab card/Illinois interstate identifier has been executed and provides a newly-acquired vehicle as a substitute, the carrier can transfer the cab card/identifier by following the procedure in this subsection.

1. 1) The carrier shall execute a new interstate cab card identifying itself and the substitute vehicle and shall enter the appropriate expiration date on the cab card;
2. 2) The carrier shall enter the date on which it terminates use of the discontinued vehicle in the space for the early expiration date on the cab card; and
3. 3) The carrier shall permanently attach the upper left-hand corner of the cab card for the substitute vehicle to the upper left-hand corner of the cab card for the discontinued vehicle so as to permit inspection of the contents of both cards. At this point, the Illinois interstate identifier on the cab card of the discontinued vehicle shall apply to the substitute vehicle.
