A. Registration of Vehicles Added to Fleets. Vehicles acquired by a registrant after the commencement of the registration year may be added to the proportionally registered fleet by applying the mileage percentage used in the original application for registration of the fleet for the registration period to the regular registration fees applicable to the additional vehicles for the remainder of the registration year. Applications for proportional registration of additional fleet vehicles shall be filed and processed in the same manner as the original application, using supplemental registration forms furnished by the Administration.
B. Withdrawal and Replacement of Vehicles from Fleets. The following shall apply to the withdrawal of a vehicle from a proportionally registered fleet:
(1) If a vehicle is withdrawn from a proportionally registered fleet during the period for which it is registered, the registrant shall so notify the Administration on the appropriate form.
(2) If the registrant replaces a vehicle for one withdrawn from the fleet the registrant shall file a supplemental application. The Administration will issue a new cab card and transfer the registration for the new vehicle. Additional proportional fees will be required for those jurisdictions that do not allow transfer credit.
(3) If a vehicle is permanently withdrawn from a proportionally registered fleet because it has been destroyed, sold, or otherwise completely removed from the service of the registrant, the fees paid with respect to the vehicle will be applied against registration fees which may be payable for additions to the fleet during the same registration year.
(4) If a vehicle of an apportioned fleet is withdrawn from the fleet, the vehicle cannot be returned to the fleet during the same registration year except upon payment of a proportional registration fee for the vehicle determined in accordance with §A, unless the vehicle was leased and the previous lease expired 30 days or more before the date of return to the fleet.
C. Increase in Registered Weight. The registered gross weight for a vehicle of a fleet may be increased after the commencement of the registration year by applying the mileage percentage used in the original application for registration of the fleet for the registration period to the difference between the regular registration fees for the current and the new weights for the remainder of the registration year. Application for a weight increase shall be filed and processed in the same manner as the original application, using supplemental registration forms furnished by the Administration.
