This article shall apply only to driveways constructed after May 3, 1993 and to lawfully existing driveways changed after that date to connect with or serve one or more additional lots.
C. 
It is the intent to permit adjoining lots to share a driveway, the shared part of which is subject to precautions to ensure that the driveway will be maintained and remain useful for both ordinary and emergency access under all weather conditions, and to ensure that a driveway will not be used as a substitute for a street or as a substitute for mandatory access frontage. After May 3, 1993, a driveway may be constructed or extended to serve more than two lots only in accordance with a special permit authorized by the Planning Board, subject to all applicable provisions of this Bylaw.

A. 
The driveway shall lie entirely within the lots being served.

A shared driveway shall be considered satisfactory only if (1) it has been constructed in accordance with the provisions of the special permit; and (2) there is a recorded clear provision for maintenance and snow removal; running with the land.
C. 
A driveway shall not be used to provide the lot access frontage required by this Bylaw or by the Subdivision Control Law.
D. 
Where the access to structures or uses provided by the driveway is substantially different than that which would be provided through required lot frontages, the special permit shall not be issued unless the Planning Board finds that the proposed shared driveway and its location are in the public interest.
E. 
Where it is in the public interest, the special permit granting authority may require the owners to name the shared driveway and provide a number for each dwelling served by it. In the event that a sign is installed, it shall be subject to the approval of the SPGA.
F. 
The Planning Board shall submit a copy of the special permit and approved plan to the Building Commissioner. No building permit shall issue until receipt of the special permit and plan.
