Except where adjacent buildings, structures, or lots are served by the same driveway openings, each building, structure, or lot shall be provided with two driveway openings onto the street, one of which shall be used for entrance to, and the other for exit from, the building, structure, or lot. Not more than two such openings shall be permitted for each 200 feet of street frontage. Such openings shall be not more than 20 feet in width at the street lot line and located no less than 40 feet apart, measured along said line, and not less than 20 feet from side lot lines. Where approval by the MassDOT is required in connection with driveway openings onto state highways, the prior provisions of this §
198-1002.1.3 shall be waived, and the regulations of MassDOT shall be applicable.
