Impact on Reciprocity Agreements
(1) The Plan is the registration reciprocity agreement applicable to all apportionable vehicles
notwithstanding the existence of any prior reciprocity agreements or arrangements between the
Commonwealth and any other state or Canadian province. To the extent a conflict exists
between the provisions of any such other reciprocity agreements or arrangements, or any
provision of M.G.L. c. 90 dealing with the registration of vehicles or the operation on the ways
of the Commonwealth of vehicles registered in other Plan member jurisdictions, the terms of the
Plan shall prevail.
