Section 250-162-9 - APPORTIONABLE VEHICLES (see Section 1 - Definitions)1. Apportionable vehicles must be registered in the IRP.2. A vehicle is determined to be apportionable according to the use and characteristics of the power unit or the power unit used in combination.3. The intent of the applicant or registrant to operate a vehicle in two or more member jurisdictions is to be considered as an objective fact, determined from all the circumstances of the particular case.4. The fact that a vehicle is not used in more than one jurisdiction for an entire registration year and for six additional months gives rise to the presumption that the registrant did not intend to operate in more than one member jurisdiction. The registrant may present information to overcome such presumption.29- 250 C.M.R. ch. 162, § 9
