SECTION 1. Chapter 140 of the Massachusetts General Laws shall be amended by inserting the following new section;

Section 131Z: Notwithstanding any general, special law or regulation to the contrary any person, not being a resident of the Commonwealth, who is not otherwise prohibited under federal law from transporting, shipping, or receiving a weapon shall be entitled to transport a weapon for any lawful purpose from any place where he or she may lawfully possess and carry such weapon to any other place where he may lawfully possess and carry such weapon. 

During such transportation the weapon shall be unloaded.  Neither the weapon nor any ammunition being transported shall be readily accessible or directly accessible from the passenger compartment of such transporting vehicle: Provided, that in the case of a vehicle without a compartment separate from the driver’s compartment the weapon and ammunition shall be contained in a locked container other than the glove compartment or console.

If a person is found to be in compliance and exempt under this section no persons or property shall be detained, held or confiscated unless an arrestable offense exists outside of the parameters of this section.

If a person who is exempt under this section is unexpectedly delayed in their travel including but no limited to mechanical, weather, illness, flight or other commercial travel delays such person shall retain the protections of this section.
