What is “stacking” and does it apply to Massachusetts UM/UIM coverage?
“Stacking” refers to the situation where an injury victim combines UM/UIM coverage limits across auto insurance policies covering individual vehicles or within an insurance policy covering multiple vehicles. Massachusetts does not allow stacking of UM/UIM coverage (M.G.L.A. 175 §113L).
