An issue that frequently arises in the context of insurance coverage cases involves the definition and application of the phrase "use or operation"—a phrase that appears in several statutes pertaining to motor vehicles,[1] as well as in many insurance policies—most notably, the coverage sections of automobile liability insurance policies, and the exclusionary provisions of homeowners' policies.[2] The recent appellate decision in Nationwide Mutual Ins. Co. v. Oster, 193 A.D.3d 951 (2d Dept. April 21, 2021), has brought this issue into focus once again, this time appearing to expand the meaning and breadth of the phrase beyond all prior limitations.
