DECISION ORDER
ORDERED that the appeal from so much of the order as granted the motion of the third-party defendant Mack Trucks, Inc., is dismissed, as the plaintiff is not aggrieved by that portion of the order ( see CPLR 5511); and it is further
ORDERED that the order is affirmed insofar as reviewed; and it is further,
ORDERED that one bill of costs is awarded to the respondents.
The defendant third-party plaintiff, Leach Company (hereinafter Leach), made a prima facie showing of entitlement to judgment as a matter of law by demonstrating that any finding as to proximate cause would be based on mere speculation ( see Mazzone v. Lazaroff, 305 A.D.2d 558, 559; Johnson v. Sniffen, 265 A.D.2d 304; Scheer v. City of New York, 211 A.D.2d 778). In opposition, the plaintiffs failed to raise a triable issue of fact ( see generally Zuckerman v. City of New York, 49 N.Y.2d 557). Therefore, the Supreme Court properly granted Leach's motion for summary judgment dismissing the complaint.
