It is undisputed that the bus involved in this accident, was owned by the County of Westchester. Accordingly, plaintiffs' failure to serve a notice of claim requires dismissal ( see, General Municipal Law § 50-b; Coleman v. Westchester St. Transp. Co., 57 N.Y.2d 734; James v. Liberty Lines, 97 A.D.2d 749). Titone, J.P., O'Connor, Lawrence and Eiber, JJ., concur.
