The report did not state that there were any eyewitnesses to the accident nor that the plaintiffs had admitted that they failed to stop on a signal or light. The statements in the UF6B report that the plaintiffs failed to stop on signal and that the defendant driver was not guilty of any contributing violation were conclusions of the officer as to the cause of the accident which were prejudicial and which were not admissible as entries made in the regular course of business ( Lea v. Segreto, 23 A.D.2d 759; Coppola v. Melvin, 241 App. Div. 611; Needle v. New York Rys. Corp., 227 App. Div. 276; Skoller v. Short, 35 N.Y.S.2d 68; 5 Weinstein-Korn-Miller, N Y Civ.
