DECISION ORDER
ORDERED that the order is reversed insofar as appealed from, on the law, with costs, and the motion is granted.
This action arises from a collision in which an ambulance owned by the defendant Richmond County Ambulance Service, Inc., and operated by the defendant Joshua F. Henry rear-ended a car driven by the plaintiff which was stopped at an intersection while waiting to make a left turn. Henry, who had been following the plaintiff's car and had been keeping a distance of two car-lengths behind it, testified at his examination before trial that he observed the plaintiff's signal and brake lights before the collision. However, when he applied his brakes the ambulance skidded on the wet roadway and struck the rear of the plaintiff's car. The Supreme Court denied the plaintiff's motion for summary judgment, finding an issue of fact as to whether the accident was caused by a sudden stop by the plaintiff's vehicle and the unavoidable skidding of the ambulance. We reverse.
It is well settled that a rear-end collision with a stopped vehicle establishes a prima facie case of negligence on the part of the driver of the moving vehicle, requiring the operator of that vehicle to come forward with a non-negligent explanation for the accident (see, Leal v. Wolff, 224 A.D.2d 392). Conclusory assertions of a sudden and unexpected stop are insufficient to rebut the inference of negligence (see, Levine v. Taylor, 268 A.D.2d 566; Corbly v. Butler, 226 A.D.2d 418; Benyarko v. Avis Rent A Car Sys., 162 A.D.2d 572; Young v. City of New York, 113 A.D.2d 833). Moreover, vehicle stops which are foreseeable under the prevailing traffic conditions, even if sudden and frequent, must be anticipated by the driver who follows, since he or she is under a duty to maintain a safe distance between his or her car and the car ahead (see, Vehicle and Traffic Law § 1129[a]; Levine v. Taylor, supra; Mascitti v. Greene, 250 A.D.2d 821; Leal v. Wolff, supra; Barba v. Best Sec. Corp., 235 A.D.2d 381; Cohen v. Terranella, 112 A.D.2d 264).
Both the plaintiff and the ambulance passenger testified that the plaintiff had stopped at the intersection for a full 20 to 30 seconds before the defendant`s ambulance collided with her car. Henry was aware that the plaintiff had stopped to make a left turn. Under these circumstances, the defendants' conclusory assertion that the plaintiff made a sudden stop is insufficient to raise a triable issue of fact (see, Dwyer v. Cohen, 262 A.D.2d 600; Johnson v. Phillips, 261 A.D.2d 269), as is the defendants' assertion that the ambulance skidded on a wet road surface (see, Hurley v. Cavitolo, 239 A.D.2d 559; Pincus v. Cohen, 198 A.D.2d 405). Accordingly, summary judgment should have been awarded to the plaintiff on the issue of liability.
