Ordered that the order is affirmed, with costs.
"The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicles and the traffic upon and the condition of the highway" (Vehicle and Traffic Law § 1129 [a]; see Carhuayano v J R Hacking, 28 AD3d 413; David v New York City Bd. of Educ., 19 AD3d 639). At the same time, the lead vehicle has a duty "not to stop suddenly or slow down without proper signaling so as to avoid a collision" ( Purcell v Axelsen, 286 AD2d 379, 380 [internal quotation marks omitted]; see Carhuayano v J R Hacking, supra).
Meagan A. Dixon, who operated the lead vehicle in a multi-vehicle collision, and Eleanor M. Dixon, who owned that vehicle, submitted evidence of a rear-end collision sufficient to establish their entitlement to judgment as a matter of law ( see Neidereger v Misuraca, 27 AD3d 537; Rainford v Sung S. Han, 18 AD3d 638; Malone v Morillo, 6 AD3d 324 ). However, the papers submitted in opposition to the motion were sufficient to raise a triable issue of fact as to whether Meagan A. Dixon contributed to the accident by making a sudden and unexplained stop ( see Taveras v Amir, 24 AD3d 655; Gaeta v Carter, 6 AD3d 576; Chepel v Meyers, 306 AD2d 235).
