Four out of five people involved in auto accidents between last Thursday and Saturday were taken to Stony Brook Southampton Hospital by an East Hampton ambulance. A single-vehicle accident sent a 31-year-old driver there last Thursday. At around 10 a.m., East Hampton Town police said, Nelly E. Nieves-Tenecela of East Hampton, the driver of a 2002 Nissan, had been heading south on Swamp Road, south of Passing Road, when she apparently lost control of her vehicle while entering a curve and hit a tree. The airbags in the Nissan were deployed. However, Ms. Nieves-Tenecela complained of chest pain. She was charged with driving without a license. On Friday, a rear-ender on Springs-Fireplace Road near Abraham’s Path in East Hampton resulted in two drivers going to Stony Brook Southampton Hospital. At around 10:30 a.m., the driver of a 1998 Nissan, Neville F. Carr of East Hampton, 64, told East Hampton Town police that he was stopped facing north on Springs-Fireplace Road waiting to make a left turn into a parking lot when he was rear-ended by a 2001 Ford pickup truck, which appeared to be approaching at high speed. Mr. Carr complained of head pain. The driver of the truck, Wilson F. Ortega of East Hampton, 41, complained of lower leg pain. He was charged with following too closely, but he said Mr. Carr had stopped suddenly and that he had tried to avoid the collision. Later that day, a 17-year-old heading north on Alewife Brook Road in Northwest lost control of her 2007 Land Rover while turning right onto Cedar Point Road. Once on Cedar Point Road, she hit a stop sign and then a tree, causing the vehicle’s airbags to deploy. East Hampton Town police said India Naschke Attias of East Hampton, 17, the driver of the Land Rover, which was registered to Stacey N. Attias, complained of chest pain. Another rear-ender occurred Saturday at around 7 p.m. on Montauk Highway, just east of Town Line Road in Wainscott. Sergio Salazar of East Hampton, 63, told East Hampton Town police that he was traveling east on Montauk Highway when the vehicle in front of him stopped short, causing him to brake suddenly. As a result, the vehicle behind him, a 2011 Audi driven by Sarah May Brock of New York, 25, hit Mr. Salazar’s 2014 Mazda. Mr. Salazar, who was charged with driving an unregistered vehicle, complained of minor neck pain but refused medical attention. The driver of the Audi, Ms. Brock, was not injured.
