A three-vehicle pileup on Montauk Highway in Wainscott sent two people to Southampton Hospital on July 25. The accident occurred in the westbound lane at around 12:15 p.m., in front of the Wainscott Village Shopping Center. East Hampton Town police said a Hampton Elite Swimming Pools utility truck ran into a 2014 Subaru Forester, which then rear-ended a school bus. There were no children in the bus at the time. The entire back window of the Subaru was shattered. Both the driver, Maude M. Muto, 56, of East Hampton, and her passenger, Molly Cangiolosi, 14, complained of neck pain and were taken to Southampton Hospital by a Bridgehampton Fire Department ambulance. The drivers of the utility truck and the school bus were not injured. The driver of the Moriches-based utility truck, Robert Distefano of that village, 58, was charged with operation of an unregistered vehicle. At around 5:45 p.m. last Thursday, a two-car accident occurred at the intersection of Swamp Road and Route 114 in East Hampton. Vivian Bell, 83, of East Hampton, driving a 2014 Hyundai, was northbound on Route 114 when she attempted to pass a vehicle ahead of her that was stopped to make a left turn. She told police she did not see Todd Richter’s oncoming 2004 Jeep, which was turning left onto Swamp Road. The Hyundai hit the rear passenger side of the Jeep. Ms. Bell complained of lower arm pain but refused medical attention. Neither driver was charged. On Saturday there was a rear-end collision on Montauk Highway in Montauk, near South Emery Street. At around 6:30 p.m., a 2013 Chevrolet Suburban hit the back of a 2017 Honda Suburban driven by Annette L. Powers, 44, of Brooklyn. She had four passengers, one of whom, Jessica Olich, 42, who was seated in back, complained of possible whiplash. She was treated by Montauk E.M.T.s at the scene and declined further medical attention. Ms. Powers told police she was slowing in traffic when the Suburban, driven by Krishna Lovish, 24, of Shirley, hit her car. Mr. Lovish said he could not stop in time to avoid the collision. Yet another rear-ender happened at around 2:30 a.m. Saturday on the Napeague stretch near Dolphin Drive. Christopher Stewart of Bay Shore, 28, with five passengers in his 2001 Honda van, was westbound, waiting to turn left into a private driveway, when a 2012 Nissan driven by Nicolas A. Orozco of Manhattan, also 28, ran into his car. All five passengers, three of whom declined medical attention, complained of neck or back pain. The other two — Danielle Kronfeld, 30, and Melissa Landry, 29, both of whom were sitting in back — were taken by the Amagansett ambulance squad to Southampton Hospital, where they were treated and released. Neither driver was hurt. On Sunday morning, again on Napeague, a 21-year-old hit a telephone pole and a residential sign near Napeague Meadow Road. Brandon J. Barnes of Commack told police he might have fallen asleep at the wheel. His vehicle’s airbags deployed upon impact. He was wearing his seatbelt when that happened, and was taken to the hospital to be treated for lower arm pain and minor bleeding. On Friday at around 1 p.m., a three-vehicle accident at the tricky intersection of Stephen Hand’s Path and Two Holes of Water Road in East Hampton sent one driver to the hospital. Police said a 1998 Chevrolet pickup truck heading west had failed to yield the right-of-way at a stop sign, causing the accident. Its driver, Jamie N. Vasquez, 41, of Hampton Bays, told police he was turning left when he collided with a 2004 Volkswagen. Its driver, Simone A. Martell of East Hampton, 45, said she was passing another car that was making a left onto Long Lane when it happened. Both the truck and the Volkswagen then struck a third vehicle, driven by David Samot, 54, who reported seeing Mr. Vasquez’s vehicle cut across the intersection and hit Ms. Martell’s. Ms. Martell’s airbags deployed and she was taken to the hospital complaining of pain. Mr. Vasquez was charged with unlicensed driving, making an improper U-turn, failure to yield the right of way, and failure to signal.
