An East Hampton man was charged with misdemeanor drunken driving in Springs shortly before 3 a.m. yesterday after crashing a sport utility vehicle into a tree, seriously injuring his passenger.According to East Hampton Town police, Mark M. Wesnofske, 37, lost control of his 2002 Land Rover on Three Mile Harbor Road near Squaw Road, veering across the road and into the woods. Mr. Wesnofske was able to climb out of the vehicle on his own, but his passenger, Emma Pittman, 30, had to be extricated, said Darrin Downs, second assistant chief of the Springs Fire Department. The fire department’s ambulance personnel treated her at the scene and took her to East Hampton Airport to meet a Suffolk medevac helicopter, which airlifted her to Stony Brook University Hospital.Meanwhile, a Springs ambulance took Mr. Wesnofske to Southampton Hospital to be treated for a head injury. After his release to police he was freed on an appearance ticket for arraignment in East Hampton Town Justice Court. The Land Rover was impounded for a safety inspection. Police continue to investigate, and have asked anyone with information about the accident to call 631-537-7575.In addition to that arrest and two more in which Leandra’s Law was invoked, reported elsewhere on this page, seven other people were charged with driving while intoxicated on East Hampton Town roads this week.One, Angel C. Deleg-Tenecota, 34, of East Hampton, faces a felony charge, having pleaded guilty last year to misdemeanor D.W.I. after being found asleep behind the wheel at a gas pump at the former Hess station in Wainscott. Early Saturday morning, police said, his 2015 Toyota was in an accident in the parking lot at Club Leo on Three Mile Harbor Road, police said, and he was ultimately charged. Bail was set later that morning at $5,000, which was posted.Felecia Mais of Springs, 27, was driving a 2001 Subaru on Three Mile Harbor Road in Springs Monday night when she swerved onto the shoulder and into a tree. Her station-house breath test reportedly produced a reading of .14 of 1 percent.During her arraignment Tuesday, East Hampton Town Justice Steven Tekulsky said that Ms. Mais did not have a driver’s license, only a learner’s permit. “You are not eligible for a hardship license,” he said. She was released after posting $250 bail.In Sag Harbor early Saturday morning, police received a call that a Jeep had hopped a curb on Madison Street, mowed down some shrubs, and driven away. An officer spotted the 2015 Jeep, with Jennifer C. Post, 58, at the wheel, standing still at the intersection of Madison Street and Jermain Avenue, “with extensive front-end damage.” The driver failed roadside sobriety tests, police said, and was taken to headquarters, where a breath test was said to have produced a .12 reading.Ms. Post, who was charged with leaving the scene of an accident as well as D.W.I., was released later that morning without bail.Sag Harbor police also arrested Le’Anne Moreau, 35, early last Thursday morning after receiving a report of a Nissan Altima being driven erratically north on Hampton Road. An officer spotted the car swerving across lane lines as it crossed the North Haven Bridge and pulled it over. Back at headquarters, Ms. Moreau refused to consent to the breath test, resulting in the automatic suspension of her New York State driving privileges. Though her driver’s license was issued in Lafayette, La., she has a Manhattan address as well as local connections, and was released without bail.Bradley C. Walsh, 43, of Manhattan, was stopped on Old Montauk Highway in Montauk Friday night after an officer saw his 2000 Jeep swerve onto the shoulder of the narrow road. At his arraignment the next morning, Justice Tekulsky noted that he had been convicted of driving while ability impaired, but at the violation level, meaning that the new charge is still a misdemeanor. Mr. Walsh, who told the court he was visiting Montauk for the weekend, posted $1,000 bail.Felipe Marin of Montauk, 25, was pulled over in a 2015 Toyota on West Lake Drive, Montauk, early Friday. His breath test came in at slightly over the .08 mark that defines intoxication, police said. He too has a prior ability-impaired conviction, and bail was set at $1,000, which was posted. His lawyer, Edison Bolivar, applied for and obtained a hardship license that will allow Mr. Marin to continue to drive to and from work.Roberta A. Newman, 57, of New Rochelle, N.Y., was arrested during the overnight hours on Monday. Her breath test came back at .14, police said, and she was freed on $250 bail with a future date on the fall’s crowded criminal calendar.Southampton Town police, working with the Suffolk County Sheriff’s Department, conducted a sweep in Bridgehampton Saturday night designed to get drunken drivers off the road. It began at 8 p.m. with saturation-style patrols, which ran until 10:30, when police switched to manning a checkpoint on Main Street in Bridgehampton, the township’s easternmost hamlet.
