If the past week was any indication, drivers will need to be especially watchful on local roads this summer. The week saw 11 arraignments in East Hampton Town Justice Court involving defendants charged with driving while intoxicated.Three of the arrests occurred between Friday night and early Saturday. One involved a teenager; police have not released details in that case as yet. The others charged, both from Sag Harbor, were MariAlice Bennett, 29, and Luis A. Alvarracin, 32.Ms. Bennett was pulled over, reportedly for speeding, on Further Lane in East Hampton, and taken back to East Hampton Town police headquarters in Wainscott, where her breath test was recorded at over .18 of 1 percent, triggering a charge of aggravated drunken driving charge.Mr. Alvarracin’s 2004 Ford pickup was swerving across lane lines, police said, when they stopped it on Stephen Hand’s Path in East Hampton; he was hit with an additional charge of unlicensed driving. Both drivers were released Saturday morning without bail.Town police arrested Wilson Patricio Jara-Munoz, 38, and Brian K. Marciniak, 29, early Sunday morning. Both their breath tests produced readings of .19, police said. Each man posted the $500 bail set by Justice Lisa R. Rana later that morning.East Hampton Village police also brought a defendant to court on Sunday, a man who had allegedly produced an even higher number, .20. At a little after midnight Saturday, Arnold Rivas-Ovalle, 20, was said to have been riding a motorcycle, sans helmet, and to have driven up onto on the sidewalk and into the Blue Parrot parking lot, failing to signal a turn, after police activated their lights. He, too, was freed after posting $500 bail.On Monday night village police made a second D.W.I. arrest, this time on North Main Street just across from their Cedar Street headquarters. Adele Robin Filasky, 64, who was driving a 2016 Ford Focus with the taillights out, according to the report, was released Tuesday morning without bail.Jose A. Padilla-Deleg of Springs was arrested Sunday night. His charges were the most serious of the week, due to his having a previous drunken-driving conviction, in 2012. That made the new charge a felony.“You just got off probation,” Justice Rana said. She reminded the defendant that she had handled his prior case as she set bail at $5,000, which was posted.Mohammed S. Farooq, 27, of Bay Shore, who told Justice Rana he was a software designer for I.B.M., was charged Monday morning after being pulled over on West Lake Drive in Montauk; he reportedly refused the breath test at headquarters. He was released after posting $300 bail.Brian Ordonez-Alvarracin, 20, of East Hampton was the last to be arraigned this week. He was released without bail, but, like the others, with a future date on the court’s criminal calendar.Earlier in the month, on the morning of June 8, town police stopped Luis Fernando Vargas-Carrero, 20, of Montauk, saying his 2002 Nissan had been moving at 50 miles per hour on the hamlet’s Main Street, 20 over the limit. His blood-alcohol reading was among the week’s lowest, and he was released without bail.
