After a tumultuous Memorial Day weekend, with multiple daily arrests for driving while intoxicated, the roads were noticeably calmer last week. Just three people were charged, all of them over the weekend.A little after midnight on Sunday, Ingrid Lukic, 32, was headed west on Montauk Highway in Wainscott near Sayre’s Path when she failed to dim the lights of her 2013 Fiat for an oncoming vehicle, which happened to be an East Hampton Town police car. A computer check revealed that her license had been suspended in Southampton two years ago for failure to answer a traffic matter, and she was taken to headquarters, police said, after failing roadside sobriety tests.Ms. Lukic, who lives in Westport, Conn., and spends summers in Bridgehampton, recorded a blood-alcohol reading of .18, according to police, high enough to raise the misdemeanor charge to the more serious aggravated level. While she was in custody police inventoried her personal effects and reportedly found a small quantity of cocaine in her purse, leading to a misdemeanor charge of drug possession as well.Seated in court Monday morning for her arraignment were three friends, who agreed to post the $250 bail amount set by East Hampton Town Justice Steven Tekulsky.Also arraigned on Monday was Boris F. Villa-Pintado, 30, of Bridgehampton. East Hampton Village police had received a call Sunday evening reporting a car being driven erratically on Newtown Lane. An officer spotted the car, a 2002 Mazda being driven on the shoulder of the street. Mr. Villa-Pintado’s breath test produced a reading of .19, police said, meaning that he too faces the elevated misdemeanor charge.Complicating his case is that unlike Ms. Lukic, whose license was suspended, he apparently never had a license to begin with. In such situations, Justice Tekulsky suspends defendants’ nonexistent driving privileges, as required by law, and warns them that if charged again and convicted of unlicensed driving, they will go to jail. He did so in this case, and set bail at $500.Mr. Villa-Pintado said he understood, and posted the amount.Arthur R. Arnold of Bethel, Conn., 52, was stopped for speeding early Sunday morning as he headed west out of downtown Montauk; police said they clocked his 2016 Chevrolet at 53 miles per hour in a 30 m.p.h. zone. His breath test produced a reading of .14, well over the .08 number that defines intoxication. Mr. Arnold told Justice Lisa R. Rana later that morning that he had been doing some contracting work in Montauk.He was released on $300 bail, with a future date on the court’s criminal calendar.
