A woman who cops suspected of killing her twin sister after their car plummeted off a Hawaii cliff was arrested in upstate New York for drunk driving when she nearly hit a cop's car, police said.

Alexandria Duval, 37, was arrested Monday after she allegedly swerved out of her lane on State Route 23 in Delaware County, nearly striking a New York State Police investigator's vehicle, cops said.

Duval, who has family in the area, continued to swerve as she drove too close to another vehicle, officials said.

She was pulled over as she drove onto Main Street in the Village of Stamford, where a trooper discovered she was driving without wearing a seat belt.

Duval took a breathalyzer test, which revealed her blood alcohol content was 0.26, more than three times the legal limit, police said.

She refused to be fingerprinted, photographed or say where she lives, authorities said.

Duval was driving on Maui's Hana Highway with her twin sister Anastasia on May 29 when they slammed into a rock wall and drove off the road.

Duval’s Ford Explorer landed 200 feet below on a rocky shoreline, killing Anastasia after what witnesses described as a violent fight between the women before the crash.

Though investigators alleged Duval deliberately caused her sister’s death, a judge later ordered her release saying there was no probable cause for the second-degree murder charge for which she was jailed.

Prosecutors in Hawaii said they planned to search for further evidence in the case.

The twins did most things together — including running two successful Twin Power yoga studios in Palm Beach County, Florida from 2008 to 2014 — but were reportedly often at odds.

“They had a rage problem, an anger problem [and] were arrested several times with anger incidents involving even the police,” gossip columnist Jose Lambiet told Inside Edition at the time.

Duval was ordered held on $5,000 cash bail at Delaware County Jail after her arraignment in Stamford, where she remained Thursday.

She is due in court on August 23.
