Scarborough Town Council Chairwoman Judith Roy had a blood alcohol content nearly twice the legal limit when she was pulled over by police earlier this month, according to a court document.

Roy, 68, faces two counts of drunken driving in the incident on Sept. 17.

The first count accuses her of having a blood alcohol content of 0.15 percent, an offense that carries a minimum mandatory jail sentence of 48 hours.

The second charge, of having a blood alcohol content of 0.08 percent or more, does not involve jail time. A $400 fine and a 90-day license suspension apply to both charges.

Her arraignment is scheduled for Nov. 2 at the Cumberland County courthouse. Roy’s lawyer, Matthew Nichols, indicated in a letter to the court clerk that he will appear on Roy’s behalf and enter a not-guilty plea. Nichols could not be reached for comment.

Roy was issued a summons charging her with driving under the influence on the night of Sept. 17.

Police said Roy was taken to the police station after she pulled into the driveway of her home on Second Avenue.

A motorist reported an erratic driver on Black Point Road around 10 p.m. and noted that the car’s body was damaged.

The motorist followed Roy and they intersected at Roy’s home with a police officer coming from the northern part of town, said Police Chief Robert Moulton.

Moulton would not describe the erratic driving.

He said he did not know what Roy had been doing or where she was coming from before she was stopped.

The next day, Roy and another person reported a “very minor” parking lot accident that happened on the day she was summonsed, Moulton said.

But the body damage observed by the motorist who reported Roy didn’t appear to be from that accident, Moulton said.

Roy has said she is evaluating whether she will remain on the Town Council.

She could not immediately be reached for comment Wednesday but previously apologized for her behavior.

Roy served on the council from 1990 to 1999. She was elected again in 2007 and won another three-year term last year.
