ANDOVER — A Tewksbury woman was arrested early yesterday morning on drunken driving and other charges after police said she was speeding down the breakdown lane of Interstate 93 South with two young children in the back of her car, one of whom was not in a child-safety seat.

Kristin A. Hartman, 40, of 912 Old Shawsheen St., has been charged with driving under the influence of liquor, two counts of driving under the influence while having a child under 14 in the vehicle, having a child under the age of 5 in the car unsecured, negligent operation of a motor vehicle and a breakdown lane violation.

She was arraigned in Lawrence District Court yesterday and released for a later court date.

Andover police Sgt. Patrick Robb said in his report that he was in his marked patrol cruiser on I-93 South near I-495 at about 2:15 a.m. when he observed a vehicle approaching from behind at a very high rate of speed.

He said it appeared that the car, a black Nissan Pathfinder, was going to take the exit ramp to 495 North as it swerved from the middle travel lane to the far right hand side of the road.

Instead, it continued to travel on 93 South in the breakdown lane, he said. He reported that he was going about 65 mph and estimated Hartman's vehicle was traveling about 95 mph.

He turned on his lights and the car pulled over after about three-quarters of a mile just prior to Route 133/Lowell Street in Andover.

As he was speaking with the operator, Robb observed two young children in the rear passenger area, one in a car seat, the other not secured.

After asking her a few questions, including where she was coming from, he said he detected a strong odor of alcohol on her breath, and asked if she had been drinking. Robb said she told him she'd been at a friend's house since 8 p.m. and had consumed six drinks.

She told him she needed to get her children home.

He said he conducted a field sobriety test, noticing as she got out of her car and nearly stumbled into the travel lane of 93, that she was unsteady on her feet and swayed as she walked. According to Robb, she failed every test he conducted, and at one point became belligerent, saying she was an attorney and calling him an expletive.

Hartman works for a Boston law firm, Bonner Kiernnan, according to the report.

She was then arrested and taken to the police station for booking, during which she "became unruly" and made threatening comments, pointing her finger at police officers and telling them she would be calling her "trooper friends," among other comments.

She refused to take the breathalyzer test, according to Lt.John Pathiakis.

The children — Hartman's two sons — were released to a family friend. Robb said he would be filing a report with the Department of Children and Families regarding the incident.
