An Edgartown woman was charged with drunken driving Friday after a single car crash left the car submerged in the water by the big bridge in Oak Bluffs.

Ashley Peters, 22, was charged with drunken driving, negligent operation of a motor vehicle, marked lanes violation and speeding in the crash at 12:50 a.m. Friday, state police Sgt. Thomas Medeiros said.

Ms. Peters, who was driving toward Edgartown on Beach Road, veered to the right just before the big bridge and into the water, Sgt. Medeiros said.

She was helped out of the car by a nearby fisherman, Robert Jacobs, 64, of Oak Bluffs, Sgt. Medeiros said. The car became submerged and began to float to the middle of the channel.

Ms. Peters was taken to the hospital and placed under arrest. She was treated, released and taken to the house of correction, where she was released on bail.

Sgt. Medeiros said that Oak Bluffs police, fire and rescue, Edgartown police and state police responded to the scene.

The Oak Bluffs dive team and a tow truck removed the car from the water, he said.
