The second caller told police that the vehicle ran off the roadway and struck an embankment on Middlesex Road near Colony Road in Darien, authorities said.
Police said officers located the driver, identified as 44-year-old Laura Gallo-Swimm, of New Canaan, in the vehicle.
Authorities said Gallo-Swimm smelled of an alcoholic beverage.

She was released on a $250 bond and is scheduled to appear in court on Monday, Dec. 13, police said.
