It was a two-for-one bust for Suffolk County cops yesterday — as they pulled two drunken drivers from the same car.

Jeff Gay, 23, was stopped on Lowndes Avenue in Huntington Station for allegedly driving erratically at about 2:45 a.m.

Then, while Gay was undergoing field-sobriety tests, passenger Jason Butler, 22, slid into the driver’s seat and zoomed off, police said. He didn’t get far before he was pulled over and charged with DWI, resisting arrest and obstructing governmental administration.

Gay, also of Huntington Station, was just charged with DWI.
