A man was rescued from a car that went into the Potomac River on Tuesday night, the Arlington County Fire Department said.

Two cars apparently left George Washington Memorial Parkway and went into the water between the 14th Street and Memorial bridges, about 8 p.m., said Taylor Blunt, a spokesman for the fire department.

Rescuers broke a window to help the driver get out of one of the cars after it became partially submerged offshore near Lady Bird Johnson Park, Blunt said.

The other car was fully beneath the surface when rescuers arrived. Its driver had apparently freed himself and swam to shore, Blunt said.

Both drivers were reported to be in stable condition, authorities said.

It was not immediately clear why the vehicles left the roadway.
