A ball is considered driven off the table if it comes to rest other than on the playing surface but is not pocketed. A ball is also considered driven off the table if it would have been driven off the table except for striking an object such as a light fixture, piece of chalk or a player which causes it to return to the table.
A ball that contacts the top of the rail is not considered to have been driven off the table if it returns to the playing surface or enters a pocket.
