Double Dribble: foul; if a player stops dribbling and then starts again. A dribble comes to an end when a player: Touches the ball with both hands; Permits the ball to come to rest while he is still in control of it; Tries for a shot; Throws a pass; Touches the ball more than once before it touches the floor; Loses control of the ball; or Allows the ball to become dead. A player cannot dribble the ball again until after another player has touched the ball.
