Final answer:
A double dribble is a basketball violation that occurs when a player dribbles the ball, stops, and then begins dribbling again. This action is not allowed and leads to a turnover.
Step-by-step explanation:
If a player is dribbling, stops dribbling, and then starts dribbling again, this is called a double dribble. A double dribble is a violation in basketball. Once a player has stopped dribbling, they are not allowed to begin dribbling again with two hands or to dribble with the same hand after ceasing their dribble. Once the player picks up the ball, they must either pass it, shoot it, or otherwise move in compliance with the rules. Restarting the dribble is illegal and will result in a turnover, with the opposing team gaining possession of the ball.
