In basketball, a common violation is the most minor class of illegal action. Most violations are committed by the team with possession of the ball, when a player mishandles the ball or makes an illegal move. The typical penalty for a violation is loss of the ball to the other team. This is one type of turnover.
Common violations are defined in Rule No. 10 of the NBA Rulebook.
