In
basketball,
traveling is a
moving violation in which someone moves both feet without
dribbling the ball. It is legal to move one foot (called a
pivot), and in professional basketball often it is overlooked when used as a
precursor to
dunking, just because the masses are watching basketball to have fun, not to make sure that all the rules are followed
precisely.
When a player is caught traveling, the ball is turned over to the opposing team, and one of their players takes it out of bounds.
