This rule prohibits a defensive player from remaining in the free-throw lane for more than three consecutive seconds while not actively guarding an opponent. To be considered actively guarding, the defensive player must be within arms length of an offensive player. Violations result in a technical foul assessed against the offending team.
This regulation aims to prevent excessive clogging of the lane by defenders, promoting offensive opportunities and a more fluid game. Its introduction has historically contributed to spacing and increased scoring by reducing the dominance of inside-out defense. The rule enforces a dynamic game where defenders must actively engage with offensive players rather than simply camping near the basket.
