What Is A 3-Seconds Rule In Basketball?

Three-Second Rule In Basketball

A three-second violation in basketball is when a player spends more than three seconds inside the free-throw lane while not actively guarding an opponent. This is also called “camping” or “loitering”.

If a player does violate the three seconds rule, it is called a “lane violation.” The offending player will be given a warning if it is their first offense. If they commit another lane violation, they will be given a technical foul and will have to leave the game for five minutes.

Types Of Three-Second Rule

When it comes to the three-second rule, there are two different types: offensive and defensive.

The Offensive 3-Second Rule:

Offensive three-second violations occur when an offensive player spends more than three seconds in the key while the ball is not in their possession.

The Defensive 3-Second Rule:

Defensive three-second violations occur when a defensive player spends more than three seconds in the key while their opponent is shooting.

Offensive three-second violations are more common than defensive ones, as it is easier for an offensive player to stay in the key without the ball. If a player violates the offensive three-second rule, it results in a turnover.

Penalty For Three-Second Violations:

The penalty for a three-second violation is loss of possession. The rule was put in place to prevent players from “camping” or “loitering” inside the free throw lane, which would give them an unfair advantage on defense.
