The bonus rules in the NBA take effect on the 5th team foul in each quarter.
In an NBA game quarter, the bonus rules take effect on the team's 5th foul. This means that once a team commits 5 fouls within a quarter, the opposing team will be awarded free throws for every subsequent foul committed by the fouling team. These free throws are commonly referred to as "bonus free throws" or "free throws in the bonus." The number of free throws awarded depends on the type of foul and the number of fouls that have been committed.
