When do I need to get an official's attention?

Notify the nearer official when:

1. A team reaches the bonus (the opponent's fifth team foul in the quarter).
2. Any player is charged with a fifth foul (personal and technical combined).
3. Any team member or bench personnel gets a second technical foul, the head coach gets a second direct technical, or the head coach gets a third technical of any kind.
4. A team has been granted all its allotted timeouts, or an excess timeout.
5. The ball is dead, or in control of the offending team, and a player hasn't reported, has changed number, or is illegally in the game.
6. The ball is dead and there's a score dispute or doubt about an official's decision.
7. A player enters wearing an illegal number.
8. The ball is dead (clock stopped or running) and a coach asks for a correctable error, or a timing, scoring or alternating-possession mistake, to be fixed.

If you have any doubt about a call, signal as soon as conditions permit so the official can verify it.
