What is the signal for an indirect free kick?

The signal for an indirect free kick is indicated by the referee raising one arm above their head, with the hand at a right angle to the arm. This gesture clearly communicates to players, coaches, and spectators that an indirect free kick has been awarded. The raised arm remains elevated until the ball has been kicked and has touched another player, ensuring that everyone is aware of the situation on the field.

This signal is vital as it distinguishes an indirect free kick from a direct free kick, the latter of which does not have the same signaling requirement. The other choices do not correctly represent the method of signaling an indirect free kick as per the laws of the game. Therefore, it is essential for referees to consistently use the correct signal not only for clarity but also for maintaining the integrity of the match.
