What signal does a referee give for an indirect free kick?

The signal for an indirect free kick involves the referee raising one arm above their head. This action is intended to inform players, officials, and spectators that the kick is indirect, meaning that the ball must touch another player before a goal can be scored. The raised arm must be maintained until the kick is taken and the ball is in play. This clear and visible signal helps to ensure that everyone on the field understands the nature of the restart and can prepare accordingly.
