What does a direct free kick signal from the referee involve?

A direct free kick signal from the referee is indicated by raising one arm straight up with the palm open. This signal communicates to players and spectators that a direct free kick has been awarded to a team following a foul committed by the opposing team. The raised arm serves as a clear visual cue indicating that play will be restarted and that the team receiving the kick can attempt to score directly from that position without any additional touches needed.

In contrast to this signal, other gestures such as both arms extended sideways may indicate a different action like a corner kick or throw-in, while one arm down with a clenched fist is often used to signal a stop in play or an indirect free kick. Both hands on the hips doesn't correspond to a specific kick signal on the field, thus making it less effective in communicating an important decision like a direct free kick.
