Video Assistant Referees (VAR) are officials who assist the on-field referee by reviewing video footage of key moments during a match. Their main purpose is to ensure that crucial decisions, such as goals, penalties, and red cards, are accurate. VAR operates from a remote location, using multiple camera angles to analyze incidents. When a potential error occurs, the on-field referee can consult with the VAR team. The VAR can recommend a review or inform the referee of a clear mistake. This system aims to improve fairness and accuracy in sports like soccer and has been implemented in various leagues and tournaments worldwide.
