Few things divide fans like the Video Assistant Referee. At the 2026 World Cup, VAR is once again part of every match, working behind the scenes to help the on-field referee get the big calls right. Here is what it actually does.
What VAR can review
VAR does not re-referee the whole game. It only looks at four types of match-changing decisions: goals and whether there was an infringement in the build-up, penalty decisions, direct red cards, and cases of mistaken identity when the referee books the wrong player. Everything else stays with the officials on the pitch.
How a review happens
The video team, watching multiple camera angles, flags a possible clear and obvious error and recommends a review. The referee can then check a pitchside monitor before making the final call, which always remains theirs. For tight offside calls, semi-automated technology tracks the ball and players to speed up the decision and reduce guesswork.
Why it matters
In a knockout tournament where one decision can end a nation's campaign, VAR is meant to cut out the clearest injustices, a wrongly allowed goal, a missed handball, a mistaken red card. It will never please everyone, but the aim is simple: fewer game-changing mistakes on the biggest stage.
