Soccer 101: What Is VAR and how does it work?

What is VAR? Here’s what you should know before you watch World Cup matches.

DALLAS — Alright, you’re watching a soccer match – whether it be the World Cup, Major League Soccer or Premier League – and the action suddenly stops.

The referee touches an earpiece. Players wait. Fans grow restless. Then comes the announcement: VAR review.

And you might wonder: What the heck is VAR?

What is VAR?

VAR stands for Video Assistant Referee. It is a system designed to help on-field officials review certain plays and correct what are considered “clear and obvious errors.”

Think of it as soccer’s version of a booth review.

When is VAR used?

VAR is not meant to re-officiate every call. Instead, it is reserved for four specific situations:

Goals and potential violations in the buildup to a goal
Offside decisions
Potential red-card offenses
Cases of mistaken identity, such as penalizing the wrong player

If a questionable moment falls into one of those categories, the video assistant referee — located in a booth with access to multiple camera angles — reviews the play while the match is paused.

What happens during VAR check?

When a VAR check is underway, the referee on the field is in constant communication with the video official. In some cases, the referee will jog to a sideline monitor to conduct an on-field review, watching the replay personally before making a decision.

That image — the referee tracing a rectangle in the air with their hands — has become a familiar signal to fans worldwide.

Despite the technology, the head referee maintains final authority. VAR can recommend a review, but the on-field official makes the ultimate call.

VAR controversy: Why it matters

VAR was introduced to increase accuracy in high-stakes moments. The system aims to eliminate major mistakes that could change the outcome of a match, while still preserving the flow and human element of the game.

The next time play pauses and the referee reaches for an earpiece, you’ll know: It’s not random confusion. It’s a review process designed to ensure the right call is made when it matters most.
