VAR (Video Assistant Referee) is a match official who uses video replays to help the on-field referee correct clear and obvious errors in four specific, game-changing situations: goals, penalty decisions, direct red cards, and mistaken identity. Introduced into the IFAB Laws of the Game and used at competitions including the FIFA World Cup, VAR does not re-referee the match. It steps in only when the video shows the original decision was wrong or a serious incident was missed, and the referee always keeps the final say.
What VAR actually does
The VAR is a qualified referee who works away from the pitch in a video operation room, supported by assistant VARs and replay operators. They watch a live feed with access to every broadcast camera angle. On a goal or major incident, the VAR runs a quick, silent “check” in the background. If nothing looks wrong, play simply continues. If the footage suggests a mistake, the VAR recommends a review to the referee.
The guiding principle is “minimum interference, maximum benefit.” VAR is designed to catch match-changing mistakes, not to police every marginal contact. That is why the standard for intervention is a clear and obvious error or a serious missed incident, rather than a difference of opinion.
The four reviewable categories
Under the IFAB VAR Protocol, VAR can be used in only four types of decision. Everything else on the field is outside its scope.
| Category | What can be checked |
|---|---|
| Goal / no goal | Offside, handball, fouls or the ball out of play in the build-up, and offences during a penalty kick |
| Penalty / no penalty | Whether a penalty was correctly awarded or wrongly missed, and the location of the offence |
| Direct red card | Serious foul play, violent conduct, denying an obvious goal-scoring opportunity, biting or spitting (not second yellow cards) |
| Mistaken identity | When the referee cautions or sends off the wrong player |
Note that a second yellow card leading to a sending-off is not reviewable, because it falls outside these four categories. Similarly, a foul in midfield that leads to nothing is never checked.
How a review works
There are two ways VAR can influence a decision. In the first, the VAR simply relays factual information the referee could not see, such as an offside position or the exact point of contact. In the second, for more subjective judgments, the VAR recommends an on-field review. The referee signals a rectangle with both hands, walks to the pitchside monitor, watches the replay, and then makes the call.
Factual matters such as offside or whether the ball crossed the line tend to be decided quickly by the VAR without an on-field review. Judgment calls, such as the severity of a challenge or whether an incident is a red-card offence, usually send the referee to the screen so the decision remains visibly theirs.
Crucially, the check itself does not stop the game unless the ball is already out of play or the referee halts it. If a possible offence is spotted, play often continues until a natural stoppage, at which point the review takes place and, if needed, the decision is corrected retroactively to the moment of the incident.
Where VAR is used
VAR was written into the IFAB Laws of the Game after a period of live trials and is now used in many top competitions, including the FIFA World Cup, major continental tournaments, and numerous domestic leagues. It is not mandatory everywhere, however. Running VAR requires cameras, technology, a video operation room, and trained officials, so many lower divisions and smaller competitions operate without it. This is why a decision reviewed in a top-flight match might stand uncorrected in a lower league playing under the same laws.
Some competitions also use supporting technology alongside VAR, such as goal-line technology to confirm whether the ball crossed the line and semi-automated systems to speed up tight offside checks. These tools feed information to the officials but do not replace the human judgment at the heart of the protocol.
What VAR does not do
VAR cannot invent new decisions outside its four categories, and it cannot overturn a call simply because a different referee might have seen it another way. It also does not change how offside or handball are defined; it only helps apply those existing laws more accurately. Decisions such as corner-versus-goal-kick, throw-in direction, or a routine free kick are never reviewed.
Because of this narrow remit, plenty of debatable moments still go unchecked. VAR is a safety net for the biggest mistakes, not a guarantee that every decision will please everyone.
Why VAR matters
The clearest impact of VAR is on the game’s most consequential moments. A wrongly disallowed goal, a penalty kick given for a dive, or a red card shown after a serious missed foul can decide a title or a tournament. By reviewing exactly these situations, VAR aims to make sure results turn on what actually happened.
It also affects discipline. A red card for violent conduct that the referee missed can be issued after a review, and a card shown to the wrong player can be corrected. These outcomes protect both fairness and player safety.
VAR remains one of soccer’s most debated innovations. Supporters value the added accuracy on decisive calls, while critics point to delays and the loss of spontaneous celebrations. What is not in dispute is the framework: a video official, four reviewable categories, a strict error threshold, and a referee who still makes the final decision.
Frequently asked questions
What does VAR stand for?
VAR stands for Video Assistant Referee. It refers both to the video review system and to the assistant referee who operates it from a video operation room. The official uses replay footage to help the on-field referee correct serious mistakes.
What are the four things VAR can review?
VAR can review only four categories of decision under the IFAB protocol: goals and the build-up to them, penalty decisions, direct red cards, and cases of mistaken identity. Anything outside these four situations is not reviewable, even if a mistake occurs.
Can VAR overrule the referee?
No. VAR only advises. The referee on the pitch remains the ultimate decision-maker and can accept the VAR’s information or view the footage personally at the pitchside monitor. The final call always belongs to the referee.
What is an on-field review?
An on-field review (OFR) is when the referee walks to a pitchside monitor to watch the replay before making a decision. It is used for subjective calls, such as whether a challenge is a penalty or a red-card foul.
Why does VAR take so long?
A review can take time because officials check multiple camera angles for accuracy, particularly for tight offside calls involving lines drawn on the pitch. The threshold is a clear and obvious error, so officials only intervene when the footage shows the original decision was wrong.
Does VAR check every goal?
VAR performs a silent check on every goal for offside, handball, fouls, or the ball leaving play in the build-up. Most checks take seconds and confirm the goal, so play resumes without any visible review or delay.
