What Is VAR and How Does Video Assistant Referee Technology Work in Football?
Video Assistant Referee (VAR) technology is a video-based officiating system that assists on-field referees by reviewing critical decisions through multiple camera angles, reducing refereeing errors and promoting fairness in every match.
VAR assists referees by capturing live footage in a Video Operation Room (VOR), identifying potential “clear and obvious errors,” and communicating recommendations via headset to the on-field official. For example, offside goals are reviewed within seconds, ensuring accurate score validation.
A defined VAR protocol guides each review step-by-step before any decision alteration occurs. VAR improves refereeing accuracy and reinforces trust in match outcomes while laying the groundwork for understanding how reviewable incidents are managed.
What Is the Role of the VAR Team and Their Decision-Making Process?
The VAR team comprises three core roles—VAR, Assistant VAR (AVAR), and Replay Operator—each performing distinct tasks to ensure consistent decision-making and clear communication.
- VAR reviews live footage to detect potential errors.
- AVAR cross-checks footage and supports the VAR’s assessment.
- Replay Operator manages camera angles and replays for precise analysis.
These roles collaborate in the Video Operation Room using real-time data feeds. Each team member adheres to IFAB guidelines to uphold procedural integrity, ensuring that refereeing authority remains with the on-field official. Understanding the VAR team’s process prepares us to examine which incidents qualify for review.
Which Football Incidents Are Reviewed by VAR?
The table below outlines the four reviewable incident types under VAR protocol, showing how each incident is managed and why it matters.
Each incident triggers a structured replay sequence in the VOR, and only “clear and obvious errors” lead to overturning the original call. With this clarity, we can define the threshold that guides every VAR intervention.
How Does VAR Protocol Define Clear and Obvious Errors?
A clear and obvious error is defined as a factual mistake so indisputable that video evidence leaves no room for reasonable doubt.
