What does a red light signify when judging a powerlifting lift?

In powerlifting, a red light during a lift signifies that the attempt was not successful. This decision is made by the referees based on specific criteria that the lift must meet to be considered valid. When a lifter fails to meet the requirements, which may include improper form, not achieving the required depth in a squat, or failing to lock out during a bench press or deadlift, a red light is illuminated.

This visual cue is crucial for both the lifter and the audience, as it communicates the result of the attempt clearly and swiftly. Understanding the meaning behind the red light is essential for lifters and coaches alike, as it indicates that they need to reassess their technique or approach for future attempts.
