What does "red light" indicate in a lift?

A "red light" in powerlifting signifies that the lift was unsuccessful and did not meet the required standards set by the referees. This signal is crucial as it communicates to the lifter and spectators that the attempt did not comply with one or more of the recognized rules for that particular lift. Common reasons for receiving a red light include improper technique, failure to follow commands, or not completing the lift within the defined parameters, such as depth in squats or lockout in bench presses.

The importance of this system lies in its role in maintaining fairness and safety during competitions, ensuring all lifters adhere to the same standards. Therefore, when a lifter sees a red light, they understand that the attempt has not met the necessary criteria for a valid lift.
