What color card is issued for failing to lock the knees on a deadlift?

In powerlifting, the issuance of colored cards serves as a method for referees to indicate the type of fault or infraction committed by the lifter. When a lifter fails to lock their knees at the completion of a deadlift, this is considered a serious technical error. The knee locking signifies that the lift is fully completed, and without it, the lift is not valid.

A red card is specifically reserved for major infractions, which include failing to lock the knees. This card indicates that the lifter did not meet the technical requirements necessary for a successful lift, emphasizing the importance of proper form during competition. Other colored cards have different meanings—such as blue for minor faults—illustrating the severity of the infraction at hand. In this instance, a red card highlights the critical nature of executing the lift correctly, which is essential for both the safety of the athlete and the integrity of the competition.
