What is the correct color card for excessive movement of the feet during a squat?

In powerlifting, the use of colored cards serves as a method for referees to signal specific infractions during a lift. The color card associated with excessive movement of the feet during a squat is yellow. This movement is considered a minor infraction, indicating that while the lifter may still be completing the lift, there is a need for correction in their technique.

A yellow card serves as a caution to the lifter, notifying them that while their lift was considered valid, there is a specific area of their performance that could be improved. The goal of this system is to maintain fair competition and encourage lifters to adhere to proper form and technique, which is critical in ensuring safety and success in the sport.

Other colors have different meanings; for instance, a red card indicates a more serious infraction resulting in disqualification of the lift, while blue and black cards are not standard in the context of excessive foot movement. This specificity in color coding helps referees effectively communicate the nature of any rule violation.
