What is the process for calling off a jam in roller derby?

Tapping their hands on their hips twice is the correct method for a jammer to signal the end of a jam. This action is recognized by officials, teammates, and opponents as a clear indication that the jammer wants the jam to be called off. It is essential for communication during the fast-paced game, as verbal cues can often be lost amidst the noise of the crowd and the action on the track.

Understanding this method is key, as it ensures that all parties involved recognize the intention to stop the jam and maintain the flow of the game. Quick and clear communication is vital in roller derby, where timing can affect scoring and strategy. Other options do not align with the established rules and procedures for signaling the end of a jam.
