Just like in soccer, a red card represents the highest level of penalty, reserved for severe misconduct or foul play.
Interestingly, gymnastics has its own version of the red card system.
Yellow and red cards in gymnastics are issued for unsportsmanlike conduct. A first offense earns a yellow card as a warning, while a second offense leads to a red card and immediate removal from the competition. This system encourages fair play and ensures everyone understands the consequences of misconduct. In cases of flagrant, undisciplined, or abusive behavior toward a judge, a red card can be issued immediately, regardless of prior warnings.
What makes this policy unique is that yellow and red cards are only given to coaches, not gymnasts. Coaches are subject to these penalties, while gymnasts receive different consequences for similar actions.

According to current rules, gymnasts may receive a 0.30-point deduction from their final score for "undisciplined or abusive behavior," as determined by the D1 judge. Notably, this penalty impacts only their score and does not involve the issuance of a yellow card.
This means that, in practice, a gymnast could engage in highly inappropriate actions, such as throwing mats across the gym or using profanities, and the sole specified consequence would be a 0.30-point deduction.
