Yellow card: warning (impeding, holding, kicking deliberately, illegal feed); Red card: disqualification; Two yellows: automatic disqualification
Why people argue about this
People often assume that getting two yellow cards for impeding in a row means you're automatically disqualified right away, but actually, it triggers an automatic disqualification only if these incidents happen consecutively during the same race leg or segment of swimming. They miss understanding the rule's conditionality and context within the overall race structure.
