Within the official rulebooks governing American football, a direct twenty-yard penalty does not exist as a standard, standalone yardage assessment for typical infractions. Minor and moderate rule violations generally result in five, ten, or fifteen-yard penalties, such as holding, false starts, face mask infractions, or unsportsmanlike conduct fouls. However, compounding multiple penalties on a single play, enforcing specific pass interference spot fouls, or applying safety-related enforcements can occasionally result in cumulative yardage advancements or back-ups that equal or exceed twenty yards, but the referee signal code itself features no specific twenty-yard infraction category.
