Which of the following best describes the penalty system in Roller Derby?

The best description of the penalty system in Roller Derby is that penalties are cumulative per game. This means that a player's penalties accumulate throughout the game, and if a player reaches a certain number of penalties, they may be disqualified from the game. In Roller Derby, this accumulation of penalties emphasizes the importance of maintaining legal play and good sportsmanship, as each infraction can lead to a harsher consequence for the player.

The other concepts surrounding the penalty system do not accurately capture the essence of how penalties function during gameplay. While some penalties may need to be served immediately, leading to a player being temporarily removed from the game, it is the accumulation over time that is critical in understanding the penalty system. Additionally, penalties are not solely based on contact; there are various infractions, including those related to illegal behavior or unsportsmanlike conduct, that can lead to a penalty. Finally, while game officials may review penalties to ensure accuracy in calls, the penalties themselves are typically enforced during the game, rather than being reviewed only post-game. This cumulative aspect places significant importance on player conduct throughout the entire duration of the match.
