What action should be avoided to prevent 'blocking out-of-bounds'?

The action that should be avoided to prevent 'blocking out-of-bounds' is hitting opponents towards the outer edge. In roller derby, when a blocker makes contact with an opponent and directs them towards the outer boundary of the track, it can result in the opponent being pushed out of bounds. This is not only against the rules but also endangers the integrity of the play and can lead to penalties for the blocker.

Staying within the designated track boundaries is essential for all players during the game. When a player goes out of bounds, they lose their ability to legally engage with opponents until they re-enter the track in a safe manner. Making contact with an opponent's skates can also be a risky move, as it can lead to loss of balance and control, but it does not directly correlate to the concept of blocking. Using shoulder checks against blockers is a strategic defensive move that can be executed properly without leading to out-of-bounds incidents if done within the rules.

Overall, ensuring that players are not incorrectly pushed out of bounds during block attempts helps maintain the flow of the game and keeps competitors safe on the track.
