HM's can be used in both battle and outside situations. In order to pass some of the stages in the game you would need HMs and possibly a badge to use it. If you trade for a Pokemon who know HMs, it is possible that you may be able to skip parts of the game, a thing which the programmers don't want due to the player shortcut-ting.
