Sometimes these are to circumvent flaws in the game engine that would otherwise cause you to get stuck some crevices, more often as artificial boundary for the area where you're "allowed" to play. For the latter it's usually sign of poor level design or unnecessarily restricting gameplay.

Also cases where some minor rubble that you'd except the character to be able to walk over without effort, especially if in other cases you can do just that.

These are also often present at the borders of watery bodies of various sizes but should be ignored in their case if there's no perceivable reason to actually allow swimming.

Sometimes present at edges of high ledges that would certainly (by common sense) kill the player character if she fell off, these can be considered as representation of the character's common sense (outside of the player's judgement) to not jump off and should not be considered, though they can be included if mentioned. Any similar cases included.
