As a general principle of law, the owner of a property is typically not liable for failing to warn invited guests of hazards that are considered “open and obvious” to any “reasonable person.” In other words, if you see a giant puddle of water in the middle of a store aisle, choose to walk over it, and slip and fall, you may have a difficult time suing the store’s owner for failing to inform you of the danger. All the owner needs to do is point out the hazard–the puddle of water–was open and obvious to any reasonable person who was paying attention to their surroundings.

But, if you will pardon the pun, it is not always obvious when a hazard is “open and obvious.” Judges and juries need to carefully weigh the available evidence in a given case. Even where the danger is ultimately found to be open and obvious, that does not always completely absolve the property owner of liability.
