If you fall on a slippery floor in a store, can you sue for negligence?

Yes, you can sue for negligence in a type of case that is known as a slip and fall. Generally, a plaintiff must show either that there was a foreign substance on the floor that caused the plaintiff harm or that the substance on the floor was on the floor long enough so that store employees knew or should have known of its existence. This explains why in many stores there will be a sign warning of slick spots to prevent people from falling and hurting themselves and also to prevent slip and fall lawsuits. The doctrine of res ipsa loquitur does not apply in slip and fall cases.
