Res ipsa loquitur ("the thing speaks for itself") is a tort law doctrine allowing plaintiffs to infer a defendant's negligence from the nature of an accident when there's no direct evidence, meaning the event itself suggests fault. To apply it, three conditions must usually be met: the accident wouldn't normally happen without negligence, the instrument causing harm was under the defendant's exclusive control, and the plaintiff didn't contribute. It helps plaintiffs in cases like medical malpractice where proving exact negligence is difficult.

Res ipsa loquitur examples (the "thing speaks for itself") involve accidents that ordinarily don't happen without negligence, like surgical instruments left in patients, pianos falling from windows, exploding soda bottles, or sudden elevator drops, allowing courts to infer the defendant's carelessness without direct proof, as seen in cases of wrong-site surgery or falling construction debris. These situations suggest someone was negligent because they wouldn't occur otherwise, shifting the burden to the defendant to disprove fault.

The three main types of torts are Intentional Torts, where a person purposefully causes harm (like assault); Negligent Torts, where carelessness leads to injury (like a car accident); and Strict Liability Torts, where liability is imposed regardless of fault, often for dangerous activities or defective products. These categories determine the elements a plaintiff must prove, with negligence being the most common type involving unreasonable actions, while strict liability holds defendants responsible even without intent or carelessness.
