Negligence law explores when people can be held responsible for harming others through carelessness. It requires proving duty, breach, causation, and damages. Special duties arise in certain relationships, like common carriers and professionals, while exceptions limit liability in some situations. Causation and damages can get tricky, with multiple causes and complex calculations for future losses. Defenses like comparative negligence and assumption of risk can reduce or eliminate liability. Real-world examples span slip-and-falls to medical malpractice, showing negligence's broad application.
