Negligence is the failure to exercise reasonable care, resulting in harm to another person or property. It involves a person's conduct falling below the standard of care expected of a reasonable person in similar circumstances. Negligence can be either intentional or accidental. There are three main types of negligence: contributory negligence, comparative negligence, and strict liability. Contributory negligence is when a victim's own negligence contributed to their injury or loss. Comparative negligence is when the victim and the defendant are both found to be partially at fault. Strict liability is when the defendant is held liable for the harm, regardless of their actual intent or negligence.
