In the law of NEGLIGENCE, the reasonable person standard is the standard of care that a reasonably prudent person would observe under a given set of circumstances. An individual who subscribes to such standards can avoid liability for negligence. Similarly a reasonable act is that which might fairly and properly be required of an individual.
