Reasonable Person

Reasonable Person

A phrase used to define a hypothetical person who exercises qualities of attention, knowledge, intelligence, and judgment that society requires of its members for the protection of his or her own interest and the interests of others. Thus, the test of negligence is based on either a failure to do something that a reasonable person, guided by considerations that ordinarily regulate conduct, would do, or on the doing of something that a reasonable and prudent (wise) person would not do.
