Nevada Jury Instructions
RIGHT TO ASSUME OTHERS WILL EXERCISE DUE CARE
A person who, himself, is exercising ordinary care has a right to assume that every other person will perform his duty under the law; and in the absence of reasonable cause for thinking otherwise, it is not negligence for such a person to fail to anticipate injury which can come to him only from a violation of law or duty by another.
