Foreseeable Risk

A likelihood of injury or damage that a reasonable person should be able to anticipate in a given set of circumstances. Foreseeable risk is a common affirmative defense put up by defendants in lawsuits for negligence, essentially claiming that the plaintiff should have thought twice before taking a risky action. Signs that warn "use at your own risk" do not bar lawsuits over injuries or damages from risks that weren't foreseeable.
