A danger which a reasonable person should anticipate as the result from his/her actions. foreseeable risk is a common affirmative defense put up as a response by defendants in lawsuits for negligence. a skier hits a bump on a ski run, falls and breaks his leg. this is a foreseeable risk of skiing. a mother is severely injured while accompanying her child on a roller coaster when the car jumps the track and comes loose. while there is potential risk, she had the right to anticipate that the roller coaster was properly maintained and did not assume the risk that it would come apart. signs that warn “use at your own risk” do not bar lawsuits for risks that are not foreseeable.
