When measures are taken that would have made an earlier injury or harm less likely to occur, evidence of the subsequent measures is not admissible to prove negligence, culpable conduct, a defect in a product or its design or a need for a warning or instruction. However, a court may admit such evidence for another purpose, such as impeachment or, if disputed, proving ownership, control, or feasibility of precautionary measures.
