Rule 11-407. Subsequent remedial measures.

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