FRE 407: Subsequent Remedial Measures
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:
- 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.
