Fed. R. Evid. 407 — Subsequent Remedial Measures
Plain English
After an accident, fixing the hazard cannot be used against you to prove negligence, culpable conduct, a product or design defect, or that a warning was needed. The policy is simple: we want people to make repairs without fearing the fix becomes an admission. But the evidence can come in for other purposes—impeachment, or, if disputed, ownership, control, or the feasibility of precautions.
From the Courtroom
This rule protects the post-accident fix, but the exceptions are where cases turn. If the defense argues “there was no safer way to do it,” feasibility is in dispute and the subsequent fix comes in. Same if they deny owning or controlling the premises. Never offer the repair to prove negligence; offer it to rebut a feasibility or control defense, or to impeach a witness who overclaims.
Key Points & Authority
- Barred uses. Subsequent remedial measures are inadmissible to prove negligence, culpable conduct, a product or design defect, or a need for a warning/instruction.
- Permitted purposes. Impeachment; or, if disputed, ownership, control, or feasibility of precautionary measures.
- Policy. Encourage safety improvements without penalizing the repair.
Florida Parallel
Florida Parallel: Fed. R. Evid. 407 corresponds to § 90.407, Fla. Stat. (Subsequent remedial measures). Both bar use of later repairs to prove negligence or culpable conduct; the precise scope of the exceptions has its own Florida gloss, so compare.

Rule Text (verbatim from the Florida Supreme Court)
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.
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.
