Okla. Stat. tit. 12, § 12-2407: 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 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.
