Idaho Rules of Evidence Rule 407. Subsequent Remedial Measures.
When, after an injury or harm allegedly caused by an event, measures are taken which, if taken previously, would have made the event less likely to occur, evidence of the subsequent measures is not admissible to prove negligence or culpable conduct, or a defect in a product, a defect in a product's design, or a need for a warning or instruction. This rule does not require the exclusion of evidence of subsequent measures if offered for another purpose, such as proving ownership, control, or feasibility of precautionary measures, if controverted, or impeachment.
