(a) Opinion and reputation evidence of character. The credibility of a witness may be impeached or supported by evidence of character for truthfulness or untruthfulness in the form of opinion or reputation. Evidence of truthful character is admissible only after the character of the witness for truthfulness has been impeached.
(b) Specific instances of conduct.
(1) General rule. A witness may be asked, in good faith, about specific instances of conduct of the witness, if probative of the witness' character for untruthfulness.
(2) Extrinsic evidence. Specific instances of the conduct of a witness, for the purpose of impeaching the witness' credibility under subdivision (1), may not be proved by extrinsic evidence.
(c) Inquiry of character witness. A witness who has testified about the character of another witness for truthfulness or untruthfulness may be asked on cross-examination, in good faith, about specific instances of conduct of the other witness if probative of the other witness' character for truthfulness or untruthfulness.
