1. (1) The judge shall exercise reasonable control over the mode and order of the interrogation of witnesses and the presentation of evidence, so as to:

   1. (a) Facilitate, through effective interrogation and presentation, the discovery of the truth.
   2. (b) Avoid needless consumption of time.
   3. (c) Protect witnesses from harassment or undue embarrassment.
2. (2) Cross-examination of a witness is limited to the subject matter of the direct examination and matters affecting the credibility of the witness. The court may, in its discretion, permit inquiry into additional matters.
3. (3) Leading questions should not be used on the direct examination of a witness except as may be necessary to develop the witness's testimony. Ordinarily, leading questions should be permitted on cross-examination. When a party calls a hostile witness, an adverse party, or a witness identified with an adverse party, interrogation may be by leading questions.
