By his assignment of error number 4, defendant contends the trial judge expressed an opinion to the jury in violation of G.S. 1-180 by extensively questioning defendant and his witnesses. The assignment is sustained.
The record reveals that in the initial presentation of its case, the State introduced three witnesses. On the initial presentation, the trial judge did not ask two of the witnesses any questions and asked the third witness two questions. Defendant then presented nine witnesses in addition to himself, the first of his witnesses being Columbus (Lump) Williams. After the examination, cross-examination and redirect examination of Williams, the following occurred :
“The Court: Was she open?
Answer by Witness : No, sir.
The Court : What did you stop by there for if the store was closed?
Answer by Witness: I seen a whole lot of cars up there so I went by there.
The Court : What business did you have there ?
Answer by Witness: I didn’t have no business up there.
THE' COURT: When did you stop drinking?
*130Answer by Witness : That has been in 1971.
The Court : When were you convicted of driving under the influence?
Answer by Witness : April.
The Court: What year?
Answer by Witness : 1971.”
Columbus Williams was followed on the witness stand by William Heckstall and his cross-examination was interrupted by the trial judge as follows:
“The Court: Mr. Heckstall, have you heard William Smallwood make a statement more than one time about whether or not he was at the scene of the death ?
Answer by Witness : I have not heard it but one time and that was when he came to my house.
The Court: You have not heard him say anything about it since then?
Answer by Witness Heckstall: No, not since that Sunday morning.
The Court: After the death?
Answer by Witness: Yes, after the death.”
While defendant was on the witness stand and following his direct examination, cross-examination, redirect examination and further cross-examination, the record discloses the following:

Following the examination and cross-examination of defense witness Stanley Haywood Bond, the record sets forth the following:

A. Yes, sir.
The Court: All right.”
After defendant rested his case, the State offered several witnesses in rebuttal. Among those was Marie Smallwood and *134at the conclusion of her testimony the record discloses the following :
“Court: ‘All of these men were out there without their wives as far as you know, weren’t they?’ Answer by witness: T don’t know, I was not there.’ ”
It is well settled that in the trial of criminal actions, the court may ask a witness questions designed to obtain a proper understanding and clarification of the witness’ testimony or to bring out some fact overlooked, but the court may not ask a defendant or a witness questions tending to impeach him or to cast doubt upon his credibility. State v. McEachern, 283 N.C. 57, 194 S.E. 2d 787 (1973); State v. Frazier, 278 N.C. 458, 180 S.E. 2d 128 (1971); State v. Kirby, 273 N.C. 306, 160 S.E. 2d 24 (1968); State v. Lowery, 12 N.C. App. 538, 183 S.E. 2d 797 (1971); State v. Pinkham, 18 N.C. App. 130, 196 S.E. 2d 290 (1973). The judge must exercise great care to see that nothing he does or says during the trial can be understood by the jury as an expression of an opinion on the facts or conveys an impression of judicial leaning. State v. Lynn, 246 N.C. 80, 97 S.E. 2d 451 (1957); State v. Battle, 18 N.C. App. 256, 196 S.E. 2d 536 (1973). See also State v. Sharp, 18 N.C. App. 136, 196 S.E. 2d 371 (1973) and State v. Hewitt, 19 N.C. App. 666, 199 S.E. 2d 695 (1973).
We hold that in the case at bar, the court’s questions tended to impeach defendant and his witnesses or to cast doubt on their credibility, entitling defendant to a new trial. We find it unnecessary to discuss the other assignments of error argued in defendant’s brief.
New trial.
Judges Campbell and Morris concur.
