The issue of the credibility of plaintiff’s damages was not or should not have been before the trial judge on a motion for directed verdict. The jury and not the judge passes on credibility. The question is whether the plaintiff has offered enough evidence to permit a legitimate inference of negligence on the part of the defendant. We hold that the evidence as to defendant’s backing up and the damage to plaintiff and her car presented a legitimate inference of negligence in the form of improper lookout or excessive speed, or both. See Conway v. Timbers, Inc., 7 N.C. App. 10, 171 S.E. 2d 62 (1969), cert. denied, 276 N.C. 183 (1970); Murray v. Wyatt, 245 N.C. 123, 95 S.E. 2d 541 (1956).
