This is an open-intersection automobile negligence case. On November 21,1967, at about 12:50 in the afternoon, an automobile collision occurred at the intersection of Sunset and Northlawn in Bast Lansing, Michigan. The plaintiff and his passenger were travelling east on North-lawn in a 1966 Volkswagen; defendant Daniel Miller, driving a 1968 Oldsmobile Cutlass owned by his father, defendant James P. Miller, was travelling north on Sunset, accompanied by a friend. The intersection of Northlawn and Sunset is not controlled by any traffic sign or signal; the speed limit for both streets was 25 miles per hour. At trial, neither plaintiff nor his passenger were able to recall any of the events of the accident. At the conclusion of the trial the jury returned a verdict in favor of plaintiff in the amount of $17,500 plus $1,190 to plaintiff’s insurance company as subrogee. Defendants moved for a new trial; the trial court, finding the jury’s verdict excessive, ordered that plaintiff file a remittitur of $5,000 or else the motion for a new trial would be granted. The remittitur was filed and defendants’ motion for a new trial was denied. Defendants appeal as of right, raising numerous allegations of error.
Defendants first contend that the trial court erred in granting plaintiff’s motion for an order preventing cross-examination of plaintiff regarding his prior traffic convictions. It appears that the admission of evidence of prior traffic convictions is proper when limited solely to testing credibility. See GCR 1963, 607;
Taylor
v
Walter,
In Sting v Davis, supra, 613-614, the Supreme Court stated:
“GCR 1963, 607 was adopted by this Court in accordance with its rulemaking powers as to evidentiary matters. The central issue in practically every contested motor vehicle accident case is whether defendant-driver was guilty of negligence and, if the plaintiff was the driver of the other motor vehicle, whether he was free from, contributory negligence. As to the defendant, the question which confronts the jury is whether to believe the claim of the plaintiff that the defendant was negligent or the claim of the defendant that he was not negligent and, as to a plaintiff-driver, the issue is just the reverse. Almost invariably, as in this case, the defendant asserts, ‘I did not drive in a negligent fashion.’ If the plaintiff was also a motor vehicle driver, as in this case, he makes the same assertion as to his driving upon finding himself accused of being the responsible party because of negligent driving. On the issue of whom to believe, the driving record of a plaintiff or of a defendant can become a crucial evidentiary factor. That driving history, both before and after the accident, whether it be for serious or minor infractions of the vehicle code, can have a vital bearing in enabling a jury to determine the truth of a plaintiff’s or a defendant’s testimony as to the exerbise of due care.
“We conclude that under GCR 1963, 607, as presently adopted by this Court, a trial judge has no discretion to exclude cross-examination with regard to the driving history of a plaintiff-driver or of a defendant-driver, such cross-examination being proper to test the credibility of the witness’ testimony with regard to the central fact issue in the case.” (Emphasis added.)
*653 In the instant case, plaintiff’s credibility regarding his exercise of due care was not at issue because, when plaintiff took the stand, he testified that he could not remember any of the circumstances of the accident, due to amnesia which resulted from the accident. Consequently, defendant had no right to impeach plaintiff’s credibility with regard to his exercise of due care as a result of plaintiff’s lack of testimony as to the circumstances surrounding the accident. Sting v Davis, supra, 613-614. Similarly, plaintiff’s driving record is not relevant with respect to the impeachment of plaintiff’s testimony that he had amnesia. Furthermore, plaintiff’s driving record is not admissible, independently, to establish whether or not plaintiff exercised due care.
Where plaintiff has not testified as to his exercise of due care, but has specifically denied remembering any of the circumstances of the accident in question, his past driving record may not be used to impeach his credibility for the simple reason that plaintiff has not made his exercise of due. care an issue by his testimony and, therefore, there is no issue of credibility which his driving record could impeach.
In the instant case, the trial court was of the opinion that the introduction by defendant of plaintiffs driving record would serve no purpose other than irreparably to prejudice plaintiff’s case. There is no issue of credibility which plaintiff’s driving record could impeach and this Court finds that the trial court’s ruling was not erroneous.
Defendants next contend that the trial court erred in allowing, over objection, plaintiff’s witness Marley Hart to express his opinion of the speed of defendant’s vehicle just prior to the collision. In

v
Bacon,
*654
_ “One need not qualify as an expert in order to testify as to matters one learns through ordinary observation such as the rate of speed at which a vehicle is going, provided a witness is. fully interrogated as to the knowledge upon which his judgment is based, so that a jury can determine what weight should be given to his statements.

Jackson
v.
Trogan
(1961),
The record shows that the jury was made aware of the witness’s opportunity to observe the accident between plaintiff and defendant, and the sole question here is what weight the jury was to give to this testimony. This is within the exclusive province of the jury and consequently the trial judge did not err in allowing the witness to testify as to his opinion as to the speed of defendant’s vehicle.
Defendants next allege that the trial court erred in admitting into evidence, as a part of plaintiff’s hospital record, the consultation report of Dr. Jakubiak. In
Shinabarger
v
Phillips,
“Appellant contends it was error to admit hospital records, made and kept in the regular course of business, concerning plaintiff’s treatment and the diagnosis which showed that he had suffered a concussion. CL 1948, § 617.53 (Stat Ann 1962 Rev § 27-.902), in effect when this case was tried made the records admissible in evidence. See
Harrison
v.
Lorenz
[1942],
In the instant case there was medical testimony by one of the plaintiff’s witnesses, Dr. Trager, which supported the objected-to diagnostic evidence. Dr. Trager stated that “he [plaintiff] could not remember what happened.” There is also other evidence in the admitted hospital records which indicates plaintiff’s inability to remember things. It, therefore, appears that, in full compliance with the holding of Shinabarger, supra, the objected-to diagnostic report of Dr. Jakubiak was otherwise substantiated on the record and, as such, was properly admitted into evidence. There was no reversible error by the trial court.
Defendants further contend that the trial court erred in denying defendants’ motion to strike the testimony of plaintiff’s rebuttal witness, Lucille Dunabeck. The admission of rebuttal testimony is purely within the discretion of the trial court. See
Gilchrist
v
Mystic Workers of the World,
The defendants also allege that the trial court erred in its instructions to the jury. Beading the trial court’s instructions as a whole, which we must do, we find the instructions were not erroneous.
Finally, defendants contend that the trial court erred in refusing to direct a verdict in defendants’ favor and in denying defendants’ motion for a new
*657
trial. In the instant case there were many disputed factual questions and, consequently, the case was properly submitted to the jury. Furthermore, there does not appear to be any abuse of discretion on the part of the trial court either in refusing defendants’ motion for directed verdict or in denying defendants’ motion for new trial. As there was no abuse of discretion on the part of the trial court, the trial court is affirmed.
