This is a truck-motorcycle accident case. Tim Brown, a minor, through his father and next friend, Terry Brown, instituted suit against Tom Smith for personal injuries. The father likewise sued for medical expenses. The case was tried to a jury, and that body returned a verdict in favor of the defendant. The verdict was approved by the Trial Judge who overruled plaintiffs’ motion for a new trial; and plaintiffs have timely perfected their appeal to this Court.
On June 18,1977, Tim Brown, age twelve, was riding as a guest passenger on a motorcycle driven by his step-uncle, Richard Brown, age fifteen, on Kaye Road in rural Gibson County. The motorcycle met and attempted to pass in a ninety degree turn a GMC pickup truck being driven in the opposite direction by Tom Smith. The road was relatively narrow and surfaced with loose gravel. The truck and motorcycle collided, and Tim Brown was injured. Plaintiffs insist that the defendant was negligent in that he failed to pull his truck to the right hand side of the road in order to yield a portion of the road to the motorcycle. The defendant denied negligence on his part and alleged that the cause of the accident was the negligence of Richard Brown in operating the motorcycle and the contributory negligence of Tim Brown. Defendant also pled assumption of risk and the violation of certain statutes.
In our disposition of this case it is not necessary to detail the evidence offered at trial. It is enough to say that the determinative issues were the negligence, if any, of the defendant and the contributory negligence, if any, of the plaintiffs or either of them. On appeal plaintiffs present for our review the following insistence:
The Court erred in its supplemental charge to the Jury in regard to the standard of care and caution required of a minor guest passenger on/in a motor vehicle, in that the charge was erroneous according to law, and that it affirmatively affected the results of the trial.
In his charge in chief the Trial Judge instructed the jury, in part, with respect to the alleged contributory negligence of Tim Brown as follows:
The plaintiff, Tim Brown, has been accused of contributory negligence in this action and you must determine whether this accusation is true. A matter (sic:minor) will not be held to the standard of care imposed on adults, rather he is charged with such care as a reasonably prudent person of like age, capacity, knowledge and experience would be expected ordinarily to exercise. The law presumes that one between the ages of 7 and 14 is incapable of negligent conduct but you may determine that the evidence has counterbalanced that presumption and find that the minor plaintiff is guilty of contributory negligence, (emphasis added)
After the jury retired to deliberate, Mr. Kizer, attorney for the defendant, made certain objections to the Court’s charge; and the record reflects the following exchange.
“MR. KIZER: .... Secondly, we also want to object to Your Honor’s instruction with reference to negligence of a minor because it was held in Power v. Hartford Life, an accident (sic:and Accident) in 398 Tennessee, a case in Judge Taylor’s court, that one operating a motor vehicle has the same degree of care as an adult. I think that would apply to one who was riding on it.
THE COURT: I’m inclined to agree with that.
MR. KIZER: We want to object to that part of Your Honor’s charge.
THE COURT: Let that jury come back in.
(WHEREUPON, the jury returned to open court for further instructions from the Court.)
THE COURT: The point he is making, Mr. Harrell, is that other courts have held *58that the operator of a motor vehicle in Tennessee, regardless of age, is held to the same standards of care as an adult.
MR. HARRELL: The operator but I’m talking about a guest passenger.
THE COURT: I think it would be true if he’s a voluntary passenger.
MR. HARRELL: Please note our exception.
THE COURT: Yes, sir. Very briefly, ladies and gentlemen, two points that I wish to cover. First is that the mere riding of a passenger on a motorbike, that standing alone, is not to be considered an assumption of any risk inherent in doing it. And, secondly, that, in Tennessee, the operator, a minor, that is, a person under the age of 18, who operates a motor vehicle is held to the same standard of conduct, the same standard of care and caution as an adult. And that would be true likewise of a passenger of a motor vehicle who voluntarily assumes to ride it. So, in this case, all these parties are held to the same standard of care and caution. I thought that, perhaps, as a result of the charge I gave you with respect to the duties of a minor, that there might be some misunderstanding in your mind about it. All of them had the same duty of care, regardless of age.” (emphasis added)
After further deliberation the jury returned to open Court where the following occurred:
“FOREMAN: We find neglect on both sides. If that answer is not acceptable, we’ll have to retire for further deliberation.
THE COURT: All right, ladies and gentlemen, the foreman reports that you find that each party was negligent and do you dismiss the plaintiff’s action for that reason?
(Jury members respond affirmatively.) THE COURT: So say you all? Please raise your right hand if that’s the verdict of each one of you. Court dismissed.”
We find that the Trial Judge in his charge in chief properly instructed the jury as to the standard of care imposed upon Tim Brown, a minor twelve years of age; and that the instruction given in the supplemental charge was clearly erroneous. It is apparent that the supplemental charge amounted to an extension of the holding of the Supreme Court in the case of Powell v. Hartford Accident Indemnity Co., 217 Tenn. 503, 398 S.W.2d 727 (1966) which involved the minor operator of a motor scooter. In Powell the Supreme Court first held that a minor operating a motor vehicle on the public highways of this state is charged with the same standard of care as an adult person. The Supreme Court, however, has expressly declined to extend that standard to a minor guest passenger. See Duvall Transfer and Delivery Service v. Beaman, 218 Tenn. 348, 403 S.W.2d 315 (1966) and Houser v. Persinger, 57 Tenn.App. 401, 419 S.W.2d 179 (cert. den. 1967). Tim Brown as a guest passenger was charged with that degree of care ordinarily exercised by a person of like age, discretion, knowledge and experience as stated in the charge in chief.
On this record we are of the opinion that the minor plaintiff was materially prejudiced by the erroneous supplemental charge to the jury; and since the alleged contributory negligence of the minor plaintiff was a principal issue in the case, it does affirmatively appear that such error affected the results of the trial. T.C.A. 27-117. Therefore, it is the obligation of this Court to reverse and remand for consideration by a jury under proper instructions.
Accordingly, the judgment in favor of defendant is reversed, and the case is remanded for a new trial. Costs of appeal are adjudged against the defendant, Tom Smith.
