Appellant was found guilty of one count of unauthorized use of a motor vehicle (UUV) (D.C.Code § 22-3815 (1989)). 1 He contends that the trial judge erred in refusing to modify the standard jury instruction setting forth the elements of that offense 2 to incorporate his defensе that he believed, though mistakenly, that someone other than the true owner had authority to consent to his use of the vehicle. We agree with appellant and hold that, upon request, where the accused defends against a charge of UUV by asserting the belief that a third party was empowered to allow him to use the vehicle, the trial judge should instruct the jury essentially in the manner requested by appellant. Because the modified instruction was requested and not givеn here, and because its omission was not harmless on the particular facts of this case, we reverse and remand for a new trial.
I.
The government’s evidence showed that appellant was stopped by the police whilе driving a Dodge Colt automobile about 1:30 a.m. without the owner’s consent to do so. The car did not have a key in the ignition switch, and the ignition had been punched out. The defense testimony was that a fifteen-year-old friend drove up to aрpellant on the street, asked appellant to drive him to his girlfriend’s house, and moved to the passenger seat so that appellant could drive. Appellant knew that the car did not belong to his friend and also knew that the friend wаs too young to drive lawfully. He testified, however, that he thought the *92 friend had permission to use the car (and hence to allow him to drive) because he had seen him driving cars before, including the same one earlier that evening, and was unaware of any problem concerning the cars the friend had driven. 3 The issue before us is not the plausibility of this defense but the trial judge’s refusal to give a requested instruction allowing the jury to focus specifically on the friend’s role in deciding whеther appellant knew he lacked the owner’s consent.
In his request for instructions, appellant asked the judge to supplement the standard jury charge for unauthorized use of a vehicle by adding the language, “or some other person empowered to consent in the owner’s behalf,” to the third and fourth elements of the standard instruction. 4 The judge denied appellant’s request and, over his objection, gave the standard instruction without the added language. During its delibеrations, the jury sent out two notes, the first asking for reinstruction on the elements of the two offenses. The second asked, specifically with regard to the unauthorized use count, “Should the authorization that we are discussing be from the owner or the fifteen-year-old?” The judge responded by repeating the standard instruction, again over appellant’s objection and request for the supplemented instruction. The jury returned a verdict of guilty on the latter count.

In
Powell v. United States,
The government correctly asserts that there was no еvidence that the owner in fact had authorized the juvenile to use the car, much less to allow another to drive it. Thus, had appellant asked the trial judge to modify only the third element of the standard instruction, see note 4,
supra,
by adding the “some other person” lan
*93
guage, the сourt would have been correct in denying the modification. But as the standard instruction and our decisions make clear, there is a fourth element of the offense which requires the government to prove that at the time the defendаnt used the vehicle, he
knew
he did so without the consent of the owner.
See Allen v. United States,
“A defendant in a criminal case is entitled to a jury instruction on any issue fairly raised by the evidence, ‘however weak’ that evidence may be.”
Carter v. United States,
The remaining question is whether the failure to supplement the standard instruction as requested affected appellant’s substаntial rights. D.C.Code § ll-721(e) (1989). Ordinarily we would find it difficult to conclude that failure to add the “some other person” language was so prejudicial as to require reversal of a conviction. That is because the unmodified standard instruction does nоt prevent an accused from arguing, as appellant did here, that if the jury believed he genuinely thought his friend had authority to use the car and let him drive it temporarily, he lacked the knowledge required by the statute. The problem in this casе is that the jury labored under apparent uncertainty on the very point of whether the third party’s consent (rather than the owner’s) was relevant to appellant’s knowledge. Its second note to the court asked, “Should the authorization that we are discussing be from the owner or the fifteen-year-old?” A logical inference is that the jury was concerned, in substantial part, with whether it
mattered
that appellant testified he believed his friend had consent to use the car if therе was no evidence the owner in fact had given permission. The instruction appellant sought, and the court refused, went directly to this point. True, even with the requested instruction the jury might have found that appellant knew his underage and unlicensed friend lacked permission to use the car. But we know the jury was troubled by the relevance of the authority on which appellant purported to rely, and we cannot hold with assurance that the evidence supporting his clаimed lack of knowledge was so weak that the omitted instruction would have had no effect on the jury’s decision.
Kotteakos v. United States,
Accordingly, the judgment of the Superi- or Court is
Reversed.
Notes
. Appellant was also charged with one count of receiving stolen property (D.C.Code- §§ 22-3832(a), (c)(1) (1989)), but the jury found him not guilty of thаt charge.
. Criminal Jury Instructions for the District of Columbia, No. 4.66 (3d ed. 1978).
. Appellant claimed that the car was an automatic and the engine was running when he got into the car, hence he had no occasion to use the ignition switch until the police stopped him and told him to turn off the ignition. He insisted he had seen his young friend "sometimes ... do errands for people and they let him use their car for about two or three hours."
. The standard instruction, as supplemented by the language (herе italicized) which appellant requested, would require the government to prove:
1. That a person took a motor vehicle or that he used, operated, or removed it from any place, or that he caused it to bе taken, used, operated, or removed from any place;
2. That he operated it, drove it, or caused it to be operated or driven for his own profit, use or purpose;
3. That he did so without the consent of the owner or some other person empowerеd to consent in the owner’s behalf; and
4.That at the time the defendant took, used, operated, or removed the vehicle or caused it to be taken, used, operated or removed he knew that he did so without the consent of the owner or some other person empowered to consent in the owner’s behalf.
. The government relies on the following brief statement by the
Powell
court in a footnote: ‘The situation revealed by the evidence in this case doеs not require the expression of an opinion as to the efficacy of an
apparently
valid permission granted by one who was not authorized by the vehicle’s owner to consent to its use.”
. The government does not dispute that the fourth, or knowledge, element is firmly embedded in the requirements for conviction of unauthorized use of a motor vehicle.
