Defendant appeals his conviction in a trial to the court for driving while suspended. ORS 487.560. We affirm.
ORS 487.560 provides in relevant part:
“(1) A person commits the crime of driving while suspended or revoked if the person drives a motor vehicle upon a highway during a period when the person’s license or permit to drive a motor vehicle or the person’s right to apply for a license to drive a motor vehicle in this state has been suspended or revoked by a court or by the division * * *.”
“(2) In a prosecution under subsection (1) of this section, it is an affirmative defense that:
“(a) An injury or immediate threat of injury to human or animal life and the urgency of the circumstances made it necessary for the defendant to drive a motor vehicle at the time and place in question; or
“ (b) The defendant had not received notice of the defendant’s suspension or revocation as required by ORS 482.570 or in the manner provided in paragraph (c) of subsection (3) of this section.
“(3) The affirmative defense under paragraph (b) of subsection (2) of this section shall not be available to the defendant if:
“(a) The defendant refused to sign a receipt for the certified mail containing the notice; or
“(b) The notice could not be delivered to the defendant because the defendant had not notified the division of the defendant’s address or a change in the defendant’s residence as required by ORS 482.290(3); or
“(c) At a previous court appearance, the defendant had been informed by a trial judge that the judge was ordering a suspension or revocation of the defendant’s license, permit or right to apply; or
“(d) The defendant had actual knowledge of the suspension or revocation by any means prior to the time the defendant was stopped on the current charge.
“(4) Any of the evidence specified in subsection (3) of this section may be offered in the prosecution’s case in chief.”
Before trial, defendant notified the state of his intent *506to rely on an affirmative defense under ORS 487.560(2). ORS 161.055(2) provides that when an affirmative defense is raised at trial “the defendant has the burden of proving the defense by a preponderance of the evidence.”
The state proved that defendant drove a motor vehicle on a highway during the time when his license was suspended. Defendant produced no evidence but claimed that he was entitled to be acquitted, because he had not received notice of his suspension from the Motor Vehicles Division as required by ORS 482.570:
“When the division, as authorized or required, suspends, revokes or cancels a license or the right to apply for a license to operate motor vehicles, it shall give notice of such action to the person whose license or right is affected. The notice shall state the nature and reason for the action and, in the case of a suspension, whether it was ordered by a court. Service of the notice is accomplished either hy mailing the notice by certified mail restricted delivery, return receipt requested, to the person’s address as shown by division records, or, by personal service in the same manner as a summons is served in an action by law.” (Emphasis supplied.)
Included in the state’s evidence was the envelope in which the division had mailed a copy of the suspension order by certified mail, restricted delivery, return receipt requested, to defendant at his address as shown by division records. Attached to the envelope was a piece of paper labeled “CLAIM CHECK No. 670363” containing the following notations:
“DATE
“4-28-83
“1st NOTICE
“5-3
“2nd NOTICE
“5-13
“ RETURN
“Detached from
“PS Form 3849-A
“Oct 1980”
The envelope bore the imprint of a hand pointing toward the *507return address of the division and bearing the words “return to sender.” Beneath the imprint of the hand, a handwritten “X” had been placed after the stamped word “UNCLAIMED.”
Defendant argued at trial and on appeal that the affirmative defense that he had not received notice of the suspension was established as a matter of law. He relied at trial on State v. Buttrey, 293 Or 575, 651 P2d 1075 (1982). On appeal, he relies on State v. McCollum, 48 Or App 35, 615 P2d 1194 (1980), in addition to Buttrey.
In State v. Buttrey, supra, the court stated:
“The legislative intent is clear: The state makes a prima facie case upon proof of the two elements in ORS 487.560(1), without proof of a culpable mental state, i.e., without proof of any knowledge by the defendant of the license suspension. The defendant can avoid liability by establishing the affirmative defense by a preponderance of the evidence. ORS 161.055(2). The state, in turn, can avoid the effect of the notice defense afforded by ORS 487.560(2)(b) by establishing beyond any reasonable doubt that the defendant ‘refused to sign a receipt for the certified mail containing the notice,’ ORS 487.560(3)(a), or that ‘[t]he notice could not be delivered * * * because he had not notified the division of his address or a change in his residence as required by subsection (3) of ORS 482.290,’ ORS 487.560(3)(b), or that the defendant had been informed by a trial judge that the judge was ordering a suspension of the license, ORS 487.560(3)(c), or that the defendant had actual knowledge of the suspension, ORS 487.560(3)(d).” 293 Or at 583. (Emphasis supplied.)
Defendant reads Buttrey to say more than it actually does. By his reading, his notice of intent to rely on an affirmative defense without more, shifted the burden to the state to prove beyond a reasonable doubt that the defense was not available to him for one of the reasons set out in ORS 487.560(3). As Buttrey makes clear, a defendant must establish the affirmative defense by a preponderance of the evidence. Merely giving notice of the defense does not accomplish that. Evidence depriving á defendant of the affirmative defense may be offered in the prosecution’s case in chief when a defendant has raised a defense of lack of notice, but it need not be. ORS 487.560(4).
*508In State v. McCollum, supra, this court held only that the affirmative defense of lack of notice was not made unavailable by proof that the notice was sent by certified mail, restricted delivery, return receipt requested. We did not hold that the envelopes containing the notices with the notations that they were unclaimed established the defense of lack of notice as a matter of law, which is what defendant asks us to do here.
Defendant’s sole claim is that the postal service stamp, directing that the envelope containing the notice that his driver’s license was suspended and indicating that the envelope was unclaimed, establishes as a matter of law that he did not receive the notice.1 He does not claim that the notice was not mailed to his address as shown by division records or, for that matter, that the address was not his place of residence.2 That the envelope was marked “unclaimed” is the only evidence on the issue of receipt of the notice, because defendant offered no evidence.3
There is, however, evidence of notice contained on the envelope in the form of the claim check attached to it. It *509allows the inference that, in accordance with Section 912.55 of the Postal Services Domestic Mail Manual,4 notices that mail was being held for defendant at the post office were left at his address. That defendant failed to pick up his mail, after receiving notice that it was at the post office, creates a fact question as to whether the mail was delivered, and the trial court was not bound to find that the notice was not received as a matter of law. That question of fact could be resolved against defendant. The judge, sitting as the trier of fact, did so. Neither State v. Buttrey, supra, nor State v. McCollum, supra, dictates a contrary result.5
Affirmed.
The dissent would make something of the fact that we do not know from the evidence whether defendant knew that the letter being held for him at the post office was from MVD. That fact, even if it were affirmatively established that he did not know, is of no significance. The issue is whether the trial judge, as finder of fact, could find that defendant received the letter, not whether defendant received a letter that he knew came from MVD.
The dissent appears to concede that the evidence “permits an inference that [defendant] received postal notices that a certified letter was being held for him at the post office.” That permissible inference and defendant’s failure to respond to the postal notices is enough to allow a trier of fact to find that he received the letter. This situation is not materially different than it would be if the letter had been delivered to his post office box, and he had merely failed to retrieve it. It had gone as far as the postal service was going to take it without his claiming it. The trier of fact could find that, without more, it had been received.
The dissent miscasts the majority position and defendant’s claim. (1) We have not suggested that defendant is claiming that envelopes marked “Unclaimed” establish as a matter of law that defendants in other cases have not received notices of suspension. (2) Defendant’s claim is not simply that the evidence establishes by a preponderance of the evidence that he did not receive the suspension notice. (If it was, it would fail; we do not review de novo.) His claim is that the evidence establishes that he did not receive the notice as a matter of law. Defendant’s first assignment of error says so in so many words. (3) We do not suggest that defendant was obligated to testify in his own behalf to establish his defense but only point out, as is clear from the statute, that the defense of lack of notice is an affirmative defense and that the burden of proving an affirmative defense is on the one asserting it.
That section is cited by both defendant and the state in their briefs on appeal.
Defendant also argued to the trial court that our holding in State v. Monaco, 55 Or App 122, 637 P2d 221 (1981), required his acquittal. His brief on appeal does not cite State v. Monaco, supra, and we assume, therefore, that he has abandoned that argument.
