DeHOOG, P. J.

Plaintiff brought this premises-liability action against defendant, Port of Portland, seeking damages for injuries he sustained when he tripped over his own luggage and cut his foot on the bottom edge of a baggage carousel at the Portland International Airport (PDX). Plaintiff now appeals a general judgment of dismissal entered following a jury verdict in defendant's favor. The jury found that, although the fault of each party had been a cause of plaintiff's injury, plaintiff was more at fault than defendant; plaintiff, therefore, was not entitled to recover, and the trial court dismissed his claim. As we discuss below, plaintiff presents his appeal as raising a novel question of law: whether, in a premises-liability case, a business invitee's negligent conduct can give rise to comparative fault when the invitee did not know and could not have known of the presence of the dangerous condition or unreasonable risk of harm that allegedly caused the invitee's injury. Plaintiff argues that his status as a business invitee on defendant's premises limited his duty of care to acting reasonably to avoid harm from conditions of which he was, or at least should have been, aware, which, he contends, did not include the sharp underside of the baggage carousel. Defendant responds that a plaintiff's reasonable care for his own safety is always relevant to comparative fault, even in a premises-liability case. For the reasons that follow, we conclude that the trial court did not err in dismissing plaintiff's claim. Accordingly, we affirm.

At the outset, we clarify our understanding that, although plaintiff raises two assignments of error on appeal, his assignments share a single premise, and our assessment of that premise will determine that outcome of this appeal. Plaintiff argues under his first assignment of error that his negligence in tripping over his own luggage could play no role in the jury's attribution of fault for his injury. In his second assignment of error, plaintiff argues that there was no evidence to support defendant's assertion that he was negligent with regard to the injury that he suffered. Ultimately, both assignments of error rest on the same premise, which is that, because plaintiff neither knew nor had any reason to know that the base of defendant's baggage carousel had a dangerously sharp edge, no fault can be attributed to him for the injury that he suffered as a result of that condition. With that understanding in mind, we proceed.

I. FACTS AND PROCEDURAL BACKGROUND

Plaintiff's numerous assignments of error implicate various standards of review, not all of which require us to view the facts in the same light. However, to give context to the parties’ arguments, we provide the following summary of the historical and procedural facts, none of which seem to be in material dispute. Plaintiff and his wife flew from Minnesota to Portland for their granddaughter's wedding. After landing at PDX, plaintiff went to a baggage carousel to retrieve their luggage. Plaintiff removed a suitcase from the carousel and placed it next to him. Plaintiff then reached for a second bag coming around on the carousel, but, as he did so, he tripped over the first bag, which caused him to fall. When plaintiff fell, his right foot was thrust upward against the underside of the baggage carousel and, as a result, he suffered a deep cut to his foot. Plaintiff's injury required surgery, a three-day stay in the hospital, and roughly three months of recovery.

Following the accident, plaintiff sued defendant Port of Portland, which owns and operates PDX. Among other things, plaintiff alleged that "a sharp metal edge on the baggage carousel housing" had "severely lacerated" his right foot. Plaintiff further alleged that the presence of the metal edge had created a dangerous condition and unreasonable risk of harm of which defendant had known or should have known. At trial, plaintiff acknowledged having known that there was a space beneath the carousel "to stick your toes under if you were reaching over to get a bag." He denied, however, being aware of the character of the base of the carousel, such as the material or thickness of the trim. Plaintiff contended that defendant had been negligent and was liable for his injury because defendant had violated its duty to make the premises safe for its business invitees, including airline passengers. An expert witness who testified on plaintiff's behalf acknowledged that the force generated by his fall had contributed to the severity of his injury. Plaintiff maintained, however, that, because the sharp edge was a dangerous condition and posed an unreasonable risk of harm, defendant had been negligent in failing to warn invitees of its presence and allowing it to remain. In its defense, defendant disputed that the edge of the carousel had been sharp and attributed plaintiff's injury to the blunt force created by his negligent fall. More significantly for purposes of this appeal, defendant asserted as part of an affirmative defense of comparative negligence that plaintiff's own negligence had caused, in whole or in part, the injury that he had sustained.

At trial, plaintiff raised various challenges to defendant's assertion of comparative fault as an affirmative defense. Plaintiff first moved to exclude evidence of the defense and sought to have it stricken, arguing that his duty as an invitee was to take reasonable care to avoid conditions of which he was aware or should be aware, which, he contended, did not include the condition of the carousel. He later made essentially the same argument when arguing about jury instructions, and again when moving for a directed verdict as to the defense, objecting to the verdict form, moving for judgment notwithstanding the verdict (JNOV), and seeking a new trial. Each time, the trial court rejected plaintiff's argument that the jury should not be permitted to consider defendant's comparative-fault defense and that, even if the jury could consider comparative fault, his own negligence in tripping over his suitcase was immaterial to that defense.

In instructing the jury at the close of evidence, the trial court gave a series of instructions explaining premises liability, the duty that a possessor of land owes to its invitees, the duty of an invitee, comparative negligence, causation, and foreseeability. Over plaintiff's objection, the court instructed the jury regarding an invitee's duty as follows:

"COMPARATIVE NEGLIGENCE (INVITEE)

"An invitee is required to exercise reasonable care to avoid harm from a condition on the premises of which the invitee knows or, in the exercise of reasonable care, should know. A person has a duty to keep and maintain a reasonable lookout and control over bodily movements, for their own safety.

"In determining and comparing negligence, if any, you must consider the obviousness of danger and the ease or difficulty with which harm to the plaintiff from that danger could be avoided by either party."

(Boldface omitted.) Plaintiff objected to that instruction on the ground that it misstated the law and was not supported by the evidence. He argued that the requirement in the first paragraph, that a person "keep and maintain a reasonable lookout and control over bodily movements, for their own safety" (the lookout instruction), and the entire second paragraph were inappropriate notwithstanding our decision in Vandeveere-Pratt v. Portland Habilitation Center , 242 Or. App. 554, 556, 259 P.3d 9 (2011), which defendant had cited in support of the instruction. Additionally, he argued that the lookout instruction improperly revived the concept of implied assumption of the risk, a defense that the legislature has abolished in Oregon. Defendant's overarching objection to the instruction was, as noted, the same as his argument throughout the trial, namely, that, because he did not know and could not know about the dangerous condition that injured him, he could not be comparatively at fault for his injury. Notwithstanding plaintiff's arguments, the trial court gave the disputed instruction in its entirety.

As to comparative negligence, generally, the trial court gave an instruction that closely tracked the combined language of UCJI 21.01 and UCJI 21.02 (which themselves purport to implement ORS 31.600 ) as follows:

"COMPARATIVE NEGLIGENCE

"The law provides for comparative negligence. This means that you are to determine each party's negligence, if any. You will have one verdict form, which I will explain to you.

"The plaintiff and the defendant have each alleged that the damage was caused by the other's fault. If you find that both the defendant and the plaintiff were at fault and that their fault caused the alleged damage, then you must compare the fault of the plaintiff to the fault of the defendant.

"In making this comparison, you must measure the percentage of fault of each and not the percentage of damage caused by each.

"The comparison of fault must be expressed in terms of percentages that total 100 percent. If the plaintiff's fault is more than 50 percent, then your verdict is for

the defendant. On the other hand, if the plaintiff's fault is 50 percent or less, then your verdict is for the plaintiff.

"Do not reduce the amount of the plaintiff's damages, if any, as a result of your comparison. I will reduce the amount of your verdict by the percentage of the plaintiff's fault, if any."

(Boldface omitted.) Although plaintiff challenged defendant's assertion of any comparative-fault defense, he did not—and does not—dispute that, to the extent that the defense was available, the instruction that the court gave correctly stated the law.

The jury returned a defense verdict that included several special findings. First the jury found that defendant was at fault "in one or more of the ways" asserted by plaintiff; the jury further found that defendant's fault had been a cause of plaintiff's damages. However, the jury also found plaintiff at fault for his injury and found that, like defendant's fault, plaintiff's fault had been a cause of his damages. Based on its findings, the jury returned a verdict in favor of defendant, specifically finding plaintiff 51 percent at fault for his injury and defendant 49 percent at fault. In light of that result, the trial court dismissed plaintiff's claims with prejudice.

II. THE PARTIES’ ARGUMENTS ON APPEAL

Plaintiff now appeals the dismissal of his claims. In his first assignment of error, he argues that, as a matter of law, the trial court improperly allowed the jury to consider his conduct in falling over his own bag as a basis for comparative fault. He emphasizes that, because this is a premises-liability case involving a possessor of land and a business invitee, the duties of each party are defined by their special relationship. Plaintiff asserts that, for two reasons, he cannot be deemed to share fault for his injury in this case. First, plaintiff argues, because defendant was shown to have been aware that invitees sometimes fall when collecting their luggage, defendant was responsible for providing reasonably safe premises to account for that foreseeable occurrence. Second, he argues, his failure to avoid tripping over his own bag was wholly independent of the dangerous condition at issue and, therefore, he could not have violated any duty in regard to that condition. Plaintiff reasons that, because his only duty as an invitee was to exercise reasonable care with respect to conditions of which he was aware or should have been aware—and it is undisputed that he had no reason to know of the sharp edge at the base of the carousel—no fault can be attributed to him for encountering that dangerous condition.

Plaintiff observes that this case raises a novel issue under Oregon law because, unlike the typical premises-liability case involving a comparative-fault defense, plaintiff's alleged negligence in this case was not that he had unreasonably failed to avoid or appreciate the specific instrumentality of his harm, namely, the sharp metal edge at the bottom of the baggage carousel; rather, defendant's theory was that plaintiff's negligence in tripping over his bag had "brought him" to that allegedly dangerous condition. However, plaintiff analogizes his case to Son v. Ashland Community Healthcare Services , 239 Or. App. 495, 244 P.3d 835 (2010), rev. den. , 350 Or. 297, 255 P.3d 489 (2011), a case in which the plaintiff's negligent drug overdose led her to an emergency room visit where she allegedly received negligent care. Plaintiff views our decision in Son as "highly instructive" due to its holding that a patient who negligently injures herself remains entitled to nonnegligent medical care. Plaintiff observes that, as in Son , the parties in this case were in a special relationship that defined their duties, and that, in each case, the negligent actions of the plaintiff "brought" him or her to the negligence of the defendant. Plaintiff reasons that, just as the plaintiff in Son was entitled to nonnegligent medical care even though her own negligence had occasioned her need for care, he was similarly "entitled to a subsequently safe premises" in which to fall when he negligently (but, from defendant's perspective, foreseeably) tripped in defendant's baggage-claim area.

Plaintiff characterizes his argument under his second assignment of error as an alternative to his first, but, as noted, his second argument assumes the correctness of his assertion that he can bear no fault in relation to a condition of which he could not have been aware; in other words, the premise of his first assignment of error. From that premise, plaintiff argues that, even accepting that his negligence in tripping over his own suitcase could theoretically be weighed against defendant's negligence in failing to provide a safe baggage-claim area, it should not have been here, because there was no evidence that he knew or should have known of the dangerous condition that caused his injury. That is, whether or not he behaved negligently in the abstract, the record was insufficient to support a jury finding that he was negligent or otherwise at fault in regard to that condition.

In response to plaintiff's first assignment of error, defendant argues that plaintiff's formulation of the duties associated with premises liability transforms a possessor of land into an insurer of business invitees. Defendant asserts that, regardless of the duties that the parties’ special relationship may define, an invitee's reasonable care for his or her own safety is always relevant to determining whether the invitee shares responsibility for injuries suffered on another's premises. In defendant's view, the Son case is inapposite because, defendant reasons, the decedent in Son suffered two distinct injuries, one of which resulted solely from the defendants’ negligent care, whereas, here, plaintiff suffered a single injury due to the combined fault of the parties. As to plaintiff's second assignment of error, defendant does not dispute that plaintiff did not know and could not have known of the condition at the base of the carousel, but contends that it was not required to prove that fact in light of plaintiff's established negligence in tripping over his suitcase.

III. STANDARD OF REVIEW

As we have noted, plaintiff's appeal implicates multiple standards of review. However, as to at least plaintiff's first assignment of error, his argument on appeal effectively reduces to an assertion that the trial court erred in allowing the jury to consider the affirmative defense of comparative fault as articulated in the trial court's instructions to the jury. In other words, if the court did not commit reversible error in instructing the jury as it did, then plaintiff's first assignment of error necessarily fails. Thus, we turn our attention to that question. First, however, we set out the various standards of review applicable to assertions of instructional error.

"As a general rule, parties in a civil action are entitled to jury instructions on their theory of the case if their requested instructions correctly state the law, are based on the current pleadings in the case, and are supported by evidence." Vandeveere-Pratt , 242 Or. App. at 557-58, 259 P.3d 9 (internal quotation marks omitted). In order to be a correct statement of law, the instruction must be "complete and accurate in all respects." Sloan v. Providence Health System-Oregon , 282 Or. App. 301, 312, 386 P.3d 203 (2016), aff'd , 364 Or. 635, 437 P.3d 1097 (2019). Because plaintiff contends that the instruction that the trial court gave regarding an invitee's duty was erroneous, "we review the given instruction to determine whether it probably created an erroneous impression of the law in the minds of the jurors that affected the outcome of the case." Moorehead v. TriMet , 273 Or. App. 54, 64, 359 P.3d 314 (2015), rev. den. , 358 Or. 550, 368 P.3d 25 (2016). When making that assessment, we do not review the instruction in isolation; rather, we review the instructions in their entirety to determine whether, as a whole, they correctly stated the law. State v. Hogevoll , 348 Or. 104, 108, 228 P.3d 569 (2010). Finally, instructional error does not, itself, warrant a reversal. Instead, we will only reverse if the error "substantially affected a party's rights." Vandeveere-Pratt , 242 Or. App. at 558, 259 P.3d 9 (internal quotation marks omitted). As relevant to this appeal, " ‘[w]hen a trial court incorrectly instructs the jury on an element of a claim or defense and when that incorrect instruction permits the jury to reach a legally erroneous result, a party has established that the instructional error substantially affected its rights.’ " Id. (quoting Wallach v. Allstate Ins. Co. , 344 Or. 314, 329, 180 P.3d 19 (2008) ).

IV. ANALYSIS

A. Premises Liability, Generally

Generally speaking, the duties owed by a possessor of land and a business invitee are discrete concepts. A possessor of land is required to discover conditions of the premises that create an unreasonable risk of harm and either eliminate those conditions or warn foreseeable invitees to enable them to avoid harm. Maas v. Willer , 203 Or. App. 124, 129, 125 P.3d 87 (2005), rev. den. , 340 Or. 411, 134 P.3d 169 (2006). Notwithstanding that duty to its invitees, a possessor of land does not take on the role of "an insurer against accidents upon the premises even as to persons whom they have invited to enter." Hagler v. Coastal Farm Holdings, Inc. , 354 Or. 132, 141, 309 P.3d 1073 (2013) (internal quotation marks omitted). Consistent with that principle, a business invitee must exercise reasonable care to avoid harm from known conditions or those that should be known to the invitee. Maas , 203 Or. App. at 129, 125 P.3d 87.

In determining whether and to what extent a possessor of land is liable for injuries caused by a condition on the land, the jury must compare each party's relative fault for the invitee's harm. ORS 31.600 (providing that fault attributable to a plaintiff is not a bar to recovery if it does not exceed the combined fault of all other contributors, but requiring damages to be "diminished in the proportion to the percentage of fault attributable to the" plaintiff). However, in assessing fault in the first instance, the jury must determine each party's fault, if any, without reference to the other party. Woolston v. Wells , 297 Or. 548, 556, 687 P.2d 144 (1984) ("The comparison of the parties’ fault will only be meaningful if each party's fault is determined without reference to the other party * * *."). As the Supreme Court explained in Woolston ,

"if the jury were instructed that [a] plaintiff is at fault for his own injury if he should expect that a reasonable land occupier would not have discovered the danger or would fail to protect entrants against it, the impropriety is apparent. We hold that it is no less improper to define [a] defendant's liability in these same terms."

Id. ; see also Vandeveere-Pratt , 242 Or. App. at 562, 259 P.3d 9 (explaining that, because the doctrine of assumption of risk has been abolished, "a plaintiff's actions are no longer relevant to the defendant's duty of care" in the premises-liability context).

In discussing how the 1971 abolition of contributory negligence as a complete bar to recovery affected the duties between a possessor of land and a business invitee, the Supreme Court stated:

"Where the issues of fact are framed by allegations of a defendant's negligence, defendant's denial thereof and defendant's affirmative defense of negligence on the part of the plaintiff, the instructions should be framed so as to present the issues in terms of the negligence of each party rather than in terms of liability. Each party is held to the same standard of care with respect to common law negligence. Negligence is conduct falling below the standard established for the protection of others, or oneself, against unreasonable risk of harm . The standard of care is measured by what a reasonable person of ordinary prudence would, or would not, do in the same or similar circumstances.

"In general, it is the duty of the possessor of land to make the premises reasonably safe for the invitee's visit. The possessor must exercise the standard of care above stated to discover conditions of the premises that create an unreasonable risk of harm to the invitee. The possessor must exercise that standard of care either to eliminate the condition creating that risk or to warn any foreseeable invitee of the risk so as to enable the invitee to avoid the harm.

"The invitee is required to exercise that same standard of care in avoiding harm from a condition of the premises of which he knows, or, in the exercise of that standard of care, of which he should know."

Woolston , 297 Or. at 557-58, 687 P.2d 144 (internal citation omitted; emphasis added).

Since Woolston , Oregon courts have adhered to that understanding of an invitee's duty of care. See Garrison v. Deschutes County , 334 Or. 264, 278, 48 P.3d 807 (2002) ; Maas , 203 Or. App. at 129, 125 P.3d 87. However, no decision has expressly addressed whether, for purposes of a comparative-fault analysis, an invitee can always be held accountable for failing to exercise "the standard established for the protection of others, or oneself, against unreasonable risk of harm," or, instead, only when the invitee fails to exercise that degree of care with respect to avoiding harm from conditions on the premises of which the invitee is or should be aware.

B. Son v. Ashland Community Healthcare Services

As mentioned above, plaintiff analogizes his case to our decision in Son . Although we agree that Son provides some helpful guidance, we view that case somewhat differently than plaintiff does. Because it is central to plaintiff's argument on appeal, we explore that decision in some detail.

Son was a wrongful death case. 239 Or. App. at 498, 244 P.3d 835. In that case, after returning home from a party at which she had consumed alcohol and cocaine, the sixteen-year-old decedent, Sara, ingested an unknown quantity of prescription pills, including some leftover medications that her father, Burns, had stored in a box in the garage. Id. at 498-99, 244 P.3d 835. We described the ensuing events as follows:

"The next morning Sara was incoherent, uncoordinated, and vomiting. Burns took her to the emergency room at Ashland Community Hospital at approximately 11:00 a.m. At the time of her arrival, there remained confusion as to both the identification and quantity of the substances that Sara had taken. The hospital records indicate that Sara informed a nurse that she had consumed some alcohol and cocaine at the party. In addition, Burns's fiancée and Sara's friend gathered loose pills and empty pill bottles from the house and took them to the hospital. One of the empty pill

bottles was labeled as Propacet, which is a medication containing acetaminophen and propoxyphene.

"Defendant Rostykus was the emergency room physician at the time of Sara's admission. He initially administered Narcan to combat any narcotics in her system and diagnosed Sara with acetaminophen toxicity related to a polydrug overdose. He suggested that she be admitted to the hospital for n-acetylcysteine treatment for acetaminophen toxicity and continued monitoring for a narcotic overdose. He provided her care until approximately 2:00 p.m. when Sara was transferred to the Intensive Care Unit (ICU) and responsibility for her care shifted to defendant Delgado. Delgado monitored Sara, but her condition quickly deteriorated around 5:00 p.m., and she died shortly thereafter. The Oregon State Medical Examiner and the Jackson County Medical Examiner listed the official cause of death as "sudden cardiac arrhythmia due to propoxyphene overdose."

Id. Following Sara's death, her mother filed a wrongful death action alleging, in part, that Sara's doctors had provided negligent treatment resulting in her death. Id . at 499, 244 P.3d 835.

In response, the defendants raised several comparative-fault affirmative defenses, including allegations that Sara had caused or contributed to her own death by consuming the various substances that she had and by failing to accurately tell her family, the nurses, or the defendant doctors what substances she had consumed and when and in what amount she had consumed them; defendants further alleged that Burns was comparatively at fault for failing to take "adequate preventative measures" in light of a previous suicide attempt by Sara that Burns knew about. Id . at 499-500, 244 P.3d 835. The trial court subsequently granted the plaintiff's motion to strike the defense related to Sara's consumption of substances, but it allowed the "failure to tell" defense to go forward; it also denied the plaintiff's motion to strike, as legally defective, the comparative-fault allegation as to Burns. Id . at 500, 244 P.3d 835. At the conclusion of trial, the jury returned a verdict for the plaintiff, but, based upon the jury's findings, the court reduced the damages award by 25 percent attributable to Sara's fault in failing to tell and 15 percent attributable to Burns's fault related to Sara's earlier suicide attempt. Id . at 501, 244 P.3d 835. The plaintiff appealed the trial court's rulings allowing the jury to consider the defendants’ affirmative defenses regarding Sara's "failure to tell" and Burns's alleged negligence; the defendants cross-appealed the court's ruling striking their affirmative defense regarding Sara's consumption of substances. Id . at 502, 244 P.3d 835. As to Sara's alleged failure to tell, we rejected the plaintiff's argument that, because nothing indicated that the defendants would have done anything differently had they known the details of Sara's Propacet ingestion, the evidence was insufficient to establish that her failure to tell had caused or contributed to her death. Id . at 502-04, 244 P.3d 835. As to that defense, we concluded that there was evidence from which the jury could find that Sara had failed to inform the defendants of her Propacet ingestion and that, had she done so, the defendants could have tailored her treatment appropriately and saved her life. Id . at 505, 244 P.3d 835. Accordingly, the trial court had not erred in allowing that defense to go to the jury. Id.

As to the affirmative defense based on Sara's preadmission conduct, we broadly stated that "conduct by a patient that created the condition that required medical care in a medical malpractice action [cannot] constitute an affirmative defense." Id . at 505, 244 P.3d 835. In the course of reaching that conclusion, we observed that medical malpractice actions fall under a special category of negligence claims involving a "special relationship between the plaintiff and the defendant." Id . at 506, 244 P.3d 835 ; see also Fazzolari v. Portland School Dist. No. 1J , 303 Or. 1, 17, 734 P.2d 1326 (1987) (discussing Oregon's adherence to the common-law concept of duty in special relationship cases). In such cases, a professional providing care to another has a duty to "meet the standard of care used in the reasonable practice of the profession in the community." Son , 239 Or. App. at 506, 244 P.3d 835 (internal quotation marks omitted). And, we emphasized, "the focus in a medical malpractice case is on the injury caused by the negligent treatment, not the original injury that created the need for the treatment." Id . at 508-09, 244 P.3d 835.

Notwithstanding that focus on a defendant's duty in "special relationship" cases, we did not reject out of hand the possibility that a plaintiff could be comparatively at fault in such cases. Rather, we began by describing the general rule as follows:

"[T]he Fazzolari standard, as applied in comparative fault cases, has been stated as whether the facts of the case indicate that the plaintiff ‘took some action or failed to take some action which a reasonable person could have foreseen would increase the risk of harm to the plaintiff, and that the plaintiff did indeed suffer harm of the type which could have been foreseen ***.’ "

Id . at 507, 244 P.3d 835 (quoting Dahl v. BMW , 304 Or. 558, 563, 748 P.2d 77 (1987) ). Then, after acknowledging that we had not previously considered whether a comparative-fault affirmative defense was available in the medical malpractice context, we recognized that there was no reason that it should not be, for the simple reason that medical malpractice cases were, ultimately, simply another "form of negligence." Son , 239 Or. App. at 509, 244 P.3d 835. We continued: "[A]nd, in the negligence context, findings of comparative fault can be based on the plaintiff's failure to take reasonable measures which might have prevented or reduced the injury caused by the defendant's negligence." Id . (first emphasis added; second emphasis in original; internal quotation marks omitted). However, to establish such a defense in a medical malpractice suit, a defendant would have to show "that the plaintiff's negligent conduct relate[d] and contribute[d] to the negligent treatment, because it is the negligent treatment that causes the injury that is at issue." Id . (emphasis added); see also id . at 510, 244 P.3d 835 ("[A]s a matter of law, conduct that merely creates the need for medical treatment cannot cause the type of harm at issue in medical malpractice cases—the injury resulting from the malpractice." (Emphasis added.)). Applying that standard to the defendants’ allegations about Sara's preadmission conduct, we held that the trial court had properly stricken that affirmative defense. Id . at 512, 244 P.3d 835. C. Application

We glean from our decision in Son and related case law several relevant principles. First, the fact that the duties of the respective parties are defined by their special relationship does not, for that reason alone, preclude a defendant from relying on ordinary principles of comparative fault as a defense. See id . at 509, 244 P.3d 835 (recognizing professional malpractice as "a form of negligence" and therefore a context in which a comparative-fault defense may be raised). And, although plaintiff argues that it was defendant's duty to make its premises safe even in light of the foreseeable negligence of its invitees—and contends that his own duty was limited to conditions of which he was aware or should have been aware—he correctly refrains from contending that his status as an invitee wholly excused him of his own duty of care. See Woolston , 297 Or. at 558, 687 P.2d 144 ("The invitee is required to exercise that same standard of care in avoiding harm from a condition of the premises of which he knows, or, in the exercise of that standard of care, of which he should know."); cf. Bowlds v. Taggesell Pontiac Co. , 245 Or. 86, 95, 419 P.2d 414 (1966) (stating, before contributory negligence was abolished as a complete defense, that "[t]he law which requires a plaintiff to exercise the measure of care for his own safety that would be exercised by a reasonably prudent person for his own safety in the same or similar circumstances does not change merely because the plaintiff is an invitee").

Second, although the question of whether a defendant has breached the duty imposed by a special relationship must, as plaintiff emphasizes, be evaluated "without reference to the other party," Woolston , 297 Or. at 556, 687 P.2d 144, a defendant's special duty towards a particular plaintiff does not require the jury to disregard the plaintiff's negligence, even where the defendant knows or has reason to know that persons in the plaintiff's position sometimes behave negligently. The plaintiff in Son argued that there was no evidence to support an argument that the decedent's negligence in failing to tell her providers what she had consumed had caused or contributed to her death; that, according to the plaintiff, was because the evidence established that "overdose patients are not reliable reporters of what and how much they have consumed." 239 Or. App. at 503, 244 P.3d 835. In essence, the plaintiff's contention was that, because that decedent's treatment providers should have anticipated that she would fail to exercise reasonable care for her own safety in that manner, the decedent's foreseeable behavior could not be attributed to the plaintiff in a comparative-fault analysis. Having at least implicitly rejected that argument in Son by upholding the allowance of the defendants’ "failure to tell" defense, we expressly reject plaintiff's analogous argument here that defendant's affirmative defense was foreclosed because defendant knew or should have known that plaintiff would fail to exercise reasonable care for his own safety while claiming his bags. Cf. Gardner v. OHSU , 299 Or. App. 280, 286-87 & n 3, 450 P.3d 558 (2019), rev. den. , 366 Or. 292, 461 P.3d 222 (2020) (distinguishing, in a wrongful death action against mental-health providers following decedent's suicide, certain custodial circumstances in which a care provider has assumed an affirmative duty of self-care for a patient or inmate).

Third, although an owner or possessor of premises may raise a comparative-fault defense even when it has reason to believe that some of its invitees will behave negligently in some way, the invitee's fault must "relate and contribute" to the defendant's actionable conduct. Son , 239 Or. App. at 509, 244 P.3d 835 ("[T]he plaintiff's negligent conduct must relate and contribute to the negligent treatment, because it is the negligent treatment that causes the injury that is at issue."). Thus, in terms of plaintiff's claim that a sharp metal edge on the housing of defendant's baggage carousel created an unreasonably dangerous condition, the relevant question here is whether the trial court properly limited the jury's consideration to any fault on plaintiff's part that may have related and contributed to the danger presented by the trim, because it was allowing that alleged condition to exist that formed the basis of defendant's liability.

So stated, those principles expose the flaw in plaintiff's principal argument on appeal. As noted above, at the root of each of plaintiff's assignments of error is his contention that, as a matter of law, the jury could consider defendant's affirmative defense of comparative fault only if there was evidence to show that he knew or should have known of the alleged dangerous condition. That is, each of plaintiff's various challenges to the evidence that the jury heard, to how it was instructed, to the denial of his motion for a directed verdict, and to the trial court's other rulings is premised on plaintiff's erroneous understanding that defendant was required to establish that plaintiff knew or should have known of the condition of defendant's baggage carousel before the jury could consider defendant's affirmative defense. We do not read our case law to support such a requirement. As a result, plaintiff's principal argument, based, as it is, upon there being such a requirement, cannot succeed.

We turn finally to the one argument plaintiff raises that does not depend on the success of his principal argument. Plaintiff objected to the second sentence of the court's "Comparative Negligence (Invitee)" jury instruction. That instruction, to which plaintiff objected, states the lookout instruction as follows: "A person has a duty to keep and maintain a reasonable lookout and control over bodily movements, for their own safety." Plaintiff contends that that instruction revives the abolished doctrine of implied assumption of the risk and is impermissible under our premises-liability decision in Vandeveere-Pratt . In that case, the plaintiff fell and injured herself when, despite the placement of warning markers, she walked and slipped on a recently mopped floor. 242 Or. App. at 556, 259 P.3d 9. After the jury returned a defense verdict, the plaintiff appealed and assigned error to the following instruction:

"It is the continuing duty of a person to keep and maintain a reasonable lookout for their *** own safety.

A reasonable lookout means such as would be maintained by a reasonably prudent person under the same or similar circumstances.

"In determining this question, you should take into consideration the extent

or degree of danger reasonably to be expected. A person does not comply with the duty to keep a reasonable lookout by simply looking and not seeing that which is plainly visible and would have been seen by a reasonably prudent person under the same or similar circumstances."

Id. at 561, 259 P.3d 9. In Vandeveere-Pratt , we declined the plaintiff's invitation to wholly disavow the lookout instruction; we rejected its use there, however, because, under the circumstances in which it had been given, it would have suggested to the jury "that the plaintiff's failure to maintain a proper lookout excuse[d] the defendant from any liability because the plaintiff assumed the risk of injury." Id. at 564-65, 259 P.3d 9. We identified "at least two reasons [that] the jury could have understood the lookout instruction as excusing defendant's breach of its duty rather than as explaining defendant's allegations that plaintiff was herself negligent." Id. One, because the trial court had given the lookout instruction well after instructing the jury on comparative fault and the lookout instruction emphasized the plaintiff's duty, the "jury could have believed that the instruction as a whole related to plaintiff's right to recovery rather than to an examination of plaintiff's comparative fault." Id. at 565, 259 P.3d 9 (emphasis added). Two, the instruction's second paragraph "suggested that, because plaintiff did not see the warning markers, plaintiff was fully at fault for her injury and could not prevail." Id. As a result, the trial court had erroneously given the lookout instruction in that case. Id.

In plaintiff's case, the trial court's lookout instruction did not suffer the same infirmities as the instruction in Vandeveere-Pratt . First, it was given immediately after the general comparative-fault instruction and, indeed, was captioned as relating to comparative fault, not solely plaintiff's fault. Second, the text of the instruction itself contemplated a comparison of the parties’ respective degrees of fault, in that it referred to the jury's task of "determining and comparing negligence" and the extent to "which harm to the plaintiff from [the] danger could be avoided by either party ." (Emphases added.) Accordingly, the trial court did not err in giving the lookout instruction for any reason identified in Vandeveere-Pratt .

V. CONCLUSION

Business invitees must always exercise reasonable care for their own safety when on premises of others. Notwithstanding that duty, an owner or occupier of premises has a separate duty to maintain reasonably safe premises for its invitees, and neither an invitee's duty of care nor a failure to exercise it absolves the owner or occupier of its own duty. However, an invitee's failure to exercise reasonable care for his or her own safety may be the basis of a comparative-fault defense if the invitee's negligence relates and contributes to the harm or risk of harm created by the defendant's negligence. Under those circumstances, whether the plaintiff knew or could have known that an alleged dangerous condition was on the premises is not determinative. Plaintiff's contention otherwise, which is central to each of his assignments of error, therefore fails. Accordingly, we affirm.

Affirmed.
