McCathern v. Toyota Motor Corp.

The primary issue on review in this product liability civil action is whether plaintiff introduced sufficient evidence to establish that the 1994 Toyota 4Runner was designed defectively. 1 Plaintiff was injured when the 1994 4Runner vehicle in which she was riding as a passenger rolled over. Plaintiff sued defendants — the manufacturer, distributor, and seller of the 4Runner — alleging that the 1994 4Runner was dangerously defective and unreasonably dangerous because its design rendered it unstable and prone to roll over. A jury returned a verdict in favor of plaintiff and awarded noneconomic damages totaling $2,250,000 and economic damages totaling $5,400,000. The Court of Appeals affirmed. McCathern v. Toyota Motor Corp., 160 Or App 201, 985 P2d 804 (1999). We now affirm the decision of the Court of Appeals.

The following facts are taken from the record. We view the evidence, and the reasonable inferences to be drawn therefrom, in the light most favorable to the party in whose favor the jury returned the verdict, i.e., plaintiff. Parrott v. Carr Chevrolet, Inc., 331 Or 537, 542, 17 P3d 473 (2001).

The accident that caused plaintiffs injuries took place one evening in May 1995, when plaintiff and her daughter, together with plaintiffs cousin, Sanders, and her daughter, were riding in Sanders’s 1994 Toyota ¿Runner. Sanders was driving, plaintiff was in the front passenger seat, and the children were in the back seat. Everyone was wearing a seatbelt.

*63 While the group was traveling south on Highway 395 at a speed of approximately 50 miles per hour, an oncoming vehicle veered into Sanders’s lane of travel. 2 Sanders steered to the right onto the paved shoulder to avoid a collision, then steered to the left to stay on the highway, at which point the 4Runner began to rock from side-to-side. She then steered to the right again to return to the south-bound lane, at which point the 4Runner rolled over and landed upright on its four wheels. During the rollover, the roof over the front passenger seat collapsed and, as a result, plaintiff sustained serious and permanent injuries. The other passengers in the 4Runner sustained only cuts and bruises. The vehicle that had veered into Sanders’s lane did not stop, and no other vehicles were involved in the accident.

In January 1996, plaintiff filed the present action against defendants (collectively “Toyota”). 3 Plaintiffs complaint alleged that the 1994 4Runner “was dangerously defective and unreasonably dangerous in that the vehicle, as designed and sold, was unstable and prone to rollover.” 4

At trial, plaintiff presented expert testimony in support of her theory that the 1994 4Runner was designed defectively. One of plaintiffs accident reconstruction experts, Fries, opined that the accident was caused solely by the geometry of the 1994 4Runner, as opposed to any other tripping mechanism, such as braking, off-road travel, or a “rim trip.” 5 Robertson, a statistician specializing in injury statistics, testified regarding the correlation between the height of a vehicle’s center of gravity, its track width, 6 and its rollover *64 resistence. Robertson stated that the 1994 4Runner was unreasonably dangerous because widening the vehicle by only eight inches would have increased its stability and decreased its propensity to roll over. Tamny, another engineer and accident reconstruction expert, also opined that the 1994 4Runner was unreasonably dangerous because the manufacturer could have designed it in such a way that it would have skidded instead of rolling over when making sharp turns on flat, dry pavement.

Beginning with its opening statement and continuing throughout the trial, Toyota conceded that it was aware that the 1994 4Runner rolls over on flat, dry pavement due to tire friction forces alone. According to Toyota, however, the 1994 4Runner’s design was not defective because almost all sport utility vehicles (SUVs) will roll over under conditions similar to those present during plaintiffs accident. 7 Toyota conceded that the design modifications that plaintiffs experts had suggested — lowering the vehicle’s center of gravity or widening its track width to increase rollover resistance — were feasible at the time the 1994 model 4Runner was designed. Toyota argued, however, that those changes were not practicable because they would have diminished the 4Runner’s utility and inhibited its performance in an off-road environment.

Plaintiff also presented evidence that Toyota had redesigned the 1994 model 4Runner in 1996 by lowering its center of gravity and widening its track width. Toyota’s senior staff engineer, Yonekawa, testified that the design modifications made to the 1996 4Runner had improved the vehicle’s handling and rollover resistance. In Toyota’s testing, the 1994 model 4Runner had overturned at speeds of less than 40 miles per hour with steering input alone, i.e., without applying the brakes. By contrast, the 1996 4Runner did not roll over with steering input alone. According to plaintiff s expert, Tamny, “if you have to hit the brakes to make the vehicle unstable, it has better handling characteristics than if you *65 can get it to lift off from steering alone.” Tamny also characterized the 1996 4Runner as a reasonably safe vehicle because, when a driver makes an “obstacle avoidance maneuver” 8 on flat, dry pavement, the 1996 design slides or skids to a stop, and does not roll over. Finally, Dobashi, Toyota’s engineer who was responsible for testing and evaluating the 1996 4Runner, also testified that the 1996 design changes had improved the handling and stability of the 4Runner. When asked whether the 1996 4Runner was worse in any respect than the 1994 model, i.e., whether the design modifications of the 1996 4Runner had affected its utility as an SUV, Dobashi testified that, to his knowledge, “all performances are about the same or better.”

Finally, to counter the argument that no ordinary consumer would expect a 4Runner to stay upright during evasive turns, plaintiff presented evidence that Toyota had promoted the 1994 4Runner as a safe and dependable vehicle for both highway and off-road purposes. Toyota’s national merchandising manager for the United States, Cecconi, testified that Toyota had marketed the 1994 4Runner to older, wealthier drivers who would use the vehicle for commuting as well as for outdoor activities. According to Cecconi, Toyota was aware that many consumers thought that the 4Runner’s height was a safety feature because it allowed better visibility. He also admitted, however, that Toyota’s advertising did not attempt to communicate to consumers the rollover risk attendant with the vehicle’s height. When presented with an example of a television commercial depicting the 4Runner performing evasive maneuvers similar to those that occurred in plaintiffs accident, Cecconi admitted that, under certain conditions, the maneuvers being depicted in the commercial might cause the vehicle to roll over. Cecconi also was shown several Toyota advertising brochures and testified that he was “not really sure” whether the 1994 4Runner safely could perform the evasive maneuvers depicted in the brochures diagrams.

At the close of plaintiffs evidence, Toyota moved for a directed verdict on plaintiffs design-defect claim on two *66 grounds: (1) that plaintiff had failed to prove that the 1994 4Runner was dangerously defective and unreasonably dangerous because she had failed to adduce sufficient evidence of the practicability of her proposed alternative design, viz., the 1996 4Runner; and (2) that plaintiff had failed as a matter of law to prove that the design of the 1994 4Runner had caused her injuries because she had failed to demonstrate that it was more probable than not that the accident and injuries would not have occurred had Toyota manufactured and sold the product with plaintiffs proposed alternative design. The court denied Toyota’s motion on both grounds. Toyota renewed that motion on the same two grounds at the close of the evidence, and the court again denied the motion.

As noted, the jury found for plaintiff, awarding her economic and noneconomic damages. Toyota timely filed a motion for judgment notwithstanding the verdict (JNOV) or, in the alternative, a new trial, based on the same grounds as its earlier motion for a directed verdict. The trial court did not rule on the motion, and it therefore was denied by operation of law. ORCP 63 D; ORCP 64 F.

On appeal, the Court of Appeals concluded that the trial court did not err in denying Toyota’s motions for directed verdict and JNOV because plaintiff had submitted evidence from which a jury could have concluded that the 1994 4Runner had failed to meet ordinary consumer expectations and, therefore, was defective. McCathern, 160 Or App at 204. After reviewing the history of “the controlling standard of strict products liability under Oregon law: the ‘consumer expectation’ test,” id. at 207, the Court of Appeals held that a plaintiff in Oregon could establish defective design by proving ordinary consumer expectations under either a “representational” theory, a “consumer risk-utility” theory, or both. Id. at 218. The court also concluded that plaintiffs proof legally was sufficient under both theories. Id. at 222, 228.

Toyota petitioned for review, renewing its contention that plaintiff had failed to introduce sufficient evidence to support her design-defect claim. We allowed review to consider that issue. Before we reach that issue, however, we consider an additional issue raised in Toyota’s petition for review *67 concerning the trial court’s admission of “other similar incidents” evidence.

At trial, plaintiff presented expert testimony by Wallingford, a forensic engineer specializing in accident reconstruction. Plaintiff had retained Wallingford to review approximately 35 rollover accidents involving pre-1996 Toyota 4Runners to determine whether those accidents were “substantially similar” to plaintiff’s accident. The majority of Wallingford’s testimony was based on information that he had reviewed from lawsuits or investigation reports involving those incidents, including police reports, police photographs, and witness depositions. In some of the cases, Wallingford actually had visited the accident scene or had examined the vehicle involved in the accident. After analysis, Wallingford concluded that approximately 20 of the 35 rollover accidents reviewed were “substantially similar” to plaintiffs accident. 9

In response to Toyota’s objection that the “other similar incidents” evidence was cumulative, and in the interest of time, the court restricted Wallingford’s testimony to 15 incidents. Toyota also objected that the factual information underlying Wallingford’s opinions was inadmissible hearsay. The court overruled that objection and permitted Walling-ford to give a brief summary of each accident for the jury and then to offer his opinion whether each accident was “substantially similar” to plaintiff’s accident based on the criteria that he had identified.

On cross-examination, Toyota sought to impeach Wallingford’s opinion testimony by referring to information contained in several police reports that were part of the factual information on which Wallingford had based his opinions. According to Toyota, those reports had included accident descriptions that directly contradicted Wallingford’s *68 conclusions about the substantial similarity of the other accidents to plaintiffs accident. When Toyota offered those police reports into evidence, plaintiffs counsel objected to their admission on the basis that the reports contained inadmissible hearsay. Defense counsel responded:

“It’s true that the offering attorney may be prevented from putting things into evidence on the grounds that what the expert relied on is hearsay, but that is not true on cross. [0]n cross, the opposite rule applies: If the witness has relied on the information, it is admissible for impeachment purposes, and it’s admissible in the record for that purpose.”

The trial court initially sustained plaintiffs objection. Thereafter, the trial court changed its mind about the hearsay nature of the reports and admitted them into evidence for impeachment purposes. Plaintiff again objected and argued that their admission was prejudicial to her because other information in Wallingford’s file that the court had not admitted, such as deposition testimony, supported Wallingford’s conclusions. In response to that objection, Toyota offered and stipulated to the admission of Walling-ford’s entire file, which included the reports, depositions, and photographs from the 15 accidents. Accordingly, the trial court admitted Wallingford’s entire file into evidence.

On appeal, Toyota argued that the trial court erred when it overruled its hearsay objections and allowed Wallingford’s testimony about the factual information contained in his file on which he based his opinions. The Court of Appeals refused to consider the merits of that argument, because it concluded that Toyota had waived any error on that issue when it subsequently offered and stipulated to the admission of Wallingford’s file. McCathern, 160 Or App at 235-36.

On review, Toyota asserts that the Court of Appeals’ refusal to consider that argument was incorrect because it conflicts with this court’s holding in Wallace v. American Life Ins. Co., 111 Or 510, 533-37, 225 P 192, on reh’g 227 P 465 (1924). Toyota argues that the evidence was inadmissible: (1) because it was hearsay; and (2) because it was unfairly prejudicial. For the reasons set out below, we agree that *69 Toyota did not waive its objection by stipulating to the admission of Wallingford’s file. 10 Nonetheless, we do not agree that the testimony was hearsay or that it was unfairly prejudicial.

We first consider plaintiffs argument that Toyota waived its hearsay objections to Wallingford’s testimony by stipulating to the admission of his file. Toyota is correct that, under Wallace, plaintiffs waiver argument fails. The plaintiff in Wallace argued that the defendant had waived its objections to the plaintiffs expert’s opinion evidence for two reasons: first, because the defendant had “met [the] plaintiffs expert witnesses with expert witnesses and offered ‘opinion evidence’ against ‘opinion evidence,’ ” 111 Or at 533; and, second, because the defendant had cross-examined the plaintiffs expert about the same evidence that, during the direct examination of that expert, the court had admitted and the plaintiff had used over the defendant’s objections, id. at 537. The court in Wallace disagreed with the plaintiffs waiver arguments, explaining:

“The defendant did not waive his objection and exception by attempting to disprove the matters testified to, or to prove facts inconsistent with them. A party excepting to the admission of testimony is not bound to concede its truth, or to refrain from combating it, in order to retain his exception.”

Id. at 536 (internal quotation marks omitted).

The rationale articulated in Wallace is consistent with the general understanding that, when a party’s objection is made and overruled, that party

“is entitled to treat [that] ruling as the ‘law of the trial’ and to explain or rebut, if he can, the evidence admitted over his protest. Consequently, there is no waiver if he cross-examines the adversary’s witness about the matter, even though the cross-examination entails a repetition of the fact, or if he meets the testimony with other evidence which, under the theory of his objection, would be inadmissible.”

*70 Charles Tilford McCormick, McCormick on Evidence, § 55, 246-47 (5th ed 1999) (footnotes omitted). That rationale-applies equally to this proceeding. A party has the right to meet its opponent’s evidence admitted under the trial court’s rulings. After making the proper objections, a party may counter its opponent’s evidence, whether correctly admitted or not, without waiving its evidentiary objection on appeal. Accordingly, Toyota did not waive its hearsay objection by stipulating to the admission of Wallingford’s file. Because no waiver occurred, we turn to Toyota’s argument that the admission of Wallingford’s testimony about the information underlying his opinion was reversible error.

OEC 703 specifies some types of information on which an expert witness may rely for his or her opinion testimony. 11 One source of information provided by OEC 703 is facts or data that are “of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject.” Although the rule specifically provides that such evidence “need not be admissible,” OEC 703 does not render otherwise inadmissible evidence admissible merely because it was the basis for the expert’s opinion.

Nevertheless, we hold that the trial court did not err when it overruled Toyota’s hearsay objections, because plaintiff offered the evidence of the details surrounding the 15 other rollover accidents only to provide the foundation necessary to explain Wallingford’s opinions, not for its truth. The trial court admitted the evidence solely for that purpose. Consequently, by definition, that information was not “hearsay.” See OEC 801(3) (“hearsay” is out-of-court statement offered to prove truth of matter asserted); see also Oberg v. Honda Motor Co., 316 Or 263, 269-70, 851 P2d 1084 (1993) (excerpts of documents read to jury admitted for limited purpose that defendants had notice of defective design and not for truth were not hearsay), rev’d on other grounds sub nom Honda *71 Motor Co. v. Oberg, 512 US 415, 114 S Ct 2331, 129 L Ed 2d 336 (1994).

Toyota also contends that evidence of other similar incidents, including Wallingford’s testimony, 12 , even if otherwise admissible, was unfairly prejudicial under OEC 403 13 and, therefore, should not have been admitted. In support, Toyota argues that the evidence was prejudicial because it “powerfully suggested to the jury that it was the vehicle — not the driver, not the road, not the sudden, hard steering, not the speed, and not the other circumstances — that caused the rollover in this case.” In addition, Toyota argues that the evidence was unfairly prejudicial because some of that testimony included information about injuries or deaths that resulted from those accidents.

We review a trial court’s ruling whether to exclude relevant evidence under OEC 403 for abuse of discretion. State v. Barone, 329 Or 210, 243, 986 P2d 5 (1999), cert den 528 US 1086 (2000). “To be excluded under OEC 403, testimony must be not only prejudicial, but unfairly so.” Id. at 235. Toyota’s assertion that the evidence powerfully suggested that the design of the 1994 4Runner caused the rollover in this case is no more than an assertion that plaintiffs evidence supported her theory of the case. As this court has recognized, relevant evidence often has the effect of proving one party’s position while harming the other’s. See Macy v. Blatchford, 330 Or 444, 455, 8 P3d 204 (2000) (so stating).

The record in this case demonstrates that the trial court complied with OEC 403 by balancing the cost in terms *72 of prejudice of the evidence against its benefits. Oberg, 316 Or at 270-71. The court limited both the number of incidents that Wallingford could discuss and the number of videotaped depositions that plaintiff could present. Additionally, the court did not permit plaintiff to submit detailed evidence of the injuries other people had suffered in other rollover accidents. We conclude that the trial court permissibly could have determined that the probative value of the “other similar incidents” evidence was not substantially outweighed by the danger of unfair prejudice. Accordingly, the trial court did not abuse its discretion in admitting that testimony.

We turn to the primary issue on review, viz., whether plaintiff introduced sufficient evidence to establish that Toyota’s 1994 4Runner was designed defectively. At the outset, we must determine the controlling standard for design defect liability in Oregon and the proof necessary to satisfy that standard.

Before 1979, product liability claims in Oregon were common-law claims. See Wights v. Staff Jennings, 241 Or 301, 405 P2d 624 (1965) (recognizing common-law action for personal injuries resulting from defective product). In 1967, this court expressly adopted Section 402A of the Restatement (Second) of Torts (1965) (Restatement) and its consumer expectations test as the standard for liability in design defect cases. See Heaton v. Ford Motor Co., 248 Or 467, 470, 435 P2d 806 (1967) (adopting Section 402A). Heaton explained that, under Section 402A, a product “is dangerously defective when it is in a condition unreasonably dangerous to the user” and that “unreasonable” in that context means “dangerous to an extent beyond that which would be contemplated by the ordinary consumer.” Id. at 471.

Subsequently, in Phillips v. Kimwood Machine Co., 269 Or 485, 525 P2d 1033 (1974), the court deviated from Heaton’s “pure” Section 402A approach and announced what became known as the reasonable ^Manufacturer test. Unlike the consumer expectations test, \ , lich asks juries to focus on the expectations of the ordinal consumer about product safety, the reasonable manufact ;er test instructs juries to focus on the manufacturer’s mot res for placing the product *73 on the market and on the reasonableness, or lack thereof, of that conduct. Phillips opined:

“A dangerously defective article would be one which a reasonable person would not put into the stream of commerce if he had knowledge of its harmful character. The test, therefore, is whether the seller would be negligent if he sold the article knowing of the risk involved.”

269 Or at 492 (emphasis in original). The court in Phillips acknowledged that Comment i to Section 402A of the Restatement, previously endorsed by the court in Heaton, examines unreasonable dangerousness from a consumer-oriented, as opposed to a seller-oriented, perspective. 14 Id. at 492-93. According to Phillips, however, the two standards— consumer expectations and reasonable manufacturer — substantively were indistinguishable, because an ordinary consumer expects what a reasonable manufacturer would market. Id. at 493. As the court later explained in Ewen v. McLean Trucking Co., 300 Or 24, 706 P2d 929 (1985):

“Clearly the court [in Phillips] regarded a focus on the ‘reasonableness’ of marketing the product, knowing of its dangers, not as a departure from the Restatement’s Comment i but as another way to explain it. In the court’s view, it might be an advantage to bring the definition of a dangerously defective product back into the ‘familiar terms and thought processes’ associated with common law negligence, as indeed this alternative phrasing did[.]”

300 Or at 30-31 (footnote omitted).

The departure in Phillips from the consumer expectations test subsequently was challenged in Allen v. The Heil Company, 285 Or 109, 589 P2d 1120 (1979). The plaintiff in Allen contended that analysis of a design-defect claim necessarily begins with the consumer expectations test of Section 402A of the Restatement and disputed this court’s departure *74 from that approach. Id. at 118-20. In response, this court opined that, because no statute codified Section 402A of the Restatement, the consumer expectations test was binding “only so long and in such particulars” as the court found appropriate. Id. at 119 n 5.

Motivated, at least in part, by this court’s indication in Allen that the court believed that it could exercise considerable discretion in applying Section 402A, the 1979 Legislature codified the law of strict product liability by enacting ORS 30.920. See Ewen, 300 Or at 28 (enactment of ORS 30.920 motivated by desire to “stabilize the rules of [product] liability”); Or Laws 1979, ch 866, § 2. ORS 30.920 provides:

“(1) One who sells or leases any product in a defective condition unreasonably dangerous to the user or consumer or to the property of the user or consumer is subject to liability for physical harm or damage to property caused by that condition, if:

“(a) The seller or lessor is engaged in the business of selling or leasing such a product; and

“(b) The product is expected to and does reach the user or consumer without substantial change in the condition in which it is sold or leased.

“(2) The rule stated in subsection (1) of this section shall apply, even though:

“(a) The seller or lessor has exercised all possible care in the preparation and sale or lease of the product; and

“(b) The user, consumer or injured party has not purchased or leased the product from or entered into any contractual relations with the seller or lessor.

“(3) It is the intent of the Legislative Assembly that the rule stated in subsections (1) and (2) of this section shall be construed in accordance with the Restatement (Second) of Torts sec. 402A, Comments a to m (1965). All references in these comments to sale, sell, selling or seller shall be construed to include lease, leases, leasing and lessor.

“(4) Nothing in this section shall be construed to limit the rights and liabilities of sellers and lessors under principles of common law negligence or under ORS 72.1010 to 72.7250.”

*75 In Ewen, this court interpreted the legislative mandate in ORS 30.920(3) to construe the substantive formulas codified in subsections (1) and (2) “in accordance with the Restatement (Second) of Torts sec. 402A, Comments a to m (1965)” as an enactment of the consumer expectations test. 300 Or at 27, 31-32. Therefore, the court held that, under ORS 30.920, a jury in a design-defect case “should receive some instruction phrased so as to focus on what extent of risk an ordinary consumer would contemplate when purchasing a product with the knowledge of its characteristics common to the relevant community.” Id. at 32.

Plaintiff contends that, when the legislature adopted the consumer expectations test in ORS 30.920, it did so to the exclusion of the reasonable manufacturer test. For the reasons set out below, we agree.

It is true that, in dictum, this court in Ewen stated expressly that it was not resolving the issue whether the reasonable manufacturer test had any continuing relevance in design defect litigation under ORS 30.920. See Ewen, 300 Or at 32 (leaving unanswered whether “any role remains for the [reasonable manufacturer] instruction approved in Phillips”). However, it is clear from the text of ORS 30.920 that the legislature intended to adopt the consumer expectations test. ORS 30.920(3); Ewen, 300 Or at 31-32; see also PGE v. Bureau of Labor and Industries, 317 Or 606, 610, 859 P2d 1143 (1993) (text of statutory provision is starting point for interpretation and best evidence of legislature’s intent). As the court in Phillips acknowledged, the reasonable manufacturer and the consumer expectations tests take different perspectives. Whether we agree with the court’s conclusion in Phillips — that the two tests substantively are equivalent — is of no moment. When it enacted ORS 30.920, thereby codifying the consumer expectations test, the legislature endorsed only one perspective — that of the consumer. We infer from that choice that the legislature did so to the exclusion of the different perspective of the manufacturer. In light of the clear choice embodied in the wording of ORS 30.920, there is no room to argue that the reasonable manufacturer test remains viable. Accordingly, we conclude that the legislature has abrogated the reasonable manufacturer test. Oregon trial *76 courts no longer may instruct juries according to the reasonable manufacturer test instruction approved in Phillips, 269 Or at 501 n 16.

Having concluded that, under ORS 30.920, the consumer expectations test governs design defect cases in Oregon, we now consider the proof necessary to establish that a product fails to meet ordinary consumer expectations as to safety.

The Court of Appeals held that there are “two distinct answers” to the question of how a plaintiff proves ordinary consumer expectations in Oregon:

“[A] plaintiff in a defective design case can, with sufficient proof, proceed under either a ‘representational’ theory, a ‘consumer risk-utility’ theory, or both.”

McCathern, 160 Or App at 218. According to that court, a plaintiff may establish consumer expectations under the “representational” theory

“by proving that the manufacturer specifically represented to the consuming public that the product would be able to perform certain functions, when, in fact, it could not, resulting in the plaintiffs injury.”

Id. at 209. By contrast, the court stated that a plaintiff may establish consumer expectations under the “consumer risk-utility’ theory by proving “that a product could have feasibly and practicably been designed more safely.” Id. at 210.

On review, Toyota’s first complaint is that the Court of Appeals’ decision created, by way of its “representational” theory, a “new theory of product liability” that conflicts with the controlling statute, ORS 30.920, and with this court’s case law. Similarly, plaintiff complains that the Court of Appeals’ decision erroneously converted categories of evidence that are relevant to consumer expectations into separate theories of liability. We agree with plaintiffs characterization of the error and, for the reasons that follow, we reject the Court of Appeals’ conclusion that a product design defect may be proved under two separate and distinct “theories” of ‘liability.

*77 As noted above, the consumer expectations test is the only theory of liability that OES 30.920 expressly mandates. Under ORS 30.920(1), that test requires a plaintiff to prove that the product at issue is both defective and unreasonably dangerous. 15 See also Restatement § 402A, Comment i (liability under 402A attaches only when defective condition of product makes it unreasonably dangerous to user or consumer). The comments to Section 402A of the Restatement define the terms “defective” and “unreasonably dangerous.” See ORS 30.920(3) (ORS 30.920(1) and (2) “shall be construed in accordance with” Restatement Section 402A, Comments a to m). Both definitions refer to the consumer expectations test as the standard for determining whether a product is defective and unreasonably dangerous.

Accordingly, to prove that a product was in a “defective condition unreasonably dangerous to the user or consumer,” ORS 30.920(1), the plaintiff must prove that: (1) “at the time it leaves the seller’s hands, [the product is] in a condition not contemplated by the ultimate consumer, which will be unreasonably dangerous to him,” see Restatement § 402A, Commentg (so defining “defective”); and (2) “[the product is] dangerous to an extent beyond that which would be contemplated by the ordinary consumer who purchases it, with the ordinary knowledge common to the community as to its characteristics,” see Restatement § 402A, Comment i (so defining “unreasonably dangerous”). Whether a product is dangerous to an extent beyond that which would be contemplated by the ordinary consumer is a factual question to be determined by the jury. Heaton, 248 Or at 472-73. It is the trial court’s role, however, to ensure that the evidence is sufficient for the jury to make an informed decision about what ordinary consumers expect. Id.

*78 As noted in Heaton, in some cases, consumer expectations about how a product should perform under specific conditions will be within the realm of jurors’ common experience. Id. at 472. However, some design-defect cases involve products or circumstances that are “not so common * * * that the average person would know from personal experience what to expect.” Id. at 473. When a jury is “unequipped, either by general background or by facts supplied in the record, to decide whether [a product] failed to perform as safely as an ordinary consumer would have expected,” this court has recognized that additional evidence about the ordinary consumer’s expectations is necessary. Id. at 473-74. That additional evidence may consist of evidence that the magnitude of the product’s risk outweighs its utility,
