IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION THREE

PAULA NOVAK,
as Special Administrator, etc.,
Plaintiff and Appellant, A133073

v. (Alameda County
CONTINENTAL TIRE Super. Ct. No. HG07344892)
NORTH AMERICA, INC., et al.,
Defendants and Respondents.

This appeal follows a defense verdict in a case brought by a passenger in a vehicle
who sustained serious injuries after a tire blowout and collision. The passenger, Alex
Novak, brought an action against the tire manufacturer and the mechanic who had
previously serviced the vehicle. Novak stated causes of action for strict product liability
and negligence against the tire manufacturer for failing to provide a warning that tires
degrade with age and should be replaced after about six years even if the tire shows good
tread depth. Novak sued the mechanic for negligence in failing to warn about the danger
of old tires when rotating the tires and performing other maintenance on the vehicle.
Following pretrial evidentiary rulings that excluded some of Novak‟s evidence,
the court granted the tire manufacturer‟s motion for a nonsuit on the strict liability cause
of action and the jury returned a defense verdict for both the manufacturer and the
mechanic on the negligence cause of action. Plaintiff appeals, contending that he was
prejudiced by both evidentiary and instructional errors. We agree that the court

1
prejudicially erred in excluding relevant and admissible evidence and in refusing a jury
instruction necessary to the jury‟s fair consideration of the case, and shall therefore
reverse the judgment.

STATEMENT OF FACTS

On September 12, 2005, Milagros Ibarra was driving her 1988 Chevrolet van upon
a residential street in Fremont with her friend Alex Novak as a passenger in the front seat
when the van‟s right rear tire blew out. The van veered sharply to the right and hit a
telephone pole, crushing the front passenger side of the van. Novak suffered two broken
legs, a punctured lung and other serious injuries. At the time of the accident, Ibarra was
78 years old and Novak was 81 years old.
The tire on Ibarra‟s car was manufactured in 1993; it was 12 years old at the time
of the accident. All tires bear an alphanumeric code on the sidewall identifying the week
and year of manufacture. (49 C.F.R. § 574.5(d) (2005).)

PROCEDURAL HISTORY

Novak sued the tire manufacturer, Continental Tire North American, Inc.
(Continental), and the owner of the automotive repair facility that serviced Ibarra‟s van,
Chi Tai.1 Novak claimed both defendants should have warned Ibarra that tires degrade
with age and are in danger of rupturing even with good tread depth.
Trial proceeded on Novak‟s causes of action for strict liability against Continental
and negligence against Continental and Tai. The court granted nonsuit on the strict
liability claim, and the jury returned a defense verdict on the negligence claims. Novak‟s
motion for a new trial was denied. The court entered judgment for defendants and
awarded them costs of suit. This appeal timely followed.
Novak died during pendency of the appeal and his daughter, acting as special
administrator of his estate, has been substituted as plaintiff.

Ibarra also sued Continental and Tai but reached a pretrial settlement of her claims.

 DISCUSSION

“Strict liability has been imposed for three types of product defects: manufacturing
defects, design defects, and „ “warning defects.” ‟ [Citation.] The third category describes
„products that are dangerous because they lack adequate warnings or instructions.‟ ”
(O’Neil v. Crane Co. (2012) 53 Cal.4th 335, 347.) “ „Generally speaking, manufacturers
have a duty to warn consumers about the hazards inherent in their products. [Citation.]
The requirement‟s purpose is to inform consumers about a product‟s hazards and faults of
which they are unaware, so that they can refrain from using the product altogether or
evade the danger by careful use. [Citation.] Typically, under California law, we hold
manufacturers strictly liable for injuries caused by their failure to warn of dangers that
were known to the scientific community at the time they manufactured and distributed
their product.‟ ” (Id. at p. 351.)
Liability for negligence may also be imposed for a manufacturer‟s failure to warn
of product dangers. “Negligence law in a failure-to-warn case requires a plaintiff to prove
that a manufacturer or distributor did not warn of a particular risk for reasons which fell
below the acceptable standard of care, i.e., what a reasonably prudent manufacturer
would have known and warned about.” (Anderson v. Owens-Corning Fiberglas Corp.
(1991) 53 Cal.3d 987, 1002.)
As for the claim against the mechanic, Tai, “a repair shop or service station
operator is under a duty to exercise ordinary care and skill in repairing motor vehicles.”
(38 Am.Jur.2d (2013) Garages, § 59.) An automobile repair person may be held liable in
negligence for “damages proximately resulting from the negligent or unskillful manner in
which one makes repairs or performs services.” (Id., § 53, fn. omitted.)

3
I. The trial court erred in excluding automobile owner manuals recommending
replacement of tires after five to ten years of service and in precluding plaintiff’s expert
witnesses from relating statements in the manuals and trade publications to support the
opinion that the danger of old tires was known or reasonably knowable in the automotive
industry.

The court granted nonsuit on the strict liability cause of action against Continental
on the ground that plaintiff failed to present sufficient evidence that Continental knew or
should have known of the potential danger that an old tire will rupture. Any deficiency in
this respect was caused by the erroneous exclusion of evidence tending to prove that
Continental should have been aware of this danger.
Plaintiff sought to introduce, as exhibits, trade publications and automobile owner
manuals advising that tires should be replaced after five to ten years, regardless of tread
depth, because rubber degrades with age. Plaintiff also sought to have experts testify that
they relied on these advisements in forming the opinion that defendants should have
known of the danger posed by old tires. Continental filed a motion in limine to exclude
the documents as irrelevant, lacking foundation and more prejudicial than probative. Tai
joined in the motion. The court granted the motion, finding that the documents were
inadmissible hearsay and, secondarily, that the manuals lacked authentication. The court
also precluded plaintiff‟s experts from relating statements contained in the documents. As
we explain below, portions of the manuals advising tire replacement after a certain
number of years were admissible to show industry practice for tire replacement and what
Continental knew or should have known about the potential danger of old tires. The
remaining portions of the manuals and trade publications concluding that old tires are
dangerous was inadmissible hearsay but plaintiff‟s experts should have been permitted to
recite those findings in support of their opinions.
The proffered materials included a 1986 study conducted by the German Motor
Vehicle Inspection Association (known as DEKRA, a German acronym). (Dekra
[as of April 1, 2013].) DEKRA studied tire failures
and noted “a dramatic increase in tires that are older than six years. In this instance, tire
aging and the embrittlement of the rubber is prominent. [¶] Based on the data gathered

4
here it is recommended that, in terms of tire age, tires that are older than six years should
be replaced even if the tread profile is still sufficient.” A 1987 rubber trade publication
found that tire “failure frequency climbs disproportionately fast with increasing tire age.
Based on the data we gathered, the probability of a breakdown due to tire damage is eight
times as high with a nine-year-old tire than with a two-year-old tire—but this is a known
fact among experts in the field.” Plaintiff also proffered numerous automobile owner
manuals, including a 1987 Porsche owner manual that states: “The supposition that tire
durability and performance are immune to the effects of storage and age is unfounded.
Chemical additives which make the rubber elastic lose their effectiveness in the course of
time and the rubber becomes brittle and cracks. . . . [¶] Under no circumstances should
tires older than 6 years be used on your Porsche.”
The trial court excluded these documents from evidence and precluded plaintiffs‟
experts from relaying to the jury the statements contained in them. Plaintiff‟s engineering
expert opined that rubber degrades with age and that the tire in this case ruptured because
it was old. In relying upon the DEKRA study, the expert was allowed to testify only that
the study compiled statistics on 146 tires that showed a high failure rate at ages seven and
eight years and that the expert found the study “supportive” of his opinion. The expert
was not permitted to refer to the study‟s finding that older tires showed “embrittlement of
the rubber” or the study‟s recommendation that tires “older than six years should be
replaced even if the tread profile is still sufficient.” Concerning the automobile owner
manuals, the expert was permitted only to list them among the many materials he relied
upon in forming his opinion and to state that the documents he consulted did not “cause
[him] to doubt [his] conclusions regarding the cause of failure in the subject tire.” The
court‟s exclusionary order was too broad.
“It is often said that a trial court‟s ruling on the admissibility of evidence is vested
in that court‟s discretion and will not be disturbed on appeal unless that discretion was
abused.” (People v. Franzen (2012) 210 Cal.App.4th 1193, 1205.) However, “[a]ny legal
ruling involves three components: the law, the facts, and the application of the law to the
facts.” (Ibid.) “A trial court usually has the preeminent power to determine matters of

5
fact—including, at least provisionally, any „preliminary fact‟ on which an evidentiary
ruling may depend” but “its determination as to the governing legal principles [citation]
is subject to independent appellate review.” (Ibid.) “Thus insofar as the trial court
expressly or impliedly determined the historical facts bearing on admissibility, its ruling
must be upheld so long as it is supported by substantial evidence. But insofar as the court
selected and applied the governing legal principles . . . its ruling is subject to independent
review.” (Ibid.)
A. Authentication
Plaintiff offered to prove authentication of the automobile owner manuals with the
testimony of automobile owners who received the manuals, automobile dealers who
provided the manuals, and others who obtained the manuals from dealers or other
reputable sources. The court questioned the sufficiency of the proffered authentication
evidence, suggesting that a proper foundation required testimony from the manuals‟
authors. The court said authentication was not established “[u]nless you have somebody
[who] can talk about how, when and why” the auto manufacturers issued advisements
about tire replacement in their manuals. This is the position taken by defendants on
appeal. Continental argues that authentication was lacking because plaintiff “offered no
witnesses who could be cross-examined by the defendants regarding the basis for the
information or recommendations contained in any manual.” Continental overstates the
requirements for authentication of a writing.
A written document must be shown to be authentic before it may be admitted in
evidence. (Evid. Code, § 1401; Thorstrom v. Thorstrom (2011) 196 Cal.App.4th 1406,
1418.) “[A] document is authenticated when sufficient evidence has been produced to
sustain a finding that the document is what it purports to be ([Evid. Code,] § 1400). As
long as the evidence would support a finding of authenticity, the writing is admissible.
The fact conflicting inferences can be drawn regarding authenticity goes to the
document‟s weight as evidence, not its admissibility.” (Jazayeri v. Mao (2009) 174
Cal.App.4th 301, 321.)

6
 Authentication of a writing does not require the author‟s testimony. A written
document is authenticated if there is sufficient evidence that the document is “what it
purports to be.” (Jazayeri v. Mao, supra, 174 Cal.App.4th at p. 321.) Authentication of a
writing can be provided by a variety of means; even its contents may be sufficient proof
the document is genuine. (Ibid.) In this case, plaintiff proffered sufficient authentication
by offering testimony to establish that the manuals were, in fact, genuine manuals
distributed by automobile manufacturers to customers buying vehicles. Plaintiff was not
required to obtain the testimony of the individuals who wrote the manuals.
B. Hearsay and Expert Witness Testimony
The hearsay rule was also improperly applied to bar the admission of the
automobile manuals for the limited purpose for which they were offered—notice and
industry practice—and to preclude the expert witnesses from referring to the content of
the manuals and trade publications to support their opinions
Out of court statements are hearsay only when “offered to prove the truth of the
matter stated.” (Evid. Code, § 1200.) Statements in the Porsche and other product
manuals that rubber degrades with age, if offered to prove the truth of those statements,
were properly excluded as hearsay. However, plaintiff offered to limit use of the manuals
to proving defendants had notice of the potential danger posed by old tires rather than
proving that old tires are, in fact, dangerous. The warning contained in the Porsche
manual that “Under no circumstances should tires older than 6 years be used on your
Porsche” and similar manufacturer advisements were not offered to prove the truth of the
statements but to prove that the risks were well known within the industry and should
have been known by the defendants. Manufacturer publications like product manuals and
brochures may be admitted to prove notice. (See Fraijo v. Hartland Hospital (1979) 99
Cal.App.3d 331, 344-345 [warning in drug brochure admissible to show knowledge by
medical personnel charged with malpractice].)
Notice was directly relevant to the litigated claims. An element of the strict
liability cause of action against Continental was that the tire had potential risks that were
known or knowable in light of the scientific knowledge that was generally accepted in the

7
scientific community at the time of sale and that Continental failed to adequately warn
consumers of the potential risks. (CACI No. 1205.) Indeed, the basis upon which the
court granted the nonsuit motion was that this element had not been established.
Warnings against the use of old tires in multiple automobile manuals is evidence that the
risks were known or knowable by Continental when it sold its tire. Similarly, the
negligence claim against Continental required proof that defendant “knew or reasonably
should have known that the [tire] was dangerous or was likely to be dangerous when used
in a reasonably foreseeable manner” and that defendant “failed to adequately warn of the
danger or instruct on the safe use of the [tire].” (CACI No. 1222, italics added.)
“ „Negligence law in a failure-to-warn case requires a plaintiff to prove that a
manufacturer or distributor did not warn of a particular risk for reasons which fell below
the acceptable standard of care, i.e., what a reasonably prudent manufacturer would have
known and warned about.‟ ” (Chavez v. Glock, Inc. (2012) 207 Cal.App.4th 1283, 1305.)
Evidence of automobile manufacturers‟ recommendations for tire replacement was
admissible to prove that a reasonably prudent tire manufacturer would have known about
and warned against the use of old tires.
The manuals were also admissible to prove accepted custom and practices in the
automobile industry concerning tire replacement, which was relevant to the negligence
claim against the automotive repair shop operator. Plaintiff needed to prove that Tai
breached a duty of care in failing to advise the van‟s owner to replace an old tire when
Tai serviced Ibarra‟s van in 2004 and 2005. (CACI No. 401.) Tai admitted knowing that a
tire‟s year of manufacture is encoded on the sidewall. Customs or practices in the
community are properly considered in deciding whether Tai breached a duty of care.
(Burke v. John E. Marshall, Inc. (1940) 42 Cal.App.2d 195, 203-204; CACI Nos. 401,
413.) The tendered product manuals for five different makes of automobiles from 1987 to
2005 recommending tire replacement for older tires contained relevant evidence of
community custom and practice, as well as evidence of notice, and were wrongly
excluded by the trial court.

8
 The court also erred in precluding plaintiff‟s experts from testifying that their
opinion that that the danger of an older tire rupturing was known or should have been
known by Continental was based in part on warnings to that effect contained in both trade
publications and automobile owner manuals. An expert may base opinion testimony on
any matter, “whether or not admissible, that is of a type that reasonably may be relied
upon by an expert in forming an opinion upon the subject . . . . ” (Evid. Code, § 801,
subd. (b).) An expert may also tell the jury the matters he or she relied upon in forming
an opinion (Evid. Code, § 802), although the expert “may not testify as to the details of
such matters if they are otherwise inadmissible” (Grimshaw v. Ford Motor Co. (1981)
119 Cal.App.3d 757, 788-789, italics added). An expert is not permitted to read third
party “reports or documents to which he referred or relate their contents in specific
detail” (id. at p. 789) but is permitted to relate sufficient information from third party
materials to show that the materials provide a basis for his or her opinion. For example,
an expert may describe the nature of consumer complaints about a product and read
portions of those complaints in supporting the opinion that the manufacturer had notice of
product dangers. (West v. Johnson & Johnson Prods., Inc. (1985) 174 Cal.App.3rd 831,
859-862.) In Grimshaw v. Ford Motor Co., supra, at pages 788-789, a product liability
case, the court held that an expert was properly permitted to recite statements from
industry literature and reports to support his opinion that an alternative product design
was safe and feasible. In Jones v. John Crane, Inc. (2005) 132 Cal.App.4th 990, 1004, a
product liability case based on a failure to warn, an expert related statements from
medical journals and other texts linking asbestos and lung cancer. This court held that the
historical literature supported the expert‟s opinion that there was a scientifically known or
knowable probability that defendant‟s product would increase plaintiff‟s risk of cancer.
(Ibid.)
Here, the court improperly prohibited plaintiff‟s experts from supporting their
opinion that the danger of driving on old tires was known or scientifically knowable by
defendants at the relevant dates by relating the warnings and advice contained in trade
publications and product manuals. Subject to a proper limiting instruction, the testimony

9
should have been received to permit the jury to consider the basis upon which the experts
based their opinions. (Kelley v. Bailey (1961) 189 Cal.App.2d 728, 738.)

II. The trial court erred in excluding defendant Tai’s deposition testimony stating that old
tires are dangerous.

Plaintiff also correctly asserts that the trial court erred in excluding Tai‟s
admission that he was aware of the dangerousness of driving on old tires. Tai owned
Peralta Auto Center in Fremont where Ibarra had her car serviced. He also owned a
Unocal 76 gas station and repair facility in San Francisco and had been in the business of
repairing cars for 20 years at the time he rotated the tires on Ibarra‟s vehicle in 2004, a
year before the accident. Plaintiff called Tai as an adverse witness and questioned him
about his shop‟s custom and practice when inspecting tires during a tire rotation. At
several points during the examination, plaintiff‟s counsel read from Tai‟s deposition
transcript. Defendants‟ attorneys objected to a portion of the deposition testimony on the
grounds that it “lacks foundation” and “calls for a hypothetical.” The objection was
sustained with the explanation that the deposition question “calls for expert testimony”
and Tai is not an expert.
The deposition testimony, with the objections and witness statements that were
excluded at trial in italics, was as follows: “Q. Assume a tire looks good in the sense
there‟s no cracks and the tread is good. [¶] A. Yes. [¶] Q. But let‟s say it‟s been stored for
six years or more in some warehouse or shop. [¶] A. Yes. [¶] Q. And then it‟s put on a
car. [¶] A. Yes. [¶] Q. Do you have any information as to whether or not it‟s dangerous to
use a tire that is that old even though it hasn‟t been driven yet? [¶] A. Usually the shop, if
tire inventory about five year, they are not using [sic], they return it back to the
manufacturer or wholesale dealers, yeah. [¶] Q. They‟ll return it? [¶] A. Yeah. [¶] Q. Why
is that? [¶] A. Why? [¶] Q. Yes. [Counsel for Tai]: I am going to object right now, getting
into expert testimony and we haven’t disclosed him as an expert, and you are also posing
hypotheticals in this question. But go ahead. [Counsel for Continental]: I am going to
object to this question based on his knowledge so far. [Counsel for Tai]: Go ahead. Do

10
you know why shops return tires? [¶] A. It’s dangerous. [¶] Q. Did you ever return any on
that basis? [¶] A. Unocal. [¶] Q. You did? [¶] A. Yeah.” (Italics added.)
The trial court erred in excluding this testimony. Tai‟s acknowledgement that
automotive repair shops return a tire that is about five years old because “[i]t‟s
dangerous” and that he had done so himself was not an improper lay opinion divorced
from personal knowledge, as defendants argue. (Evid. Code, § 800.) In the first place,
Tai‟s operation of two automobile repair facilities over a period of some 20 years
qualified him to express an opinion as to common practice in the industry. (Howard
Entertainment, Inc. v. Kudlow (2012) 208 Cal.App.4th 1102, 1119-1121.) More
importantly, Tai testified that he had personally returned old tires because they are
dangerous to use, which was highly relevant to show that he was aware of the danger and
therefore failed to act reasonably in rotating the tires on Ibarra‟s van without warning her
of the danger. Defendants dispute this reading of Tai‟s testimony, noting that Tai‟s
Peralta Auto Center did not store tires but purchased them from a wholesaler as needed.
Defendants argue that Tai was not relating personal experience but speculating about how
a tire warehouse might handle unused inventory. But Peralta Auto Center was not the
only automotive service facility Tai operated. Tai also operated a Unocal 76 service
station, received Unocal training on tire servicing and sold Unocal tires. When asked at
his deposition if he ever returned old tires as dangerous, he answered “Unocal” and then
clarified that, yes, he had returned tires “on that basis.” Fairly interpreted, Tai‟s
deposition testimony reflects Tai‟s personal experience and awareness of the danger of
driving on old tires. The excluded testimony should have been admitted, after which Tai
would have had an opportunity to clarify any ambiguity.

III. The trial court did not err in refusing a special jury instruction on negligent failure to
warn.

Novak requested a special jury instruction on a manufacturer‟s negligent failure to
warn about a product‟s dangerous condition. The requested instruction was as follows:
“ „A manufacturer‟s duty to warn is a continuous duty which lasts as long as the product
is in use.‟ The manufacturer has a duty to issue warnings and instructions after sale „when

11
it later learns of the dangerous propensities of the product.‟ ” Defendants objected to the
instruction, and the court refused it.
Plaintiff has not provided a clear record of the jury instructions that were given to
the jury but it appears that the standard instructions were given, including CACI
No. 1222 that sets out the elements of a cause of action for a manufacturer‟s negligent
failure to warn of product dangers.2 That instruction accurately and fully sets out the
applicable legal principles and plaintiff has failed to demonstrate that the standard
instruction was inadequate in any respect. Standard jury instructions are approved for use
as the “official instructions for use in the state of California” after an exhaustive vetting
process to ensure accuracy, comprehensiveness, and comprehensibility. (Cal. Rules of
Court, rule 2.1050.) Use of these standard instructions “is strongly encouraged.” (Cal.
Rules of Court, rule 2.1050(e).) While unusual circumstances may warrant special
instructions in substitution, or in addition, to standard jury instructions, plaintiff has
failed to demonstrate any reason for which the standard instruction was inadequate in this
case or why it was necessary to give the special instruction he offered, which was
cobbled together from statements taken from two separate court opinions. Modification
of jury instructions to include opinion excerpts should be approached with caution
because an opinion excerpt, even if a correct statement of the law, “does not necessarily
make a good jury instruction.” (People v. Adams (1987) 196 Cal.App.3d 201, 204-205.)
The standard jury instruction fully and fairly apprised the jury of the controlling

2
CACI No. 1222 reads as follows: “[Plaintiff] claims that [defendant] was negligent by
not using reasonable care to warn . . . about the [tire]‟s dangerous condition or about facts
that made the [tire] likely to be dangerous. To establish this claim, [plaintiff] must prove
all of the following: [¶] 1. That [defendant] [manufactured] the [tire]; [¶] 2. That
[defendant] knew or reasonably should have known that the [tire] was dangerous or was
likely to be dangerous when used or misused in a reasonably foreseeable manner;
[¶] 3. That [defendant] knew or reasonably should have known that users would not
realize the danger; [¶] 4. That [defendant] failed to adequately warn of the danger . . . of
the [tire]; [¶] 5 That a reasonable [manufacturer] under the same or similar circumstances
would have warned of the danger . . . of the [tire]; [¶] 6. That [plaintiff] was harmed; and
[¶] 7. That [defendant]‟s failure to warn was . . . a substantial factor in causing
[plaintiff]‟s harm.”

12
principles concerning a manufacturer‟s negligent failure to warn of product dangers and
did not require augmentation with the special instruction proffered by Novak.

IV. The court erred in refusing to instruct the jury on the sudden emergency doctrine.

Alex Novak testified that the van he was riding in struck a telephone pole almost
immediately after he heard a loud bang, which was a tire rupturing. Defendants offered
the testimony of an accident reconstruction expert who opined that the van “was
controllable after the tire deflated” and struck the pole because the driver veered sharply
to the right when she should have steered the vehicle straight ahead and brought it to a
stop with a “light brake application.” The expert testified that “the tire was not a
substantial cause of the vehicle colliding with the pole” and blamed the collision on the
driver, Ibarra, who did “the wrong thing” in steering the van toward the curbside pole.
Plaintiff argued that the tire blowout created a sudden emergency to which Ibarra
reasonably reacted and requested a standard jury instruction, CACI No. 452, on the
sudden emergency doctrine. The court denied the request, finding insufficient evidence to
support the instruction. Plaintiff challenges the court‟s refusal to give the requested jury
instruction.
California has long recognized the sudden emergency doctrine in negligence
cases: “a person who, without negligence on his part, is suddenly and unexpectedly
confronted with peril, arising from either the actual presence, or the appearance, of
imminent danger to himself or to others, is not expected nor required to use the same
judgment and prudence that is required of him in the exercise of ordinary care in calmer
and more deliberate moments.” (Leo v. Dunham (1953) 41 Cal.2d 712, 714.) CACI
No. 452 encapsulates the doctrine and reads: “[Plaintiff] claims that [Ibarra] was not
negligent because she acted with reasonable care in an emergency situation. [Ibarra] was
not negligent if [plaintiff] proves all of the following: [¶] 1. That there was a sudden and
unexpected emergency situation in which someone was in actual or apparent danger of
immediate injury; [¶] 2. That [Ibarra] did not cause the emergency; and [¶] 3. That
[Ibarra] acted as a reasonably careful person would have acted under similar

13
circumstances, even if it appears later that a different course of action would have been
safer.”
The court refused to give this instruction because it found a “lack of evidence
regarding how [Ibarra] felt to determine and for the jury to evaluate whether or not it fell
within the parameters of [CACI No.] 452.” There was no testimony from Ibarra as to her
perception of the accident; she suffered from Alzheimer‟s disease at the time of her
deposition and died before trial commenced. Defendants contend the instruction was
properly refused for the reason stated by the court and that the sudden emergency
doctrine is limited to situations where a party to the action reacted to an emergency.
Defendants contend the doctrine does not apply where, as here, a third party‟s reaction to
an emergency is at issue. The contention is without merit.
The sudden emergency instruction “should be given when the evidence is
sufficient to support the finding of the objective appearance of sudden and unexpected
peril.” (Harris v. Oaks Shopping Center (1999) 70 Cal.App.4th 206, 210, italics added.)
Testimony from the one confronting the claimed emergency is commonly presented but it
is not the only way to prove the existence of an emergency. Here, sufficient prima facie
evidence of an emergency was presented by the physical evidence of a tire blowout and
the testimony of Alex Novak and an independent eyewitness who each testified to a loud
bang followed seconds later by the van veering to the right and striking a telephone pole.
A sudden emergency instruction should be given when there is “evidence which would
permit a reasonable jury to conclude that [emergency] conditions existed.” (Damele v.
Mack Trucks, Inc. (1990) 219 Cal.App.3d 29, 37.) It is then for the jury to decide whether
an emergency actually existed and, if so, whether actions taken in response to the
emergency were reasonable under the circumstances. (Ibid.; accord Leo v. Dunham,
supra, 41 Cal.2d at p. 715.) Evidence of a tire blowout—even when evidence on the
matter is disputed—supports a sudden emergency instruction. (McShane v. Cleaver
(1966) 247 Cal.App.2d 260, 263-264, 268-269.)
Defendants‟ contention that the sudden emergency doctrine applies exclusively to
plaintiffs and defendants who confront emergencies, and not to third parties, is not

14
supported by law or logic. The doctrine broadly applies “where a nonnegligent person is
confronted with a situation of imminent danger to himself or to others, in which case he
is not required to exercise the same standard of care otherwise required.” (McShane v.
Cleaver, supra, 247 Cal.App.2d at p. 268, italics added.) It is true, as defendants point
out, that CACI No. 452 uses the words “plaintiff” and “defendant” in setting out the
doctrine,3 but the instruction simply uses terms applicable to the most common situation;
it does not set the boundaries for application of the doctrine. Where, as here, a third
party‟s asserted negligence is a material issue in the case, the reasonableness of that
person‟s response to a claimed emergency is also a material issue and properly
considered by the jury.

V. The evidentiary and instructional errors were prejudicial and require reversal of the
judgment.

No judgment may be reversed for “misdirection of the jury” or “improper
admission or rejection of evidence” unless the error has resulted in “a miscarriage of
justice.” (Cal. Const., art. VI, § 13.) “Article VI, section 13 of the California Constitution
requires examination of each individual case to determine whether prejudice actually
occurred in light of the entire record.” (Soule v. General Motors Corp. (1994) 8 Cal.4th
548, 580.)
The prejudice here is unmistakable. After having erroneously excluded competent
evidence tending to show that Continental knew or should have known of the potential
danger of old tires to rupture, the court granted nonsuit on plaintiff‟s strict liability cause
of action for failure to have presented that very evidence. The same excluded evidence—
numerous user manuals and trade publications—was also highly relevant to plaintiff‟s
cause of action for negligence, as was the excluded admission by Tai that he had
previously returned to the manufacturer old tires because of their danger. And the
erroneous failure to give the requested instruction on the sudden emergency doctrine

more than likely affected the jury‟s evaluation of the reasonableness of Ibarra‟s response
to the tire blowout and the extent to which the defendants‟ actions could be considered
responsible for the accident and resulting injuries. In the absence of these several errors,
there is a significant likelihood that the outcome of the trial would have been different.4
These errors prejudicially affected the verdict and thus require reversal.5

DISPOSITION

The judgment is reversed and the matter is remanded for further proceedings
consistent with this opinion. Plaintiff shall recover costs incurred on appeal upon timely
application in the trial court. (Cal. Rules of Court, rule 8.278.)

We reject Tai‟s assertion, stressed at oral argument, that the errors were harmless
because there was no evidence that the tire that burst was on the van when Tai serviced
the vehicle. In the absence of evidence that the tires on the van were changed between the
time Tai rotated the tires in July 2004 and the accident in September 2005 (much less in
the month between Tai‟s adjustment of the steering wheel and the accident), the jury was
entitled to infer that the tire on the van at the time of the accident was on the vehicle
when Tai serviced it.

Reversal of the judgment obviates the need to address plaintiff‟s claim that the court
erred in awarding costs. The award of costs to defendants as the prevailing parties falls
with the judgment.
