McLay, Mark G. Bonino and Lauren M. Case for Defendants and Respondents.

       Benjamin Perez was injured when the car he was riding in struck a tractor-trailer.

Benjamin and Celia Ramirez (together Ramirez) were parents of Oscar Ramirez (Oscar),

a passenger in the same car as Perez. Oscar was killed in the accident. In separate suits

that were eventually consolidated, Perez and Ramirez (together Appellants) sued Navman

USA, Inc., Navman Wireless North America, and Absolute Wireless, Inc. (collectively

Respondents). Respondents manufactured, supplied, warranted, or were otherwise

involved in the production and sale of a certain GPS unit that was used by the driver of

the tractor-trailer. Appellants alleged that the GPS unit provided the wrong directions to

the driver of the tractor-trailer, which ultimately caused the accident.

       Respondents filed a motion for summary judgment, which the superior court

granted against all of Appellants' claims. Appellants appeal the ensuing judgment,

contending a triable issue of material fact exists as to causation. We agree with the

superior court that no such triable issue of material fact exists. Therefore, we affirm.

                    FACTUAL AND PROCEDURAL BACKGROUND

       Frank Perez (Frank), a professional truck driver employed by KLX Inc., was

driving an empty tractor-trailer from Bakersfield to Moreno Valley to pick up cargo.

Before leaving Bakersfield, Frank entered the destination address on Globe Street into the

truck's GPS unit.

                                              2
       Frank was in the middle lane of three northbound lanes on Perris Boulevard as he

approached Globe Street. The audio directions from the GPS unit in his rig instructed

Frank to turn left onto Globe Street. Frank activated his left turn signal, but noticed on

the street sign at the right of the upcoming intersection that the correct turn was to the

right, not to the left.

       Frank then changed his turn signal to the right and began the move into the right-

hand lane on Perris Boulevard. After he made the decision to turn right, Frank no longer

consulted the GPS unit. When Perez looked to make sure the right lane was clear before

merging, he saw a passenger car (an Acura) come "outta [sic] nowhere, driving fast."

Perez saw the Acura swerving from lane to lane at a high rate of speed and was

concerned that the car might hit his tractor-trailer no matter what lane he was in.1

       Frank attempted to avoid the collision by turning his wheel back to the left so as to

remain in the middle lane on Perris Boulevard. The car hit the rear end of the trailer on

its left rear corner.2 The impact of the collision took the roof off the car and damaged its

right front end.



1      There was no evidence in the record that the tractor-trailer completely moved out
of the middle lane.

2        At oral argument, representations were made that the Acura was traveling 70 to 75
miles per hour at the time of the accident while the tractor-trailer was traveling 25 to 30
miles per hour. However, the record is clear regarding the actual speeds of the two
vehicles. According to various California Highway Patrol (CHP) witness interviews, the
speed of the Acura ranged from 50 to 75 miles per hour with the CHP's time and distance
analysis calculating the Acura's speed at 62 miles per hour. In regard to the tractor-
trailer, there is evidence that it was traveling from 5 to 45 miles per hour with the CHP's
time and distance analysis calculating the speed at 27 miles per hour.
                                              3
       Perez was severely injured in the accident, and Oscar died from his injuries. The

driver of the Acura was arrested for driving while under the influence of alcohol or drugs.

(Veh. Code, § 23152, subd. (a).)

       Ramirez and Perez filed separate complaints against Respondents. The two

actions were consolidated and Perez's complaint was designated the lead case. Both

operative complaints included causes of action for products liability. In addition, Perez

alleged a claim for negligence and Ramirez brought a wrongful death claim.

       Respondents filed a motion for summary judgment, focusing on the lack of a

triable issue of material fact as to the issue of causation. Appellants opposed the motion

for summary judgment, arguing that an issue of fact existed as to causation based on

Frank's deposition testimony; Frank's testimony in a previous, related lawsuit; the

declaration of a third party eyewitness (Jonathan Rangel, Jr.); and the declaration of

expert witness Dr. Frank Drews.

       Respondents filed a reply to the Appellants' opposition. As part of the reply,

Respondents objected to some of the evidence submitted by Appellants, including

portions of Rangel's and Drews's respective declarations.

       After hearing oral argument and considering the pleadings and evidence, the

superior court granted the motion for summary judgment. In doing so, the court

explained: "The Court finds that Defendants have met their initial burden of producing

evidence to show that causation cannot be established. The court finds that Plaintiff[s]

ha[ve] not met [their] burden to show that a triable issue of fact exists." Included in the

order, the court sustained and overruled certain of Appellants' objections to evidence as

                                              4
well as Respondents' objections to evidence. The court did not explain the basis for these

rulings.

       The court entered judgment based on its order granting summary judgment.

Appellants timely appealed.

                                       DISCUSSION

       Appellants claim the superior court committed reversible error in granting

Respondents' motion for summary judgment. They contend a triable issue of material

fact exists as to the element of causation, which is essential to the three causes of action

at issue. (See Artiglio v. Corning Inc. (1998) 18 Cal.4th 604, 614 [negligence]; Soule v.

General Motors Corp. (1994) 8 Cal.4th 548, 572 [strict products liability]; Quiroz v.

Seventh Ave. Center (2006) 140 Cal.App.4th 1256, 1263 [elements of cause of action for

wrongful death are the tort (negligence or other wrongful act), the resulting death, and the

damages, consisting of the pecuniary loss suffered by the heirs].)3

                                              I

                      THE MOTION FOR SUMMARY JUDGMENT

                                  A. Standard of Review

       "On appeal after a motion for summary judgment has been granted, we review the

record de novo, considering all the evidence set forth in the moving and opposition

papers except that to which objections have been made and sustained." (Guz v. Bechtel

National, Inc. (2000) 24 Cal.4th 317, 334 (Guz).) Generally, if all the papers submitted


3     Ramirez's wrongful death claim was based on the torts of negligence and strict
products liability.
                                              5
by the parties show there is no triable issue of material fact and the "moving party is

entitled to a judgment as a matter of law" (Code Civ. Proc.,4 § 437c, subd. (c)), the court

must grant the motion for summary judgment. (Aguilar v. Atlantic Richfield Co. (2001)

25 Cal.4th 826, 843 (Aguilar).)

       In performing our independent review, we apply the same three-step process as the

trial court. "Because summary judgment is defined by the material allegations in the

pleadings, we first look to the pleadings to identify the elements of the causes of action

for which relief is sought." (Baptist v. Robinson (2006) 143 Cal.App.4th 151, 159

(Baptist).)

       We then examine the moving party's motion, including the evidence offered in

support of the motion." (Baptist, supra, 143 Cal.App.4th at p. 159.) A defendant moving

for summary judgment has the initial burden of showing that a cause of action lacks merit

because one or more elements of the cause of action cannot be established or there is a

complete defense to that cause of action. (§ 437c, subd. (o); Aguilar, supra, 25 Cal.4th at

p. 850.)

       If the defendant fails to make this initial showing, it is unnecessary to examine the

plaintiff's opposing evidence and the motion must be denied. However, if the moving

papers make a prima facie showing that justifies a judgment in the defendant's favor, the

burden shifts to the plaintiff to make a prima facie showing of the existence of a triable

indicated.
                                             6
issue of material fact. (§ 437c, subd. (p)(2); Aguilar, supra, 25 Cal.4th at p. 850; Kahn v.

East Side Union High School Dist. (2003) 31 Cal.4th 990, 1002-1003.)

        In determining whether the parties have met their respective burdens, "the court

must 'consider all of the evidence' and 'all' of the 'inferences' reasonably drawn therefrom

[citation], and must view such evidence [citations] and such inferences [citations], in the

light most favorable to the opposing party." (Aguilar, supra, 25 Cal.4th at p. 843.)

"There is a triable issue of material fact if, and only if, the evidence would allow a

reasonable trier of fact to find the underlying fact in favor of the party opposing the

motion in accordance with the applicable standard of proof." (Id. at p. 850, fn. omitted.)

Thus, a party "cannot avoid summary judgment by asserting facts based on mere

speculation and conjecture, but instead must produce admissible evidence raising a triable

issue of fact." (LaChapelle v. Toyota Motor Credit Corp. (2002) 102 Cal.App.4th 977,

981.)

           B. Respondents Established No Triable Issue of Fact as to Causation

        Appellants only challenge the superior court's finding that no triable issue of fact

exists as to the element of causation. Here, Respondents maintain that the evidence was

insufficient to establish a "factual causal link" between the defective GPS unit, which

provided incorrect directions, and the accident between the Acura and the tractor-trailer.

Respondents provided evidence that the GPS unit instructed Frank to turn left, but he

determined that he should turn right, believing it safe to do so. Further, Respondents

assert from that moment moving forward, all decisions regarding the operation of the



                                              7
tractor-trailer and the Acura were made by the subject drivers and not influenced or

otherwise controlled by the GPS unit.

       Respondents maintain the evidence shows before Frank moved to the right, he

noticed the Acura approaching from behind, swerving between lanes. The driver of the

Acura, who was under the influence of alcohol and drugs, hit the tractor-trailer on the

back left corner of the trailer while the tractor-trailer was in the middle lane.

       Based on this evidence, we conclude that Respondents, as the moving parties,

carried their burden on the motion for summary judgment. Therefore, we move on to

examine Appellants' evidence to see if they established a triable issue of material fact. In

doing so, we look at three sources of evidence offered by Appellants: Dr. Drews's

declaration, Frank's deposition testimony, and the Rangel declaration. However, before

we evaluate this evidence, we must consider Respondents' objections to evidence.

                         C. Respondents' Objections to Evidence5

       Although a review of a judgment following the granting of a summary judgment

requires an independent review, "[a] different analysis is required for our review of the

trial court's . . . rulings on evidentiary objections. Although it is often said that an

appellate court reviews a summary judgment motion 'de novo,' the weight of authority

holds that an appellate court reviews a court's final rulings on evidentiary objections by

applying an abuse of discretion standard." (Carnes v. Superior Court (2005) 126


5      Although Appellants objected to evidence as well, the superior court's rulings on
Appellants' objections are not challenged on appeal. As such, we omit any discussion of
these objections and only consider evidence submitted by Respondents that the court
admitted for purposes of the motion for summary judgment.
                                               8
Cal.App.4th 688, 694; see Miranda v. Bomel Construction Co, Inc. (2010) 187

Cal.App.4th 1326, 1335.)6

       Here, Respondents made a total of 38 objections to evidence. The court sustained

Respondents' objections to evidence numbers 31 and 33 through 38. It overruled all of

Respondents' other objections.

       Appellants challenge the superior court's evidentiary ruling, focusing on objections

to Drews's declaration (objection nos. 33 through 36). First, Appellants claim that the

court provided no basis for the exclusion of portions of Drews's declaration, and as such,

the exclusion was arbitrary. Appellants, however, provide no authority for this

proposition. Our independent research has uncovered none. Moreover, we would not

create a rule requiring such on the record here. For each of the objections at issue,

Respondents presented the evidence objected to as well as the basis of the objection.

Appellants therefore are not left to guess on what grounds the court sustained the

objections. (Cf. Nazir v. United Airlines, Inc. (2009) 178 Cal.App.4th 243, 255

[concluding the trial court erred in issuing a blanket ruling sustaining all but one of the

defendants' 764 objections to evidence, noting "[s]ome of the sustained objections did not

even assert any basis for the objection!").]




6      Our high court, however, has not weighed in on the issue. (See Reid v. Google,
Inc. (2010) 50 Cal.4th 512, 535 ["we need not decide generally whether a trial court's
rulings on evidentiary objections based on papers alone in summary judgment
proceedings are reviewed for abuse of discretion or reviewed de novo"].) However,
under either standard, we find no error in the superior court's exclusion of portions of
Drews's declaration.
                                               9
       Second, Appellants complain that they were not afforded the opportunity to "be

heard on the evidentiary objections." Appellants' argument, however, is not supported by

the record. During the hearing on the motion for summary judgment, the court informed

counsel that it saw "a real causation problem." Perez's counsel and Ramirez's counsel

both emphasized the evidence they believed showed a triable issue of fact as to proximate

cause, focusing on Frank's reliance on the GPS unit. In response, Respondents' counsel

attacked the admissibility of Drews's declaration, making reference to Respondents'

objections to evidence while arguing the evidence did not allow Drews "in any kind of

evidentiary way . . . to connect his theory of distracted driving and the accident that

happened." In addition, Respondents' counsel also referenced the objections to Rangel's

declaration.

       The court then allowed both Ramirez's counsel and Perez's counsel to respond, but

they did not address Respondents' objections. Thus, the court provided Appellants with a

chance to discuss Respondents' objections to evidence at the hearing on the summary

judgment motion, but counsel declined to do so.

       Finally, Appellants maintain that the superior court improperly ignored Drews's

"ultimate opinion" on causation because Respondents did not object to it. This opinion

was "[g]iven the evidence summarized herein, it is my professional opinion that the

misdirection to turn left given by the [GPS unit] was a substantial contributing factor in

causing the subject accident and plaintiffs' resulting injuries." Appellants characterize

Drews's opinion as uncontroverted, and contend for purposes of opposing the motion for

summary judgment, the court had to rely upon it. We disagree, noting the court sustained

                                             10
objections to the foundational portions of Drews's declaration. In the absence of those

segments, Drews's causation opinion lacks the necessary foundation. Further, and more

importantly, we determine that the court was correct, under Evidence Code section 801,

to implicitly disregard Drews's "ultimate opinion."

                        1. The Objections to Drews's Declaration

       Drews was an expert witness for Perez who was "retained . . . to investigate and

advise on the causative factors involved in the . . . [subject] accident." Drews's

declaration was submitted in support of Perez's opposition to the motion to summary

judgment. In response to that declaration, Respondents' objected to a portion of

paragraph 8 of the declaration, all of paragraphs 9 and 10, and a portion of paragraph 11.

       In paragraph 8, Drews declared: "Based upon the foregoing facts and materials

and upon my training and experience in the field of human factors and safety in the use of

data displays and equipment and in the field of driver distraction, I can render the

following professional opinions. Frank Perez relied on the navigation instructions given

by the [GPS unit], turned on his left-turn signal, and started to move to the left to make a

left-hand turn, whereupon he was distracted by (a) seeing the Acura vehicle approaching

from behind, and (b) at the same time, he became confused by the contradictory

information provided by the [GPS unit] and the street signs." (Italics added.)

Respondents objected to Drews's use of the phrase "at the same time" in the last sentence

on the grounds that it misstates the evidence and was contrary to an earlier portion of

Drews's declaration. The court sustained this objection.



                                             11
       In paragraph 9 of his declaration, Drews stated: "A professional truck driver who

has relied on the [GPS unit's] directions without incident for approximately 1,000 trips,

will have followed literally tens of thousands of turn-by-turn instructions from the system

without being misdirected, and can reasonably be expected to come to rely on the device

to reliably direct him to his destination. Given the evidence summarized herein and

based on my experience in the field of human factors psychology and safety in the use of

data displays and equipment and in the field of driver distraction, a driver under such

conditions can reasonably be expected to develop a complacency to automation, i.e., the

driver relies blindly on the system. This reliance makes a driver ill-prepared to respond

to incorrect instructions. Although a system which provides auditory cues as well as

visual cues will somewhat relieve a driver from excessive 'heads down' time engrossed in

the device, nevertheless, due to the complacency to automation associated with repeated

successful use of the system, a driver given misdirections or contradictory instructions

will not be able to maintain sufficient situation awareness with regard to surrounding

traffic to correctly predict other vehicles [sic] actions and to correctly position his vehicle

to avoid a collision." Respondents objected to this entire paragraph on the grounds of

lack of foundation and speculation to the extent that the paragraph was attempting to

explain Frank's actions in driving the tractor-trailer or how he would act in a particular

circumstance. The court sustained this objection.

       In paragraph 10 of his declaration, Drews declared: "A driver who encounters the

conditions shown by the evidence summarized herein is required to multi-task and

respond quickly to solve the navigation problem and make a decision on how to proceed.

                                              12
Given the high level of cognitive processing demanded by this situation, it is to be

expected that a driver in these conditions will decide to change directions from the left-

turn direction given by the navigational system, turn to the right in response to the street

sign directing the driver to the right, and then take avoidance maneuvers in response to

the threats he has created from traffic approaching from behind." Respondents objected

to this entire paragraph on the grounds of lack of foundation and speculation to the extent

that the paragraph was attempting to explain Frank's actions in driving the tractor-trailer

or how he would act in a particular circumstance. The court sustained this objection.

       In paragraph 11, Drews stated: "Given the evidence summarized herein, it is my

professional opinion that the misdirection to turn left given by the [GPS unit] was a

substantial contributing factor in causing the subject accident and the plaintiffs' resulting

injuries. Just prior to the subject accident, Frank Perez prepared to make a left turn

consistent with the auditory and visual navigation cues provided the [GPS unit], which he

discovered were incorrect upon seeing the conflicting street signs. The evidence shows

that as a direct result of the misdirection supplied by the [GPS unit], [Frank] was

confused by the conflicting information from the street signs, and acted in a reasonably

foreseeable manner in seeking to correct the mistaken directions by moving to the right,

whereupon he was confronted with yet another foreseeable hazard, a speeding driver

coming upon [Frank's] tractor-trailer rig from behind, whereupon he moved back to the

left, resulting in the collision." (Italics added.) Respondents objected to the phrase

"acted in a reasonably foreseeable manner" on the grounds of lack of foundation for a

legal conclusion. The court sustained the objection.

                                             13
       As a threshold matter, we note that Appellants only argue that the superior court

abused its discretion in excluding portions of Drews's declaration when it failed to

provide: (1) any reasoning in support of its sustaining the objections or (2) Appellants

the opportunity to address the objections. As we discuss above, we find no merit in either

of these conditions. Moreover, these contentions do not challenge the substance of the

objections, but instead, deal with the procedure the superior court used in ruling on the

objections. Appellants thus have not articulated any other reason why the superior court's

ruling on the objections was incorrect. Thus, they have waived any issue concerning the

correctness of these specific evidentiary rulings. (Villa v. McFerren (1995) 35

Cal.App.4th 744, 739, fn. 4.) We therefore consider all such evidence to have been

properly excluded. (See Mansell v. Board of Administration (1994) 30 Cal.App.4th 539,

545-546 [not the proper function of Court of Appeal to search the record on behalf of

appellants or to serve as "backup appellate counsel"].)

                             2. Drews's Opinion on Causation

       Appellants maintain even if we conclude that the superior court did not abuse its

discretion in sustaining the objections to portions of Drews's declaration, enough of

Drews's declaration was admitted into evidence to create a triable issue of fact.

Appellants insist that the majority of Drews's opinion about causation from paragraph 11

was admitted into evidence and was uncontroverted. Therefore, Appellants assert a

triable issue of fact exists. We disagree.

       At the outset, we note Appellants do not address the impact of the superior court's

exclusion of paragraphs 9 and 10 of Drews's declaration on Drews's opinion contained in

                                             14
paragraph 11. The exclusion of those two paragraphs eviscerated most of the substance

of Drews's opinion in paragraph 11, which relied on the conclusions reached in the two

excluded paragraphs. For this reason alone, we find no error. However, even if we

analyze the substance of Drews's causation opinion without reference to paragraphs 9 and

10, we would conclude that the court did not abuse its discretion in disregarding it.7

       Evidence Code section 801 provides: "If a witness is testifying as an expert, his

testimony in the form of an opinion is limited to such an opinion as is: [¶] (a) Related to

a subject that is sufficiently beyond common experience that the opinion of an expert

would assist the trier of fact; and [¶] (b) Based on matter . . . that is of a type that

reasonably may be relied upon by an expert in forming an opinion upon the subject to

which his testimony relates, unless an expert is precluded by law from using such matter

as a basis for his opinion." "Subdivision (b) clearly permits a court to determine whether

the matter is of a type on which an expert may reasonably rely." (Sargon Enterprises,

Inc. v. University of Southern California (2012) 55 Cal.4th 747, 770 (Sargon).) "[T]he

matter relied on must provide a reasonable basis for the particular opinion offered, and

that an expert opinion based on speculation or conjecture is inadmissible." (Lockheed

Litigation Cases (2004) 115 Cal.App.4th 558, 564; see Sargon, supra, at p. 770.)

       Evidence Code section 801 is not the only statute that governs a superior court's

consideration of expert witness testimony. It must also consider Evidence Code section

802. (Sargon, supra, 55 Cal.4th at p. 771.) Evidence Code section 802 provides: "A


7     We would reach the same result if we independently reviewed Drews's causation
opinion.
                                               15
witness testifying in the form of an opinion may state . . . the reasons for his opinion and

the matter . . . upon which it is based, unless he is precluded by law from using such

reasons or matter as a basis for his opinion. The court in its discretion may require that a

witness before testifying in the form of an opinion be first examined concerning the

matter upon which his opinion is based." "This section indicates the court may inquire

into the expert's reasons for an opinion. It expressly permits the court to examine experts

concerning the matter on which they base their opinion before admitting their testimony.

The reasons for the experts' opinions are part of the matter on which they are based just

as is the type of matter. Evidence Code section 801 governs judicial review of the type of

matter; Evidence Code section 802 governs judicial review of the reasons for the

opinion." (Sargon, supra, at p. 771, italics omitted.)

       "Thus, under Evidence Code sections 801, subdivision (b), and 802, the trial court

acts as a gatekeeper to exclude expert opinion testimony that is (1) based on matter of a

type on which an expert may not reasonably rely, (2) based on reasons unsupported by

the material on which the expert relies, or (3) speculative. Other provisions of law,

including decisional law, may also provide reasons for excluding expert opinion

testimony." (Sargon, supra, 55 Cal.4th at pp. 771-772.)

       "The trial court's preliminary determination whether the expert opinion is founded

on sound logic is not a decision on its persuasiveness. The court must not weigh an

opinion's probative value or substitute its own opinion for the expert's opinion. Rather,

the court must simply determine whether the matter relied on can provide a reasonable



                                             16
basis for the opinion or whether that opinion is based on a leap of logic or conjecture."

(Sargon, supra, 55 Cal.4th at p. 772.)

       Against this backdrop, we conclude the trial court did not err in implicitly

rejecting Drews's opinion on causation. Drews opines "as a direct result of the

misdirection supplied by the [GPS unit], [Frank] was confused by the conflicting

information from the street sign, and acted in a reasonably foreseeable manner in seeking

to correct the mistaken directions by moving to the right." Drews reached this opinion by

asserting, as a general principle, that a driver who frequently has used a navigational

device can come to rely on the navigational device and can "reasonably be expected to

develop a complacency to automation."

       Drews maintained that the complacency results in a driver who, when confronted

with incorrect or contradictory instructions, is unable to maintain situational awareness

relative to predicting what other vehicles might do or positioning his own vehicle to

avoid a collision. Drews further concludes without stating a basis that "it is to be

expected that a driver in these conditions will decide to change directions from the left-

turn direction given by the navigational system, turn to the right in response to the street

sign directing the driver to the right, and then take avoidance maneuvers in response to

the threats he has created from traffic approaching from behind."

       Drews's opinion is based on layers of speculation. He assumes Frank developed a

"complacency to automation." There is no evidence in the record to support his

conclusion. Drews presumes that Frank was incapable of maintaining situational

awareness. Again, no evidence supports this presumption. To the contrary, it appears

                                             17
that Frank maintained situational awareness by using his indicators, noticing the speeding

and swerving Acura approaching from behind, and mostly staying in the number 2 lane.

In addition, Drews's opinion appears to rest on the belief that Frank was confused while

he was changing lanes. Appellants, however, do not cite to any evidence that established

that Frank ever caused his tractor-trailer to change lanes out of the number 2 lane and that

he was confused when he did so. Our independent review of the record leads us to

determine that the evidence was ambiguous at best. Frank denied that he ever got into

the number 1 lane. Frank also testified that he did not recall if he ever moved into the

number 3 lane. In addition, Frank testified that he decided not to move lanes, but to stay

in the number 2 lane to avoid being hit by the Acura, which he saw swerving back and

forth from the number 1 to the number 3 lane.

       Drews's opinion is speculative and conclusory. He had no evidence that Frank had

grown complacent by his overuse of the GPS device, or that he would blindly rely on the

GPS device, or that somehow Frank's complacency or blind reliance led him to be unable

to perceive the situation (i.e., he became confused) and react appropriately. Drews's

opinion does nothing more than opine that " 'something could be true if certain assumed

facts are true,' " and is therefore devoid of foundation. (See Dee v. PCS Property

Management, Inc. (2009) 174 Cal.App.4th 390, 404.)

       In short, in providing his opinion on causation, Drews speculated both as to what a

driver like Frank would have done, and to how Frank himself would have reacted to the

situation. The opinion offered by Drews is not reasonably based on Frank's deposition



                                            18
testimony or any other evidence in the record.8 As such, the superior court was correct to

disregard it. (See Wise v. DLA Piper LLP (2013) 220 Cal.App.4th 1180, 1188

["speculation is not evidence, less still substantial evidence."].)

                                    D. Proximate Cause

       Even if Drews's opinion is disregarded, Appellants claim the court erred in

granting summary judgment because a triable issue of fact exists as to proximate cause.

Appellants point us to two other sources of evidence on proximate cause: Frank's

deposition testimony and Rangel's declaration. We independently reviewed this evidence

and conclude that no triable issue of fact exists as to proximate cause.

       Proximate cause involves two elements: (1) cause in fact, and (2) the extent to

which public policy considerations limit a defendant's liability for its acts. (PPG

Industries, Inc. v. Transamerica Ins. Co. (1999) 20 Cal.4th 310, 315-316.) Cause in fact

asks whether the defendant's conduct was the " 'necessary antecedent' " to the injury,

without which no injury would have occurred. (Maupin v. Widling (1987) 192

Cal.App.3d 568, 573.) In other words, the actor's conduct must be a " 'substantial



8       Drews stated that he read and relied on the Rangel declaration. In that declaration,
Rangel claimed to have seen Frank's tractor-trailer swerving and moving lane to lane:
"The tractor-trailer combination swerved from right to left, then back to the right, then
back to the left again." Even accepting Rangel's declaration as true, there still exists a
substantial gap in Drews's opinion for explaining Frank's supposed erratic driving. In
other words, even relying on Rangel's declaration, Drews's opinion still speculates as to
the cause of Frank changing lanes, and thus, the opinion was properly excluded. (See
Sargon, supra, 55 Cal.4th at p. 776.) Moreover, Drews's opinion describes the movement
of the tractor-trailer inconsistently with the description of the tractor-trailer's movement
in the Rangel declaration. Thus, it does not appear that Drews relied on Rangel's account
of Frank's driving of the tractor-trailer.
                                              19
factor' " in bringing about the harm. (See Nola M. v. University of Southern California

(1993) 16 Cal.App.4th 421, 427.) A substantial factor, for purposes of causation, is

something that is more than " 'a slight, trivial, negligible, or theoretical factor in

producing a particular result.' " (Espinosa v. Little Co. of Mary Hospital (1995) 31

Cal.App.4th 1304, 1314.) The second element of proximate cause is " ' "concerned, not

with the fact of causation, but with the various considerations of policy that limit an

actor's responsibility for the consequences of his conduct." ' " (Ferguson v. Lieff,

Cabraser, Heimann & Bernstein (2003) 30 Cal.4th 1037, 1045.)

       "[T]he question of proximate cause . . . becomes one of law where the facts are

uncontroverted and only one deduction or inference may reasonably be drawn

therefrom." (Whinery v. Southern Pac. Co. (1970) 6 Cal.App.3d 126, 128.) " 'A mere

possibility of . . . causation is not enough; and when the matter remains one of pure

speculation or conjecture, or the probabilities are at best evenly balanced, it becomes the

duty of the court to direct a verdict for the defendant.' [Citation.]" (Saelzler v. Advanced

Group 400 (2001) 25 Cal.4th 763, 775-776; italics omitted.)

       According to Appellants, Frank's deposition testimony established, based on

erroneous directions provided by the GPS unit, Frank "moved over" to turn left, realized

he needed to turn right when he saw the street signs, became confused, decided to turn

right, began to merge right into the number 3 lane when he noticed the Acura "come from

behind his truck at a high rate of speed," and Frank tried to avoid a collision with the

Acura by turning the steering wheel to the left. Put differently, Appellants maintain that

Frank testified to a series of lane changes initiated by the wrong directions provided by

                                               20
the GPS unit, which caused the Acura to hit the back of the tractor-trailer. However,

Frank's testimony does not establish that the GPS unit's wrong directions were a

substantial factor in causing the accident. There is no support for Appellants' claim that

Frank was confused when he decided to turn right, put on his right indicator, and then

prepared to merge into the right lane when he saw the Acura. Frank does admit that he

was "somewhat confused" when he saw the street signs conflicted with the directions

provided by the GPS unit. Nevertheless, after realizing that he needed to turn right, there

is no evidence that Frank remained confused, acted erratically, or otherwise drove

dangerously. In fact, the evidence suggests that Frank drove cautiously and carefully

when he determined he needed to turn right. He put on his right indicator, checked his

mirrors, and was traveling at about 25 to 30 miles per hour. Moreover, he admits that he

was not relying on the GPS unit at that time.

         In addition, Appellants' position relies on their claim that Frank was moving in and

out of lanes. Yet, Frank's testimony on this point is much more ambiguous than

Appellants admit. For example, during Frank's deposition, the following exchange took

place:

            "Q: Mr. Greenberg confirmed for me that you related the story,
            which is very similar to what appears to have been related by you to
            the police officer investigating the case, that immediately prior to the
            collision you were relying on the [GPS unit] to direct you where to
            make a left-hand turn; is that correct?

            "A: Correct.

            "Q: And that in reliance on that device you were following its
            instructions and had moved over believing that you could make a
            left-hand turn; is that correct?

                                              21
          "A: Correct.

          "Q: And then at some point you realized that the device was giving
          you the wrong information; it was not giving you an accurate
          position and giving you accurate information in terms of what you
          could do and you then elected to make a right-hand turn; correct?

          A: Correct.

Although Frank agrees that he "moved over" there is no context provided in the portion

of the deposition in the record establishing that Frank meant that he changed lanes into

the number 1 lane. In the portion of that deposition testimony provided to the court, there

is no indication that it was established what lane Frank was in, where and when he moved

the tractor-trailer from one lane to another (if at all), or if Frank moved back from the

number 1 lane into the number 2 lane if Frank actually moved into the number 1 lane at

some point. As such, this deposition testimony requires the court to speculate to find that

it establishes Frank was moving lane to lane because of the improper directions provided

by the GPS unit. Thus, without more, Frank's agreement that he "moved over" does not

establish or even call into question whether he moved into the number 1 lane or moved

back to the number 2 lane and ultimately caused the accident based on the GPS unit's

wrong directions. The deposition does not contain the necessary foundation to establish

what was meant by the term "moved over" or what occurred following this apparent

move. Also, during his deposition, Frank denied that he ever changed lanes into the

number 1 lane. Indeed, the question of whether Frank moved the tractor-trailer into the

number 1 lane was asked multiple times during the deposition and Frank answered

consistently each time that he did not move the tractor-trailer into the number 1 lane.


                                             22
       The same is true regarding Frank moving into the number 3 lane. At best, the

testimony suggests that Frank was beginning to merge into the number 3 lane, when he

saw the Acura swerving from lane to lane, traveling at great speed, coming up behind the

tractor-trailer.9 At that point, Frank elected to stay in the number 2 lane and the Acura

hit the back left portion of the trailer.

       The evidence in the record shows that Frank believed he was supposed to turn left

because of the directions provided by the GPS unit. He was traveling in the number 2

lane. He turned on his left indicator and prepared to move to the left into the number l

lane. However, he surmised from the street signs that he really needed to turn right. So

he did not move into the number 1 lane, but instead, put on his right indicator and

prepared to merge into the number 3 lane on the right. At that time, he saw the Acura

come from behind at a great rate of speed and swerving from lane to lane. To avoid a

potential collision, Frank turned the steering wheel left to stay in the number 2 lane and

the Acura collided with the back left corner of the trailer. Although the GPS unit's

directions caused Frank to believe he needed to turn left, and, in reliance on the directions

provided by the GPS unit, put on the left indicator, it would be pure conjecture to

conclude the wrong directions were a causal factor in the accident that followed after

Frank decided to turn right and put on his right indicator. This is especially true here

where the evidence shows the Acura was speeding from behind the tractor-trailer,


9      Frank provided conflicting testimony about when he first sees the Acura. He
originally testified that he saw the Acura as he was preparing to turn left. Later in his
deposition, after having his recollection refreshed, Frank agreed that he did not see the
Acura until he was preparing to turn right.
                                             23
swerving from lane to lane, with an intoxicated driver behind the wheel. Moreover, there

is nothing in Frank's testimony that would allow the trier of fact to determine that he was

confused, unaware of his situation, or otherwise hindered in his driving ability by the

wrong directions provided by the GPS unit. To the contrary, the evidence shows that he

acted reasonably, safely, and carefully, by putting on his right indicator and checking his

mirrors before merging. When he saw the Acura speeding up from behind, changing

lanes, he decided to stay in his current lane. The Acura then hit the left back corner of

the trailer. Based on this evidence, the wrong directions provided by the GPS unit are

nothing more than a slight, trivial, or negligible factor in producing the accident. (See

Espinosa v. Little Co. of Mary Hospital, supra, 31 Cal.App.4th at p. 1314.)

       In addition, Rangel's declaration does not support Appellants' position here.

Rangel stated that he observed the tractor-trailer swerving from lane to lane and move in

front of the Acura, causing the Acura to hit it. Nevertheless, Rangel's declaration does

not establish why the tractor-trailer was swerving. In other words, it does not establish

that the wrong directions provided by the GPS unit caused Frank to swerve both left and

right and ultimately in front of the Acura. As such, Rangel's declaration, even when

considered with Frank's deposition testimony, does not create a triable issue of fact as to

whether the GPS unit's wrong directions were a substantial factor of the accident.

       Because we conclude this is the rare case where only one inference may be drawn

from the undisputed facts (see Whinery v. Southern Pac. Co., supra, 6 Cal.App.3d at

p. 128), we do not evaluate the public policy element of proximate cause. That said, we

struggle to contemplate any public policy that would support finding liability as to

Respondents on the facts in the record before us. The wrong directions provided by the

GPS unit were simply too remote to be anything more than a trivial factor in the

unfortunate accident.
