    Defendant and Respondent.
    THE COURT:
    IT IS ORDERED that the opinion filed herein on May 15, 2013, be
    modified as follows:
    1. On page 2, last line of first full paragraph, add the words "on liability
    and damages" to the end of the sentence.
    2. On page 3, last line (sentence carries over to page 4), replace "At the
    close of plaintiffs' case, Bert’s asked" to read: "After the Pedeferri plaintiffs rested,
    Bert’s moved . . . ."
    3. On page 4, carry-over paragraph from page 3, substitute for the last
    sentence the following: "The court and the parties treated the motion as timely, and the
    court denied the request."
    4. On page 5, second full paragraph, first sentence, replace "White settled
    with all plaintiffs" to read: "White settled with the Pedeferri plaintiffs . . . ."
    5. On page 5, second full paragraph, substitute for the last sentence the
    following: "White has submitted a brief aligned with the Pedeferri plaintiffs in resisting
    Bert's request for a new trial."
    6. On page 13, first full paragraph, fifth line, add "(Raven H.)" after
    "1025."
    7. On page 16, second full paragraph, add footnote (which will be footnote
    2) after the first sentence, which will read:
    For the first time in their petition for rehearing, the Pedeferri plaintiffs
    argue that Bert's forfeited this issue by not moving to strike this testimony
    until they had rested their case. We disagree. The trial court allowed the
    toxicologist to offer his opinion based on assumptions to be proven up by
    other evidence. (Evid. Code, § 403, subd. (b), (c).) In these circumstances,
    Bert’s motion to strike was "timely made" (id., § 353, subd. (a)), because it
    was made as soon as Bert's knew the Pedeferri plaintiffs had not established
    a factual foundation for the toxicologist's assumptions—that is, when the
    Pedeferri plaintiffs rested their case-in-chief. The Pedeferris plaintiffs
    contend that motions to strike made after a party rests cannot be timely
    because, if granted, they deprive the party of the ability to cure the
    evidentiary deficiency. However, this argument overlooks a court's power
    (and, in some instances, duty) to reopen a party's case. (In re Marriage of
    Olson (1980) 
    27 Cal. 3d 414
    , 422; Austin B. v. Escondido Union School
    Dist. (2007) 
    149 Cal. App. 4th 860
    , 886 [plaintiffs have a right to reopen to
    respond to nonsuit motion].)
    8. On page 17, delete the second full paragraph (beginning "This error was
    prejudicial") and replace with the following:
    There is a "reasonable probability" that the admission of the
    toxicologist’s unsupported opinion that White was a "chronic" marijuana
    user affected the jury's apportionment of liability between Bert's and White.
    (People v. Watson (1956) 
    46 Cal. 2d 818
    , 836.) The degree to which
    2
    White’s marijuana binge contributed to the accident was hotly contested at
    trial. The toxicologist’s opinion prejudiced Bert's because the plaintiffs
    used it to prove White was unimpaired, thereby reducing White's respective
    share of responsibility for the accident and increasing Bert's.
    9. On page 18, first line in carry-over paragraph from page 17, add "the
    jury was instructed" before "that his opinion."
    10. On page 18, add the following sentence at the end of the carry-over
    paragraph from page 17: "The jury's power to disregard answers to hypothetical
    questions unsupported by the facts did not obviously apply to the totality of the
    toxicologist's opinion, and did not cure its prejudicial effect."
    11. On page 18, delete last paragraph (which carries over to page 19),
    beginning with "We therefore," and replace with the following:
    We conclude that the erroneous admission of the toxicologist's
    opinion necessitates retrial of the entire liability portion of the trial. The
    Pedeferri plaintiffs argue that we need only remand on the issue of
    apportionment of liability because the toxicologist's opinion does not affect
    either our conclusion that Bert's owed a duty or the jury's finding that Bert's
    breached that duty. Although the toxicologist's opinion does not affect the
    issue of duty, there is nevertheless a "reasonable probability" that the jury's
    findings of breach and of causation were affected by that opinion. White
    provided the only eyewitness account of how the bikes were negligently
    secured while the truck was moving, and the toxicologist's opinion that
    White was unimpaired (and thus able to accurately perceive what was
    happening) ostensibly lent credence to White's account. Without the
    opinion minimizing White's culpability and inflating Bert's, the jury might
    have concluded that Bert's contribution to the accident was so "remote or
    trivial" as not to be a "substantial factor in causing harm." (Raven H.,
    supra, 157 Cal.App.4th at p. 1025.) The Pedeferri plaintiffs note our
    conclusion that White's negligence was not a superseding cause as a matter
    3
    of law, but this conclusion also does not preclude a jury from finding as a
    factual matter that Bert's negligence was not a “substantial factor” in
    causing the accident.
    We conclude that a retrial is appropriate on the issue of damages as
    well. We are mindful of the burden that retrying damages entails, as the
    damages trial was bifurcated and focused on different evidence than the
    liability trial. However, the same jury that found Bert's liable based in part
    upon the toxicologist's opinion also fixed damages, and the trial court in
    remitting the damages award found that this damages verdict was already
    tainted by an emotional response to the evidence presented. We
    accordingly conclude that retrial on liability alone would "deny [Bert's] a
    fair trial." (Bullock v. Philip Morris USA, Inc. (2008) 
    159 Cal. App. 4th 655
    ,
    696.)
    12. On page 19, first sentence under DISPOSITION, add the words "on all
    issues" to the end of the sentence.
    There is no change in the judgment.
    Plaintiff and Respondent Pedeferris' petition for rehearing is denied.

    Does a commercial vendor owe a duty of care to persons on or near the
    roadway who are injured as a result of the vendor's negligence in loading and securing
    cargo in a vehicle in a way that distracts the vehicle's driver? Applying the controlling
    principles of California law, we conclude that such a duty exists and that a categorical
    "no duty" exception for vendors should not be created. We also hold that the driver's
    negligence in driving under the influence of marijuana does not constitute a superseding
    cause as a matter of law; instead, the issue of superseding cause is one for the jury. We
    nevertheless determine that the trial court abused its discretion in not striking, for lack of
    foundation, expert testimony that the driver in this case was a "chronic" marijuana user
    and thus unlikely to be impaired. Because the driver's impairment was crucial to the
    allocation of fault between the driver and vendor, we vacate the judgment and remand for
    a new trial.
    FACTS AND PROCEDURAL HISTORY
    I. The Accident
    This case arises from a tragic accident that partially paralyzed plaintiff
    Anthony Pedeferri, a California Highway Patrol (CHP) officer, and took the life of
    Andres Parra (Parra), the young man on the side of the highway with him.
    On December 19, 2007, defendant Jeremy White (White) careened off the
    northbound 101 Freeway and slammed into an Xterra parked on the right shoulder. The
    Xterra exploded in a fireball, killing its sole occupant, Parra. The impact threw Officer
    Pedeferri 78 feet from where he was standing, and paralyzed him from the armpits down.
    At the time of the accident, White had "quite high" levels of marijuana in
    his blood. In the 24 hours leading up to the accident, White consumed half a marijuana
    cake, smoked three "bowls" of marijuana, ate a "pretty big marijuana cookie," and drank
    an eight-ounce marijuana tea. He was transporting two pounds of marijuana in his truck's
    toolbox.
    Just 90 minutes before the accident, White left Bert's Mega Mall, a
    motorsports dealership operated by defendants Seidner Enterprises LLC and RJS
    Financial (collectively, Bert's). Bert's employees had loaded and strapped down two dirt
    2
    bikes in the bed of White's truck—a new dirt bike White just purchased and a bike
    already owned by White's friend and passenger Brian Kinsler (Kinsler).
    As White drove at 74 miles-per-hour on a bumpy portion of the northbound
    101 Freeway, just north of Ventura, he felt and saw the bikes "hopping around a little bit
    in the bed of the truck." The bikes moved from side to side, as well as back and forth.
    White then heard a popping sound. He asked Kinsler to look behind him at the truck's
    bed. Then, without braking, White took his eyes off the road to glance back over his left
    shoulder, and then his right. As he did, White steered his truck slightly to the right, and
    into Parra's Xterra on the side of the freeway.
    White subsequently pled guilty to vehicular manslaughter while
    intoxicated. He was sentenced to 15 years in state prison.
    II. The Litigation
    A. The complaint and trial
    Officer Pedeferri, his wife, and Parra's mother and father (collectively,
    plaintiffs) sued White for negligence and wrongful death. They later added Bert's as a
    defendant.
    The case proceeded to a bifurcated jury trial. During the liability phase,
    plaintiffs' accident reconstruction expert testified that Bert's employees contributed to the
    accident by negligently loading and securing the bikes in the back of White's truck.
    Bert's expert offered a contrary opinion.
    Plaintiffs also called two witnesses who addressed the contribution of
    White's marijuana use to the accident. A human factors expert testified that White's
    reaction to the movement of the dirt bikes and the popping sound was reasonable, and no
    different than a sober person's. A toxicologist also testified that White was "most likely"
    not impaired by his marijuana use because White was a "chronic user." The toxicologist
    defined a "chronic user" as a person who has used marijuana for "a long period of time"
    and who has "driven before with marijuana" in his system "over and over and over." The
    toxicologist assumed White had used marijuana for a while and that White had
    previously driven while under the influence of marijuana. At the close of plaintiffs' case,
    3
    Bert's asked the trial court to strike the toxicologist's testimony on the ground that
    plaintiffs had failed to adduce any evidence to support their expert's assumptions. The
    court denied the request.
    Bert's was also not permitted to question the expert about the other drugs in
    White's bloodstream at the time of the accident—namely, Paxil, Soma, Vicodin, Ecstasy
    and cocaine. The trial court had previously ruled that this evidence had marginal
    probative value and should be excluded under Evidence Code section 352 because Bert's
    elected not to call a toxicologist to establish that the levels of those drugs in White's
    blood were sufficient to potentially impair his driving.
    The jury unanimously found White to be negligent and, by a nine-to-three
    vote, also found Bert's to be negligent. The jury unanimously assigned 67 percent of the
    fault to White, and the remaining 33 percent to Bert's. Following a separate trial on
    damages, the jury awarded a total of $49.6 million to plaintiffs.
    B. Post-trial motions
    Bert's moved for judgment notwithstanding the verdict (JNOV) in part on
    the ground that Bert's sole duty was to load and secure cargo so it would not fall out—not
    to load and secure cargo so it would not distract a driver. The trial court found Bert's
    articulation of its duty too narrow. The court ruled that "there's a duty on a commercial
    vendor that loads the goods in the back of [a] truck to use care so that those on or near the
    roadways are not harmed."
    Bert's also sought a new trial on two grounds pertinent to this appeal.1
    First, Bert's argued that the toxicologist's assumptions were never established. The trial
    court ruled that the factual basis for the expert's assumption that White had engaged in
    long-term marijuana use was "thin," but sufficient. The court did not expressly decide
    whether there was a factual basis for the expert's further assumption that White had
    previously driven while using marijuana.
    1
    Bert's sought a new trial for jury misconduct as well. In light of our
    disposition, we need not reach Bert's challenges to the trial court's denial of a new trial on
    that basis.
    4
    Second, Bert's contended that the damages were excessive. The court
    found the jury's $49.6 million award to be excessive and likely the product of "sympathy
    for the plaintiffs and outrage at the conduct of defendant White," and granted a new trial
    on damages. Plaintiffs accepted remittiturs, and the court entered judgment against
    White for $14.84 million; against Bert's for $7.3 million; and against both defendants
    jointly and severally for $13.01 million.
    White settled with all plaintiffs, and Bert's settled with the Parra plaintiffs.
    Thus, the sole remaining parties are the Pedeferri plaintiffs and Bert's. White has
    nevertheless submitted a brief aligned with the plaintiffs.
    DISCUSSION
    I. Bert's Owed Plaintiffs a Duty to Carefully Load
    and Secure Cargo in a Way that Will Not Distract the Driver
    It is not enough that Bert's may have been negligent in loading and securing
    the dirt bikes in the back of White's truck. "'Proof of negligence in the air, so to speak,
    will not do.' [Citations.]" (Palsgraf v. Long Island R.R. Co. (1928) 
    248 N.Y. 339
    , 341.)
    To be liable to a particular plaintiff, Bert's must owe that plaintiff a duty to act carefully.
    (Id., at p. 342.) Whether a duty is owed is ultimately a question of policy. (Ballard v.
    Uribe (1986) 
    41 Cal. 3d 564
    , 573, fn. 6. (Ballard)) As such, "[d]uty is a question of law
    for the court, to be reviewed de novo on appeal. [Citations.]" (Cabral v. Ralph's
    Grocery Co. (2011) 
    51 Cal. 4th 764
    , 770 (Cabral).)
    Our first step is to articulate the duty at issue. Because Bert's concedes
    that vendors owe a duty to load and secure cargo so it will not fall out of a vehicle,
    Bert's contends that the only duty at issue in this case is a vendor's duty to load and
    secure cargo so it will not distract the driver with noise or movement where that cargo
    remains in the vehicle. This is too fine a hair to split. A driver can be distracted by
    negligently loaded or secured cargo when it remains in the vehicle as well as when it falls
    out. Consequently, we will frame the issue as whether a commercial vendor owes a duty
    of care to persons on or near the roadways who are injured as a result of the vendor's
    5
    negligence in loading and securing cargo in a vehicle in a way that distracts the vehicle's
    driver irrespective of whether the cargo remains in the vehicle.
    We start with the basic tenet of California law that "everyone is required to
    use ordinary care to prevent causing injury to others. [Citations.]" (Bloomberg v.
    Interinsurance Exchange (1984) 
    162 Cal. App. 3d 571
    , 575 (Bloomberg); Merrill v.
    Navegar, Inc. (2001) 
    26 Cal. 4th 465
    , 477.) This principle is codified in Civil Code
    section 1714, subdivision (a) ["Everyone is responsible . . . for an injury occasioned to
    another by his or her want of ordinary care or skill"].) Bert's offers one reason why it
    should be excused from this general duty and two reasons why it must be excused. We
    consider and reject each.
    A. Policy-based categorical exemption from liability
    Bert's argues that policy considerations "justify a categorical 'no-duty' rule"
    that would absolve vendors of any duty to load and secure cargo in a vehicle so as not to
    distract the vehicle's driver. We certainly possess the authority to exempt entire
    categories of negligent conduct from Civil Code section 1714's duty of care when such an
    exemption is "clearly supported" by public policy. (Cabral, supra, 51 Cal.4th at p. 771;
    Ballard, supra, 41 Cal.3d at p. 573, fn. 6.) Before exercising this authority, however, we
    must ascertain whether the harm flowing from the potentially exempted conduct is
    foreseeable, and if so, whether other public policy interests nevertheless counsel against
    imposing a duty. (Cabral, supra, at pp. 774, 781; Bryant v. Glastetter (1995) 
    32 Cal. App. 4th 770
    , 778 (Bryant).)
    1. Forseeability
    Foreseeability is the "'. . . chief factor in [the] duty analysis.' [Citation.]"
    (Laabs v. So. Cal. Edison Co. (2009) 
    175 Cal. App. 4th 1260
    , 1272 (Laabs).) For these
    purposes, our task is "not to decide whether a particular plaintiff's injury was reasonably
    foreseeable in light of a particular defendant's conduct . . . ." (Ballard, supra, 41 Cal.3d
    at p. 573, fn. 6.) Instead, we must "evaluate more generally whether the category of
    negligent conduct at issue is sufficiently likely to result in the kind of harm experienced
    that liability may appropriately be imposed on the negligent party." (Ibid.; Bigbee v.
    6
    Pacific Tel. & Tel. Co. (1983) 
    34 Cal. 3d 49
    , 57 (Bigbee).) The inquiry into foreseeability
    entails three considerations: "'[1] the [general] foreseeability of harm to the plaintiff,
    [2] the degree of certainty that the plaintiff suffered injury, [and] [3] the closeness of the
    connection between the defendant's conduct and the injury suffered. . . .' [Citation.]"
    (Cabral, supra, 51 Cal.4th at p. 775, quoting Rowland v. Christian (1968) 
    69 Cal. 2d 108
    ,
    112-113 (Rowland), superseded on other grounds as stated in Calvillo-Silva v. Home
    Grocery (1998) 
    19 Cal. 4th 714
    , 722.)
    Applying this analytical framework, we can generally foresee that a
    vendor's negligence in loading or securing cargo could harm others on the roadway. It is
    foreseeable that cargo negligently loaded or secured in a vehicle could distract the
    vehicle's driver in a variety of ways—by making noise, blocking the driver's view,
    interfering with his or her control of the vehicle, or falling out. It is further foreseeable
    that a driver so distracted could injure others on or near the roadway. (Cabral, supra, 51
    Cal.4th at p. 781 [noting "general foreseeability of a collision between a vehicle leaving
    the freeway and one stopped alongside the road"]; e.g., Arthur v. Santa Monica Dairy Co.
    (1960) 
    183 Cal. App. 2d 483
     (Arthur) [distracted driver collides with parked vehicle].)
    This chain of foreseeability is both short and direct. Accordingly, the "connection
    between [the vendor's] conduct and the injury suffered" by those alongside the road is not
    "too attenuated." (Cabral, supra, at p. 779.) There is also little uncertainty regarding
    whether and how a roadside victim suffers injury in this scenario.
    Bert's contends that intervening negligence by the vehicle's driver is not
    foreseeable. However, California law is to the contrary. In Lugtu v. California
    Highway Patrol (2001) 
    26 Cal. 4th 703
    , our Supreme Court ruled that a CHP officer
    owed to persons he stops a duty to pull them over in safe locations, even if the stopped
    party is subsequently injured by a third party's negligent driving. (Id., at pp. 716-717.)
    Courts reached similar conclusions in Jackson v. Ryder Truck Rental, Inc. (1993) 
    16 Cal. App. 4th 1830
     (Jackson) and Bloomberg, ruling that a truck rental company and an
    auto club, respectively, owed a duty not to strand their customers on the side of the road
    where those customers were later hit by negligent third parties. (Jackson, supra, at pp.
    7
    1837-1845; Bloomberg, supra, 162 Cal.App.3d at pp. 575-576; see also Weirum v. RKO
    General, Inc. (1975) 
    15 Cal. 3d 40
    , 47 [radio station has a duty not to encourage listeners
    to drive recklessly to win a contest].) To be sure, the court in Bryant refused to allow a
    tow truck driver injured by a negligent third party's driving to sue the drunk driver whose
    arrest prompted the need for a tow. (Bryant, supra, 32 Cal.App.4th at pp. 778-782.) But
    that ruling turned on policy concerns, and not on an inability to foresee the tow driver's
    injury. (Ibid.) We therefore conclude that the harm to persons on the roadside is a
    foreseeable result of a vendor's negligence in loading or securing cargo into a vehicle,
    even if the vehicle's driver is also negligent.
    2. Countervailing public policy considerations
    Because on a "clear judicial day[], . . . a court can foresee forever" (Thing v.
    La Chusa (1989) 
    48 Cal. 3d 644
    , 668), foreseeability is just the first step in deciding
    whether to recognize or exempt a duty. The next step is to assess whether other public
    policies militate against a duty notwithstanding the general foreseeability of the harm.
    (Bryant, supra, 32 Cal.App.4th at p. 778.) The pertinent public policy considerations are:
    "'[1] the moral blame attached to the defendant's conduct, [2] the policy of preventing
    future harm, [3] the extent of the burden to the defendant and consequences to the
    community of imposing a duty to exercise care with resulting liability for breach, and
    [4] the availability, cost, and prevalence of insurance for the risk involved.'" (Cabral,
    supra, 51 Cal.4th at p. 781, quoting Rowland, supra, 69 Cal.2d at p. 113.)
    Three of these policy considerations do not support the creation of a
    "categorical no duty rule." Although a vendor in this context is not engaged in
    intentional misconduct, "moral blame" still attaches to any negligence on its part.
    (Jackson, supra, 16 Cal.App.4th at p. 1844.) Bert's argues that White's marijuana use
    was more morally blameworthy, but we are dealing with the vendor's duty, which focuses
    on the vendor's culpability; White's relative blameworthiness is pertinent to the separate
    issue of causation. Imposing a duty to carefully load and secure cargo, with resulting
    liability for the negligent discharge of that duty, would be effective in discouraging
    negligence and thereby preventing future harm. Moreover, Bert's has not presented any
    8
    reason to believe that vendors' insurance policies are unavailable to cover liability for
    negligence in any loading and securing of cargo they voluntarily undertake for their
    customers.
    Bert's devotes its attention to the third factor, and presents four reasons why
    imposing a duty to load and secure cargo in a manner that will not distract a driver will be
    unduly burdensome and bad public policy. First and most broadly, Bert's argues that
    imposing this duty will discourage vendors from voluntarily agreeing to load and secure
    their customers' purchases, leaving the less-experienced customers to do it themselves
    and risking more accidents. Although vendors are potentially liable only if they
    voluntarily undertake to load and secure cargo (Bloomberg, supra, 162 Cal.App.3d at p.
    575), we are not persuaded vendors will refuse to help their customers load and secure
    their recent purchases just because the vendors are required to do so carefully. More
    broadly, as between customers and vendors, it is more efficient for vendors to be the
    repository of expertise in loading and securing cargo and to absorb the cost of insurance
    either through special fees for loading or as part of their general customer service.
    Second, Bert's contends that it will be difficult for a vendor to know what is
    distracting to a driver and hence impossible to guard against all such distractions. We
    agree that jurors will have to confront, on the facts of each case, whether a vendor's
    particular conduct was negligent and distracted the driver, but that is a question of breach
    for the jury—not the question of duty before us. (Cabral, supra, 51 Cal.4th at p. 772.)
    Third, Bert's asserts that imposing a duty will transform vendors into the
    guarantors of all risk related to the cargo. This is incorrect. The existence of a duty is
    but the first of many elements of a tort claim. (Bily v. Arthur Young & Co. (1992) 
    3 Cal. 4th 370
    , 397.) An injured plaintiff must also prove that the vendor breached the duty
    of care and proximately caused his or her injury. (Artiglio v. Corning Inc. (1998) 
    18 Cal. 4th 604
    , 613-614.) Bert's reliance on Delgado v. American Multi-Cinema, Inc.
    (1999) 
    72 Cal. App. 4th 1403
     and Dekens v. Underwriters Laboratories, Inc. (2003) 
    107 Cal. App. 4th 1177
    , is also misplaced. Those cases refused to recognize a duty in very
    different factual contexts. (Delgado, supra, at pp. 1406-1407 [theater owner did not owe
    9
    a duty to keep minors from seeing "R" rated movies so they would not be inspired by the
    movies to commit a murder]; Dekens, supra, at pp. 1181-1182 [lab that tested products
    for electrical safety did not owe a duty to guarantee those products did not cause
    asbestos-related harm].)
    Lastly, Bert's argues that two statutes—Vehicle Code sections 22350 and
    21701—embody a public policy against holding vendors liable for causing distractions.
    However, neither statute suggests or implies immunity for those who, by virtue of their
    negligence, distract drivers. (See Veh. Code, § 22350 [requiring drivers to drive no faster
    than conditions safely permit]; id., § 21701 [prohibiting willful interference with a
    driver's control of a vehicle].)
    Even if we assume that there are some countervailing policy reasons to
    immunize vendors, those reasons fall short of what is required to override the general rule
    in favor of imposing a duty for foreseeable injuries. California courts have given
    controlling weight to considerations of public policy only where the potential for tort
    liability directly leads to undesirable incentives or policy outcomes. (See Bryant, supra,
    32 Cal.App.4th at pp. 782-783 [persons with disabled vehicles do not owe a duty to tow
    truck drivers because it is "unwise to create an incentive for drivers whose cars are
    disabled to attempt self-help solutions rather than call for assistance"]; Lompoc Unified
    Sch. Dist. v. Super. Ct. (1993) 
    20 Cal. App. 4th 1688
    , 1697-1698 (Lompoc Unified)
    [landowners do not owe a duty to passing motorists not to distract them because it would
    obligate many landowners to build anti-distraction walls]; Parsons v. Crown Disposal
    Co. (1997) 
    15 Cal. 4th 456
    , 473-483 (Parsons) [garbage disposal companies do not owe a
    duty not to spook horses with their trucks because it would preclude the socially
    beneficial use of machinery in rural areas]; Gilmer v. Ellington (2008) 
    159 Cal. App. 4th 190
    , 198 (Gilmer) [persons yielding the right of way to motorists making a left turn do
    not owe a duty to those motorists to check for clear oncoming traffic in all lanes because
    it would be unwise to absolve left-turn makers of the duty to check traffic]; see also
    Williams v. Cingular Wireless (Ind. Ct. App. 2004) 
    809 N.E.2d 473
    , 478-479 (Williams)
    [cell phone companies do not owe a duty to guard against the negligence of buyers who
    10
    make calls while driving because it would discourage sale of cell phones].) Here, the
    potential for tort liability does not directly lead to undesirable incentives or policy
    outcomes.
    In short, public policy does not provide a justification for a "categorical no
    duty rule." (Cabral, supra, 51 Cal.4th at p. 772.)
    B. Vendor's inability to control the driver
    Bert's next argues that vendors owe no duty because, under California law,
    vendors have no "special relationship" with persons on or near the roadways and thus no
    obligation to act carefully in loading or securing cargo in a way that avoids injuring those
    persons. For support, Bert's cites Richards v. Stanley (1954) 
    43 Cal. 2d 60
    , 65; Southland
    Corporation v. Superior Court (1988) 
    203 Cal. App. 3d 656
    , 665-668; Tarasoff v. Regents
    of University of California (1976) 
    17 Cal. 3d 425
    , 435, superseded by statute Civ. Code, §
    43.92; Wiener v. Southcoast Childcare Centers, Inc. (2004) 
    32 Cal. 4th 1138
    , 1146.
    (Bert's also cites Bryant, supra, 
    32 Cal. App. 4th 770
    , but Bryant does not support this
    proposition.)
    The cases Bert's cites are inapposite. That is because they address tort
    liability in cases of "nonfeasance"—that is, where the defendant is accused of negligence
    in not preventing the negligent or intentional acts of a third party. Such authority is
    irrelevant in cases involving "malfeasance"—that is, where the defendant is accused of
    affirmatively doing something in a negligent way. (Jackson, supra, 16 Cal.App.4th at pp.
    1841-1842; Cabral, supra, 51 Cal.4th at pp. 778-779.) Because plaintiffs seek to hold
    Bert's liable for its misfeasance, the additional "special relationship" element present in
    nonfeasance cases does not apply.
    C. The immunity of a distraction's source
    Bert's also contends that California law already dictates that the person or
    entity responsible for distracting a driver can never be held liable in tort because the duty
    to control one's vehicle (including the duty not to be distracted) rests exclusively with the
    driver. We disagree.
    11
    California law does not support the broad rule of immunity Bert's proffers.
    Three of the cases Bert's cites simply declared the distracted driver liable and did not
    declare the source of the distraction categorically immune. (See Gray v. Brinkerhoff
    (1953) 
    41 Cal. 2d 180
    , 184 [not addressing source]; Mixon v. Pacific Gas & Electric Co.
    (2012) 
    207 Cal. App. 4th 124
    , 136 [same]; Truman v. Vargas (1969) 
    275 Cal. App. 2d 976
    ,
    980 [passenger did not contribute to accident by waving to pedestrian].) Two other cases
    Bert's cites addressed liability in unique and distinguishable contexts. Lompoc Unified,
    supra, 20 Cal.App.4th, page 1693, applies the longstanding rule that landowners have no
    duties beyond the boundaries of their property, and Coffman v. Kennedy (1977) 
    74 Cal. App. 3d 28
    , 32-33, refused to hold a passenger liable for her nonfeasance in not
    stopping her friend from driving while drunk. The remaining cases Bert's cites declined
    to hold the source of a distraction liable for public policy reasons, which we have already
    concluded are unpersuasive here. (See Lompoc Unified, supra, at pp. 1697-1698;
    Parsons, supra, 15 Cal.4th at pp. 469-470; Gilmer, supra, 159 Cal.App.4th at p. 198;
    Williams, supra, 809 N.E.2d at pp. 478-479.)
    For these reasons, we hold that vendors owe a duty of care to persons on or
    near the roadway who are injured as a result of the vendor's negligence in loading and
    securing cargo in a vehicle in a way that distracts the vehicle's driver. Accordingly, the
    trial court did not err in denying Bert's JNOV motion on this ground.
    II. White's Intervening Negligence Did Not Sever the
    Causal Link Between Bert's Negligence and Plaintiffs' Injuries
    In tort actions, the plaintiff must show that the defendant proximately
    caused his or her injuries. (United States Liability Ins. Co. v. Haidinger-Hayes, Inc.
    (1970) 
    1 Cal. 3d 586
    , 594.) Proximate causation has two components—one grounded in
    facts and the other in normative questions of policy. (PPG Indus., Inc. v. Transamerica
    Ins. Co. (1999) 
    20 Cal. 4th 310
    , 315-316 (PPG); Jackson, supra, 16 Cal.App.4th at p.
    1847.) Bert's attacks both.
    12
    A. Cause-in-fact
    At trial, a plaintiff in a negligence action must establish, as a factual matter,
    that the defendant's negligence was a cause-in-fact of his or her injury. (PPG, supra, 20
    Cal.4th at p. 315 [defendant's acts must be a "necessary antecedent"].) More than one
    cause-in-fact can contribute to an injury. (Raven H. v. Gamette (2007) 
    157 Cal. App. 4th 1017
    , 1025.) A defendant's negligence is considered a cause-in-fact if it is "'[a]
    substantial factor in causing harm,'" which means it is "'more than a remote or trivial
    factor.'" (Ibid.) Because this is a factual question, we review the record for substantial
    evidence. (Winograd v. American Broadcasting Co. (1998) 
    68 Cal. App. 4th 624
    , 632.)
    We accordingly resolve all evidentiary conflicts in favor of the jury's findings
    (Rutherford v. Owens-Illinois, Inc. (1997) 
    16 Cal. 4th 953
    , 964), and may overturn them
    only if "'. . . there is no room for a reasonable difference of opinion.' [Citations.]"
    (Bigbee, supra, 34 Cal.3d at p. 56.)
    Bert's argues that White was distracted solely by the popping noise, and
    contends that plaintiffs never established that it was more probable than not that the noise
    was caused by the negligently loaded or secured dirt bikes. (Saelzler v. Advanced Group
    400 (2001) 
    25 Cal. 4th 763
    , 776.) Bert's explains that the bikes could not have distracted
    White because plaintiffs' accident reconstruction expert conceded that he did not know
    what caused the popping sound and that no physical evidence showed that the bikes had
    ever moved; moreover, all three eyewitnesses to White's driving never saw the bikes
    move.
    Viewed in the light most favorable to the verdict, the evidence establishes
    that Bert's negligence in loading and securing the dirt bikes was a substantial factor in
    distracting White. The popping noise was not the only thing that distracted White. To
    the contrary, White had seen and felt the bikes hopping around in the bed of the truck
    prior to hearing the noise. Moreover, two of the three eyewitnesses admitted that they
    could not say whether the bikes moved. Under substantial evidence review, the absence
    of physical evidence of the bikes' movement is beside the point because the record
    contains White's testimony that he saw and felt the bikes move.
    13
    In sum, the evidence leaves room for a reasonable difference of opinion on
    the issue of cause-in-fact. Consequently, we may not upset the jury's finding on that
    issue.
    B. Superseding cause
    Even when a defendant's negligence is the factual antecedent to the
    plaintiff's injury, courts may for policy reasons deem the chain of causation severed.
    (PPG, supra, 20 Cal.4th at pp. 315-316; Ferguson v. Lieff, Cabraser, Heimann &
    Bernstein (2003) 
    30 Cal. 4th 1037
    , 1045.) Bert's asks us to do so here. Bert's argues that
    White's negligence in consuming marijuana before driving, and in taking his eyes off the
    roadway for too long, constitutes a "superseding cause" of the accident that should
    entirely cut off Bert's liability. Because this entails a normative question of policy, it is a
    question of law we review de novo. (Jackson, supra, 16 Cal.App.4th at p. 1847.)
    The intervening negligence (or even recklessness) of a third party will not
    be considered a superseding cause if it is a "normal response to a situation created by the
    defendant's conduct" (Stewart v. Cox (1961) 
    55 Cal. 2d 857
    , 864) and is therefore
    "'. . . within the scope of the reasons [for] imposing the duty upon [the defendant] to
    refrain from negligent conduct'" in the first place (Lugtu, supra, 26 Cal.4th at p. 725;
    Bigbee, supra, 34 Cal.3d at pp. 58-59.) A cause is superseding only when the third
    party's intervening negligence is "highly unusual or extraordinary" (Jackson, supra, 16
    Cal.App.4th at p. 1848), and "'. . . far beyond the risk the original tortfeasor should have
    foreseen . . . '" (Lugtu, supra, at p. 725). In making this assessment, we are to make a
    "'more focused, fact-specific' inquiry that takes into account a particular plaintiff's
    injuries and the particular defendant's conduct. [Citations.]" (Laabs, supra, 175
    Cal.App.4th at p. 1273.)
    While deplorable, White's intervening negligence was neither "highly
    unusual" nor "extraordinary." The reason for holding vendors liable for negligently
    loading and securing cargo in a vehicle is precisely because a poorly done job can distract
    the vehicle's driver. Moreover, it is not uncommon for drivers to be negligent, even
    intoxicated. (E.g., Bloomberg, supra, 162 Cal.App.3d at pp. 576-577.) In similar
    14
    circumstances, courts have repeatedly refused to deem the third party's intervening
    negligence a superseding cause. (See Jackson, supra, 16 Cal.App.4th at pp. 1847-1852
    [intervening negligence of driver hitting plaintiff stranded on roadside due to defendant's
    negligence not a superseding cause]; Bloomberg, supra, at pp. 576-577 [same].)
    The cases Bert's cites are not to the contrary. Arthur deals with cause-in-
    fact, not superseding cause. (Arthur, supra, 183 Cal.App.2d at pp. 487-488.) Whitton v.
    State of California (1979) 
    98 Cal. App. 3d 235
    , upheld a jury's finding that a CHP officer
    did not act negligently in selecting where to pull over a motorist who was subsequently
    hit by a drunk driver. (Id., at pp. 242-244.) This is a "question of breach" (Cabral,
    supra, 51 Cal.4th at p. 776), not causation. Lastly, the court in Schrimscher v. Bryson
    (1976) 
    58 Cal. App. 3d 660
    , refused to hold a drunk motorist liable for injuries a CHP
    officer suffered when a second drunk driver hit the officer while on the roadside. (Id., at
    pp. 664-665.) The court reasoned that "frequent[]" exposure to such roadside risks was
    part of the officer's "primary duties," such that imposing liability on the many motorists
    he stops would constitute an "unwarranted extension of liability." (Id., at p. 665.) These
    cases cast no doubt on our conclusion that a driver's negligence is well within the
    universe of risks that a vendor undertaking to load and secure cargo should foresee. Such
    negligence is not a superseding cause as a matter of law.
    III. The Trial Court Erred In Admitting the Toxicologist's
    Opinion that White Was Not Likely Impaired By Marijuana
    Bert's argues that the trial court abused its discretion in (1) ruling, under
    Evidence Code section 352, that Bert's could not cross-examine plaintiffs' toxicologist
    regarding the other drugs found in White's bloodstream soon after the accident; and
    (2) refusing to strike the toxicologist's opinion that White was a "chronic" user of
    marijuana and thus likely unimpaired at the time of the accident. (People v. Clark (2011)
    
    52 Cal. 4th 856
    , 893 [Evid. Code, § 352 rulings reviewed for abuse of discretion]; Korsak
    v. Atlas Hotels, Inc. (1992) 
    2 Cal. App. 4th 1516
    , 1523 [foundation for expert testimony
    reviewed for abuse of discretion].)
    15
    The trial court did not abuse its discretion in prohibiting cross-examination
    on the potential impairment caused by the other drugs in White's body. The probable
    effect of intoxicants other than alcohol is a topic "sufficiently beyond [the] common
    experience" of most jurors that expert testimony is required. (Evid. Code, § 801, subd.
    (a); People v. Cox (1990) 
    221 Cal. App. 3d 980
    , 989; People v. Balderas (1985) 
    41 Cal. 3d 144
    , 191-192, superseded on other grounds by Civ. Proc. Code, § 223.) Bert's elected not
    to call a toxicologist of its own to explain whether these other drugs were in sufficient
    concentrations to impair White. Further, given plaintiffs' toxicologist's statements during
    his pretrial deposition that the "data available" did not permit him to opine on whether the
    other drugs impaired White, Bert's also could not rely on plaintiff's toxicologist to render
    an opinion. Given this absence of a proper foundation, the trial court was well within its
    discretion to conclude that the probative value of any evidence on this topic was
    substantially outweighed by the danger of misleading the jury or confusing the issue.
    The trial court abused its discretion in allowing the jury to consider the
    toxicologist's opinion that White was a "chronic" marijuana user and hence unlikely to
    have been impaired by the prodigious amount of marijuana he consumed in the 24 hours
    leading up to the accident. The toxicologist defined a "chronic" user as a person (1) who
    used marijuana "for a long period of time"; and (2) who regularly drives while using
    marijuana. The toxicologist merely "assumed" that each prerequisite was true. He
    acknowledged, however, that his opinion would change if his assumptions were
    unfounded and that a non-chronic user would be impaired by the quantity of marijuana
    White had consumed. "'". . . Where an expert bases his conclusions upon assumptions
    which are not supported by the record, . . . his conclusion has no evidentiary value"'" and
    should be excluded. (Geffcken v. D'Andrea (2006) 
    137 Cal. App. 4th 128
    , 1311; White v.
    State of Cal. (1971) 
    21 Cal. App. 3d 738
    , 760; People v. Gardeley (1996) 
    14 Cal. 4th 605
    ,
    618.)
    The evidentiary basis for the toxicologist's first assumption is, as the trial
    court found, "thin"; for the second assumption, it is entirely absent. In validating his
    assumption that White was a long-term user of marijuana, the toxicologist pointed to two
    16
    pieces of evidence—namely, White's possession of a medical marijuana card for seven
    months prior to the accident, and the "quite high" levels of marijuana by-products in
    White's bloodstream. White's marijuana card ostensibly lends some support to the
    inference of long-term use (but says nothing about heavy use). The "high levels" of
    marijuana do not indicate long-term use because, as the toxicologist acknowledged, they
    reflect use in the days immediately prior to the accident. The toxicologist opined that this
    recent, heavy use could be equated with longer-term use, reasoning that heavy users are
    chronic users because chronic users are heavy users. This reasoning appears to be
    circular.
    Even accepting that this first assumption had some evidentiary foundation,
    plaintiffs adduced no evidence to support the second assumption underlying the
    toxicologist's opinion—namely, that White had repeatedly driven while using marijuana
    so as to no longer be impaired while doing so. The trial court's ruling was silent on this
    point. No evidence supports this assumption. To be sure, the evidence shows that White
    drove with marijuana in his system on the day of the accident in this case. But this is not
    evidence of repeated driving while using marijuana. In fact, White stated that he does not
    otherwise drive while using marijuana. Although a trial court enjoys broad discretion,
    that discretion "must be exercised within the limits the law permits" (Sargon Enterprises,
    Inc. v. University of So. Calif. (2012) 
    55 Cal. 4th 747
    , 773), and the law does not permit
    an expert opinion unconnected to the evidence in a case.
    This error was prejudicial because the apportionment of liability between
    Bert's and White was a close question. Although there was evidence that White was also
    negligent for taking his eyes away from the road for too long, a critical, linchpin issue in
    assigning fault was whether White's marijuana binge impaired his driving. This is
    undoubtedly why plaintiffs' counsel repeatedly touted in closing argument the
    toxicologist's opinion that White was not impaired.
    Plaintiffs (and White) offer four arguments to downplay the significance
    and impact of the toxicologist's opinion. First, they note that his opinion was very narrow
    and heavily qualified because he admitted that his opinion rested on assumptions, and
    17
    that his opinion was only as good as those assumptions. But that is precisely the point. It
    is because one of those assumptions is invalid that the expert's subsequent opinions that
    White was "most likely" a "chronic" user, and there was "no reason to think" otherwise,
    were prejudicial.
    Second, plaintiffs reason that the jury's allocation of 67 percent of
    the liability to White is proof that it rejected the toxicologist's opinion regarding White's
    non-impairment. We disagree. Because the jury was presented with other evidence of
    White's negligence such as his failure to keep his eyes on the road, the jury's decision to
    assign fault to White cannot be equated with a rejection of toxicologist's opinion. The
    jury's assignment of fault to White also means that it did not fully credit the opinion of
    plaintiffs' human factors expert that White's reaction was no different than a sober
    person's. More to the point, because the opinion was central to the issues and repeatedly
    emphasized by plaintiffs, it is reasonably probable that the opinion played a substantial
    role in the jury's decision of what percentage of liability to assign to White.
    Third, plaintiffs contend that the jury heard other evidence of White's
    impairment because it heard he was convicted of involuntary manslaughter while
    intoxicated. The significance of the conviction was undercut by the toxicologist's
    testimony that being "under the influence" was different from being "impaired." Thus,
    the brief reference to White's conviction without any explanation of its elements or
    factual basis did not do much, if anything, to obviate the otherwise significant impact of
    the expert's lengthy testimony regarding White's lack of "impairment."
    Lastly, plaintiffs note that Bert's argued in closing that White's level of
    impairment did not matter because White could be found negligent for other reasons.
    However, Bert's resort to an alternative argument in favor of its position in light of the
    trial court's ruling refusing to strike the toxicologist's opinion is a reasonable defensive
    tactic—not a concession of the opinion's insignificance.
    We therefore conclude that there is a "reasonable probability" that the jury's
    liability verdict was affected by the erroneous admission of the toxicologist's opinion that
    18
    White was a "chronic" user who was unlikely to be impaired at the time of the accident.
