    OPINION OF THE COURT
    __________
    ALDISERT, Circuit Judge.
    David W. Covell and Margaret Covell, who are
    plenary guardians of their adult son David F. Covell, appeal
    from a jury‟s verdict for the defendant in their products
    liability suit against Easton-Bell Sports, Inc. They urge us to
    order a new trial on the ground that the District Court erred
    by admitting evidence and charging the jury pursuant to
    sections 1 and 2 of the Restatement (Third) of Torts (1998),
    3
    rather than section 402A of the Restatement (Second) of Torts
    (1965). Having held in Berrier v. Simplicity Manufacturing,
    Inc., 
    563 F.3d 38
    (3d Cir. 2009), cert. denied, 
    130 S. Ct. 553
    (2009), that federal district courts applying Pennsylvania law
    to products liability cases should look to sections 1 and 2 of
    the Restatement (Third) of Torts, and seeing no reason to
    reverse course now, we will affirm.
    I.
    David F. Covell, a 36 year-old schoolteacher,
    sustained serious brain injuries when he was struck by a car
    while bicycling to work in 2007. Tragically, he is now so
    disabled that his parents (the “Covells”) have been appointed
    his legal guardians. In that capacity, they filed this products
    liability suit against Easton-Bell Sports, Inc. (“Bell”), which
    manufactured the “Giro Monza” bicycle helmet their son
    wore during the collision. Their suit, filed in the Pennsylvania
    Court of Common Pleas, alleged that the Giro Monza helmet
    was defectively designed and that it lacked adequate warnings
    about danger from impact to the helmet‟s edge. Bell removed
    the case to the United States District Court for the Eastern
    District of Pennsylvania, where the trial proceeded according
    to Pennsylvania substantive law.
    At trial, and over the Covells‟ strident objections, the
    District Court permitted Bell to introduce expert testimony
    that was based in part upon the United States Consumer
    Product Safety Commission‟s Safety Standard for Bicycle
    Helmets (the “CPSC Standard”). The CPSC Standard is an
    administrative regulation that provides an exacting set of
    guidelines for impact resistance, head covering, labels on
    helmets and helmet boxes, helmet resistance to temperature
    4
    and moisture, manufacturer recordkeeping, and much more.
    See 16 C.F.R. § 1203. Forced to respond to Bell‟s expert, the
    Covells offered their own expert testimony regarding the
    CPSC Standard. Ultimately, experts for both sides agreed that
    the CPSC Standard forms the starting point for any bicycle
    helmet design, and that the Giro Monza helmet satisfied the
    CPSC Standard in all respects.
    At the trial‟s conclusion, the District Court instructed
    the jury pursuant to sections 1 and 2 of the Restatement
    (Third) of Torts. The Court also instructed the jury that, in
    determining whether the Giro Monza helmet was or was not
    defective, it could consider evidence of standards or customs
    in the bicycle helmet industry, including the CPSC Standard.
    The jury returned a verdict for the defense, finding that the
    helmet was not defective. The Covells timely filed this
    appeal.
    II.
    The District Court had diversity jurisdiction pursuant
    to 28 U.S.C. § 1332(a)(1). We have jurisdiction pursuant to
    28 U.S.C. § 1291.
    We review issues of law de novo. Bear Mt. Orchards,
    Inc. v. Mich-Kim, Inc., 
    623 F.3d 163
    , 169 (3d Cir. 2010).
    This includes a District Court‟s decision to admit or exclude
    evidence pursuant to Pennsylvania law. Dillinger v.
    Caterpillar, Inc., 
    959 F.2d 430
    , 434-435 (3d Cir. 1992).
    III.
    The Covells call to our attention two assignments of
    5
    error. First, they contend that the District Court should not
    have applied the Restatement (Third) of Torts when
    instructing the jury and when admitting evidence of the CPSC
    Standard. Second, they contend that even if it was proper to
    apply the Restatement (Third) of Torts, the CPSC Standard
    was nonetheless inadmissible. We disagree and will affirm
    the District Court on both counts.
    A.
    We begin with the District Court‟s decisions to admit
    evidence and to instruct the jury pursuant to the Restatement
    (Third) and not the Restatement (Second) of Torts. We note at
    the outset that the question the Covells present—what is the
    law of Pennsylvania: section 402A of the Restatement
    (Second) of Torts, or sections 1 and 2 of the Restatement
    (Third) of Torts?—is one we laid to rest only 24 months ago
    in Berrier v. Simplicity Manufacturing, Inc., 
    563 F.3d 38
    , 40
    (3d Cir. 2009) (holding that if confronted with the question,
    the Supreme Court of Pennsylvania would apply sections 1
    and 2 of the Restatement (Third) of Torts to products liability
    cases), cert. denied, 
    130 S. Ct. 553
    (2009). After examining
    the contentions of the parties and the recent decisions of
    Pennsylvania‟s highest court, we conclude that the state of the
    law is no different now than it was when we decided Berrier.
    Rather than exhume the arguments and considerations we laid
    to rest there, we will apply stare decisis.
    1.
    In past products liability cases, the Supreme Court of
    Pennsylvania has looked to section 402A of the Restatement
    (Second) of Torts. E.g., Webb v. Zern, 
    220 A.2d 853
    , 854
    6
    (Pa. 1966) (“We hereby adopt the foregoing language [of
    § 402A] as the law of Pennsylvania.”). Section 402A makes
    sellers liable for harm caused to consumers by unreasonably
    dangerous products, even if the seller exercised reasonable
    care:
    (1) One who sells any product in a defective
    condition unreasonably dangerous to the
    user or consumer or to his property is
    subject to liability for physical harm thereby
    caused to the ultimate user or consumer, or
    to his property, if
    (a) the seller is engaged in the business of
    selling such a product, and
    (b) it is expected to and does reach the user
    or consumer without substantial change
    in the condition in which it is sold.
    (2) The rule stated in Subsection (1) applies
    although
    (a) the seller has exercised all possible care
    in the preparation and sale of his product,
    and
    (b) the user or consumer has not bought the
    product from or entered into any
    contractual relation with the seller.
    Restatement (Second) of Torts § 402A (1965). Section 402A
    thus creates a strict liability regime by insulating products
    7
    liability cases from negligence concepts. See 
    id. § 402A(2)(a);
    Azzarello v. Black Bros. Co., 
    391 A.2d 1020
    ,
    1025-1026 (Pa. 1978) (charging courts to avoid negligence
    concepts when instructing a jury pursuant to § 402A.).
    During the past 40 years, however, the Supreme Court
    of Pennsylvania has repeatedly addressed confusion arising
    from a core conflict in the structure of section 402A itself:
    Section 402A instructs courts to ignore evidence that the
    seller “exercised all possible care in the preparation and sale
    of his product,” § 402A(2)(a), yet imposes liability only for
    products that are “unreasonably dangerous,” § 402A(1). In
    many cases it is difficult or impossible to determine whether a
    product is “unreasonably dangerous” to consumers without
    reference to evidence that the seller did or did not exercise
    “care in the preparation” of the product. See Schmidt v.
    Boardman Co., 
    11 A.3d 924
    , 940 (Pa. 2011) (“This no-
    negligence-in-strict-liability rubric has resulted in material
    ambiguities     and      inconsistency     in    Pennsylvania‟s
    procedure.”); see also Phillips v. Cricket Lighters, 
    841 A.2d 1000
    , 1015-1016 (Pa. 2003) (Saylor, J., dissenting).
    Nonetheless, the Supreme Court of Pennsylvania has
    endeavored to segregate strict liability‟s “product-oriented”
    analysis from the “conduct-oriented” analysis of negligence.
    
    Phillips, 841 A.2d at 1006
    (“[W]e have remained steadfast in
    our proclamations that negligence concepts should not be
    imported into strict liability law . . .”). In so doing,
    Pennsylvania‟s high court has stated repeatedly that
    negligence concepts have no place in products liability. E.g.,
    id.; 
    Azzarello, 391 A.2d at 1025-1026
    . That endeavor has not
    always been successful, see Davis v. Berwind Corp., 
    690 A.2d 186
    , 190 (Pa. 1997) (holding that if a “product has
    8
    reached the user or consumer with substantial change,”
    liability depends upon “whether the manufacturer could have
    reasonably expected or foreseen such an alteration of its
    product.”) (emphasis added), nor has it been uniformly
    embraced by the Justices of that Court, see 
    Schmidt, 11 A.3d at 940
    (disapproving of Pennsylvania‟s “almost unfathomable
    approach to products litigation”) (quotation omitted).
    The American Law Institute responded to the core
    conflict in section 402A when it published the Restatement
    (Third) of Torts. Sections 1 and 2 of the Restatement (Third)
    of Torts abandon entirely the negligence-versus-strict-liability
    distinction that has caused so much trouble in Pennsylvania:
    § 1: Liability of Commercial Seller or
    Distributor for Harm Caused by
    Defective Products
    One engaged in the business of selling or
    otherwise distributing products who sells
    or distributes a defective product is subject
    to liability for harm to persons or property
    caused by the defect.
    § 2: Categories of Product Defect
    A product is defective when, at the time of
    sale or distribution, it contains a
    manufacturing defect, is defective in
    design, or is defective because of
    inadequate instructions or warnings. A
    product:
    (a) contains a manufacturing defect when
    9
    the product departs from its intended
    design even though all possible care
    was exercised in the preparation and
    marketing of the product;
    (b) is defective in design when the
    foreseeable risks of harm posed by the
    product could have been reduced or
    avoided by the adoption of a
    reasonable alternative design by the
    seller or other distributor, or a
    predecessor in the commercial chain of
    distribution, and the omission of the
    alternative design renders the product
    not reasonably safe;
    (c) is defective because of inadequate
    instructions or warnings when the
    foreseeable risks of harm posed by the
    product could have been reduced or
    avoided by the provision of reasonable
    instructions or warnings by the seller or
    other distributor, or a predecessor in
    the commercial chain of distribution,
    and the omission of the instructions or
    warnings renders the product not
    reasonably safe.
    Restatement (Third) of Torts §§ 1-2 (1998).
    Section 1 thus makes sellers liable only for the sale of
    products that are “defective,” and section 2 provides that a
    product may qualify as “defective” if it meets one of three
    10
    sets of criteria. The criteria—which incorporate negligence
    concepts such as “foreseeable risk” and “care” directly into
    the definition of “defective”—amount to an express rejection
    of the “no negligence in products liability” regime that the
    Supreme Court of Pennsylvania has endorsed in cases like
    
    Azzarello, 391 A.2d at 1025-1026
    . Several Justices of the
    Supreme Court of Pennsylvania have expressed the view that
    section 402A‟s approach is antiquated and should be
    replaced. See, e.g., 
    Phillips, 841 A.2d at 1015-1016
    (Saylor,
    J., Castille, J., & Eakin, J., concurring) (“I believe that the
    time has come for this Court, in the manner of so many other
    jurisdictions, to expressly recognize the essential role of risk-
    utility balancing, a concept derived from negligence doctrine,
    in design defect litigation.”). Whether or when that Court will
    move from the Restatement (Second) to the Restatement
    (Third) of Torts are questions that have engendered much
    debate.
    They are also questions that have challenged this
    Court. In Berrier, we noted that the Supreme Court of
    Pennsylvania had not yet answered whether bystanders could
    recover on design defect claims. This question, in turn,
    required us to determine whether products liability cases are
    governed by the Restatement (Second) or the Restatement
    (Third) of Torts, and we stated that “[i]n the absence of a
    controlling decision by the Pennsylvania Supreme Court, a
    federal court applying that state‟s substantive law must
    predict how Pennsylvania‟s highest court would decide this
    
    case.” 563 F.3d at 45-46
    . After reviewing “relevant state
    precedents, analogous decisions, considered dicta, scholarly
    works, and . . . other reliable data,” 
    id. at 46,
    we concluded
    that “if the Pennsylvania Supreme Court were confronted
    with this issue, it would adopt the Restatement (Third) of
    11
    Torts, §§ 1 and 2,” 
    id. at 40.
    Thus, we held that federal courts
    sitting in diversity and applying Pennsylvania law to products
    liability cases should look to sections 1 and 2 of the
    Restatement (Third) of Torts. 
    Id. The precedential
    holding in
    Berrier, as set forth above, represents this Court‟s view of
    Pennsylvania‟s products liability law.
    2.
    The District Court followed Berrier. In so doing it
    admitted evidence of the CPSC Standard as relevant to the
    amount of care Bell exercised, and it instructed the jury
    according to the framework set forth in sections 1 and 2 of the
    Restatement (Third) of Torts. The Covells contend that these
    decisions by the District Court were erroneous, because they
    would be improper under section 402A of the Restatement
    (Second) of Torts. They maintain that section 402A “has been
    the law in Pennsylvania since it was adopted in Webb v. Zern,
    [
    220 A.2d 853
    (Pa. 1966)]” and that “[n]o decision of the
    Pennsylvania Supreme Court has changed this.” If the District
    Court had applied the Restatement (Second) of Torts, it
    would not have permitted Bell to admit evidence of the CPSC
    Standard (because due care is irrelevant under the
    Restatement (Second) of Torts), and it would not have
    instructed the jury to consider whether the Giro Monza
    helmet was “unreasonably” dangerous (because the only
    relevant inquiry under the Restatement (Second) of Torts is
    whether the product itself was defective). The Covells
    maintain that each of these decisions by the District Court
    violated the doctrine of Erie Railroad Co. v. Tompkins, 
    304 U.S. 64
    (1938), as set forth in Van Dusen v. Barrack, 
    376 U.S. 612
    (1964), which requires federal courts sitting in
    diversity to apply state substantive 
    law. 376 U.S. at 638
    12
    (Stating that, “[t]he nub of the policy that underlies [Erie] is
    that . . . a suit by a non-resident litigant in a federal court
    instead of in a State court a block away, should not lead to a
    substantially different result.”). In short, the Covells‟ position
    is that section 402A is the law of Pennsylvania, and that when
    the District Court applied the Restatement (Third) of Torts it
    permitted Bell to illicitly “utilize a transfer to achieve a result
    in federal court which could not have been achieved in the
    courts of the State where the action was filed.” 
    Id. In response,
    Bell directs us to our decision in 
    Berrier, 563 F.3d at 40
    , wherein we held that if confronted with the
    issue, the Supreme Court of Pennsylvania would apply
    sections 1 and 2 of the Restatement (Third) and not section
    402A of the Restatement (Second) of Torts. Such predictions
    by a federal court sitting in diversity are permissible absent a
    controlling decision by a state‟s highest court. Nationwide
    Mut. Ins. Co. v. Buffetta, 
    230 F.3d 634
    , 637 (3d Cir. 2000).
    Bell‟s position is that the District Court in this case did not
    err, because it followed Berrier‟s precedential prediction of
    Pennsylvania law.
    We will affirm the District Court‟s application of
    sections 1 and 2 of the Restatement (Third) of Torts. Much of
    the briefing from the parties, and all of the briefing from the
    amici, is devoted to which Restatement of Torts is best as a
    matter of policy, and which most logically extends the
    decisions of the Supreme Court of Pennsylvania—all of
    which are issues we waded through and resolved only two
    years ago when we decided Berrier. This means that,
    notwithstanding the volume of briefing in this case, the
    dispositive question we must answer is straightforward: do
    we follow Berrier?
    13
    3.
    We will follow Berrier, and affirm the District Court.
    First, our Internal Operating Procedures instruct us to follow
    prior panels‟ decisions:
    Policy of Avoiding Intra-circuit Conflict of
    Precedent.
    It is the tradition of this court that the holding of
    a panel in a precedential opinion is binding on
    subsequent panels. Thus, no subsequent panel
    overrules the holding in a precedential opinion
    of a previous panel. Court en banc consideration
    is required to do so.
    3d Cir. I.O.P. 9.1 (2010).
    “Although a panel of this court is bound by, and lacks
    authority to overrule, a published decision of a prior panel, a
    panel may reevaluate a precedent in light of intervening
    authority,” including intervening decisions of state law but its
    highest court. Reich v. D.M. Sabia Co., 
    90 F.3d 854
    , 858 (3d.
    Cir. 1996) (internal citation omitted). In this vein, the Covells
    direct our attention to Bugosh v. I.U. North America, Inc.,
    
    942 A.2d 897
    (Pa. 2008), appeal dismissed as improvidently
    granted by 
    971 A.2d 1228
    (Pa. 2009). The Bugosh petitioner
    had sought a holding from the Supreme Court of
    Pennsylvania declaring that the Restatement (Third) and not
    the Restatement (Second) of Torts reflects the law of
    Pennsylvania. The Court granted allocatur on the issue in
    2008, but in 2009 dismissed the appeal as improvidently
    14
    granted. Bugosh, 
    971 A.2d 1228
    . The Covells urge us to hold
    that the dismissal of Bugosh indicates the Supreme Court of
    Pennsylvania‟s contentment with the Restatement (Second) of
    Torts.
    We will not do so. Reading the tea leaves of a
    certiorari or allocatur dismissal is risky business; one could
    just as reasonably conclude that the dismissal here indicates
    the Court‟s approval of Berrier as much as it indicates its
    approval of section 402A. That is why the Supreme Court of
    Pennsylvania has warned against reading between the lines of
    an allocatur dismissal:
    In the circumstance where we have accepted an
    issue by granting allowance of appeal, and this
    Court, after conducting our review of the issue,
    enters an order dismissing the appeal as having
    been improvidently granted, the effect is as
    though this Court never granted allowance of
    appeal. In other words, a dismissal as being
    improvidently granted has the exact same effect
    as if this Court had denied the petition for
    allowance of appeal (allocatur) in the first place.
    Where we dismiss an appeal as improvidently
    granted, the lower tribunal‟s opinion and order
    stand as a decision of that court and this Court‟s
    order has no precedential value.
    Commonwealth v. Tilghman, 
    673 A.2d 898
    , 904 (Pa. 1996)
    (emphasis in original); see also Salazar v. Allstate Ins. Co.,
    
    702 A.2d 1038
    , 1043 n.10 (Pa. 1997) (“[T]he fact that this
    court denied allowance of appeal . . . is no indication of our
    endorsement of the reasoning used by the Superior Court.”).
    15
    We therefore conclude that, in light of the Supreme Court of
    Pennsylvania‟s directives in Tilghman and Salazar, the
    Bugosh appeal was an intervening event, but not an
    intervening “authority” sufficient to revisit our holding in
    Berrier.
    Given that Bugosh is of no consequence, we conclude
    that the state of the law in Pennsylvania is exactly as it was
    when we decided Berrier. Absent a change in Pennsylvania‟s
    law, we see no reason to upset our precedent. Applying
    Berrier, we hold that the District Court did not err in using the
    Restatement (Third) of Torts to guide its decisions to admit
    evidence, and to frame its jury instructions.
    B.
    The Covells‟ fallback contention is that even if
    sections 1 and 2 of the Restatement (Third) of Torts were the
    law of Pennsylvania (i.e., even if the jury instructions in this
    case were correct), the District Court nonetheless erred by
    admitting evidence of the CPSC Standard. The Covells point
    out that the CPSC Standard is an “industry regulation” as
    described in section 4 of the Restatement (Third) of Torts,
    which—unlike sections 1 and 2—has not been cited or
    discussed by the Supreme Court of Pennsylvania. Cf. 
    Berrier, 563 F.3d at 40
    (holding only that the Supreme Court of
    Pennsylvania would apply sections 1 and 2 of the
    Restatement (Third) of Torts to products liability cases), The
    Covells maintain that if we affirm the District Court on this
    point we will apply section 4 before the Supreme Court of
    Pennsylvania does so—something to be avoided in a diversity
    case. Cf. Van 
    Dusen, 376 U.S. at 638
    . We conclude that we
    need break no new ground today; we will affirm the District
    16
    Court without resort to section 4 of the Restatement (Third)
    of Torts because the CPSC Standard was admissible pursuant
    to section 2.
    The Covells are correct that most jurisdictions
    applying the Restatement (Third) of Torts to products liability
    cases hold that evidence of compliance with product
    regulations is admissible to prove whether or not a product is
    defective. E.g., Doyle v. Volkswagenwerk Aktiengesellschaft,
    
    481 S.E.2d 518
    , 521 (Ga. 1997). Courts in jurisdictions that
    have incorporated the entirety of the Restatement (Third) of
    Torts are free to admit such evidence under section 4, which
    provides:
    Noncompliance and Compliance with
    Product Safety Statutes or Regulations
    In connection with liability for defective design
    or inadequate instructions or warnings:
    (a) a product‟s noncompliance with an
    applicable product safety statute or
    administrative regulation renders the product
    defective with respect to the risk sought to
    be reduced by the statute or regulation; and
    (b) a product‟s compliance with an applicable
    product safety standard or administrative
    regulation is properly considered in
    determining whether the product is defective
    with respect to the risks sought to be
    reduced by the statute or regulation, but such
    compliance does not preclude as a matter of
    17
    law a finding of a product defect.
    The District Court admitted such evidence in this case.
    It permitted Bell to demonstrate its compliance with the
    CPSC Standard, 16 C.F.R. § 1203, as evidence that its helmet
    was not “defective,” under section 2 of the Restatement
    (Third) of Torts.
    The Covells contend that this was reversible error
    because section 4, not section 2, of the Restatement (Third) of
    Torts deals with governmental regulations, and—setting aside
    all debate over the validity of our holding in Berrier—there
    has been no indication from the Supreme Court of
    Pennsylvania that it would apply section 4. Because section 4
    is not in play, they contend, there was no basis upon which
    the District Court could have admitted evidence of Bell‟s
    compliance with the CPSC Standard, regardless of which
    version of the Restatement it applied. For support, they rely
    upon Lewis v. Coffing Hoist Division, Duff-Norton, Co., 
    528 A.2d 590
    , 594 (Pa. 1987), which applied section 402A and
    held that evidence of industry practice or regulation is
    inadmissible in products liability cases. The Lewis Court
    reasoned that to admit industry practice and regulation in
    products liability cases would be to “improperly [bring] into
    the case concepts of negligence law.” 
    Id. We are
    not persuaded. As a threshold matter, we
    believe that to cite to Lewis is to beg the very question at
    issue in this appeal: may district courts applying Pennsylvania
    law to products liability cases admit evidence that is relevant
    to negligence-type concepts, like duty of care or
    forseeability? To rely upon Lewis (handed down in 1987,
    during the zenith of Pennsylvania‟s no-negligence-in-strict-
    18
    liability regime) would be to assume the question out of
    existence, because Lewis based its reasoning entirely upon
    the premise that there shall be no negligence in products
    liability. See 
    id. No longer
    can a court assume that premise is
    true—see 
    Davis, 690 A.2d at 186
    (applying certain
    negligence principles to products liability)—which means, by
    extension, that no longer can a court assume Lewis accurately
    reflects the law of Pennsylvania, cf. Aetna Life & Casualty
    Co. v. Barthelemy, 
    33 F.3d 189
    , 193 (3d Cir. 1994) (“Where
    stops the reason, there stops the rule.” (quoting Karl N.
    Llewellyn, Jurisprudence: Realism in Theory and Practice
    217 (1962))).
    Whether the District Court erred in admitting evidence
    of the CPSC Standard thus depends not on pre-Berrier
    decisions like Lewis, but upon the post-Berrier legal
    framework that controls Pennsylvania products liability cases.
    In our view, it is highly unlikely that the Supreme Court of
    Pennsylvania would apply sections 1 and 2 of the
    Restatement (Third) of Torts (allowing negligence concepts),
    but not section 4 (providing for relevant industry regulation).
    We have difficulty imagining a negligence-friendly products
    liability regime that ignores compliance or non-compliance
    with pertinent state and federal regulations. At any rate, we
    need not determine whether the Supreme Court of
    Pennsylvania would adopt section 4 because we agree with
    Bell that evidence of its compliance with the CPSC Standard
    was relevant to section 2 of the Restatement (Third) of Torts
    as applied in Berrier, and was admissible pursuant to the
    Federal Rules of Evidence. The relevancy provisions of the
    Federal Rules of Evidence control in this case because they
    are “arguably procedural.” See Kelly v. Crown Equip. Co.,
    
    970 F.2d 1273
    , 1278 (3d Cir. 1992) (Federal Rules of
    19
    Evidence that are “arguably procedural” control in diversity
    actions, “notwithstanding Pennsylvania law to the contrary.”).
    Under the Federal Rules of Evidence, “„[r]elevant evidence‟
    means evidence having any tendency to make the existence of
    any fact that is of consequence to the determination of the
    action more probable or less probable than it would be
    without the evidence,” Rule 401, and “[a]ll relevant evidence
    is admissible, except as otherwise provided by the
    Constitution of the United States, by Act of Congress, by
    these rules, or by other rules prescribed by the Supreme Court
    pursuant to statutory authority,” Rule 402.
    Applying this standard, we conclude that evidence of
    Bell‟s compliance with the CPSC Standard was relevant to
    the jury‟s inquiry because it went to at least two facts of
    consequence under section 2 of the Restatement (Third) of
    Torts, section 2. First, the CPSC Standard sets forth detailed
    rules for impact resistance and testing, and for labels and
    warning—both on the helmet and its sales packaging.
    Evidence that Bell complied with the CPSC Standard‟s
    requirement for impact resistance testing makes it “more
    probable,” Rule 401, that “all possible care was exercised in
    the preparation and marketing of the product,” Restatement
    (Third) of Torts § 2(a). Second, evidence that Bell complied
    with the CPSC Standard makes it “less probable,” Rule 401,
    that “the foreseeable risks of harm posed by the product could
    have been reduced or avoided by the provision of reasonable
    instructions or warnings,” Restatement (Third) of Torts
    § 2(c). Of course, such evidence was not conclusive on these
    points, but it was relevant and therefore presumptively
    admissible under the Federal Rules.
    Our conclusion in this respect—i.e., that industry
    20
    standards and government regulations are relevant to facts of
    consequence in this case—is also in line with the
    Commentary to section 2 of the Restatement (Third) of Torts.
    Comment (b) explicitly states that industry regulations may
    be relevant to a plaintiff‟s case under section 2, irrespective of
    section 4:
    Section 4, dealing with violations of statutory
    and regulatory norms, also provides an alternate
    method of establishing defect. A plaintiff is not
    required to establish the standard for design or
    warning under § 2, but merely to identify a
    government-imposed standard.
    
    Id. § 2
    comment (b). Further, comment (d) states that
    defendants may admit evidence of industry practice to show
    that an alternative design would not have made their product
    safer:
    The defendant is thus allowed to introduce
    evidence with regard to industry practice that
    bears on whether the omission of an alternative
    design rendered the product not reasonably safe.
    While such evidence is admissible, it is not
    necessarily dispositive.
    
    Id. § 2
    comment (d). The commentary to section 2 of the
    Restatement (Third) of Torts thus buttresses our conclusion
    that evidence related to the CPSC Standard was properly
    admitted in this case.
    In sum, we conclude that we need not consider
    whether evidence of the CPSC Standard was admissible
    21
    pursuant to section 4 of the Restatement (Third) of Torts
    because in this case the evidence was admissible pursuant to
    section 2, as applied in Berrier. We will therefore affirm the
    District Court.
    *****
    We have considered all of the arguments advanced by
    the parties and conclude that no further discussion is
    necessary. The judgment of the District Court will be
    AFFIRMED.
