    SUMMARY *
    Federal Motor Carrier Safety Administration
    The panel denied petitions for review of the Federal
    Motor Carrier Safety Administration (“FMCSA”)’s
    determination that federal law preempted California’s meal
    and rest break rules (the “MRB rules”), as applied to drivers
    of property-carrying commercial motor vehicles who are
    subject to the FMCSA’s own rest break regulations.
    The FMCSA only has the authority to review for
    preemption State laws and regulations “on commercial
    motor vehicle safety.” 
    49 U.S.C. § 31141
    (c).
    The panel held the agency’s interpretation of the statute
    and the phrase “on commercial motor vehicle safety”
    merited deference under Chevron, U.S.A., Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
     (1984),
    where the FMCSA acknowledged that it was departing from
    its 2008 interpretation of § 31141 and provided a reasoned
    analysis why it was doing so. The panel rejected petitioners’
    arguments that Chevron deference was inapplicable.
    Turning to Chevron’s two-step framework, the panel
    held that even assuming petitioners identified a potential
    ambiguity in the statute, the agency’s reading was a
    permissible one. The FMCSA reasonably determined that a
    State law “on commercial motor vehicle safety” was one that
    “imposes requirements in an area of regulations that is

    IBT V. FMCSA                         5
    already addressed by a regulation promulgated under
    [section] 31136.” 83 Fed. Reg. at 67,473 (Dec. 28, 2018).
    The FMCSA’s 2018 preemption decision also reasonably
    relied on Congress’s stated interest in uniformity of
    regulation. The fact that California regulated meal and rest
    breaks in a variety of industries did not compel the
    conclusion that the MRB rules were not “on commercial
    motor vehicle safety.” Finally, the panel held that the
    decision in Dilts v. Penske Logistics, LLC, 
    769 F.3d 637
     (9th
    Cir. 2014), did not foreclose the FMCSA’s interpretation.
    The panel concluded that the FMCSA permissibly
    determined that California’s MRB rules were State
    regulations “on commercial motor vehicle safety,” so that
    they were within the agency’s preemption authority.
    The panel held that the FMCSA’s determination that the
    MRB rules were “additional to or more stringent than” the
    federal regulation was reasonable and supported. 
    49 U.S.C. § 31141
    (c)(1). The FMCSA reached this conclusion
    because California required more breaks, more often and
    with less flexibility as to timing. The panel rejected
    petitioners’ challenges to this determination.
    The panel held that the FMCSA did not act arbitrarily or
    capriciously in finding that enforcement of the MRB rules
    “would cause an unreasonable burden on interstate
    commerce.” 
    49 U.S.C. § 31141
    (c)(4)(C). Petitioners’
    counterarguments did not show that the agency acted
    arbitrarily or capriciously.

    OPINION
    BRESS, Circuit Judge:
    The Federal Motor Carrier Safety Administration
    (FMCSA), an agency within the Department of
    Transportation, is tasked with issuing regulations on
    commercial motor vehicle safety. The FMCSA also has
    authority to determine that state laws on commercial motor
    vehicle safety are preempted, based on criteria Congress has
    specified. In this case, the FMCSA determined that federal
    law preempts California’s meal and rest break rules, known
    as the “MRB rules,” as applied to drivers of property-
    carrying commercial motor vehicles who are subject to the
    FMCSA’s own rest break regulations. Compared to federal
    safety regulations, California’s MRB rules generally require
    that employers allow commercial truck drivers to take more
    rest breaks, at greater frequency, and with less flexibility as
    to when breaks occur.
    IBT V. FMCSA                          9
    California’s Labor Commissioner, certain labor
    organizations, and others now petition for review of the
    FMCSA’s preemption determination. Because the agency’s
    decision reflects a permissible interpretation of the Motor
    Carrier Safety Act of 1984 and is not arbitrary or capricious,
    we deny the petitions for review.
    I
    A
    Congress passed the Motor Carrier Safety Act of 1984
    “to promote the safe operation of commercial motor
    vehicles, [and] to minimize dangers to the health of operators
    of commercial motor vehicles and other employees.” Pub.
    L. No. 98-554, tit. II, 
    98 Stat. 2832
    , § 202 (originally
    codified at 49 U.S.C. app. 2501). Under the Act, the
    Secretary of Transportation “shall prescribe regulations on
    commercial motor vehicle safety” that contain “minimum
    safety standards for commercial motor vehicles.” 
    49 U.S.C. § 31136
    (a). Among other things, federal regulations “shall
    ensure” that “the responsibilities imposed on operators of
    commercial motor vehicles do not impair their ability to
    operate the vehicles safely.” 
    Id.
     § 31136(a)(2).
    The Act also gives the Secretary the express power to
    preempt State law: “A State may not enforce a State law or
    regulation on commercial motor vehicle safety that the
    Secretary of Transportation decides under this section may
    not be enforced.” Id. § 31141(a). To carry out this duty,
    “[t]he Secretary shall review State laws and regulations on
    commercial motor vehicle safety.” Id. § 31141(c)(1).
    The statute provides a multi-step process that the
    Secretary must follow in conducting this review. The
    Secretary must first compare the State law or regulation at
    10                     IBT V. FMCSA
    issue to a regulation prescribed by the Secretary under
    
    49 U.S.C. § 31136
     and decide whether the State law “has the
    same effect as,” “is less stringent than,” or “is additional to
    or more stringent than” the federal regulation.              
    Id.
    § 31141(c)(1). If the Secretary decides a State law or
    regulation has the “same effect” as the federal regulation,
    “the State law or regulation may be enforced.” Id.
    § 31141(c)(2). If a State law is less stringent than the federal
    regulation, “the State law or regulation may not be
    enforced.” Id. § 31141(c)(3).
    If the Secretary decides that a State law is “additional to
    or more stringent” than a federal regulation, another decision
    tree applies. At that point, the State law “may be enforced
    unless the Secretary also decides that — (A) the State law or
    regulation has no safety benefit; (B) the State law or
    regulation is incompatible with the regulation prescribed by
    the Secretary; or (C) enforcement of the State law or
    regulation would cause an unreasonable burden on interstate
    commerce.” Id. § 31141(c)(4). When considering the
    burden on interstate commerce, “the Secretary may consider
    the effect on interstate commerce of implementation of that
    law or regulation with the implementation of all similar laws
    and regulations of other States.” Id. § 31141(c)(5).
    The Secretary has delegated its rulemaking and
    preemption authority to the Administrator of the FMCSA.
    
    49 C.F.R. § 1.87
    (f).
    B
    Federal regulations impose limits on the driving time for
    commercial motor vehicle drivers. These are known as the
    hours-of-service regulations. Under federal law, a property-
    carrying commercial motor vehicle driver “may not drive
    without first taking 10 consecutive hours off duty,”
    IBT V. FMCSA                               11
    
    49 C.F.R. § 395.3
    (a)(1) (2018), 1 and “may not drive after the
    end of the 14-consecutive-hour period without first taking
    10 consecutive hours off duty,” 
    id.
     § 395.3(a)(2). Within
    that 14-hour period, a driver may only drive 11 hours. Id.
    § 395.3(a)(3)(i). Federal regulations also impose weekly
    driving limits. Id. § 395.3(b) (prohibiting a driver from
    being on duty for more than 60 or 70 hours in seven or eight
    consecutive days, respectively).
    In 2011, the FMCSA revised the federal hours-of-service
    regulations and adopted the rules on breaks for truck drivers
    that form the basis for the FMCSA’s 2018 decision to
    preempt California’s MRB rules. See Hours of Service of
    Drivers, 
    76 Fed. Reg. 81,134
    , 81,188 (Dec. 27, 2011)
    (codified at 
    49 C.F.R. § 395.3
    ). Except for certain “short-
    haul” drivers, a property-carrying commercial motor vehicle
    driver working more than eight hours must take at least one
    30-minute break during the first eight hours, although the
    driver has flexibility as to when the break occurs. 
    49 C.F.R. § 395.3
    (a)(3)(ii). That 30-minute break can be spent “off-
    duty” or in a “sleeper berth.” 
    Id.
     2 The 2011 break
    requirement supplemented longstanding federal regulations
    1
    The FMCSA revised 
    49 C.F.R. § 395.3
     in 2019, and again in 2020.
    See Hours of Service of Drivers—Restart Provision, 
    84 Fed. Reg. 48,077
    (Sept. 12, 2019); Hours of Service of Drivers, 
    85 Fed. Reg. 33,396
     (June
    1, 2020). In this opinion, we cite the 2018 version of the regulation, the
    rule in place at the time of the FMCSA’s preemption determination. But
    the 2019 and 2020 changes do not affect the preemption analysis.
    2
    Under the 2020 revisions to the regulation, the 30-minute break
    requirement now applies “only when a driver has driven (instead of
    having been on-duty) for a period of 8 hours without at least a 30-minute
    non-driving interruption.” 85 Fed. Reg. at 33,396. Additionally, a driver
    can now satisfy the break requirement with “any non-driving period of
    30 minutes, i.e., on-duty, off-duty, or sleeper berth time.” Id.; see also
    
    49 C.F.R. § 395.3
    (a)(3)(ii) (2020).

    prohibiting a driver from operating a commercial motor
    vehicle if too fatigued or unable to safely drive. 
    49 C.F.R. § 392.3
    . Employers may not coerce drivers to violate this
    rule or the hours-of-service rules. 
    Id.
     § 390.6. The federal
    regulations do not require other breaks.
    The California rules are different. California’s rules are
    contained in wage orders issued by the State’s Industrial
    Welfare Commission (IWC), which is tasked with protecting
    workers’ “health, safety, and welfare.” Martinez v. Combs,
    
    231 P.3d 259
    , 271 (Cal. 2010) (quoting 
    Cal. Lab. Code § 1173
    ). To that end, the IWC has issued eighteen wage
    orders, mostly on an industry-wide or occupation-wide
    basis. 
    Cal. Code Regs. tit. 8, §§ 11010
    –11170; Martinez,
    
    231 P.3d at
    272–73. These orders cover all employees in
    California unless they are specifically exempted. See
    Brinker Rest. Corp. v. Superior Court, 
    273 P.3d 513
    , 521 n.1
    (Cal. 2012); Martinez, 
    231 P.3d at
    273 & n.24; 
    Cal. Code Regs. tit. 8, § 11170
    (1)(A). Seventeen IWC orders contain
    meal period requirements and sixteen contain rest period
    requirements. See 
    Cal. Code Regs. tit. 8, §§ 11010
    –11170.
    Wage Order 9-2001 applies to “all persons employed in
    the transportation industry,” which necessarily includes
    property-carrying commercial truck drivers. 
    Id.
     § 11090(1).
    Under the order, an employee working more than five hours
    a day is entitled to a “meal period of not less than
    30 minutes.” Id. § 11090(11)(A). If, however, “a work
    period of not more than six (6) hours will complete the day’s
    work the meal period may be waived by mutual consent of
    the employer and the employee.” Id. An employee is
    entitled to “a second meal period of not less than 30 minutes”
    when working more than 10 hours in a day.                  Id.
    § 11090(11)(B). The employee and employer can only agree
    to waive the second meal break if the employee does not
    IBT V. FMCSA                        13
    work more than 12 hours in a day and did not waive the first
    break. Id.; see also 
    Cal. Lab. Code § 512
    (a) (imposing these
    same meal break rules for all employees unless otherwise
    exempted).
    The California Wage Order also entitles transportation
    industry employees to 10-minute rest breaks for every four
    hours worked throughout the day. 
    Cal. Code Regs. tit. 8, § 11090
    (12)(A). These rest breaks “insofar as practicable
    shall be in the middle of each work period.” 
    Id.
     California’s
    Labor Commissioner can grant an employer an exemption
    from the rest break requirement if it “would not materially
    affect the welfare or comfort of employees and would work
    an undue hardship on the employer.” 
    Id.
     § 11090(17).
    Under California law, an employer who fails to provide
    a meal or rest break must “pay the employee one additional
    hour of pay at the employee’s regular rate of compensation
    for each workday that the meal or rest or recovery period is
    not provided.” 
    Cal. Lab. Code § 226.7
    (c); see also 
    Cal. Code Regs. tit. 8, § 11090
    (11)(D), (12)(B). Employees can
    bring a claim seeking such payment under California’s
    Private Attorneys General Act of 2004 (PAGA), 
    Cal. Lab. Code §§ 2698
    –2699.6. See 
    Cal. Lab. Code § 2699.3
    .
    Employees can also seek civil penalties on behalf of
    themselves and other employees; the State receives a portion
    of any award.

     § 2699.
    C
    In response to a petition from a group of motor carriers,
    the FMCSA in 2008 declined to preempt California’s MRB
    rules as applied to commercial motor vehicle drivers subject
    to FMCSA’s hours-of-service regulations. See Petition for
    Preemption of California Regulations on Meal Breaks and
    Rest Breaks for Commercial Motor Vehicle Drivers;
    14                       IBT V. FMCSA
    Rejection for Failure to Meet Threshold Requirement,
    
    73 Fed. Reg. 79,204
    , 79,204–06 (Dec. 24, 2008). The
    FMCSA ruled that it lacked the authority to preempt because
    the MRB rules applied far beyond the trucking industry and
    were thus not “on commercial motor vehicle safety.” 
    Id. at 79
    ,205–06.
    In 2018, two industry groups, the American Trucking
    Association and the Specialized Carriers and Rigging
    Association, asked the FMCSA to revisit its 2008 “no
    preemption” determination. After seeking public comment
    on the preemption question, see California Meal and Rest
    Break Rules, 
    83 Fed. Reg. 50,142
     (Oct. 4, 2018), the
    FMCSA declared California’s MRB rules preempted as
    applied to operators of property-carrying motor vehicles
    subject to the federal hours-of-service regulations. 3 See
    California’s Meal and Rest Break Rules for Commercial
    Motor Vehicle Drivers, 
    83 Fed. Reg. 67,470
     (Dec. 28, 2018).
    The FMCSA determined that the MRB rules were in fact “on
    commercial motor vehicle safety” and could not be enforced
    under 
    49 U.S.C. § 31141
    (c). 
    83 Fed. Reg. 67,472
    –80.
    California’s Labor Commissioner and three other sets of
    petitioners (labor organizations and affected individuals)
    filed timely petitions for review.        See 
    49 U.S.C. § 31141
    (f)(1). We have jurisdiction to review these
    consolidated petitions under 
    49 U.S.C. § 31141
    (f)(2).
    Although the petitioners place different weight on different
    points, for ease of reference we generally refer to them
    collectively as “petitioners.”

    The preemption determination does not apply to drivers of
    passenger-carrying commercial motor vehicles. 83 Fed. Reg. at 67,470

    We review the FMCSA’s preemption determination
    under the Administrative Procedure Act (APA) framework
    for judicial review. The question is therefore whether the
    FMCSA’s preemption decision was “arbitrary, capricious,
    an abuse of discretion, or otherwise not in accordance with
    law,” or “in excess of statutory jurisdiction, authority, or
    limitations, or short of statutory right.”        
    5 U.S.C. § 706
    (2)(A), (C). Petitioners argue both that the FMCSA
    lacks the statutory authority to preempt the MRB rules, and,
    to the extent it could do so, that the agency’s preemption
    decision was arbitrary and capricious. Based on our careful
    review of the FMCSA’s decision and after applying the
    deference that is due the agency, we conclude that
    petitioners’ challenges lack merit.
    A
    The FMCSA only has authority to review for preemption
    State laws and regulations “on commercial motor vehicle
    safety.” 
    49 U.S.C. § 31141
    (c). The initial question we must
    address is the meaning of this phrase.
    In its preemption determination, the FMCSA concluded
    that a State law or regulation is “on commercial motor
    vehicle safety” if it “imposes requirements in an area of
    regulation that is already addressed by a regulation
    promulgated under [section] 31136.’” 83 Fed. Reg.
    at 67,473. Under this interpretation, the MRB rules are “on
    commercial motor vehicle safety” because federal
    regulations promulgated under section 31136 govern breaks
    for commercial motor vehicle drivers. Id.
    The petitioners argue that laws “on commercial motor
    vehicle safety” are those specifically directed at commercial
    16                    IBT V. FMCSA
    motor vehicle safety. They maintain that the MRB rules do
    not qualify because they apply to many workers other than
    truck drivers and regulate employee health and wellbeing
    generally. The FMCSA counters that at the very least, the
    statute is ambiguous and that the agency’s interpretation
    merits deference under Chevron, U.S.A., Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
     (1984).
    We reject, at the outset, petitioners’ arguments that
    Chevron deference is inapplicable. An agency usually
    receives Chevron deference in its construction of an
    ambiguous statute that it administers. See FDA v. Brown &
    Williamson Tobacco Corp., 
    529 U.S. 120
    , 159 (2000).
    Relying mainly on Wyeth v. Levine, 
    555 U.S. 555
     (2009),
    petitioners argue that the FMCSA is entitled to no deference
    when it comes to preemption determinations. But Wyeth
    does not apply here.
    In Wyeth, the Supreme Court declined to defer to the
    FDA’s preemption decision because “Congress ha[d] not
    authorized the FDA to pre-empt state law directly.”
    
    555 U.S. at 576
    . That is not the case here because Congress
    in 
    49 U.S.C. § 31141
    (a) expressly gave the agency authority
    to preempt “State law[s] and regulation[s] on commercial
    motor vehicle safety” when the agency “decides” certain
    criteria are met. Because the agency’s power to preempt is
    part of the overall power Congress expressly delegated to it,
    Wyeth does not diminish the deference due the agency’s
    interpretation of a statute it is charged with administering.
    See Wyeth, 
    555 U.S. at
    576–77 (explaining that “agencies
    have no special authority to pronounce on pre-emption
    absent delegation by Congress” (emphasis added)); 
    id.
    at 576 & n.9 (contrasting the FDA’s lack of express
    preemptive power with statutes that gave agencies the power
    to preempt state laws); Durnford v. MusclePharm Corp.,
    IBT V. FMCSA                         17
    
    907 F.3d 595
    , 601 n.6 (9th Cir. 2018) (agencies do not
    receive Chevron deference in interpreting a preemption
    provision “[i]n the absence of a specific congressional
    delegation of authority to interpret the scope of
    preemption”); see also City of Arlington v. FCC, 
    569 U.S. 290
    , 297 (2013) (rejecting “[t]he misconception that there
    are, for Chevron purposes, separate ‘jurisdictional’
    questions on which no deference is due”).
    The petitioners also argue that the FMCSA should
    receive no deference because the 2018 preemption
    determination reversed the agency’s 2008 determination that
    it lacked the power to preempt California’s MRB rules. But
    we have explained that “[a]n initial agency interpretation is
    not instantly carved in stone” because “the agency . . . must
    consider varying interpretations and the wisdom of its policy
    on a continuing basis.” Resident Councils of Wash. v.
    Leavitt, 
    500 F.3d 1025
    , 1036 (9th Cir. 2007) (quoting
    Chevron, 
    467 U.S. at
    863–64). As a result, “an agency’s
    ‘new’ position is entitled to deference ‘so long as the agency
    acknowledges and explains the departure from its prior
    views.’” 
    Id.
     (quoting Seldovia Native Ass’n v. Lujan,
    
    904 F.2d 1335
    , 1346 (9th Cir. 1990)); see also Nat’l Cable
    & Telecomms. Ass’n v. Brand X Internet Servs., 
    545 U.S. 967
    , 981, 1001 (2005) (explaining that an agency “is free
    within the limits of reasoned interpretation to change course
    if it adequately justifies the change” and that “[a]gency
    inconsistency is not a basis for declining to analyze the
    agency’s interpretation under the Chevron framework”);
    Rust v. Sullivan, 
    500 U.S. 173
    , 186 (1991) (explaining that
    the Supreme Court “has rejected the argument that an
    agency’s interpretation is not entitled to deference because it
    represents a sharp break with prior interpretations of the
    statute in question” (quotations omitted)).
    18                    IBT V. FMCSA
    These principles of administrative law recognize that
    democratic processes, improved understandings, or changed
    circumstances may prompt agencies to alter their own views
    over time. Petitioners have not articulated how a rule that
    precludes deference anytime an agency changes its mind
    could be justified under the basic delegation theory
    animating Chevron. See Smiley v. Citibank (S.D.), N.A.,
    
    517 U.S. 735
    , 742 (1996) (“[C]hange is not invalidating,
    since the whole point of Chevron is to leave the discretion
    provided by the ambiguities of a statute with the
    implementing agency.”). Nor have petitioners explained
    why the agency would be required to hew to a statutory
    interpretation that it no longer believes is correct. See Good
    Samaritan Hosp. v. Shalala, 
    508 U.S. 402
    , 417 (1993) (“The
    Secretary is not estopped from changing a view she believes
    to have been grounded upon a mistaken legal
    interpretation.”).
    In this case, the FMCSA acknowledged that it was
    departing from its 2008 interpretation of § 31141 and
    provided a reasoned analysis for why it was doing so. See
    Resident Councils of Wash., 
    500 F.3d at 1036
    . The FMCSA
    explained that its earlier 2008 interpretation “was
    unnecessarily restrictive” because “[t]here is nothing in the
    statutory language or legislative history that supports” its
    prior decision limiting the preemption provision to State
    laws specifically directed at commercial motor vehicle
    safety. 83 Fed. Reg. at 67,473. The FMCSA also explained
    how circumstances had changed since 2008, because the
    agency in 2011 had enacted specific break regulations for
    commercial motor vehicle drivers. Id. at 67,474. These are
    the types of explanations that an agency can offer to ensure
    that Chevron deference is applied to its new interpretation.
    See, e.g., Brand X Internet Servs., 
    545 U.S. at 981, 1001
    .
    IBT V. FMCSA                         19
    Turning to Chevron’s familiar two-step framework, we
    first ask whether the statutory text is unambiguous. “If the
    intent of Congress is clear, that is the end of the matter; for
    the court, as well as the agency, must give effect to the
    unambiguously expressed intent of Congress.” Chevron,
    
    467 U.S. at
    842–43. But if the statute is ambiguous, “the
    question for the court is whether the agency’s answer is
    based on a permissible construction of the statute.” 
    Id. at 843
    . Here, even assuming petitioners have identified a
    potential ambiguity in the statute, we hold that the agency’s
    reading is a permissible one.
    Once again, the operative statutory language is the
    phrase “on commercial motor vehicle safety.” 
    49 U.S.C. § 31141
    (a), (c). The FMCSA reasonably determined that a
    State law “on commercial motor vehicle safety” is one that
    “imposes requirements in an area of regulation that is
    already addressed by a regulation promulgated under
    [section] 31136.” 83 Fed. Reg. at 67,473. Section 31136(a)
    allows the FMCSA to issue regulations “on commercial
    motor vehicle safety.” Given the parallel language used in
    sections 31136(a) and 31141(a), when the agency has issued
    a regulation under its section 31136(a) authority, it is
    reasonable for the agency to interpret section 31141(a)
    analogously to allow preemption of State regulation in that
    same area.
    The FMCSA’s 2018 preemption decision also
    reasonably relied on Congress’s stated interest in uniformity
    of regulation. See 83 Fed. Reg. at 67,473 (explaining that
    the 1984 Act “clearly expresses Congress’s intent that ‘there
    be as much uniformity as practicable whenever a Federal
    standard and a State requirement cover the same subject
    matter’”) (quoting S. Rep. No. 98-424, at 14 (1984)); see
    also Motor Carrier Safety Act of 1984 § 203(2), 98 Stat. at
    20                    IBT V. FMCSA
    2832 (originally codified at 49 U.S.C. app. 2502) (finding
    safety benefits from “improved, more uniform commercial
    motor vehicle safety measures”). The FMCSA could
    reasonably conclude that a State law disrupts regulatory
    uniformity even when the law was not specifically directed
    at commercial vehicle motor safety because a broader State
    law could still cover the same subject matter as FMCSA
    regulations.
    Petitioners argue that the word “on” must be read
    narrowly, so that the FMCSA can only preempt State laws
    “specifically directed” at commercial motor vehicle safety.
    Petitioners thus maintain that the MRB rules cannot be “on
    commercial motor vehicle safety” because they also regulate
    working conditions and ensure employee health and
    wellbeing. But that the MRB rules may serve these other
    purposes cannot insulate them from preemption when, as
    here, the rules also promote commercial motor vehicle
    safety. See, e.g., 83 Fed. Reg. at 67,474 (“[I]n her comments
    on this petition, the California Labor Commissioner
    acknowledged that the MRB Rules improve driver and
    public safety stating, ‘It is beyond doubt that California’s
    meal and rest period requirements promote driver and public
    safety.’”).
    Nor does the fact that California regulates meal and rest
    breaks in a variety of industries compel the conclusion that
    the MRB rules are not “on commercial motor vehicle
    safety.” If California had specifically regulated the meal and
    break times of commercial motor vehicle drivers and no one
    else, that would of course be a regulation “on” commercial
    motor vehicle safety. But those drivers remain subject to the
    same regulations when California also applies its break laws
    to other types of workers. Because California’s MRB rules
    apply to drivers whose breaks are the subject of federal
    IBT V. FMCSA                           21
    regulation “on commercial motor vehicle safety,” the MRB
    rules can be described as laws “on” commercial motor
    vehicle safety as well. Or at least the FMCSA could
    permissibly conclude that was so. See Brand X Internet
    Servs., 
    545 U.S. at 989
     (“[W]here a statute’s plain terms
    admit of two or more reasonable ordinary usages, the
    [agency’s] choice of one of them is entitled to deference.”).
    Petitioners nevertheless suggest that the word “on” is
    inherently narrow and at least narrower than the phrase
    “pertaining to,” which was the Motor Carrier Safety Act’s
    original language. See §§ 206–08, 98 Stat. at 2832–37. But
    we conclude that the statute does not unambiguously require
    petitioners’ reading. See Chevron, 
    467 U.S. at
    842–43. The
    word “on” is not inevitably as narrow as petitioners claim.
    See On, prep., Oxford English Dictionary (2d ed. 1989)
    (“22. a. In regard to, in reference to, with respect to, as to.”),
    https://www.oed.com/oed2/00163302.
    The history of the 1994 revision also counsels against
    petitioners’ more confined reading. Congress changed
    “pertaining to” to “on” or “related to” in several provisions
    in a 1994 recodification. See Pub. L. No. 103-272, sec. 1(d),
    § 31141(a)–(c), 
    108 Stat. 745
    , 1008–09 (1994). But
    Congress made clear that these changes “may not be
    construed as making a substantive change in the laws
    replaced.” 
    Id.
     sec. 6(a), 108 Stat. at 1378. And “no changes
    in law or policy are to be presumed from changes of
    language” in a statutory recodification “unless an intent to
    make such changes is clearly expressed.” Finley v. United
    States, 
    490 U.S. 545
    , 554 (1989) (quotations omitted),
    superseded by statute on other grounds, as recognized in
    Exxon Mobil Corp. v. Allapattah Servs., Inc., 
    545 U.S. 546
    (2005). Given the circumstances of the 1994 amendments
    and the ambiguity that otherwise exists between “on” and
    22                    IBT V. FMCSA
    “pertaining to,” petitioners have not shown that the 1994
    recodification compels their preferred interpretation of the
    statutory text.
    Given the language in the statute, the FMCSA could
    reasonably reject petitioners’ charge that its reading of “on”
    would give the FMCSA unlimited power to preempt any law
    that merely “affects” commercial motor vehicle safety in
    some tangential way. 83 Fed. Reg. at 67,473. Petitioners
    argue, for example, that the agency’s reading of “on” would
    allow the FMCSA to preempt state laws allowing for
    pregnancy disability leave or leave to serve on a jury. These
    concerns, however, are overstated. The agency has not
    ushered in an era of unbounded FMCSA authority through
    its interpretation of the preposition “on.”
    The agency’s interpretation is more circumscribed than
    petitioners suggest: MRB rules are regulations “on
    commercial motor vehicle safety” because they are within
    FMCSA’s specific regulatory domain and the subject of
    existing federal regulation in the very same area. The
    agency has issued particularized regulations that govern
    break times for drivers of property-carrying commercial
    motor vehicles, and there is no dispute those are regulations
    “on commercial motor vehicle safety.” There is thus no
    reason to believe that the agency’s reading of “on” would
    allow it to issue regulations and preempt State laws in areas
    outside its delegated authority. Indeed, the agency expressly
    disclaims that power. See 83 Fed. Reg. at 67,473 (“This
    determination does not rely on a broad interpretation of
    section 31141 as applicable to any State law that ‘affects’
    [commercial motor vehicle] safety.”). The FMCSA’s
    interpretation of “on” does not lead to such far-reaching
    authority, either. While petitioners stress that the MRB rules
    apply across many industries, the FMCSA has not
    IBT V. FMCSA                          23
    preempted those state laws generally, but only as applied to
    drivers of property-carrying commercial motor vehicles
    subject to federal regulation.
    Nor is the FMCSA’s interpretation rendered
    unreasonable in the face of a claimed presumption against
    preemption. The Supreme Court has instructed that the
    “inquiry into the scope of a [federal] statute’s pre-emptive
    effect is guided by the rule that the purpose of Congress is
    the ultimate touchstone in every pre-emption case.” Hughes
    v. Talen Energy Mktg., LLC, 
    136 S. Ct. 1288
    , 1297 (2016)
    (alteration in original) (quoting Altria Grp., Inc. v. Good,
    
    555 U.S. 70
    , 76 (2008)). When, as here, “the statute
    ‘contains an express pre-emption clause,’ we do not invoke
    any presumption against pre-emption but instead ‘focus on
    the plain wording of the clause, which necessarily contains
    the best evidence of Congress’ pre-emptive intent.’” Puerto
    Rico v. Franklin Cal. Tax-Free Tr., 
    136 S. Ct. 1938
    , 1946
    (2016) (quoting Chamber of Com. of U.S. v. Whiting,
    
    563 U.S. 582
    , 594 (2011)); see also Atay v. County of Maui,
    
    842 F.3d 688
    , 699 (9th Cir. 2016) (same).
    Petitioners maintain that the MRB rules are part of
    California’s traditional “police power” and that a
    presumption against preemption should therefore still apply.
    But a state’s traditional regulation in an area is not, standing
    alone, sufficient to defeat preemption in the face of an
    express preemption clause. As we have explained in the
    context of the MRB rules in particular, “[w]age and hour
    laws constitute areas of traditional state regulation, although
    that fact alone does not ‘immunize’ state employment laws
    from preemption if Congress in fact contemplated their
    preemption.” Dilts v. Penske Logistics, LLC, 
    769 F.3d 637
    ,
    643 (9th Cir. 2014). In this case, the issue is not the general
    preemptive force of 
    49 U.S.C. § 31141
    (a), but the agency’s
    24                     IBT V. FMCSA
    decision to exercise its express statutory preemptive powers.
    Petitioners have not explained how a case-dispositive
    presumption against preemption could override an agency’s
    textually permissible interpretation of an express preemption
    provision it is charged with administering.
    Finally, our decision in Dilts, 
    769 F.3d 637
    , does not
    foreclose the FMCSA’s interpretation. Dilts concerned the
    scope of an express preemption provision in the Federal
    Aviation Administration Authorization Act of 1994
    (FAAAA) that prohibits state laws that are “related to”
    prices, routes, or services of commercial motor vehicles.
    
    49 U.S.C. § 14501
    (c)(1). Although Dilts held that this
    provision did not preempt California’s MRB rules, see
    769 F.3d at 647–50, we did not interpret the preemption
    provision at issue here. Dilts therefore did not address
    whether the MRB rules could fall within section 31141’s
    scope. Indeed, the plaintiffs in Dilts worked exclusively in
    California as short-haul drivers and were thus not even
    “covered by . . . federal hours-of-service regulations.” Id. at
    648 n.2.
    Similarly, although the United States filed an amicus
    brief in Dilts adhering to its 2008 determination that the
    MRB rules were not preempted under 
    49 U.S.C. § 31141
    ,
    the government also noted that the agency had “broad
    discretion” in interpreting that statute. See Brief for the
    United States as Amicus Curiae, Dilts, 
    769 F.3d 637
     (No.
    12-55705), 
    2014 WL 809150
    , at *26–27. The Dilts amicus
    brief did not maintain that the FMCSA’s 2008 interpretation
    was unambiguously compelled. Instead, it insisted the
    interpretation deserved Chevron deference. 
    Id.
     Thus,
    neither our decision in Dilts nor the United States’ position
    in that case creates an impediment to the FMCSA’s current
    preemption determination.
    IBT V. FMCSA                         25
    We therefore hold that the FMCSA permissibly
    determined that California’s MRB rules were State
    regulations “on commercial motor vehicle safety,” so that
    they were within the agency’s preemption authority.
    
    49 U.S.C. § 31141
    (a).
    B
    The FMCSA next was required to determine whether the
    MRB rules were “less stringent than,” had the “same effect”
    as, or were “additional to or more stringent than” the federal
    regulations. 
    49 U.S.C. § 31141
    (c)(1). The FMCSA found
    the third option correct. See 83 Fed. Reg. at 67,474–75.
    Petitioners argue this determination was arbitrary and
    capricious. Our review is “highly deferential, presuming the
    agency action to be valid and affirming the agency action if
    a reasonable basis exists for its decision.” Nat’l Mining
    Ass’n v. Zinke, 
    877 F.3d 845
    , 866 (9th Cir. 2017) (quotations
    omitted). We hold that the FMCSA’s determination on this
    point was reasonable and supported.
    The FMCSA concluded that the MRB rules were
    “additional to or more stringent than” federal regulations
    because California requires more breaks, more often, and
    with less flexibility as to timing. 83 Fed. Reg. at 67,474–75.
    Federal regulations generally require that a driver working
    more than eight hours must take a 30-minute break during
    the first eight hours, while providing flexibility as to when
    the break takes place. See 
    49 C.F.R. § 395.3
    (a)(3)(ii). By
    contrast, California generally requires a 30-minute meal
    break within the first five hours of work, another 30-minute
    meal break over the next five hours, and additional 10-
    minute rest periods every four hours. 
    Cal. Lab. Code § 512
    (a); 
    Cal. Code Regs. tit. 8, § 11090
    (11)(A)–(B), (12).
    The 10-minute rest breaks “insofar as practicable shall be in
    the middle of each work period.” Cal. Code Regs. tit. 8,
    26                     IBT V. FMCSA
    § 11090(12). The differences between California and
    federal law thus support the agency’s determination that the
    MRB rules impose requirements “additional to or more
    stringent than” federal law. 
    49 U.S.C. § 31141
    (c)(1)(C).
    Indeed, California acknowledges that its rules result in
    “more time off[] during the workday.”
    Petitioners make two main arguments in response. First,
    petitioners argue that California law has some flexibility in
    its design. For example, employees may agree to waive
    certain meal breaks. 
    Cal. Lab. Code § 512
    (a); 
    Cal. Code Regs. tit. 8, § 11090
    (11)(A)–(B). Employers can also seek
    exemptions from the rest break requirements from
    California’s Labor Commissioner. 
    Cal. Code Regs. tit. 8, § 11090
    (17). And the California Supreme Court has noted
    that rest breaks may take place at a time other than the
    middle of the work period “where practical considerations
    render [that] infeasible.” Brinker Rest. Corp., 
    273 P.3d at 530
    .
    Nonetheless, as compared to the federal regulations, the
    California rules still require more breaks, with greater
    frequency, and with lesser ability to adjust the break time.
    See 83 Fed. Reg. at 67,474–75. The degree of flexibility that
    California law affords thus does not undermine the agency’s
    conclusion that California’s MRB rules are still “additional
    to or more stringent than” federal requirements.
    Second, petitioners point out that, rather than provide the
    meal or rest breaks, an employer can “pay the employee one
    additional hour of pay at the employee’s regular rate of
    compensation for each workday that the meal or rest or
    recovery period is not provided.” 
    Cal. Lab. Code § 226.7
    (c);
    
    Cal. Code Regs. tit. 8, § 11090
    (11)(D), (12)(B). Petitioners
    thus argue that California law does not really impose
    additional or more stringent requirements than federal law
    IBT V. FMCSA                         27
    because an employer may simply pay to avoid complying
    with the MRB rules. It is not apparent how petitioners’
    characterization changes the analysis because employers
    under California law would still either need to provide
    breaks or make break-related payments that federal law does
    not require. See 83 Fed. Reg. at 67,475 n.9. Regardless, the
    agency’s decision was consistent with California law.
    As the FMCSA noted, California treats its MRB rules as
    requirements, providing that employers “shall not” deny the
    required breaks while creating a monetary remedy for their
    “fail[ure]” to do so. 
    Cal. Lab. Code § 226.7
    (b), (c); see also
    83 Fed. Reg. at 67,475. As California acknowledged at oral
    argument, an employer’s failure to provide the required
    breaks is also a misdemeanor under California law. See 
    Cal. Lab. Code § 1199
    ; Ward v. United Airlines, Inc., 
    466 P.3d 309
    , 315 (Cal. 2020) (noting that California Labor Code
    § 1199(c) “mak[es] violation of an IWC wage order a
    misdemeanor”). Although California represents that these
    misdemeanor prosecutions have rarely, if ever, occurred, the
    apparent availability of this remedy underscores that failure
    to comply with the break requirements is a legal violation.
    And that is how the California Supreme Court has treated
    them, in a series of decisions on which the FMCSA relied.
    In Kirby v. Immoos Fire Protection, Inc., 
    274 P.3d 1160
    (Cal. 2012), that court explained that “Section 226.7 is not
    aimed at protecting or providing employees’ wages. Instead,
    the statute is primarily concerned with ensuring the health
    and welfare of employees by requiring that employers
    provide meal and rest periods as mandated by the IWC.” 
    Id. at 1167
    . As a result, “the legal violation is nonprovision of
    meal or rest breaks.” 
    Id. at 1168
    . The court was clear:
    “section 226.7 does not give employers a lawful choice
    between providing either meal and rest breaks or an
    28                      IBT V. FMCSA
    additional hour of pay” because “[t]he failure to provide
    required meal and rest breaks is what triggers a violation of
    section 226.7.” 
    Id. at 1168
    .
    Petitioners cite Augustus v. ABM Security Services, Inc.,
    
    385 P.3d 823
     (Cal. 2016), and Murphy v. Kenneth Cole
    Productions, Inc., 
    155 P.3d 284
     (Cal. 2007). But neither
    case suggests that the FMCSA’s decision was arbitrary or
    capricious. In Augustus, the California Supreme Court noted
    that if employers “find it especially burdensome to relieve
    their employees of all duties during rest periods,” they have
    the “option[]” to “pay the premium pay set forth in . . .
    section 226.7.” 385 P.3d at 834. But Augustus cautioned
    that the payment option does not “impl[y] that employers
    may pervasively interrupt scheduled rest periods, for any
    conceivable reason—or no reason at all.” Id. at 834 n.14.
    And Augustus clarified that payments instead of breaks
    “should be the exception rather than the rule, to be used
    when the employer—because of irregular or unexpected
    circumstances such as emergencies—has to summon an
    employee back to work.” Id.
    Murphy likewise does not undermine the FMCSA’s
    reasoning. In Murphy, a pre-Kirby decision, the California
    Supreme Court held that claims for additional wages for
    violating the MRB rules were governed by the statute of
    limitations period for wage claims, not the shorter
    limitations period for penalties. 155 P.3d at 297. But this
    does not change the overall characterization of the MRB
    rules as requiring meal and rest breaks, so that failing to
    provide them is a “legal violation.” Kirby, 274 P.3d at 1167.
    As Kirby explained in reconciling Murphy, “[t]o say that a
    section 226.7 remedy is a wage . . . is not to say that the legal
    violation triggering the remedy is nonpayment of wages.”
    Id. at 1168. The FMCSA in its preemption determination
    IBT V. FMCSA                         29
    addressed petitioners’ reliance on Murphy and explained
    how (per the California Supreme Court) Murphy was
    consistent with Kirby. 83 Fed. Reg. at 67,475. That
    reasoning was not arbitrary or capricious.
    In short, the FMCSA faithfully interpreted California
    law in finding that California’s rules were “additional to or
    more stringent than” federal regulations. 
    49 U.S.C. § 31141
    (c)(1)(C).
    C
    At this point in its analysis, the FMCSA could preempt
    the MRB rules as applied to drivers of property-carrying
    commercial vehicles if it decided that the State law (1) “has
    no safety benefit” or (2) “is incompatible with the regulation
    prescribed by the Secretary,” or (3) that “enforcement of the
    State law or regulation would cause an unreasonable burden
    on interstate commerce.” 
    Id.
     § 31141(c)(4)(A)–(C). The
    agency found all three criteria met. 83 Fed. Reg. at 67,475–
    80. Petitioners argue that each finding was arbitrary and
    capricious.
    Any one of the three enumerated grounds is enough to
    justify a preemption determination.           See 
    49 U.S.C. § 31141
    (c)(4). We do not address the agency’s first two
    findings because we hold that the agency did not act
    arbitrarily or capriciously in finding that enforcement of the
    MRB rules “would cause an unreasonable burden on
    interstate commerce.” 
    Id.
     § 31141(c)(4)(C).
    In reaching that conclusion, the FMCSA found that the
    MRB rules “impose significant and substantial costs
    stemming from decreased productivity and administrative
    burden.” 83 Fed. Reg. at 67,479. The administrative record
    supports these conclusions. As to decreased productivity,
    30                     IBT V. FMCSA
    the FMCSA could reasonably determine that the MRB rules
    cause an unreasonable burden on interstate commerce
    because they “decrease each driver’s available duty hours.”
    Id. The FMCSA examined the federal and California
    schemes and explained how the MRB rules required drivers
    to spend more time on breaks. See, e.g., id. at 67,478 & n.12.
    The FMCSA also relied on public comments
    demonstrating how the MRB rules’ more demanding break
    requirements affected productivity and, in turn, the efficient
    operation of an interstate delivery system. Id. at 67,479. For
    example, FedEx Corporation explained that “to take off-duty
    breaks, the ‘drivers must slow down, exit the roadway, find
    a safe and suitable location to park and secure their vehicles,
    and then exit the vehicle’ and that the company has to build
    additional time, up to 90 minutes, into the drivers’ routes.”
    Id. Other public comments and studies showed the financial
    impact of the lost productivity and its effect on distribution
    systems. Id. These costs were exacerbated by “California’s
    share of the national economy” and the fact that
    “California’s three major container ports carry
    approximately 50% of the nation’s total container cargo
    volume.”      Id. at 67,478–79.       The evidence in the
    administrative record thus supports the FMCSA’s
    determination that lost driving time leads to lost productivity
    and burdens interstate commerce.
    The FMCSA also reasonably relied on “the
    administrative burden associated with complying with the
    MRB rules.” Id. at 67,479. This burden included higher
    compliance costs, increases in administrative and operations
    headcount, changes to delivery and logistics programs,
    revision of routes, and changes to compensation plans. Id.
    The agency also properly considered “the effect on interstate
    commerce of implementation of [the MRB rules] with the
    IBT V. FMCSA                         31
    implementation of all similar laws and regulations of other
    States.” 
    49 U.S.C. § 31141
    (c)(5). The FMCSA noted that
    twenty States had their own meal and rest break rules, and
    this “patchwork of requirements,” increased the burden on
    interstate commerce. 83 Fed. Reg. at 67,479–80. Among
    other things, companies had to create “elaborate schedules”
    to navigate the different State requirements. Id. Taken
    together, all these findings support the agency’s
    determination that the MRB rules “cause an unreasonable
    burden on interstate commerce.” 49 U.S.C. 31141(c)(4)(C).
    Petitioners’ counterarguments do not show that the
    agency acted arbitrarily or capriciously. Contrary to
    petitioners’ assertion, the agency did weigh costs and
    benefits in concluding that the MRB rules posed an
    unreasonable burden on interstate commerce. The FMCSA
    “acknowledge[d] that the State of California has a legitimate
    interest in promoting driver and public safety.” 83 Fed. Reg.
    at 67,479. It explained, however, that “the Federal [hour of
    service] rules and the provisions in the [federal motor carrier
    safety regulations] relating to fatigued driving and employer
    coercion serve to promote that interest.” Id. Properly
    understood, the FMCSA simply determined that, in its view,
    federal regulations adequately and more appropriately
    balanced the competing interests between safety and
    economic burden. Id.; see also id. at 67,476 (explaining how
    federal regulations “balanc[e] the need to prevent excessive
    hours of continuous driving with a driver’s need for
    flexibility in scheduling a rest break”). Petitioners have not
    shown that conclusion was unreasonable. Nor was the
    FMCSA required to conduct its preemption assessment in a
    manner identical to a dormant Commerce Clause undue
    32                         IBT V. FMCSA
    burden analysis. See Pike v. Bruce Church, Inc., 
    397 U.S. 137
     (1970). 4
    We likewise reject petitioners’ assertion that the
    FMCSA’s cumulative burden analysis was flawed because
    industry must already comply with varying State laws in
    other areas, such as environmental and anti-discrimination
    laws. In petitioners’ view, the “marginal cost” of complying
    with “one more set” of varying State laws is “negligible.”
    But this argument does not show that the FMCSA’s
    preemption determination, made under a statute which gives
    it the express authority to do so, was arbitrary or capricious.
    As the FMCSA noted, many of the state laws that
    petitioners cite “are well outside the scope of the Agency’s
    statutory authority.” 83 Fed. Reg. at 67,480. And because
    motor carriers will always be subject to varying state laws to
    some extent, petitioners’ argument, if accepted, would
    significantly limit the FMCSA’s ability to determine that
    divergent state laws “on commercial motor vehicle safety”
    pose an unreasonable burden on interstate commerce.
    Nothing in the statute suggests the agency’s preemptive
    powers are so constrained. Indeed, the statute is directly to
    the contrary: it allows the agency to consider the cumulative
    “effect on interstate commerce of implementation” of the
    state law in question “with the implementation of all similar
    laws and regulations of other States.”             
    49 U.S.C. § 31141
    (c)(5). In any event, the FMCSA here had more than
    4
    One petitioner argues that the FMCSA did not consider the non-
    safety benefits of the MRB rules, such as workplace dignity or higher
    wages for drivers. But there is no indication that the statute requires the
    FMCSA to consider such factors, which are likely outside its expertise.
    IBT V. FMCSA                              33
    sufficient basis to conclude that the MRB rules burden
    interstate commerce in a way that is not merely “negligible.”
    Finally, petitioners err in claiming that two of our
    decisions    invalidate     the     FMCSA’s     preemption
    determination. They do not. In Sullivan v. Oracle Corp.,
    
    662 F.3d 1265
     (9th Cir. 2011), we held that California’s
    overtime rules did not violate the dormant Commerce Clause
    because “California applies its Labor Code equally to work
    performed in California, whether that work is performed by
    California residents or by out-of-state residents.” 
    Id. at 1271
    . That holding has no apparent relevance to this case.
    Nor did we resolve the cumulative burden question as a
    matter of law when we stated in Dilts that “applying
    California’s meal and rest break laws to motor carriers
    would not contribute to an impermissible ‘patchwork’ of
    state-specific laws, defeating Congress’ deregulatory
    objectives.” 769 F.3d at 647. As we have noted, Dilts did
    not concern the statute at issue here. And the above
    statement turned on Dilts’ determination that the meal and
    rest break laws were not “related to” prices, routes, and
    services under the FAAAA’s preemption provision. Id.
    Like Sullivan, Dilts does not foreclose the agency’s
    preemption determination. 5
    5
    IBT Local 2785 briefly argues that the FMCSA also flouted
    numerous statutes and executive orders, but fails to explain how the
    agency violated these various laws. We do not address these arguments,
    as IBT Local 2785 “failed to argue” these issues “with any specificity in
    [its] briefing.” Carmickle v. Comm’r, Soc. Sec. Admin., 
    533 F.3d 1155
    ,
    1161 n.2 (9th Cir. 2008).
    Petitioners Ly and Morgan also ask us to review an FMCSA legal
    memorandum issued months after the preemption determination. In that

    *     *    *
    We appreciate petitioners’ arguments in favor of their
    preferred approach to governance in the area of commercial
    motor vehicle safety. But in this case, petitioners’ objections
    are ultimately as much to the statute Congress drafted as they
    are to the FMCSA’s preemption determination. Under the
    principles that govern our evaluation of the agency’s
    decision, the petitions for review must be
    DENIED.
    memorandum, an FMCSA lawyer opined that the agency’s preemption
    decision applied retroactively. This determination was not part of the
    preemption determination on review, see 
    49 U.S.C. § 31141
    (f), nor was
    it final agency action, see 
    5 U.S.C. § 704
    . We thus do not consider the
    retroactivity issue.
    Finally, pro se intervenor William Trescott asks the court to vacate
    various federal regulations. These issues are also not part of the
    FMCSA’s preemption determination and are thus not before us.
    
    49 U.S.C. § 31141
    (f). Trescott’s motion to expedite the appeal is
    DENIED as moot.
