    State of Nebraska, appellee, v.
    Seidy N. Albarenga, appellant.
    ___ N.W.2d ___
    Filed December 23, 2022.   No. S-21-213.
    1. Ordinances: Appeal and Error. Interpretation of a municipal ordi-
    nance is a question of law, on which an appellate court reaches an inde-
    pendent conclusion irrespective of the determination made by the court
    below.
    2. Statutes: Appeal and Error. The interpretation of statutes and regu-
    lations presents questions of law which an appellate court reviews
    de novo.
    3. Constitutional Law: Search and Seizure: Motions to Suppress:
    Appeal and Error. When reviewing a trial court’s ruling on a motion
    to suppress based on a claimed violation of the Fourth Amendment, an
    appellate court applies a two-part standard of review. Regarding histori-
    cal facts, an appellate court reviews the trial court’s findings for clear
    error, but whether those facts trigger or violate Fourth Amendment
    protections is a question of law that an appellate court reviews indepen-
    dently of the trial court’s determination.
    4. Statutes: Ordinances. State preemption arises with respect to munici-
    pal ordinances or township laws and flows from the principle that
    municipal legislation is invalid if it is repugnant to, or inconsistent with,
    state law.
    5. ____: ____. Preemption of municipal ordinances by state law is based
    on the fundamental principle that municipal ordinances are inferior in
    status and subordinate to the laws of the state.
    6. Constitutional Law: Municipal Corporations: Statutes: Ordinances.
    Where a municipality has constitutionally conferred powers to form a
    charter and enact ordinances, the state law is the superior law only as to
    matters of statewide concern.
    7. Highways. Highway control, which includes traffic control of city
    streets, is a preeminently state affair that affects the whole state.

    8. Highways: Legislature. Traffic control of city streets is a legislative
    function in the exercise of its inherent police power to provide the
    means and methods of alleviating, in the public interest, traffic con-
    gestion throughout the state, particularly that which is designated as
    through traffic.
    9. Highways. It is of statewide concern that traffic lanes through congested
    areas be kept open and that such areas be not permitted to operate as
    a bottleneck in the free movement of traffic, and this transcends any
    purely local concern.
    10. Statutes. There are three types of preemption: (1) express preemption,
    (2) field preemption, and (3) conflict preemption.
    11. Statutes: Legislature: Intent. The touchstone of preemption analysis is
    legislative intent.
    12. Statutes: Legislature: Ordinances. 
    Neb. Rev. Stat. § 60-6
    ,108(3)
    (Reissue 2021) expressly preempts local laws to the extent those laws
    are directly contrary to the Nebraska Rules of the Road, unless expressly
    authorized by the Legislature.
    13. Highways. A steady red indication under 
    Neb. Rev. Stat. § 60-6
    ,123(3)(c)
    (Reissue 2021) includes lighted arrows.
    14. Statutes: Legislature: Intent. In discerning the meaning of a statute,
    a court must determine and give effect to the purpose and intent of the
    Legislature as ascertained from the entire language of the statute con-
    sidered in its plain, ordinary, and popular sense, it being a court’s duty
    to discover, if possible, the Legislature’s intent from the language of the
    statute itself.
    15. Statutes. A court must give effect to all parts of a statute, and if it can
    be avoided, no word, clause, or sentence will be rejected as superfluous
    or meaningless.
    16. ____. A statute is ambiguous when the language used cannot be ade-
    quately understood either from the plain meaning of the statute or when
    considered in pari materia with any related statutes.
    17. ____. The in pari materia doctrine is an intrinsic aid whereby a court
    regards all statutes upon the same general subject matter as part of one
    system, and later statutes as supplementary or complementary to those
    preceding them.
    18. Statutes: Legislature: Intent. Absent an express intent to incorporate
    another legislative body’s law, the in pari materia doctrine does not
    apply as between laws enacted by different legislative bodies at differ-
    ent times.
    19. Administrative Law: Statutes: Legislature. The Legislature can del-
    egate to an administrative agency the power to make rules and regula-
    tions to implement the policy of a statute, but the administrative agency
    - 74 -

    is limited in its rulemaking authority to the powers delegated to it by
    the statute which it is to administer.
    20.   Administrative Law: Statutes. In order to be valid, a rule or regulation
    must be consistent with the statute under which the rule or regulation is
    promulgated.
    21.   ____: ____. An administrative agency may not employ its rulemaking
    power to modify, alter, or enlarge portions of its enabling statute.
    22.   Administrative Law: Statutes: Appeal and Error. While appellate
    courts have traditionally given considerable weight to a department’s
    construction of an ambiguous statute it is charged with enforcing, resort
    to contemporaneous construction of a statute by administrative bodies
    is neither necessary nor proper where the language used is clear, or its
    meaning can be ascertained by the use of intrinsic aids alone.
    23.   Highways: Words and Phrases. For purposes of 
    Neb. Rev. Stat. § 60-6
    ,123(3)(c) (Reissue 2021), the term “traffic control device” is
    defined by § 60-123 and is a physical object; a traffic control device
    does not refer to an ordinance or the meaning attributed to that object
    vis-a-vis a local ordinance.
    24.   Search and Seizure: Evidence. The exclusionary rule is not found
    in the federal or state Constitution, but is a prudential doctrine to
    be employed where the deterrence benefits of suppression outweigh
    its costs.
    25.   Police Officers and Sheriffs: Probable Cause. Police officers are not
    required to be legal scholars, but implicit in the probable cause standard
    is the requirement that a police officer’s mistakes be reasonable.
    26.   Police Officers and Sheriffs: Presumptions. Law enforcement is
    charged with enforcing laws, which are presumptively valid unless and
    until they are declared invalid.

    INTRODUCTION
    We granted further review of a Nebraska Court of Appeals’
    decision affirming the defendant’s convictions for violating a
    municipal traffic signal law and for driving under the influence
    (DUI). The issues presented are (1) whether 
    Neb. Rev. Stat. § 60-6
    ,123(3)(c) (Reissue 2021) preempts a city ordinance
    providing that vehicular traffic facing a steady red arrow at the
    intersection of two one-way streets is prohibited from turning
    left at any time while the arrow remains red and (2) whether
    the evidence derived from the stop should have been excluded
    because the officer could not reasonably rely on a preempted
    traffic ordinance in making the stop. We reverse the traffic
    ordinance conviction but affirm the DUI conviction.
    BACKGROUND
    Following a stipulated trial, Seidy N. Albarenga was found
    guilty in county court of DUI, first offense, and of violating
    an automatic traffic signal, both in violation of municipal ordi-
    nances of the city of Lincoln, Nebraska. She was sentenced
    accordingly.
    Traffic Stop
    Albarenga’s convictions stem from a traffic stop that took
    place in Lincoln on June 28, 2019. A law enforcement officer
    observed Albarenga on 17th Street, facing north, in the west-
    ernmost lane at the intersection with Q Street. Both 17th and Q
    Streets are one way, with Q Street running west.
    The westernmost lane of 17th Street faced a traffic signal
    that displayed green, yellow, and red arrow lights. The only
    sign accompanying the signal was one directing traffic to turn
    left only. A similar arrow signal in at least one other intersec-
    tion in Lincoln is accompanied by a separate sign indicating
    there is no turn on a red arrow.

    Albarenga came to a complete stop at the intersection. The
    traffic control device displayed a red arrow light. After stop-
    ping, and while the red arrow was still lit, Albarenga turned
    left onto Q Street.
    The law enforcement officer initiated a traffic stop on
    the grounds that Albarenga “violated the left turn arrow.”
    During the stop, the officer observed signs that Albarenga was
    impaired. A chemical test showed a reading of 0.142 of a gram
    of alcohol per 210 liters of breath.
    Charges
    Albarenga was charged with two counts in county court.
    Count 1 charged her with DUI, first offense, in violation of
    Lincoln Mun. Code § 10.16.030 (2017). Count 2 charged
    her with violating an automatic traffic signal, in violation of
    Lincoln Mun. Code § 10.12.030 (2017). Section 10.12.030
    prohibits turning at a steady red arrow indication and requires
    the driver to remain stopped until a green light is displayed.
    It states:
    Whenever traffic is controlled by an automatic traffic
    signal or other official traffic control device exhibiting
    different colored lights or colored, lighted arrows succes-
    sively, one at a time or in combination, only the colors
    green, red, and yellow shall be used, except for pedestrian
    signals, and said lights shall indicate and apply to drivers
    of vehicles and pedestrians as follows:
    ....
    RED ARROW: Vehicular traffic facing a lighted steady
    red arrow shall stop before entering the crosswalk on the
    near side of the intersection and remain stopped until a
    green light is displayed, except as otherwise permitted in
    this title.
    Pretrial Motions
    Albarenga moved to quash count 2 and moved to suppress
    the evidence derived from the stop, which the State intended to
    offer to prove the charges in count 1. Both motions revolved

    around Albarenga’s argument that what § 10.12.030 directs
    a steady red arrow light shall signal to drivers in Lincoln is
    in direct conflict with what § 60-6,123(3)(c) directs a steady
    red arrow light shall signal to drivers throughout the State of
    Nebraska. She argued that § 60-6,123 requires any “steady
    red indication,” which specifically includes “different colored
    lights or colored lighted arrows,” “shall indicate” to drivers
    at an intersection of two one-way streets that they “may cau-
    tiously enter the intersection to make a left turn after stop-
    ping.” Thus, Albarenga argued that § 10.12.030 prohibits what
    § 60-6,123 expressly permits and that § 10.12.030 is thereby
    preempted by state law.
    Section 60-6,123 is part of the Nebraska Rules of the Road
    (Rules of the Road). 1 Describing traffic signals, § 60-6,123
    provides in relevant part:
    Whenever traffic is controlled by traffic control sig-
    nals exhibiting different colored lights or colored lighted
    arrows, successively one at a time or in combination, only
    the colors green, red, and yellow shall be used, except for
    special pedestrian signals carrying a word legend, num-
    ber, or symbol, and such lights shall indicate and apply to
    drivers of vehicles and pedestrians as follows:
    (1)(a) Vehicular traffic facing a circular green indica-
    tion may proceed straight through or turn right or left
    unless a sign at such place prohibits either such turn,
    but vehicular traffic, including vehicles turning right or
    left, shall yield the right-of-way to other vehicles and to
    pedestrians lawfully within the intersection or an adjacent
    crosswalk at the time such indication is exhibited;
    (b) Vehicular traffic facing a green arrow indication,
    shown alone or in combination with another indica-
    tion, may cautiously enter the intersection only to make
    the movement indicated by such arrow or such other

    movement as is permitted by other indications shown at
    the same time, and such vehicular traffic shall yield the
    right-of-way to pedestrians lawfully within an adjacent
    crosswalk and to other traffic lawfully using the intersec-
    tion; and
    (c) Unless otherwise directed by a pedestrian-control
    signal, pedestrians facing any green indication, except
    when the sole green indication is a turn arrow, may pro-
    ceed across the roadway within any marked or unmarked
    crosswalk;
    (2)(a) Vehicular traffic facing a steady yellow indica-
    tion is thereby warned that the related green movement is
    being terminated or that a red indication will be exhibited
    immediately thereafter when vehicular traffic shall not
    enter the intersection, and upon display of a steady yellow
    indication, vehicular traffic shall stop before entering the
    nearest crosswalk at the intersection, but if such stop can-
    not be made in safety, a vehicle may be driven cautiously
    through the intersection; and
    (b) Pedestrians facing a steady yellow indication,
    unless otherwise directed by a pedestrian-control signal,
    are thereby advised that there is insufficient time to cross
    the roadway before a red indication is shown and no
    pedestrian shall then start to cross the roadway;
    (3)(a) Vehicular traffic facing a steady red indication
    alone shall stop at a clearly marked stop line or shall stop,
    if there is no such line, before entering the crosswalk on
    the near side of the intersection or, if there is no cross-
    walk, before entering the intersection. The traffic shall
    remain standing until an indication to proceed is shown
    except as provided in subdivisions (3)(b) and (3)(c) of
    this section;
    (b) Except where a traffic control device is in place
    prohibiting a turn, vehicular traffic facing a steady red
    indication may cautiously enter the intersection to make a
    right turn after stopping as required by subdivision (3)(a)

    of this section. Such vehicular traffic shall yield the right-
    of-way to pedestrians lawfully within an adjacent cross-
    walk and to other traffic lawfully using the intersection;
    (c) Except where a traffic control device is in place
    prohibiting a turn, vehicular traffic facing a steady red
    indication at the intersection of two one-way streets may
    cautiously enter the intersection to make a left turn after
    stopping as required by subdivision (3)(a) of this sec-
    tion. Such vehicular traffic shall yield the right-of-way to
    pedestrians lawfully within an adjacent crosswalk and to
    other traffic lawfully using the intersection; and
    (d) Unless otherwise directed by a pedestrian-control
    signal, pedestrians facing a steady red indication alone
    shall not enter the roadway.
    The county court ruled that § 10.12.030 was not preempted
    by state law and overruled Albarenga’s pretrial motions.
    Appeal to District Court
    Albarenga appealed to the district court, assigning as error
    the county court’s rulings on her pretrial motions. The district
    court affirmed her convictions. The district court agreed with
    the county court that § 10.12.030 did not conflict with the
    Rules of the Road.
    Court of Appeals
    Albarenga thereafter appealed to the Court of Appeals,
    asserting that the district court erred in affirming the county
    court’s rulings denying her motions to quash and to suppress.
    Albarenga assigned that the district court erred by affirming
    the county court’s (1) finding that § 10.12.030 is not in conflict
    with § 60-6,123, (2) denial of Albarenga’s motion to suppress,
    and (3) denial of Albarenga’s motion to quash count 2. The
    Court of Appeals also affirmed the convictions. 2
    The Court of Appeals found merit to Albarenga’s reading
    of § 60-6,123 in isolation, noting that § 60-6,123, by referring

    in its introductory clause to “both ‘colored lights’ and ‘colored
    lighted arrows’” as encompassed therein, demonstrated an
    awareness of both circular and arrow indications. 3 Observing
    that what a statute does not say is as important as what it does,
    the Court of Appeals concluded that by setting forth in other
    subsections separate rules for “‘a circular green indication’”
    versus “‘a green arrow indication,’” while giving only one
    rule for “‘a steady red indication,’” without distinguishing
    between a circle and an arrow, § 60-6,123 refers by the term
    “steady red indication” in § 60-6,123(3)(c) to both a red arrow
    and a red circle. 4
    Nevertheless, the Court of Appeals concluded § 60-6,123
    should be read in pari materia with the Manual on Uniform
    Traffic Control Devices (Manual), which was adopted pursuant
    to § 60-6,118, and of which the Court of Appeals took judicial
    notice. 5 Under the Manual, a steady red arrow signal prohibits
    entering the intersection unless a traffic control device is in
    place permitting a turn on a steady red arrow. The Court of
    Appeals observed that “§ 4D.04, ¶ 3, items C.1 & C.2,” of the
    Manual provided as follows:
    “C. Steady red signal indications shall have the follow-
    ing meanings:
    “1. Vehicular traffic facing a steady CIRCULAR
    RED signal indication, unless entering the intersection
    to make another movement permitted by another signal
    indication, shall stop . . . and shall remain stopped until
    a signal indication to proceed is displayed, or as pro-
    vided below.
    “Except when a traffic control device is in place pro-
    hibiting a turn on red or a steady RED ARROW signal
    indication is displayed, vehicular traffic facing a steady
    CIRCULAR RED signal indication is permitted to enter

    the intersection to turn right, or to turn left from a one-
    way street into a one-way street, after stopping. . . .
    “2. Vehicular traffic facing a steady RED ARROW
    signal indication shall not enter the intersection to make
    the movement indicated by the arrow and, unless enter­ing
    the intersection to make another movement permit­ted by
    another signal indication, shall stop . . . and shall remain
    stopped until a signal indication or other traffic control
    device permitting the movement indicated by such RED
    ARROW is displayed.
    “When a traffic control device is in place permitting
    a turn on a steady RED ARROW indication, vehicular
    traffic facing a steady RED ARROW signal indication
    is permitted to enter the intersection to make the move-
    ment indicated by the arrow signal indication, after
    stopping.” 6
    The Court of Appeals noted the Manual provided further, that
    “‘[e]xcept as described in Item C.2 in Paragraph 3 of Section
    4D.04, turning on a steady RED ARROW signal indi­cation
    shall not be permitted.’” 7
    The Court of Appeals did not expressly analyze whether
    the provisions of the Manual it quoted were consistent with
    the provisions of the Rules of the Road and the mandate
    of the enabling statute, § 60-6,118, that the Department of
    Transportation may adopt and promulgate rules and regula-
    tions and implement a manual providing a uniform system
    of traffic control devices “[c]onsistent with the provisions of
    the . . . Rules of the Road.” Nor did it discuss whether prin-
    ciples of in pari materia apply as between statutes and regula-
    tions. The Court of Appeals cited the proposition that agency
    regulations properly adopted and filed with the Secretary of
    State of Nebraska have the effect of statutory law and bind

    the agency that promulgated them just as they bind indi-
    vidual citizens. 8 It then reasoned that the Manual is more
    specific than § 60-6,123 concerning red arrow indications and
    therefore controlling.
    We granted Albarenga’s petition for further review.
    ASSIGNMENTS OF ERROR
    In her brief in support of further review, Albarenga assigns
    that the Court of Appeals erred by (1) taking judicial notice of
    the Manual, (2) finding that the plain language of the Manual
    should be treated like a statute, (3) treating the Manual as
    the “‘controlling law’” when it found that the statutory lan-
    guage of § 60-6,123 was “‘less specific”’ than the language
    of the Manual, (4) finding that § 10.12.030 is consistent with
    Nebraska law, and (5) finding that her second and third assign-
    ments of error were without merit “‘because there is no con-
    flict between § 10.12.030 and § 60-6,123.’”
    STANDARD OF REVIEW
    [1] Interpretation of a municipal ordinance is a question of
    law, on which we reach an independent conclusion irrespective
    of the determination made by the court below. 9
    [2] The interpretation of statutes and regulations presents
    questions of law which we review de novo. 10
    [3] When reviewing a trial court’s ruling on a motion to sup-
    press based on a claimed violation of the Fourth Amendment,
    an appellate court applies a two-part standard of review. 11
    Regarding historical facts, an appellate court reviews the trial
    court’s findings for clear error, but whether those facts trig-
    ger or violate Fourth Amendment protections is a question of

    law that an appellate court reviews independently of the trial
    court’s determination. 12
    ANALYSIS
    Albarenga asserts on appeal, as she did below, that
    § 10.12.030 is in conflict with § 60-6,123(3)(c) and thereby
    preempted by state law. She asserts that because § 10.12.030
    is preempted, the county court erred in denying her motion
    to quash the charge against her in count 2 for violating
    § 10.12.030 and the Court of Appeals erred in affirming her
    conviction of violating that ordinance. Albarenga argues it also
    follows from the preemption of § 10.12.030 that the stop for
    violating § 10.12.030 was not objectively reasonable and that
    the district court should have granted her motion to suppress
    the evidence derived from the stop.
    The State does not agree that § 10.12.030 is preempted
    by § 60-6,123(3)(c), but argues that, even if it is, the arrest-
    ing officer reasonably relied on the ordinance when stopping
    Albarenga for a traffic violation. The State accordingly argues
    that the district court did not err in overruling Albarenga’s
    motion to suppress and that the DUI conviction, at the very
    least, should be affirmed.
    We agree with Albarenga that § 10.12.030 is preempted by
    state law. We also agree with the State that the arresting officer
    reasonably relied on the ordinance when making the stop.
    Preemption
    [4-6] State preemption arises with respect to municipal
    ordinances or township laws and flows from the principle
    that municipal legislation is invalid if it is repugnant to, or
    inconsistent with, state law. 13 Preemption of municipal ordi-
    nances by state law is based on the fundamental principle that

    municipal ordinances are inferior in status and subordinate to
    the laws of the state. 14 That said, where a municipality such as
    Lincoln has constitutionally conferred powers to form a char-
    ter and enact ordinances, the state law is the superior law only
    as to matters of statewide concern. 15
    [7-9] Highway control, which includes traffic control of
    city streets, is a preeminently state affair that affects the whole
    state. 16 We have explained that traffic control of city streets
    is a legislative function in the exercise of its inherent police
    power to provide the means and methods of alleviating, in the
    public interest, traffic congestion throughout the state, “par-
    ticularly that which is designated as through traffic.” 17 “It is of
    state-wide concern that traffic lanes through congested areas
    be kept open and that such areas be not permitted to operate as
    a bottleneck in the free movement of traffic,” and this “tran-
    scends any purely local concern.” 18
    [10,11] There are three types of preemption: (1) express pre-
    emption, (2) field preemption, and (3) conflict preemption, 19
    although it has been commented in the federal preemption
    context that the three categories “are anything but analytically
    air-tight.” 20 In all three cases, the touchstone of preemption
    analysis is legislative intent. 21

    One of the express purposes of the Rules of the Road, set
    forth in § 60-602(7), is “[t]o assist traffic law enforcement by
    encouraging voluntary compliance with law through uniform
    rules.” Accordingly, § 60-604 sets forth rules of construction
    of the Rules of the Road that they “shall be so interpreted
    and construed as to effectuate their general purpose to make
    uniform the laws relating to motor vehicles.” Section 60-680
    authorizes local authorities within the reasonable exercise of
    their police power to “regulate” traffic by means of traffic
    control devices and “[r]egulate or prohibit” stopping and the
    turning of vehicles, but this provision does not authorize, in
    the course of so doing, the adoption of ordinances in direct
    conflict with the Rules of the Road.
    [12] Section 60-6,108(3) explicitly mandates that no local
    authority shall enact or enforce any ordinance directly con-
    trary to the Rules of the Road:
    The Nebraska Rules of the Road shall be applicable and
    uniform throughout this state and in all political sub-
    divisions and municipalities of this state, and no local
    authority shall enact or enforce any ordinance directly
    contrary to the Nebraska Rules of the Road unless
    expressly authorized by the Legislature.
    We explained in Butler County Dairy v. Butler County 22 that
    in expressly preempting local laws, the Legislature includes
    provisions explicitly stating in some manner that (1) the
    legislation preempts local laws related to the subject matter
    of the legislation, (2) a certain subject is governed solely by
    the legislation, or (3) political subdivisions are prohibited
    from enacting any local law conflicting with the legislation.
    Section 60-6,108(3) explicitly preempts local laws to the
    extent those law are directly contrary to the Rules of Road,
    unless expressly authorized by the Legislature.
    [13] Section 60-6,123 of the Rules of the Road plainly
    provides: “Except where a traffic control device is in place

    pro­hibiting a turn,” a steady red arrow signal “shall indi-
    cate . . . to drivers” they are permitted to “cautiously enter
    the intersection to make a left turn after stopping.” While
    § 60-6,123(3)(c) does not expressly refer to the shape of the
    signal, subsection (3)(c) refers broadly to a “steady red indica-
    tion” and, under the introductory clause of § 60-6,123, pro-
    vides that “[w]henever traffic is controlled by traffic control
    signals exhibiting different colored lights or colored lighted
    arrows,” “such lights shall indicate and apply to drivers of
    vehicles and pedestrians” as described by its subsections. In
    other words, reading § 60-6,123(3)(c) in light of all parts
    of the statute, a “steady red indication” includes “lighted
    arrows.” We cannot read out of “steady red indication” the
    general inclusion of arrows in the “traffic control signal” the
    statute is meant to describe.
    Thus, it is not a fair reading of the “steady red indication”
    referenced in § 60-6,123(3)(c) that it includes circular lights but
    excludes arrow lights. And we note that throughout § 60-6,123,
    the Legislature utilized the terms “circular green indication,”
    “green arrow indication,” “steady yellow indication,” “red
    indication,” and “steady red indication,” while nowhere differ-
    entiating between a “steady red indication” that is circular and
    one that is an arrow. The Legislature expressly differentiated
    between green circles and arrows, but not for red indications.
    We cannot read into the statute a distinction between arrows
    and circles that deliberately is not there.
    [14-16] In discerning the meaning of a statute, we must
    determine and give effect to the purpose and intent of the
    Legislature as ascertained from the entire language of the
    statute considered in its plain, ordinary, and popular sense,
    it being our duty to discover, if possible, the Legislature’s
    intent from the language of the statute itself. 23 A court must
    give effect to all parts of a statute, and if it can be avoided,

    no word, clause, or sentence will be rejected as superfluous or
    meaningless. 24 A statute is ambiguous when the language used
    cannot be adequately understood either from the plain mean-
    ing of the statute or when considered in pari materia with any
    related statutes. 25
    Giving effect to all words and parts of § 60-6,123, it is not
    ambiguous. It plainly provides that the “steady red indica-
    tion,” a subset of “traffic control signals exhibiting different
    colored light or colored lighted arrows,” encompasses “col-
    ored lighted arrows.” Such “traffic control signals” “shall
    . . . apply to drivers of vehicles” in this state so as to indi-
    cate at the intersection of two one-way streets that they “may
    cautiously enter the intersection to make a left turn after
    stopping.”
    [17,18] The Manual cannot be utilized in pari materia
    with § 60-6,123 to create ambiguity in the statute where
    there is none. Contrary to what the Court of Appeals sug-
    gested in its opinion, rules and regulations are not at the
    same level with statutes for the purpose of an in pari materia
    reading of a statutory scheme. The in pari materia doctrine
    is an intrinsic aid whereby we “regard all statutes upon the
    same general subject matter as part of one system, and later
    statutes . . . as supplementary or complementary to those
    preceding them.” 26 We look to that which has been enacted
    by the same legislative body to discern that body’s uniform
    design, presuming the legislative body is conscious of its
    own prior enactments. 27 We have applied this in pari materia

    doctrine as between statutes, as between regulations, 28 and as
    between ordinances, 29 but we have not applied in pari materia
    principles vertically between these differing legislative bod-
    ies. The U.S. Supreme Court has explained that the in pari
    materia doctrine’s application makes the most sense when
    the statutes were enacted by the same legislative body at the
    same time, but it can also apply to laws enacted by the same
    legislative body at different times, albeit with lesser force. 30
    Absent an express intent to incorporate another legislative
    body’s law, 31 the in pari materia doctrine does not apply as
    between laws enacted by different legislative bodies at dif-
    ferent times.
    [19-22] The Legislature can delegate to an administrative
    agency the power to make rules and regulations to implement
    the policy of a statute, 32 but the administrative agency is limited
    in its rulemaking authority to the powers delegated to it by
    the statute which it is to administer. 33 In order to be valid, a
    rule or regulation must be consistent with the statute under
    which the rule or regulation is promulgated. 34 An administra-
    tive agency may not employ its rulemaking power to modify,
    alter, or enlarge portions of its enabling statute. 35 While we
    have traditionally given considerable weight to a depart-
    ment’s construction of an ambiguous statute it is charged

    with enforcing, resort to contemporaneous construction of a
    statute by administrative bodies is neither necessary nor proper
    where the language used is clear, or its meaning can be ascer-
    tained by the use of intrinsic aids alone. 36 Section 60-6,123 is
    not ambiguous. Therefore, the Manual has no bearing on our
    understanding of the statute.
    The State argues that even if a “steady red indication”
    plainly encompasses red arrows and mandates, as a default,
    that a cautious turn after stopping is permitted at a steady red
    arrow signal, the Lincoln ordinance—or the steady red arrow,
    by virtue of the ordinance—is a “traffic control device . . . in
    place prohibiting a turn.” Again, § 60-6,123(3)(c) provides:
    “Except where a traffic control device is in place prohibiting a
    turn, vehicular traffic facing a steady red indication at the inter-
    section of two one-way streets may cautiously enter the inter-
    section to make a left turn after stopping . . . .” We disagree
    with the State’s understanding of a “traffic control device.”
    [23] The State overlooks that “traffic control device” is
    defined in § 60-670 as “any sign, signal, marking, or other
    device not inconsistent with the Nebraska Rules of the Road
    placed or erected by authority of a public body or official hav-
    ing jurisdiction for the purpose of regulating, warning, or guid-
    ing traffic.” Section 10.12.030, as already discussed, is incon-
    sistent with § 60-6,123(3)(c) of the Rules of the Road, and thus,
    it would not satisfy § 60-670 for that reason. Additionally, the
    reference in § 60-670 to the device being “placed or erected,”
    along with the statutory reference in § 60-6,123(3)(c) to the
    “traffic control device” being “in place,” and a similar refer-
    ence in § 60-670 to a “[t]raffic control device” being “placed
    or erected,” refers to a physical object rather than a meaning
    attributed to that object vis-a-vis a local ordinance.
    A uniform meaning of a steady red arrow indication, as set
    forth by the Rules of the Road, is necessary for the State to
    achieve the objectives of encouraging the free movement of

    traffic. Nothing in the language of the statutory scheme, nor
    in logic, suggests that by providing an exception for a “traffic
    control device . . . prohibiting a turn,” the Legislature wished
    to confer upon each municipality across this state the abil-
    ity to establish by ordinance different meanings for the same
    steady red arrow indication explicitly defined by the Rules
    of the Road. Doing so would create confusion and impede
    traffic flow and would be directly contrary to the stated pur-
    pose in § 60-604 of “mak[ing] uniform the laws relating to
    motor vehicles.”
    By prohibiting a turn on a steady red arrow indication after
    stopping, § 10.12.030 runs directly counter to the provision
    of § 60-6,123(3)(c) that permits a turn on a steady red arrow
    indication after stopping. The ordinance attempts to forbid that
    which the Legislature has expressly authorized. Accordingly,
    § 10.12.030 is preempted by state law.
    The Court of Appeals erred by failing to reverse the
    decisions of the lower courts with respect to the denial of
    Albarenga’s motion to quash the charge in count 2. The ordi-
    nance Albarenga was charged with violating under that count is
    unenforceable because it is preempted by state law. We find it
    unnecessary to address Albarenga’s assignment that the Court
    of Appeals erred in taking judicial notice of the Manual.
    Exclusionary Rule
    It does not necessarily follow from our holding invalidating
    § 10.12.030 that the fruits of the stop supporting Albarenga’s
    DUI conviction were inadmissible. Albarenga argues the
    Lincoln police officers have a duty to know the Rules of the
    Road and should have known the ordinance was preempted.
    While law enforcement officers have a duty to know the law,
    § 10.12.030 was the law at the time of the stop, and we find
    that a reasonable officer would not have anticipated our hold-
    ing that § 10.12.030 is preempted by § 60-6,123(3)(c).

    houses, papers, and effects, against unreasonable searches
    and seizures . . . ,” as does article I, § 7, of the Nebraska
    Constitution. 37 The exclusionary rule is not found in the fed-
    eral or state Constitution, but is a prudential doctrine to be
    employed where the deterrence benefits of suppression out-
    weigh its costs. 38 When the police exhibit deliberate, reckless,
    or grossly negligent disregard for Fourth Amendment rights,
    the deterrent value of exclusion is strong and tends to out-
    weigh the resulting costs. 39 On the other hand, when the police
    act with an objectively reasonable good faith belief that their
    conduct is lawful or when their conduct involves only simple,
    isolated negligence, the deterrent value is weak and tends not
    to outweigh the resulting costs. 40
    [25] As a general matter, the decision to stop an automo-
    bile is reasonable where the police have probable cause to
    believe that a traffic violation has occurred. 41 In reviewing a
    challenge to the legality of an automobile stop, the question
    is not whether the police officer issued a citation for a traffic
    violation or whether the State ultimately proved the violation;
    instead, a stop of a vehicle is objectively reasonable when
    the police officer has probable cause to believe that a traffic
    violation has occurred. 42 Police officers are not required to
    be legal scholars, 43 but implicit in the probable cause stan-
    dard is the requirement that a police officer’s mistakes be
    reasonable. 44

    [26] Under most circumstances, it is unreasonable to expect
    an officer to question the validity of the law the officer is
    charged with enforcing. 45 Law enforcement is charged with
    enforcing laws, which are presumptively valid unless and until
    they are declared invalid. 46 With few possible exceptions, such
    as where a law is “so grossly and flagrantly unconstitutional
    that any person of reasonable prudence would be bound to see
    its flaws,” “[s]ociety would be ill-served” if its law enforce-
    ment officers took it upon themselves to determine which laws
    are and which are not entitled to enforcement. 47
    People v. McNeil 48 illustrates a criminal ordinance that was
    held not to be presumptively valid because well-established
    case law had declared as preempted by state law an ordinance
    substantively similar to the one under which the defendant had
    been arrested and searched incident to arrest. 49 The court held
    the precedent so undermined the continuing enforceability of
    the ordinance that it was not objectively reasonable for the
    officers to rely upon it. 50 In contrast, at the time of the stop of
    Albarenga for turning on a steady red arrow signal, there was
    no case law indicating § 10.12.030, or any similar ordinance,
    was preempted. The Court of Appeals’ decision and the lower
    courts’ conclusions in this case illustrate this fact.
    It was objectively reasonable for the officer who stopped
    Albarenga to presume that § 10.12.030 was enforceable,
    and there is no dispute that the officer observed Albarenga’s

    failing to comply with § 10.12.030. The county court did
    not err in denying Albarenga’s motion to suppress, and the
    Court of Appeals, albeit on different grounds, did not err in
    so holding.
    CONCLUSION
    For the foregoing reasons, we reverse the Court of Appeals’
    decision with respect to Albarenga’s conviction on count 2 for
    violating § 10.12.030 and remand the cause to the Court of
    Appeals with directions to reverse the judgment of the district
    court on count 2 and to direct the district court to remand the
    cause to the county court with directions to vacate the convic-
    tion on count 2 and to dismiss that charge of the complaint.
    Affirmed in part, and in part reversed
    and remanded with directions.
