    THE HONORABLE ROBERT G. BEVERLY, MEMBER OF THE CALIFORNIA
    SENATE, has requested an opinion on the following question:
    Does a California city have the authority to prohibit the
    parking of particular categories of vehicles, such as recreational
    vehicles or motor vehicles which exceed a specified length or
    width, on its residential streets during all or certain hours of
    the day?
    CONCLUSION
    A California city has no authority to prohibit the
    parking of particular categories of vehicles on its residential
    streets during all or certain hours of the day, with the exception
    of commercial vehicles having a manufacturer's gross vehicle weight
    rating of 10,000 pounds or more.
    ANALYSIS
    This opinion addresses the question of whether a
    California city may adopt an ordinance to prohibit the general
    parking of particular classes of vehicles on its residential
    streets. For example, we are asked whether a city might enact an
    ordinance to specifically prohibit the parking on residential
    streets of oversized vehicles, or the parking of recreational
    vehicles.1 We will see that the authority for a city to adopt such
    1
    The question asked does not define the term "recreational
    vehicle" and the term is not defined in the Vehicle Code. However,
    the term does have a customary meaning in the industry and among
    1.                            89-602
    an ordinance must be found in the specifics of the Vehicle Code,
    and on examining its provisions we will conclude that with the
    exception of being able to prohibit the parking of certain
    commercial vehicles in residential areas, a city is without
    authority to particularize other types of vehicles, as by size, or
    kind, or use, in order to similarly prohibit their parking.
    Section 7 of article XI of the California Constitution
    provides that a city "may make and enforce within its limits all
    local, police, sanitary, and other ordinances and regulations not
    in conflict with general laws." (Cal. Const, art. XI, § 7.) This
    authority is often referred to as the "police power" (70
    Ops.Cal.Atty.Gen. 210, 211 (1987)), and an ordinance adopted under
    it would be presumed to be valid as long as it did not conflict
    with general, i.e., state law. (Cf., Freeman v. Contra Costa
    County Water District (1971) 
    18 Cal. App. 3d 404
    , 408; Stanislaus Co.
    etc. Assn. v. Stanislaus (1937) 
    8 Cal. 2d 378
    , 383, 384.)
    But if a city ordinance adopted under the "police power"
    does conflict with state law it would be void. ( People ex rel.
    Deukmejian v. County of Mendocino (1984) 
    36 Cal. 3d 476
    , 484; 72
    Ops.Cal.Atty.Gen. 180, 182 (1989).)       Our Supreme Court has
    summarized the notion of conflict:
    "`"As defined by the cases the constitutional phrase
    `conflict with general laws' ... may arise in several
    different ways. It may grow out of the exact language of
    the state and municipal laws [citations] or from a local
    attempt `to impose additional requirements in a field
    that is preempted by general law' [citations] or from the
    state's adoption of `a general scheme for the regulation
    of a particular subject' [citations]."'" (Baron v. City
    of Los Angeles (1970) 
    2 Cal. 3d 535
    , 541 [emphasis added];
    see also People ex rel Deukmejian v. County of 
    Mendocino, supra, at 484-485
    ; Lancaster v. Municipal Court (1972) 
    6 Cal. 3d 805
    , 806, 808; 58 Ops.Cal.Atty.Gen. 519, 521-523,
    529 (1975); 58 Ops.Cal.Atty.Gen. 13, 
    14, supra
    .)
    "Conflict" with state law can thus arise in many ways,
    and as pertinent herein, one of them occurs when the state has
    enacted a comprehensive legislative scheme intended for uniform
    application throughout the state and has indicated an intention to
    preempt local regulation in the area. The Vehicle Code is such an
    enactment and in fact contains its own preemption rule, found in
    RV-users, where it normally includes vehicles which are self-
    propelled or towed and which are designed to be slept in. Thus
    "recreational vehicle" would include such vehicles as travel
    trailers, van campers, truck campers, coaches, and motorhomes,
    although taken on its face the term is broad enough to include any
    vehicle used for "recreation."
    2.                            89-602
    its section 21.2 ( Rumford v. City of Berkeley (1982) 
    31 Cal. 3d 545
    , 551; County of Los Angeles v. City of Alhambra (1980) 
    27 Cal. 3d 184
    , 189; Pipoly v. Benson (1942) 
    20 Cal. 2d 366
    , 371; City
    of Lafayette v. County of Contra Costa (1979) 
    91 Cal. App. 3d 749
    ,
    755, 756; Mervynne v. Acker (1961) 
    189 Cal. App. 2d 558
    , 561-562; 68
    Ops.Cal.Atty.Gen. 101, 102 (1985); 64 Ops.Cal.Atty.Gen. 707, 709­
    710 (1981); 55 Ops.Cal.Atty.Gen. 178, 179 (1972).) In that section
    the State has expressed its plenary power and its preemption of the
    entire field of traffic regulation and control. (Rumford v. City
    of 
    Berkeley, supra
    , [the entire field of traffic control]; City of
    Lafayette v. County of Contra Costa , supra, at 755 [the area of
    motor vehicle traffic control]; 64 Ops.Cal.Atty.Gen. 707, 
    709, supra
    [the area of motor vehicle traffic regulation and control].)
    Section 21 provides as follows:
    "Except as otherwise expressly provided, the
    provisions of this code are applicable and uniform
    throughout   the  state   and   in   all  counties   and
    municipalities therein, and no local authority shall
    enact or enforce any ordinance on the matters covered by
    this code unless expressly authorized therein."
    Thus, "a city may regulate traffic on its public streets only to
    the extent it is so expressly authorized in the Vehicle Code" (68
    Ops.Cal.Atty.Gen. 101, 
    102, supra
    ; fn. omitted), and unless it has
    been so expressly authorized, it "has no authority over vehicular
    traffic control. [Citations.]" ( Rumford v. City of 
    Berkeley, supra
    , 31 Cal.3d at 550.) What this means is that "a [c]ity does
    not have a `very wide discretion' under the police power in
    legislating in the field covered by the Vehicle Code. Instead it
    has no police power in that area at all, `unless expressly
    authorized' [therein] by the Legislature." (City of Lafayette v.
    County of Contra Costa , 
    supra, 91 Cal. App. 3d at 749
    ; emphases
    original.)
    The regulation of parking on public streets is an adjunct
    to the control and regulation of vehicular traffic, and that field
    too is now preempted by state law. (County of Los Angeles v. City
    of 
    Alhambra, supra
    , 
    27 Cal. 3d 184
    , 192-193; Siegel v. City of
    Oakland (1978) 
    79 Cal. App. 3d 351
    , 357, 358; Mervynne v. 
    Acker, supra
    , 189 Cal.App.2d at 561; Bentley v. Chapman (1952) 
    113 Cal. App. 2d 1
    , 3; 64 Ops.Cal.Atty.Gen. 707, 
    710, supra
    .)
    It was not always so. Prior to 1935, the Vehicle Code
    prohibited local authorities from enacting ordinances which in any
    2
    Further references to sections of the Vehicle Code will be by
    section number only, and unidentified section references herein
    should be understood to be to that Code unless context dictates
    otherwise.
    3.                            89-602
    way conflicted with its provisions (see e.g., Veh. Code [1919], §
    22(d); Stats. 1919, ch. 147, p. 223, § 13), but since the Code did
    not address "the method or manner of parking vehicles on the
    streets of cities or towns" (cf., Flynn v. Blesdoe Co. (1928) 
    92 Cal. App. 145
    , 152), it was held that "no conflict [was] created by
    a city ordinance regulating the same." (Ibid.) With the enactment
    of the Vehicle Code of 1935 (Stats. 1935, ch. 27, p. 93), "the
    Legislature determined to ... preempt the field of local
    legislation in the area of motor vehicle traffic control." (City
    of Lafayette v. County of Contra 
    Costa, supra
    , 91 Cal.App.3d at
    755.) Section 458 of that Code provided:
    "The provisions of this division [i.e., division 11
    entitled "Traffic Laws"] are applicable and uniform
    throughout   the  State   and   in   all   counties   and
    municipalities therein and no local authority shall enact
    or enforce any ordinance on the matters covered by this
    division unless expressly authorized herein." (Stats.
    1935, ch. 27, p. 164.)
    But an undefined authority for local authorities to enact some
    local parking regulations was found in section 472 of the Code, and
    under it it was held that "local authorities [were] ... authorized
    to enact special rules and regulations dealing with parking of
    vehicles." (Pipoly v. Benson (1942) 
    20 Cal. 2d 366
    , 373.)3
    In 1953, however, the Legislature added former section
    459.8 to the Vehicle Code to provide a specific, and as we shall
    see a limited, grant of authority for local authorities to regulate
    parking.    (Stats. 1953, ch. 709, p. 1979, § 2.)      The section
    provided:
    "The provisions of this division shall not prevent
    local authorities, by ordinance or resolution, from
    prohibiting the parking or standing of vehicles on
    certain streets or highways, or portions thereof, at all
    3
    Section 472 of the Vehicle Code of 1935 provided:
    "Curb Markings to Indicate Parking Regulations.
    Whenever   local   authorities   enact   local   parking
    regulations and indicate them by the use of paint upon
    curbs, the following colors only shall be used and such
    colors indicate as follows: [red = no stopping; yellow =
    stopping only to unload passengers or freight; white =
    stopping only for loading or unloading of passengers;
    green = time limit parking, as may be specified by local
    ordinance.] [¶]Regulations indicated as above provided
    shall be effective upon such days and during such hours
    or times as may be prescribed by local ordinance."
    (Stats. 1935, ch. 27, p. 169.)
    4.                            89-602
    or certain hours of the day."   (Stats. 1953, ch. 709, §
    
    2, supra
    .)
    The Legislature recodified the Vehicle Code in 1959, and
    upon that recodification, "preempted the entire field covered by
    [it] by substituting in place of section 458 the new section
    21...." (City of Lafayette v. County of Contra 
    Costa, supra
    , 91
    Cal.App.3d at 755.)      As quoted above, it only permits local
    authorities to enact ordinances on matters covered by the Code only
    to the extent "expressly authorized therein." (Veh. Code, § 
    21, supra
    .) Thus, to answer the question whether a city may prohibit
    certain classes of vehicles from parking on residential streets,
    under section 21 of the Vehicle Code we must look to its other
    provisions to see the extent to which the Legislature has expressly
    permitted local authorities to regulate parking. (Cf., Rumford v.
    City of 
    Berkeley, supra
    , 31 Cal.3d at 550; City of Lafayette v.
    County of Contra 
    Costa, supra
    , at 756; 67 Ops.Cal.Atty.Gen. 1, 4
    (1984).)4
    In several sections of chapter 9 (§ 22500 et seq.) of
    division 11 of the Code, the Legislature has permitted local
    authorities, such as cities, to adopt ordinances to regulate
    parking within their jurisdiction in various situations.5 Most of
    4
    It should be noted that the regulation of vehicular use of
    the public roads and highways by whatever means is outside the
    "municipal affairs" constitutional grant of authority to chartered
    cities, by which they are given power superior to that of the
    Legislature to legislate on matters of "municipal" concern.
    (Rumford v. City of 
    Berkeley, supra
    , 31 Cal.3d at 550 fn. 3; 68
    Ops.Cal.Atty.Gen. 101, 102 fn. 
    2, supra
    ; 67 Ops.Cal.Atty.Gen. 1, 
    4, supra
    ; cf., Cal.Const., art. XI, § 5; 72 Ops.Cal.Atty.Gen. 180, 182
    fn. 
    4, supra
    .) The regulation of parking is also not a "municipal
    affair" in the sense of giving a chartered municipality control of
    the matter in derogation of the power of the state. (County of Los
    Angeles v. City of 
    Alhambra, supra
    , 27 Cal.3d at 193; Siegel v.
    City of 
    Oakland, supra
    , 79 Cal.App.3d at 357; Mervynne v. 
    Acker, supra
    , 189 Cal.App.2d at 561-562, 564-565.)
    5
    A "local authority" is defined to mean "the legislative body
    of every county or municipality having authority to adopt local
    police regulations." (§ 385.) The terms "park" or "parking" are
    defined to mean "the standing of a vehicle, whether occupied or
    not, otherwise than temporarily for the purpose and while actually
    engaged in loading or unloading merchandise or passengers." (§
    463; see also, Fleming v. Flick (1934) 
    140 Cal. App. 14
    , 30 ["...the
    term park ... [means] in substance, the voluntary act of leaving a
    car on the main-traveled portion of the highway when not in use.
    It means something more than a mere temporary or momentary stoppage
    on   the   road   for   a   necessary    purpose."];   accord,   64
    Ops.Cal.Atty.Gen. 29, 34 & 34 fn. 4 (1981); 62 Ops.Cal.Atty.Gen. 4
    5.                            89-602
    the sections conferring that authority involve the adoption of
    ordinances to address specific parking situations that are not
    directly relevant because they do not involve the imposition of a
    general restriction on parking in residential areas. 6 But two of
    the sections of the chapter require analysis.
    Section 22507, which derives from the aforementioned
    section 459.8 that was added to the Vehicle Code of 1935 in 1953,
    permits local authorities to adopt ordinances to prohibit or
    otherwise restrict parking "on certain streets or highways, or
    portions thereof, during all or certain hours of the day." And
    section 22507.5 permits them to adopt ordinances prohibiting or
    restricting the parking of vehicles on certain streets or highways
    or portions thereof, between the hours of 2 a.m. and 6 a.m., and
    ordinances to "prohibit or restrict the parking or standing, on any
    street, or portion thereof, in a residential district, of
    commercial vehicles having a manufacturer's gross vehicle weight
    rating of 10,000 pounds or more."7 It is upon these sections that
    (1979).)
    6
    (See e.g., §§ 22503.5 [ordinances providing special parking
    regulations for two-wheeled or three-wheeled motor vehicles]; 22506
    [ordinances prohibiting or restricting parking of vehicles on a
    state highway within the jurisdiction]; 22507.6 [ordinances
    prohibiting or restricting parking on designated streets or
    highways for the purpose of street cleaning]; 22508 [ordinances
    establishing parking meter zones and white-lined designated parking
    spaces within which a vehicle must park]; 22509 [ordinances
    requiring the blocking of wheels when vehicles are on hills in
    business or residential districts]; 22510 [ordinances prohibiting
    parking on highways, the width of which is restricted after snow
    clearance]; 22511.7 and 22511.8 [ordinances designating special
    parking for disabled persons and disabled veterans]; 22512
    [ordinances reducing the state's 15 foot prohibited parking
    distance from a fire hydrant]; 22519 [ordinances regulating,
    prohibiting or restricting parking of vehicles in any offstreet
    parking facility which the locality owns or operates].)
    7
    A "commercial vehicle" is "a vehicle of a type required to be
    registered under the [Vehicle Code] used or maintained for the
    transportation of persons for hire, compensation, or profit or
    designated, used, or maintained primarily for the transportation of
    property.   (§ 260, subd. (a).)    It does not include a "vanpool
    vehicle." (Id., subd. (c); cf., § 668.)
    The "manufacturer's gross vehicle weight rating" is "the
    weight in pounds of the chassis of a truck or truck tractor with
    lubricants, radiator full of water, full fuel tank or tanks plus
    the weights of the cab or driver's compartment, body, special
    chassis and body equipment and pay load as authorized by the
    6.                            89-602
    a city would have to rely for authority to adopt the type of
    ordinance contemplated in the question.
    A.   Section 22507.
    We turn first to section 22507. It is the older of the
    two sections and the one which gives local agencies the most
    general authority to control parking. The section presently reads
    as follows:
    "Local authorities may, by ordinance or resolution,
    prohibit or restrict the stopping, parking, or standing
    of vehicles, including, but not limited to, vehicles
    which are six feet or more in height (including any load
    thereon) within 100 feet of any intersection, on certain
    streets or highways, or portions thereof, during all or
    certain hours of the day. The ordinance or resolution
    may include a designation of certain streets upon which
    preferential parking privileges are given to residents
    and merchants adjacent to the streets for their use and
    the use of their guests, under which the residents and
    merchants may be issued a permit or permits which exempt
    them from the prohibition or restriction of the ordinance
    or resolution. With the exception of alleys, no such
    ordinance or resolution shall apply until signs or
    markings giving adequate notice thereof have been placed.
    A local ordinance or resolution adopted pursuant to this
    section may contain provisions which are reasonable and
    necessary to ensure the effectiveness of a preferential
    parking program." (Emphasis added.)
    Section 22507 contains four parts: (i) a general grant
    of authority to permit local authorities to prohibit parking on
    certain streets and highways at all or certain hours of the day;
    (ii) the specific inclusion of an authority to permit them to
    prohibit or restrict the parking of vehicles over six feet in
    height within 100 feet of an intersection; (iii) a grant of
    authority for them to designate certain streets upon which
    preferential parking privileges would be given to residents and
    merchants; and (iv) a requirement that signs be posted to give
    notice of any parking restriction imposed under the section. We
    turn our attention to the first two of these components to
    determine whether local authorities can prohibit the parking of
    particular types of vehicles in residential areas.8 This will take
    chassis manufacturer."   (§ 390.)
    8
    It could not be successfully argued that such authority can
    be eked from the authority found in the third component of the
    section giving local authorities power to designate certain streets
    upon which preferential parking privileges are given to residents
    7.                           89-602
    us to a stepped analysis based on the chronological evolution of
    the section.
    1.   The General Authorization To Prohibit Parking.
    Section 22507 commences with a general grant for local
    authorities to
    "... prohibit or restrict the ... parking ... of
    vehicles .... on certain streets or highways, or portions
    thereof, during all or certain hours of the day."
    As mentioned, this language dates almost verbatim from a 1953
    addition to the Vehicle Code of 1935, and it was carried forward to
    section 22507 when the Vehicle Code was recodified in 1959 (Stats.
    1959, ch. 3, p. 1700, § 2). 9 To ascertain the intended scope of
    this grant we look to its wording (cf., Moyer v. Workmen's Comp.
    Appeals Bd. (1973) 
    10 Cal. 3d 222
    , 230; People v. Knowles (1950) 
    35 Cal. 2d 175
    , 182; Rich v. State Board of Optometry (1965) 
    235 Cal. App. 2d 591
    , 604), and interpret it according to the usual,
    ordinary and generally accepted meaning of the words used to frame
    it. (Cf., People v. Craft (1986) 
    41 Cal. 3d 554
    , 560; People v.
    Belleci (1979) 
    24 Cal. 3d 879
    , 884; Palos Verdes Faculty Assn. v.
    Palos Verdes Peninsula Unified Sch. Dist. (1978) 
    21 Cal. 3d 650
    ,
    658; Great Lakes Properties Inc . v. City of El Segundo (1977) 
    19 Cal. 3d 152
    , 155-156.) Reference to the dictionary is helpful to
    understand the common generally accepted meaning of a term. (Cf.,
    People v. Spencer (1975) 
    52 Cal. App. 3d 563
    , 565; People v. Medina
    (1972) 
    27 Cal. App. 3d 473
    , 479.)
    and their guests. That authority deals with "classes of persons,"
    not "classes of vehicles" and it is inappropriate to extrapolate an
    authority to restrict one from the authority to restrict the other.
    (Cf., City of Lafayette v. County of Contra 
    Costa, supra
    , 91
    Cal.App.3d at 756 fn. 2.)
    9
    As we have seen, in 1953 section 459.8 was added to the
    Vehicle Code of 1935 to provide as follows: "The provisions of
    this division shall not prevent local authorities, by ordinance or
    resolution, from prohibiting the parking or standing of vehicles on
    certain streets or highways, or portions thereof, at all or certain
    hours of the day." (Stats. 1953, ch. 709, p. 1978, § 2.) Section
    22507 of the Vehicle Code of 1959 provided: "Local authorities may
    by ordinance or resolution prohibit the parking or standing of
    vehicles on certain streets or highways, or portions thereof,
    during all or certain hours of the day. (Stats. 1959, ch. 3, p.
    1700, § 2.) In 1963 the Legislature added the words "or restrict"
    to the sentence (Stats. 1963, ch. 1070, p. 2530, § 1), and in 1987
    the word "stopping" was added. (Stats. 1987, ch. 455, p. ___, §
    4.)
    8.                            89-602
    Looking to the wording of the general grant of authority
    found in section 22507 for local authorities to regulate parking,
    we see that as added in 1953 and as it appears today, the
    Legislature used the adjective "certain" to describe both the
    places where ("streets and highways") and the times during which
    ("hours of the day") a city might prohibit or otherwise restrict
    parking but that it did not use the term when referring to the
    "vehicles" whose parking could be restricted. According to its
    usual, ordinary and generally accepted meaning, the term "certain"
    means, inter alia,
    "2a PARTICULAR: of a character ... unwise to specify
    -- used to distinguish a person or thing not otherwise
    distinguished or not distinguishable in more precise
    terms." (Webster's Third New Intn'l. Dict. (1971 ed.) at
    p. 367.)
    This would indicate that by using the term to describe the places
    where, and the times during which, a city might prohibit vehicular
    parking, the Legislature did not intend to particularize those
    places and times on a statewide basis, but intended instead to
    leave those matters to the exercise of local discretion as varying
    local needs demanded.    As such, the section would "authorize[]
    local authorities to restrict parking, at hours and places to be
    determined locally...." (Capolungo v. Bondi (1986) 
    179 Cal. App. 3d 346
    , 350.)
    In contrast, however, the Legislature did not similarly
    use the word to modify what "vehicles" could be affected by the
    exercise of that discretion. From that we believe the Legislature
    did not intend local authorities to have discretion regarding the
    kinds of vehicles covered by the ordinance.      In other words we
    believe that while the Legislature intended local authorities to
    have discretion to designate the streets and highways on which
    parking should be restricted, and the times of day during which
    such restrictions would apply, they were not to have discretion to
    designate particular types of vehicles for the purpose of applying
    parking restrictions only to them. Any parking restrictions that
    a local authority would choose to impose would have to apply to all
    vehicles or none.10
    10
    It is interesting to note that the concept of having local
    regulations affecting traffic apply to all vehicles or none finds
    expression at least as early as 1919. Subdivision (d) of section
    22 of the Vehicle Code as amended that year provided, inter alia:
    "Local authorities shall have no power to enact, enforce or
    maintain any ordinance, rule or regulation in any way in conflict
    with, contrary to or inconsistent with the provisions of this act,
    or of any section or other subdivision thereof, and no such
    ordinance, rule or regulation of said local authorities shall have
    any force or effect, excepting however, that (1) such powers as are
    now or may hereafter be vested in local authorities to enact
    9.                            89-602
    This perception of the purport of section 22507 finds
    support when we compare the treatment accorded provisions of the
    Vehicle Code where the word "certain" is present and where it is
    not.   It is present in subdivision (c) of section 21101, which
    authorizes local authorities to prohibit "the use of particular
    highways by certain vehicles...."       (Emphasis added.)    In 55
    Ops.Cal.Atty.Gen. 178 (1955) we noted that the phrase "certain
    vehicles" was not defined (id. at 182), but said that it was broad
    enough to permit a city or county to prohibit the use of particular
    highways or streets by certain classes of vehicles, such as those
    determined to be excessively noisy. (Id. at 183.) Our conclusion
    was cited in City of Lafayette v. County of Contra 
    Costa, supra
    , 
    91 Cal. App. 3d 749
    , in support of the proposition that subdivision (c)
    would permit a city to prohibit certain classes of vehicles, "such
    as trucks, or tractors, or oversize or `excessively noisy'
    vehicles, or those lacking air-inflated tires," from using
    particular highways. (Id. at 756 fn. 2.) In 67 Ops.Cal.Atty.Gen.
    
    1, supra
    , we again considered the subdivision and concluded that
    the phrase "certain vehicles" gave local agencies some limited
    authority to restrict the roads on which certain cargoes, such as
    hazardous material, might be transported in the jurisdiction. (Id.
    at 5-7.)
    In contrast to its subdivision (c), the modifier
    "certain" is absent from subdivision (a) of section 21101, which
    permits local authorities to adopt an ordinance "[c]losing any
    highway [which includes streets (§ 360)] to vehicular traffic when
    in [its opinion it] is no longer needed for vehicular traffic." In
    Rumford v. City of 
    Berkeley, supra
    , 
    31 Cal. 3d 545
    and City of
    Lafayette v. County of Contra 
    Costa, supra
    , 
    91 Cal. App. 3d 749
    , the
    courts considered the issue of whether that grant of authority
    permitted a city to partially close a public street to some traffic
    but not to other.    Each case held that subdivision (a) did not
    provide that discretion, and that a city would have to close the
    street equally to all traffic or none. (31 Cal.3d at 
    554-558; 91 Cal. App. 3d at 756-757
    .)     We reached a similar conclusion in 68
    Ops.Cal.Atty.Gen. 10
    1, supra
    , finding that the subdivision did not
    permit a city to adopt an ordinance authorizing "controlled access"
    to the public streets in a residential neighborhood. (Id. at 103.)
    By analogy to the foregoing, we find that while section
    22507's general authorization for local agencies to "prohibit or
    restrict the ... parking ... of vehicles ... on certain streets or
    highways ... during all or certain hours of the day" might accord
    ordinances and regulations, applicable equally and generally to all
    vehicles and other users of the highways, and providing for traffic
    or crossing officers or semaphores, to bring about the orderly
    passage of vehicles and other users of the public highways on
    certain portions thereof, where the traffic is heavy and
    continuous...." (Stats. 1919, ch. 147, § 13, p. 223.)
    10.                           89-602
    discretion to a city to designate certain streets or highways and
    certain hours of the day for parking restrictions to be imposed, it
    does not provide authority to prohibit or restrict the parking of
    only certain types of vehicles.
    2.   The Specific Authorization To Restrict The Parking
    of A Certain Class Of Vehicles.
    In 1984 the Legislature amended section 22507 to add in
    the just-discussed general authorization of its first sentence, a
    specific authority for local authorities to restrict the parking of
    vehicles more than six feet in height within 100 feet of an
    intersection. (Stats. 1984, ch. 181, p. 555, § 2.) As amended,
    the section then permitted local authorities to prohibit or
    restrict "the parking or standing of vehicles, including vehicles
    which are six feet or more in height (including any load thereon)
    within 100 feet of any intersection , on certain streets or
    highways, or portions thereof, during all or certain hours of the
    day." (§22507, as amended by Stats. 1984, ch. 181, § 
    2, supra
    ;
    emphasis added.)
    How was this meant to augment the existing general grant of
    authority already found in the section?
    "When determining the legislative purpose behind a
    statutory amendment, [one] may properly consider committee reports
    (Southland Mechanical Constructors Corp . v. Nixen (1981) 
    119 Cal. App. 3d 417
    , 427), partisan caucus analyses (id. at p. 428), and
    the digest of the Legislative Counsel. (People v. Superior Court
    (Douglass) 1979 
    24 Cal. 3d 428
    , 434)." (People v. Martinez (1987)
    
    194 Cal. App. 3d 15
    , 22; see also, People v. Aston (1985) 
    39 Cal. 3d 481
    , 492-493; Hittle v. Santa Barbara County Employees Retirement
    Assn. (1985) 
    39 Cal. 3d 374
    , 387; California Teachers Assn . v.
    Governing   Board    (1983)   
    141 Cal. App. 3d 606
    ,    613;   68
    Ops.Cal.Atty.Gen. 23, 25-26, fn. 3; 66 Ops.Cal.Atty.Gen. 382, 386
    (1983).) This is because it will be presumed that the Legislature
    adopted the subject legislation with the intent and meaning
    expressed in those documents. (People v. 
    Martinez, supra
    , citing
    People v. Superior Court (Douglass) , supra at 434, People v.
    Swinney (1975) 
    46 Cal. App. 3d 332
    , 342, and Maben v. Superior Court
    (1967) 
    255 Cal. App. 2d 708
    , 713.)
    From such type of documents in the legislative history of
    the Bill (AB 286) that enacted the 1984 amendment to section 22507,
    we learn that "[t]he vehicle height prohibition provisions [were]
    intended to provide better visibility at intersections."       (See
    e.g., Assembly Office Of Research, Concurrence in Senate Amendments
    To AB 286; Senate Republican Caucus, Digest To AB 286, p. 2; Senate
    Transportation Committee, Analysis Of AB 286, p. 2.) The amendment
    was thus wrought with an overall purpose of promoting one aspect of
    traffic safety. (Cf., Capolungo v. 
    Bondi, supra
    , 
    179 Cal. App. 3d 346
    , 351, 352.)
    11.                           89-602
    But why was the amendment necessary at all to achieve
    that end, when section 22507 already gave local authorities the
    authority "to prohibit or restrict the parking or standing of
    vehicles on certain streets or highways, or portions thereof, at
    all or certain hours of the day"? The Legislative Counsel's Digest
    to the Bill (AB 286) which amended the section --again, a valuable
    aid in determining the Legislature's reasons for the legislation-­
    provides the answer. The Digest states:
    "Existing law authorizes local authorities to
    prohibit or restrict the parking or standing of vehicles
    on certain streets or highways during all or certain
    hours of the day. [¶]     This bill would specifically
    include vehicles which are 6 feet or more in height
    (including any load thereon) within 100 feet of any
    intersection as vehicles whose parking or standing may be
    prohibited or restricted by local authorities ."       (4
    Stats. 1984, Sum. Dig. [AB 286], pp. 58-59; emphasis
    added.)
    We thus see that the amendment was enacted to specifically permit
    local agencies to prohibit or restrict the parking of a particular
    type of vehicle at a particular place - i.e., vehicles that are
    more than six feet in height, within 100 feet of an intersection.
    What we perceive that to mean is that without that specific
    authorization, local authorities would have been without power to
    single out such oversized vehicles in order to prohibit their
    parking within 100 feet of an intersection, despite the broad
    general language found in the introduction to section 22507. The
    Legislature obviously considered the amendment necessary in order
    to confer that authority on local agencies and permit them to
    prohibit the parking of a specific type of vehicle because the
    existing general authority to "prohibit or restrict the parking ...
    of vehicles on certain streets" did not suffice to do so. Surely
    if it already had, the Legislature's efforts to add the specific
    authorization would have produced statutory surplusage, and that is
    an interpretation of legislative efforts to be avoided. (Cf., City
    and County of San Francisco v. Farrell (1982) 
    32 Cal. 3d 47
    , 55;
    California Mfgrs. Assn. v. Public Utilities Com. (1979) 
    24 Cal. 3d 836
    , 844; Fields v. Eu (1976) 
    18 Cal. 3d 322
    , 328.)
    We are thus reinforced in our conclusion that the general
    grant of authority found in the introduction to section 22507 did
    not enable local authorities to single out particular types of
    vehicles in order to restrict their parking.
    This perception of the purport of the 1984 amendment is
    consistent with the dictate that the delegation to local agencies
    to make rules and regulations to regulate traffic is to be strictly
    construed and that any grant of such authority must be expressly
    declared by the Legislature in explicit and unmistakable terms.
    (Cf., Rumford v. City of Berkeley , 
    supra, 31 Cal. 3d at 550
    , 553;
    12.                           89-602
    City of Lafayette v. County of Contra 
    Costa, supra
    , 91 Cal.App.3d
    at 756 & 756 fn. 3; People v. Moore (1964) 
    229 Cal. App. 2d 221
    , 228;
    67 Ops.Cal.Atty.Gen. 1, 
    4, supra
    .)
    The 1984 amendment to section 22507 also demonstrates
    that when the Legislature has wanted to grant local authorities
    power to enact an ordinance to prohibit the parking of a particular
    type of vehicle for reasons of traffic safety, it knows how to do
    so and has done so specifically. That it has not done so with
    respect to other types of vehicles would indicate an intention that
    local agencies were not to have authority to similarly prohibit or
    otherwise restrict their parking. (Cf., Safer v. Superior Court
    (1975) 
    15 Cal. 3d 230
    , 236, 238; Board of Trustees v. Judge (1975)
    
    50 Cal. App. 3d 920
    , 927; see also, Wildlife Alive v. Chickering
    (1976) 
    18 Cal. 3d 190
    , 196; DeWeese v. Unick (1980) 
    102 Cal. App. 3d 100
    , 106; Rich v. State Board of Optometry (1965) 
    235 Cal. App. 2d 591
    , 607, discussing the doctrine of "expressio unius est exclusio
    alterius," i.e., the rule that the expression of one thing in a
    statute necessarily excludes other things not mentioned.)
    In 1985 the Legislature again amended section 22507 to
    add the phrase "but not limited to" after the word "including" in
    the first sentence of the section.      With that amendment local
    authorities were given their presently worded authority to
    "prohibit or restrict the parking ... of vehicles, including, but
    not limited to, vehicles which are six feet or more in height ...
    within 100 feet of any intersection, on certain streets or
    highways, or portions thereof, during all or certain hours of the
    day." (§ 22507 as amended by Stats. 1985, ch. 912, § 2. p. 2906;
    emphasis added.) With the amendment, it now became clear that the
    inclusion of the specific grant of authority to local agencies to
    prohibit or restrict the parking of vehicles over six feet in
    height within 100 feet of an intersection did not limit them to
    enacting just that specified restriction. (Compare Television
    Transmission v. Public Util. Com. (1956) 
    47 Cal. 2d 82
    , 85; State
    Compensation Ins. Fund v. Workers' Comp. Appeals Bd. (
    69 Cal. App. 3d 884
    , 890; 11 Ops.Cal.Atty.Gen. 11, 12 (1948), with       People v.
    Western Airlines (1954) 
    42 Cal. 2d 621
    , 639; People v. Horner (1970)
    
    9 Cal. App. 3d 23
    , 27; Paramount Gen. Hosp. Co. v. National Medical
    Enterprises, Inc. (1974) 
    42 Cal. App. 3d 496
    , 501.)             Local
    authorities could now prohibit the parking of any vehicle within
    100 feet of an intersection, if required by the needs of traffic
    safety. Still, as we now see, this did not enable them to classify
    vehicles by type or size in order to single out particular ones for
    the sole purpose of restricting their parking in residential
    11
    areas.
    11
    It is suggested that the "but not limited to" language
    wrought by the 1985 amendment not only modifies "vehicles which are
    six feet or more in height" but also modifies "within 100 feet of
    any intersection."    It is thus suggested that after the 1985
    13.                           89-602
    Ordinarily, a grant of authority as is presently found in
    the wording of section 22507 would not be one of limitation (cf.,
    People v. Western 
    Airlines, supra
    , 42 Cal.2d at 639; People v.
    
    Horner, supra
    , 9 Cal.App.3d at 27; Paramount Gen. Hosp. Co. v.
    National Medical Enterprises, 
    Inc., supra
    , 42 Cal.App.3d at 501),
    and from it one might ordinarily imply an ability on the part of
    local agencies to impose other types of parking restrictions on
    oversized vehicles than the one specifically mentioned in the
    section, when required by the needs of traffic safety. Indeed,
    from the broadest consequence of the use of the phrase "including,
    but not limited to" one might even be able to ordinarily imply an
    ability on the part of local authorities to impose parking
    restrictions on those vehicles for reasons compelled by factors
    other than traffic safety --such as general safety considerations,
    or those of aesthetics. (Cf. fn. 2, ante.) But we do not deal
    with an "ordinary" grant of legislative authority.
    The grant of authority found in section 22507 deals with
    a facet of traffic regulation, and so when interpreting it we must
    be ever mindful of the dictate that the Legislature's delegation to
    local agencies of the power to make rules and regulations to
    regulate traffic is to be strictly construed (Rumford v. City of
    
    Berkeley, supra
    , 31 Cal.3d at 550, 553; City of Lafayette v. County
    of Contra 
    Costa, supra
    , 91 Cal.App.3d at 756; People v. 
    Moore, supra
    , 229 Cal.App.2d at 228; 67 Ops.Cal.Atty.Gen. 1, 
    4, supra
    ) and
    that "such authority must be `expressly (not impliedly) declared by
    the Legislature'." (City of Lafayette v. County of Contra 
    Costa, supra
    , quoting People v. 
    Moore, supra
    (emphasis the court's);
    accord, 67 
    Ops.Cal.Atty.Gen., supra
    .) " Expressly means `"in an
    amendment, local authorities were      given authority not only    to
    restrict the parking of any sized     vehicle within 100 feet of   an
    intersection, but to prohibit any     sized vehicle being parked   at
    places other than intersections,      if required by the needs     of
    traffic safety.
    We reject the suggestion.    It is more apparent from the
    history of the added language than from the current sentence
    structure, that the 1985 amendment was merely meant to clarify the
    change that was made the year before. That as we have seen, was to
    enable local agencies to provide better visibility at intersections
    by prohibiting the parking of one particular size of vehicle within
    the proximity of intersections. The 1985 amendment follows the
    same structural pattern in the overall section and added an
    authority to prohibit other categories of vehicles to the parking
    ban within 100 feet of an intersection. Thus, following the rule
    of strict construction for Vehicle Code provisions, we see this
    added authority as being limited to restricting the parking of
    additional categories of vehicles as would be reasonably calculated
    to improve visibility at intersections, and not a carte blanche to
    restrict their parking elsewhere.
    14.                           89-602
    express manner; in direct or unmistakable terms; explicitly;
    definitely; directly."' [Citations.]" (City of Lafayette v. County
    of Contra 
    Costa, supra
    at 756 fn. 3; emphasis the court's.)"
    We have shown how the basic general authority for local
    authorities to prohibit parking on certain streets and highways
    that is found in section 22057, does not give them authority to
    single out particular classes of vehicles for the imposition of
    parking restrictions. We have also shown how the amendment to the
    section in 1984 permitted local authorities to impose a parking
    restriction or prohibition on one particular class of vehicle in a
    particular situation involving parking near intersections, and how
    that was augmented by the amendment to the section in 1985, to
    permit them to impose the restriction on other types of vehicles in
    the same situation. Nowhere in section 22057 has the Legislature
    expressly, not impliedly, and in unmistakable language permitted
    local authorities to designate a particular class of vehicle,
    whether by type or size, solely to prohibit its parking in
    residential areas. Accordingly, we conclude that the section does
    not provide a basis for them to do so.
    B.   Section 22507.5.
    In section 22507.5 the Legislature has addressed        the
    ability of local authorities to prohibit the parking of           one
    particular type of vehicle in residential areas. Indeed, in       the
    section the Legislature has permitted them to do so               for
    considerations other than traffic safety.
    Like section 22507, section 22507.5 confers authority on
    local agencies to restrict vehicular parking on its streets. The
    section deals with the situation of overnight parking in general,
    but it also specifically permits local authorities to totally
    prohibit the parking of certain commercial vehicles on residential
    streets at any time. The section reads as follows:
    "(a)    Notwithstanding    Section   22507,    local
    authorities may, by ordinance or resolution, prohibit or
    restrict the parking or standing of vehicles on certain
    streets or highways, or portions thereof, between the
    hours of 2 a.m. and 6 a.m., and may, by ordinance or
    resolution, prohibit or restrict the parking or standing,
    on any street, or portion thereof, in a residential
    district, of commercial vehicles having a manufacturer's
    gross vehicle weight rating of 10,000 pounds or more.
    The ordinance or resolution relating to parking between
    the hours of 2 a.m. and 6 a.m. may provide for a system
    of permits for the purpose of exempting from the
    prohibition or restriction of the ordinance or resolution
    handicapped persons and residents of high-density,
    multiple-family dwelling areas or similar areas lacking
    adequate offstreet parking facilities. The ordinance or
    15.                           89-602
    resolution relating to the parking or standing of
    commercial vehicles in a residential district, however,
    shall not be effective with respect to any commercial
    vehicle making pickups or deliveries of goods, wares, and
    merchandise from or to any building or structure located
    on the restricted streets or highways or for the purpose
    of delivering materials to be used in the actual and bona
    fide repair, alteration, remodeling, or construction of
    any building or structure upon the restricted streets or
    highways for which a building permit has previously been
    obtained. [¶] (b) For the purpose of implementing this
    section, each local authority may, by ordinance, define
    the term `residential district' in accordance with its
    zoning ordinance. The ordinance shall not be effective
    unless the legislative body of the local authority holds
    a public hearing on the proposed ordinance prior to its
    adoption, with notice of the public hearing given in
    accordance with Section 65090 of the Government Code."
    (Emphases added.)
    Examining the section, we see that it begins with the
    phrase "Notwithstanding the provisions of Section 22507."      That
    indicates that section 22507.5 specifically controls over the
    provisions of Section 22507. (Cf. In re Marriage of Dover (1971)

    , 678 fn. 3; State of California v. Superior Court
    (1967)

    Court (1965) 
    238 Cal. App. 2d 691
    , 693-695.) This may seem somewhat
    puzzling because the relationship between the two sections is not
    immediately apparent.      But their interrelationship and the
    established precedence of section 22507.5 is explained in their
    history.
    In 1969, section 22507 was amended to add the
    requirement, now found in its third sentence, that signs or
    markings giving adequate notice of a parking restriction first be
    placed in order for the prohibition to apply. (Stats. 1969, ch.
    541, p. 1168. § 1.) Section 22507.5 was adopted at the same time
    to provide that "[n]otwithstanding [that provision], local
    authorities may by ordinance ... prohibit or restrict the parking
    or standing of vehicles on certain streets or highways ... between
    the hours of 2 a.m. and 6 a.m." (Stats. 1969, ch. 541, p. 1168, §
    2.) The Legislative Counsel's Digest to the Bill that enacted the
    section tells that the "notwithstanding language" was used to
    permit local authorities to restrict overnight parking "without
    placing such signs or markings." (1969 (Reg.Sess.) Sum.Dig. [AB
    699], p. 78.) Similarly, the Legislative Counsel's Digest to the
    Bill that amended section 22507.5 in 1975 to provide specific
    authorization for local authorities to exclude commercial vehicles
    from parking in residential neighborhoods tells that that was done
    to "permit[] local authorities to prohibit the parking ... of such
    vehicles in a residential district without placing such signs or
    markings...." (4 Stats. 1975, Sum.Dig. [AB 2272], p. 330; emphasis
    16.                           89-602
    added.)   Section 22507.5 thus understood, serves as a means by
    which the Legislature has authorized local agencies to restrict
    parking and to restrict the parking of certain vehicles without
    having to post the signs or notices of the restrictions that would
    otherwise be required by section 22507.
    Looking now to the substance of the section we see that
    it contains two basic authorizations for local authorities to
    restrict parking.    The first is general and permits them to
    prohibit or restrict overnight "parking ... of vehicles on certain
    streets or highways...." The second is more specific and pointed
    for it authorizes a total ban on the parking of some commercial
    vehicles in residential areas.
    The wording of the first authorization follows that of
    section 22507.   In both sections, the Legislature has used the
    adjective "certain" to modify the words "streets or highways" but
    it has not used it to modify the word "vehicles."           In our
    discussion of section 22507, we showed how that construction was
    indicative of an intent on the part of the Legislature to accord
    local authorities authority to designate particular streets for a
    parking restriction to apply, but not the authority to designate
    particular types of vehicles to apply it to. The same result would
    follow with the similarly worded authorization of section 22507.5.
    While the section might authorize a city to prohibit all vehicles
    from parking overnight on "certain streets or highways" in
    residential areas, it would not provide them authority to apply
    that restriction only to particularly designated types of vehicles.
    As with section 22507, any overnight parking restriction imposed
    for the streets of residential areas would have to equally apply to
    all vehicles that might park there, or to none.
    The second authorization of section 22507.5 permits local
    authorities to totally prohibit the parking of commercial vehicles
    having a manufacturer's gross vehicle weight rating of 10,000
    pounds or more in residential districts.           But other than
    authorizing a blanket prohibition on the parking of such commercial
    vehicles in residential districts, the section is silent as to what
    other types of vehicles may be similarly excluded. Constrained as
    we are to construe the authorization strictly and not imply things
    not expressly stated by the Legislature (Rumford v. City of
    
    Berkeley, supra
    , 31 Cal.3d at 550, 553; City of Lafayette v. County
    of Contra 
    Costa, supra
    , 91 Cal.App.3d at 756; People v. 
    Moore, supra
    , 229 Cal.App.2d at 228; 67 Ops.Cal.Atty.Gen. 1, 
    4, supra
    ), we
    conclude that that silence is indicative of the Legislature's
    intention that local agencies not have authority to prohibit or
    otherwise restrict the parking of other types of vehicles on
    residential streets.   Moreover, even without the rule dictating
    strict construction of Vehicle Code provisions, we would reach the
    same result. As the 1984 amendment to section 22507 showed with
    respect to the parking of oversized vehicles near intersections,
    section 22507.5 demonstrates that when the Legislature has wanted
    17.                           89-602
    to grant local authorities the power to enact an ordinance
    prohibiting the parking of a particular type of vehicle in
    residential areas, it has specifically done so. That it has not
    with respect to other types of vehicles would indicate that local
    agencies were not to have authority to similarly prohibit their
    parking. (Cf. Wildlife Alive v. 
    Chickering, supra
    , 18 Cal.3d at
    196; Safer v. Superior 
    Court, supra
    , 15 Cal.3d at 236, 238; DeWeese
    v. 
    Unick, supra
    , 102 Cal.App.3d at 106; Board of Trustees v. 
    Judge, supra
    , 50 Cal.App.3d at 927;     Rich v. State Board of 
    Optometry, supra
    , 235 Cal.App.2d at 607.)
    As our Supreme Court said in Rumford:
    "Most   traffic    laws   are    to   some    extent
    discriminatory. In large measure they determine which
    traffic may use streets under what circumstances.
    Nonetheless, localities have no carte blanche and, absent
    express authority, may not determine which traffic shall
    and which shall not use streets." ( Rumford v. City of
    
    Berkeley, supra
    , 
    31 Cal. 3d 545
    , 554.)
    Under section 22507.5, a municipality could exclude commercial
    vehicles from parking in residential neighborhoods; indeed, it
    could do so purely for reasons of aesthetics. (See e.g., People v.
    Tolman (1980) 
    110 Cal. App. Supp. 3d 6
    , 10.) But "unless sanctioned
    by some provision of state law" (Bentley v. 
    Chapman, supra
    , 113
    Cal.App.2d at 3), a city council would be without authority to
    similarly prohibit other classes of vehicles from parking on those
    streets as well.    We have shown how neither section 22507 nor
    section 22507.5 provides express authority for a city to designate
    other classes of vehicles for the purpose of restricting their
    parking in such areas, whether on public health grounds, on public
    safety grounds, or on any other ground, and how no such authority
    may be implied.
    We therefore conclude that other than prohibiting or
    otherwise restricting the parking of commercial vehicles having a
    manufacturer's gross vehicle weight rating of 10,000 pounds or
    more, a California city has no authority to prohibit the parking of
    particular categories of vehicles on its residential streets.
