    AN ACT concerning transportation.
 
    Be it enacted by the People of the State of Illinois,
represented in the General Assembly:
 
    Section 5. The Illinois Vehicle Code is amended by
changing Section 15-111 as follows:
 
    (625 ILCS 5/15-111)  (from Ch. 95 1/2, par. 15-111)
    Sec. 15-111. Wheel and axle loads and gross weights.
    (a) No vehicle or combination of vehicles with pneumatic
tires may be operated, unladen or with load, when the total
weight on the road surface exceeds the following: 20,000
pounds on a single axle; 34,000 pounds on a tandem axle with no
axle within the tandem exceeding 20,000 pounds; 80,000 pounds
gross weight for vehicle combinations of 5 or more axles; or a
total weight on a group of 2 or more consecutive axles in
excess of that weight produced by the application of the
following formula: W = 500 times the sum of (LN divided by N-1)
+ 12N + 36, where "W" equals overall total weight on any group
of 2 or more consecutive axles to the nearest 500 pounds, "L"
equals the distance measured to the nearest foot between
extremes of any group of 2 or more consecutive axles, and "N"
equals the number of axles in the group under consideration.
    The above formula when expressed in tabular form results
in allowable loads as follows:

*If the distance between 2 axles is 96 inches or less, the 2
axles are tandem axles and the maximum total weight may not
exceed 34,000 pounds, notwithstanding the higher limit
resulting from the application of the formula.
**Two consecutive sets of tandem axles may carry 34,000 pounds
each if the overall distance between the first and last axles
of these tandems is 36 feet or more.
    Vehicles not in a combination having more than 4 axles may
not exceed the weight in the table in this subsection (a) for 4
axles measured between the extreme axles of the vehicle.
    Vehicles in a combination having more than 6 axles may not
exceed the weight in the table in this subsection (a) for 6
axles measured between the extreme axles of the combination.
    Local authorities, with respect to streets and highways
under their jurisdiction, without additional fees, may also by
ordinance or resolution allow the weight limitations of this
subsection, provided the maximum gross weight on any one axle
shall not exceed 20,000 pounds and the maximum total weight on
any tandem axle shall not exceed 34,000 pounds, on designated
highways when appropriate regulatory signs giving notice are
erected upon the street or highway or portion of any street or
highway affected by the ordinance or resolution.
    The following are exceptions to the above formula:
        (1) Vehicles for which a different limit is
    established and posted in accordance with Section 15-316
    of this Code.
        (2) Vehicles for which the Department of
    Transportation and local authorities issue overweight

    These vehicles are not subject to the bridge formula.
        (3) Cities having a population of more than 50,000 may
    permit by ordinance axle loads on 2-axle motor vehicles 33
    1/2% above those provided for herein, but the increase
    shall not become effective until the city has officially
    notified the Department of the passage of the ordinance
    and shall not apply to those vehicles when outside of the
    limits of the city, nor shall the gross weight of any
    2-axle motor vehicle operating over any street of the city
    exceed 40,000 pounds.
        (4) Weight limitations shall not apply to vehicles
    (including loads) operated by a public utility when
    transporting equipment required for emergency repair of
    public utility facilities or properties or water wells.
        (4.5) A 3-axle or 4-axle vehicle (including when
    laden) operated or hired by a municipality within Cook,
    Lake, McHenry, Kane, DuPage, or Will county being operated
    for the purpose of performing emergency sewer repair that
    would be subject to a weight limitation less than 66,000
    pounds under the formula in this subsection (a) shall have
    a weight limitation of 66,000 pounds or the vehicle's
    gross vehicle weight rating, whichever is less. This
    paragraph (4.5) does not apply to vehicles being operated
    on the National System of Interstate and Defense Highways,
    or to vehicles being operated on bridges or other elevated
    structures constituting a part of a highway.
        (5) Two consecutive sets of tandem axles may carry a
    total weight of 34,000 pounds each if the overall distance
    between the first and last axles of the consecutive sets
    of tandem axles is 36 feet or more, notwithstanding the
    lower limit resulting from the application of the above
    formula.
        (6) A truck, not in combination and used exclusively
    for the collection of rendering materials, may, when
    laden, transmit upon the road surface, except when on part
    of the National System of Interstate and Defense Highways,
    the following maximum weights: 22,000 pounds on a single
    axle; 40,000 pounds on a tandem axle.
        (7) A truck not in combination, equipped with a self
    compactor or an industrial roll-off hoist and roll-off
    container, used exclusively for garbage, refuse, or
    recycling operations, may, when laden, transmit upon the
    road surface, except when on part of the National System
    of Interstate and Defense Highways, the following maximum
    weights: 22,000 pounds on a single axle; 40,000 pounds on

    and Defense Highways, the following maximum weights:
    22,000 pounds on single axle; 40,000 pounds on a tandem
    axle; 54,000 pounds gross weight on a 3-axle vehicle. This
    vehicle is not subject to the bridge formula.
        (8) Except as provided in paragraph (7.5) of this
    subsection (a), tandem axles on a 3-axle truck registered
    as a Special Hauling Vehicle, manufactured prior to or in
    the model year of 2024 and first registered in Illinois
    prior to January 1, 2025, with a distance greater than 72
    inches but not more than 96 inches between any series of 2
    axles, is allowed a combined weight on the series not to
    exceed 36,000 pounds and neither axle of the series may

    operated on a highway that is part of the National System
    of Interstate Highways, is allowed the following maximum
    weights: 20,000 pounds on any single axle; 36,000 pounds
    on a series of axles greater than 72 inches but not more
    than 96 inches; and 34,000 pounds on any series of 2 axles
    greater than 40 inches but not more than 72 inches. The
    gross weight of this vehicle may not exceed the weights
    allowed by the bridge formula for 4 axles. The bridge
    formula does not apply to any series of 3 axles while the
    vehicle is transporting concrete in the plastic state, but
    no axle or tandem axle of the series may exceed the maximum
    weight permitted under this paragraph (9) of subsection
    (a).
        (10) Combinations of vehicles, registered as Special
    Hauling Vehicles that include a semitrailer manufactured
    prior to or in the model year of 2024, and registered in
    Illinois prior to January 1, 2025, having 5 axles with a
    distance of 42 feet or less between extreme axles, may not
    exceed the following maximum weights: 20,000 pounds on a
    single axle; 34,000 pounds on a tandem axle; and 72,000
    pounds gross weight. This combination of vehicles is not
    subject to the bridge formula. For all those combinations
    of vehicles that include a semitrailer manufactured after
    the effective date of P.A. 92-0417, the overall distance
    between the first and last axles of the 2 sets of tandems
    must be 18 feet 6 inches or more. Any combination of
    vehicles that has had its cargo container replaced in its
    entirety after December 31, 2024 may not exceed the
    weights allowed by the bridge formula.
        (11) The maximum weight allowed on a vehicle with
    crawler type tracks is 40,000 pounds.
        (12) A combination of vehicles, including a tow truck
    and a disabled vehicle or disabled combination of
    vehicles, that exceeds the weight restriction imposed by
    this Code, may be operated on a public highway in this
    State provided that neither the disabled vehicle nor any
    vehicle being towed nor the tow truck itself shall exceed
    the weight limitations permitted under this Chapter.
    During the towing operation, neither the tow truck nor the
    vehicle combination shall exceed 24,000 pounds on a single
    rear axle and 44,000 pounds on a tandem rear axle,
    provided the towing vehicle:
            (i) is specifically designed as a tow truck having
        a gross vehicle weight rating of at least 18,000
        pounds and is equipped with air brakes, provided that
        air brakes are required only if the towing vehicle is
        towing a vehicle, semitrailer, or tractor-trailer
        combination that is equipped with air brakes;
            (ii) is equipped with flashing, rotating, or
        oscillating amber lights, visible for at least 500
        feet in all directions;
            (iii) is capable of utilizing the lighting and
        braking systems of the disabled vehicle or combination
        of vehicles; and
            (iv) does not engage in a tow exceeding 20 miles
        from the initial point of wreck or disablement. Any
        additional movement of the vehicles may occur only
        upon issuance of authorization for that movement under
        the provisions of Sections 15-301 through 15-318 of
        this Code. The towing vehicle, however, may tow any
        disabled vehicle to a point where repairs are actually
        to occur. This movement shall be valid only on State
        routes. The tower must abide by posted bridge weight
        limits.
        (12.5) The vehicle weight limitations in this Section
    do not apply to a covered heavy duty tow and recovery
    vehicle. The covered heavy duty tow and recovery vehicle
    license plate must cover the operating empty weight of the
    covered heavy duty tow and recovery vehicle only.
        (13) Upon and during a declaration of an emergency
    propane supply disaster by the Governor under Section 7 of
    the Illinois Emergency Management Agency Act:
            (i) a truck not in combination, equipped with a
        cargo tank, used exclusively for the transportation of
        propane or liquefied petroleum gas may, when laden,
        transmit upon the road surface, except when on part of
        the National System of Interstate and Defense
        Highways, the following maximum weights: 22,000 pounds
        on a single axle; 40,000 pounds on a tandem axle;
        40,000 pounds gross weight on a 2-axle vehicle; 54,000
        pounds gross weight on a 3-axle vehicle; and
            (ii) a truck when in combination with a trailer
        equipped with a cargo tank used exclusively for the
        transportation of propane or liquefied petroleum gas
        may, when laden, transmit upon the road surface,
        except when on part of the National System of
        Interstate and Defense Highways, the following maximum
        weights: 22,000 pounds on a single axle; 40,000 pounds
        on a tandem axle; 90,000 pounds gross weight on a
        5-axle or 6-axle vehicle.
        Vehicles operating under this paragraph (13) are not
    subject to the bridge formula.
        (14) A vehicle or combination of vehicles that uses
    either natural gas or propane gas as a motor fuel or is
    operated by an engine fueled wholly or partially by an
    electric battery or hydrogen fuel cell electric fueling
    system may exceed the above weight limitations by up to
    2,000 pounds, the total allowance is calculated by an
    amount that is equal to the difference between the weight
    of the vehicle attributable to the natural gas or propane
    or hydrogen gas tank, batteries, and fueling system
    carried by the vehicle, and the weight of a comparable
    diesel tank and fueling system. This paragraph (14) shall
    not allow a vehicle to exceed any posted weight limit on a
    highway or structure.
        (15) An emergency vehicle or fire apparatus that is a
    vehicle designed to be used under emergency conditions to
    transport personnel and equipment, and used to support the
    suppression of fires and mitigation of other hazardous
    situations on a Class I highway, may not exceed 86,000
    pounds gross weight, or any of the following weight
    allowances:
            (i) 24,000 pounds on a single steering axle;
            (ii) 33,500 pounds on a single drive axle;
            (iii) 62,000 pounds on a tandem axle; or
            (iv) 52,000 pounds on a tandem rear drive steer
        axle.
        (16) A bus, motor coach, or recreational vehicle may
    carry a total weight of 24,000 pounds on a single axle, but
    may not exceed other weight provisions of this Section.
    Gross weight limits shall not apply to the combination of
the tow truck and vehicles being towed. The tow truck license
plate must cover the operating empty weight of the tow truck
only. The weight of each vehicle being towed shall be covered
by a valid license plate issued to the owner or operator of the
vehicle being towed and displayed on that vehicle. If no valid
plate issued to the owner or operator of that vehicle is
displayed on that vehicle, or the plate displayed on that
vehicle does not cover the weight of the vehicle, the weight of
the vehicle shall be covered by the third tow truck plate
issued to the owner or operator of the tow truck and
temporarily affixed to the vehicle being towed. If a roll-back
carrier is registered and being used as a tow truck, however,
the license plate or plates for the tow truck must cover the
gross vehicle weight, including any load carried on the bed of
the roll-back carrier.
    The Department may by rule or regulation prescribe
additional requirements. However, nothing in this Code shall
prohibit a tow truck under instructions of a police officer
from legally clearing a disabled vehicle, that may be in
violation of weight limitations of this Chapter, from the
roadway to the berm or shoulder of the highway. If in the
opinion of the police officer that location is unsafe, the
officer is authorized to have the disabled vehicle towed to
the nearest place of safety.
    For the purpose of this subsection, gross vehicle weight
rating, or GVWR, means the value specified by the manufacturer
as the loaded weight of the tow truck.
    (b) As used in this Section, "recycling haul" or
"recycling operation" means the hauling of non-hazardous,
non-special, non-putrescible materials, such as paper, glass,
cans, or plastic, for subsequent use in the secondary
materials market.
    (c) No vehicle or combination of vehicles equipped with
pneumatic tires shall be operated, unladen or with load, upon
the highways of this State in violation of the provisions of
any permit issued under the provisions of Sections 15-301
through 15-318 of this Chapter.
    (d) No vehicle or combination of vehicles equipped with
other than pneumatic tires may be operated, unladen or with
load, upon the highways of this State when the gross weight on
the road surface through any wheel exceeds 800 pounds per inch
width of tire tread or when the gross weight on the road
surface through any axle exceeds 16,000 pounds.
    (e) No person shall operate a vehicle or combination of
vehicles over a bridge or other elevated structure
constituting part of a highway with a gross weight that is
greater than the maximum weight permitted by the Department,
when the structure is sign posted as provided in this Section.
    (f) The Department upon request from any local authority
shall, or upon its own initiative may, conduct an
investigation of any bridge or other elevated structure
constituting a part of a highway, and if it finds that the
structure cannot with safety to itself withstand the weight of
vehicles otherwise permissible under this Code the Department
shall determine and declare the maximum weight of vehicles
that the structures can withstand, and shall cause or permit
suitable signs stating maximum weight to be erected and
maintained before each end of the structure. No person shall
operate a vehicle or combination of vehicles over any
structure with a gross weight that is greater than the posted
maximum weight.
    (g) Upon the trial of any person charged with a violation
of subsection (e) or (f) of this Section, proof of the
determination of the maximum allowable weight by the
Department and the existence of the signs, constitutes
conclusive evidence of the maximum weight that can be
maintained with safety to the bridge or structure.
