    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.
    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
    permits under authority of Section 15-301 of this Code.
    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.
        (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 a
    tandem axle; 40,000 pounds gross weight on a 2-axle
    vehicle; 54,000 pounds gross weight on a 3-axle vehicle.
    This vehicle is not subject to the bridge formula.
        (8) Tandem axles on a 3-axle truck registered as a
    Special Hauling Vehicle, manufactured prior to or in the
    model year of 2024 2014 and first registered in Illinois
    prior to January 1, 2025 2015, 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
    exceed 20,000 pounds. Any vehicle of this type manufactured
    after the model year of 2024 2014 or first registered in
    Illinois after December 31, 2024 2014 may not exceed a
    combined weight of 34,000 pounds through the series of 2
    axles and neither axle of the series may exceed 20,000
    pounds.
        (9) A 4-axle truck mixer registered as a Special
    Hauling Vehicle, used exclusively for the mixing and
    transportation of concrete in the plastic state,
    manufactured before or in the model year of 2024 2014,
    first registered in Illinois before January 1, 2025 2015,
    and not 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 2014, and registered
    in Illinois prior to January 1, 2025 2015, 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 2014 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 15-319 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.
    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 15-319 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.
