2    AMENDMENT NO. ______. Amend Senate Bill 3574 by replacing
3everything after the enacting clause with the following:
4    "Section 5. The Illinois Vehicle Code is amended by
5changing Section 15-111 as follows:
6    (625 ILCS 5/15-111)  (from Ch. 95 1/2, par. 15-111)
7    Sec. 15-111. Wheel and axle loads and gross weights.
8    (a) No vehicle or combination of vehicles with pneumatic
9tires may be operated, unladen or with load, when the total
10weight on the road surface exceeds the following: 20,000 pounds
11on a single axle; 34,000 pounds on a tandem axle with no axle
12within the tandem exceeding 20,000 pounds; 80,000 pounds gross
13weight for vehicle combinations of 5 or more axles; or a total
14weight on a group of 2 or more consecutive axles in excess of
15that weight produced by the application of the following
16formula: W = 500 times the sum of (LN divided by N-1) + 12N +



09800SB3574sam001- 2 -LRB098 18847 MLW 57232 a

136, where "W" equals overall total weight on any group of 2 or
2more consecutive axles to the nearest 500 pounds, "L" equals
3the distance measured to the nearest foot between extremes of
4any group of 2 or more consecutive axles, and "N" equals the
5number of axles in the group under consideration.
6    The above formula when expressed in tabular form results in
7allowable loads as follows:
8Distance measured
9to the nearest
10foot between the
11extremes of any         Maximum weight in pounds

19*If the distance between 2 axles is 96 inches or less, the 2
20axles are tandem axles and the maximum total weight may not
21exceed 34,000 pounds, notwithstanding the higher limit
22resulting from the application of the formula.
23    Vehicles not in a combination having more than 4 axles may
24not exceed the weight in the table in this subsection (a) for 4
25axles measured between the extreme axles of the vehicle.
26    Vehicles in a combination having more than 6 axles may not



09800SB3574sam001- 5 -LRB098 18847 MLW 57232 a

1exceed the weight in the table in this subsection (a) for 6
2axles measured between the extreme axles of the combination.
3    Local authorities, with respect to streets and highways
4under their jurisdiction, without additional fees, may also by
5ordinance or resolution allow the weight limitations of this
6subsection, provided the maximum gross weight on any one axle
7shall not exceed 20,000 pounds and the maximum total weight on
8any tandem axle shall not exceed 34,000 pounds, on designated
9highways when appropriate regulatory signs giving notice are
10erected upon the street or highway or portion of any street or
11highway affected by the ordinance or resolution.

22    shall not become effective until the city has officially
23    notified the Department of the passage of the ordinance and
24    shall not apply to those vehicles when outside of the
25    limits of the city, nor shall the gross weight of any 2
26    axle motor vehicle operating over any street of the city

09800SB3574sam001- 10 -LRB098 18847 MLW 57232 a

1            (i) is specifically designed as a tow truck having
2        a gross vehicle weight rating of at least 18,000 pounds
3        and is equipped with air brakes, provided that air
4        brakes are required only if the towing vehicle is
5        towing a vehicle, semitrailer, or tractor-trailer
6        combination that is equipped with air brakes;
7            (ii) is equipped with flashing, rotating, or
8        oscillating amber lights, visible for at least 500 feet
9        in all directions;
10            (iii) is capable of utilizing the lighting and
11        braking systems of the disabled vehicle or combination
12        of vehicles; and
13            (iv) does not engage in a tow exceeding 20 miles
14        from the initial point of wreck or disablement. Any
15        additional movement of the vehicles may occur only upon
16        issuance of authorization for that movement under the
17        provisions of Sections 15-301 through 15-319 of this
18        Code. The towing vehicle, however, may tow any disabled
19        vehicle to a point where repairs are actually to occur.
20        This movement shall be valid only on State routes. The
21        tower must abide by posted bridge weight limits.
22    Gross weight limits shall not apply to the combination of
23the tow truck and vehicles being towed. The tow truck license
24plate must cover the operating empty weight of the tow truck
25only. The weight of each vehicle being towed shall be covered
26by a valid license plate issued to the owner or operator of the



09800SB3574sam001- 11 -LRB098 18847 MLW 57232 a

1vehicle being towed and displayed on that vehicle. If no valid
2plate issued to the owner or operator of that vehicle is
3displayed on that vehicle, or the plate displayed on that
4vehicle does not cover the weight of the vehicle, the weight of
5the vehicle shall be covered by the third tow truck plate
6issued to the owner or operator of the tow truck and
7temporarily affixed to the vehicle being towed. If a roll-back
8carrier is registered and being used as a tow truck, however,
9the license plate or plates for the tow truck must cover the
10gross vehicle weight, including any load carried on the bed of
11the roll-back carrier.
12    The Department may by rule or regulation prescribe
13additional requirements. However, nothing in this Code shall
14prohibit a tow truck under instructions of a police officer
15from legally clearing a disabled vehicle, that may be in
16violation of weight limitations of this Chapter, from the
17roadway to the berm or shoulder of the highway. If in the
18opinion of the police officer that location is unsafe, the
19officer is authorized to have the disabled vehicle towed to the
20nearest place of safety.
21    For the purpose of this subsection, gross vehicle weight
22rating, or GVWR, means the value specified by the manufacturer
23as the loaded weight of the tow truck.
24    (b) As used in this Section, "recycling haul" or "recycling
25operation" means the hauling of non-hazardous, non-special,
26non-putrescible materials, such as paper, glass, cans, or



09800SB3574sam001- 12 -LRB098 18847 MLW 57232 a

1plastic, for subsequent use in the secondary materials market.
2    (c) No vehicle or combination of vehicles equipped with
3pneumatic tires shall be operated, unladen or with load, upon
4the highways of this State in violation of the provisions of
5any permit issued under the provisions of Sections 15-301
6through 15-319 of this Chapter.
7    (d) No vehicle or combination of vehicles equipped with
8other than pneumatic tires may be operated, unladen or with
9load, upon the highways of this State when the gross weight on
10the road surface through any wheel exceeds 800 pounds per inch
11width of tire tread or when the gross weight on the road
12surface through any axle exceeds 16,000 pounds.
13    (e) No person shall operate a vehicle or combination of
14vehicles over a bridge or other elevated structure constituting
15part of a highway with a gross weight that is greater than the
16maximum weight permitted by the Department, when the structure
17is sign posted as provided in this Section.
18    (f) The Department upon request from any local authority
19shall, or upon its own initiative may, conduct an investigation
20of any bridge or other elevated structure constituting a part
21of a highway, and if it finds that the structure cannot with
22safety to itself withstand the weight of vehicles otherwise
23permissible under this Code the Department shall determine and
24declare the maximum weight of vehicles that the structures can
25withstand, and shall cause or permit suitable signs stating
26maximum weight to be erected and maintained before each end of



09800SB3574sam001- 13 -LRB098 18847 MLW 57232 a

1the structure. No person shall operate a vehicle or combination
2of vehicles over any structure with a gross weight that is
3greater than the posted maximum weight.
4    (g) Upon the trial of any person charged with a violation
5of subsection (e) or (f) of this Section, proof of the
6determination of the maximum allowable weight by the Department
7and the existence of the signs, constitutes conclusive evidence
8of the maximum weight that can be maintained with safety to the
9bridge or structure.
10    (h) The weight limitations of this Section are increased by
112,000 pounds for vehicles that use natural gas as a motor fuel.
