2    AMENDMENT NO. ______. Amend Senate Bill 3505 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 +



09700SB3505sam001- 2 -LRB097 18226 HEP 66825 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



09700SB3505sam001- 5 -LRB097 18226 HEP 66825 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

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

7    total weight of 34,000 pounds each if the overall distance
8    between the first and last axles of the consecutive sets of
9    tandem axles is 36 feet or more, notwithstanding the lower
10    limit resulting from the application of the above formula.

20        a gross vehicle weight rating of at least 18,000 pounds
21        and is equipped with air brakes, provided that air
22        brakes are required only if the towing vehicle is
23        towing a vehicle, semitrailer, or tractor-trailer
24        combination that is equipped with air brakes;
25            (ii) is equipped with flashing, rotating, or
26        oscillating amber lights, visible for at least 500 feet



09700SB3505sam001- 10 -LRB097 18226 HEP 66825 a

1        in all directions;
2            (iii) is capable of utilizing the lighting and
3        braking systems of the disabled vehicle or combination
4        of vehicles; and
5            (iv) does not engage in a tow exceeding 20 miles
6        from the initial point of wreck or disablement. Any
7        additional movement of the vehicles may occur only upon
8        issuance of authorization for that movement under the
9        provisions of Sections 15-301 through 15-319 of this
10        Code. The towing vehicle, however, may tow any disabled
11        vehicle to a point where repairs are actually to occur.
12        This movement shall be valid only on State routes. The
13        tower must abide by posted bridge weight limits.
14    Gross weight limits shall not apply to the combination of
15the tow truck and vehicles being towed. The tow truck license
16plate must cover the operating empty weight of the tow truck
17only. The weight of each vehicle being towed shall be covered
18by a valid license plate issued to the owner or operator of the
19vehicle being towed and displayed on that vehicle. If no valid
20plate issued to the owner or operator of that vehicle is
21displayed on that vehicle, or the plate displayed on that
22vehicle does not cover the weight of the vehicle, the weight of
23the vehicle shall be covered by the third tow truck plate
24issued to the owner or operator of the tow truck and
25temporarily affixed to the vehicle being towed. If a roll-back
26carrier is registered and being used as a tow truck, however,



09700SB3505sam001- 11 -LRB097 18226 HEP 66825 a

1the license plate or plates for the tow truck must cover the
2gross vehicle weight, including any load carried on the bed of
3the roll-back carrier.
4    The Department may by rule or regulation prescribe
5additional requirements. However, nothing in this Code shall
6prohibit a tow truck under instructions of a police officer
7from legally clearing a disabled vehicle, that may be in
8violation of weight limitations of this Chapter, from the
9roadway to the berm or shoulder of the highway. If in the
10opinion of the police officer that location is unsafe, the
11officer is authorized to have the disabled vehicle towed to the
12nearest place of safety.
13    For the purpose of this subsection, gross vehicle weight
14rating, or GVWR, means the value specified by the manufacturer
15as the loaded weight of the tow truck.
16    (b) As used in this Section, "recycling haul" or "recycling
17operation" means the hauling of non-hazardous, non-special,
18non-putrescible materials, such as paper, glass, cans, or
19plastic, for subsequent use in the secondary materials market.
20    (c) No vehicle or combination of vehicles equipped with
21pneumatic tires shall be operated, unladen or with load, upon
22the highways of this State in violation of the provisions of
23any permit issued under the provisions of Sections 15-301
24through 15-319 of this Chapter.
25    (d) No vehicle or combination of vehicles equipped with
26other than pneumatic tires may be operated, unladen or with



09700SB3505sam001- 12 -LRB097 18226 HEP 66825 a

1load, upon the highways of this State when the gross weight on
2the road surface through any wheel exceeds 800 pounds per inch
3width of tire tread or when the gross weight on the road
4surface through any axle exceeds 16,000 pounds.
5    (e) No person shall operate a vehicle or combination of
6vehicles over a bridge or other elevated structure constituting
7part of a highway with a gross weight that is greater than the
8maximum weight permitted by the Department, when the structure
9is sign posted as provided in this Section.
10    (f) The Department upon request from any local authority
11shall, or upon its own initiative may, conduct an investigation
12of any bridge or other elevated structure constituting a part
13of a highway, and if it finds that the structure cannot with
14safety to itself withstand the weight of vehicles otherwise
15permissible under this Code the Department shall determine and
16declare the maximum weight of vehicles that the structures can
17withstand, and shall cause or permit suitable signs stating
18maximum weight to be erected and maintained before each end of
19the structure. No person shall operate a vehicle or combination
20of vehicles over any structure with a gross weight that is
21greater than the posted maximum weight.
22    (g) Upon the trial of any person charged with a violation
23of subsection (e) or (f) of this Section, proof of the
24determination of the maximum allowable weight by the Department
25and the existence of the signs, constitutes conclusive evidence
26of the maximum weight that can be maintained with safety to the



09700SB3505sam001- 13 -LRB097 18226 HEP 66825 a

1bridge or structure.
