1		AN ACT concerning transportation.
2		Be it enacted by the People of the State of Illinois,
3		represented in the General Assembly:
4		Section 5. The Illinois Vehicle Code is amended by changing
5		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
9		tires may be operated, unladen or with load, when the total
10		weight on the road surface exceeds the following: 20,000 pounds
11		on a single axle; 34,000 pounds on a tandem axle with no axle
12		within the tandem exceeding 20,000 pounds; 80,000 pounds gross
13		weight for vehicle combinations of 5 or more axles; or a total
14		weight on a group of 2 or more consecutive axles in excess of
15		that weight produced by the application of the following
16		formula: W = 500 times the sum of (LN divided by N-1) + 12N +
17		36, where "W" equals overall total weight on any group of 2 or
18		more consecutive axles to the nearest 500 pounds, "L" equals
19		the distance measured to the nearest foot between extremes of
20		any group of 2 or more consecutive axles, and "N" equals the
21		number of axles in the group under consideration.
22		The above formula when expressed in tabular form results in
23		allowable loads as follows:

12		(3) Cities having a population of more than 50,000 may
13		permit by ordinance axle loads on 2 axle motor vehicles 33
14		1/2% above those provided for herein, but the increase
15		shall not become effective until the city has officially
16		notified the Department of the passage of the ordinance and
17		shall not apply to those vehicles when outside of the
18		limits of the city, nor shall the gross weight of any 2
19		axle motor vehicle operating over any street of the city
20		exceed 40,000 pounds.

15		(11) The maximum weight allowed on a vehicle with
16		crawler type tracks is 40,000 pounds.
17		(12) A combination of vehicles, including a tow truck
18		and a disabled vehicle or disabled combination of vehicles,
19		that exceeds the weight restriction imposed by this Code,
20		may be operated on a public highway in this State provided
21		that neither the disabled vehicle nor any vehicle being
22		towed nor the tow truck itself shall exceed the weight
23		limitations permitted under this Chapter. During the
24		towing operation, neither the tow truck nor the vehicle
25		combination shall exceed 24,000 pounds on a single rear
26		axle and 44,000 pounds on a tandem rear axle, provided the

HB2310 Engrossed - 9 - LRB098 08019 MLW 38110 b
1		towing vehicle:
2		(i) is specifically designed as a tow truck having
3		a gross vehicle weight rating of at least 18,000 pounds
4		and is equipped with air brakes, provided that air
5		brakes are required only if the towing vehicle is
6		towing a vehicle, semitrailer, or tractor-trailer
7		combination that is equipped with air brakes;
8		(ii) is equipped with flashing, rotating, or
9		oscillating amber lights, visible for at least 500 feet
10		in all directions;
11		(iii) is capable of utilizing the lighting and
12		braking systems of the disabled vehicle or combination
13		of vehicles; and
14		(iv) does not engage in a tow exceeding 20 miles
15		from the initial point of wreck or disablement. Any
16		additional movement of the vehicles may occur only upon
17		issuance of authorization for that movement under the
18		provisions of Sections 15-301 through 15-319 of this
19		Code. The towing vehicle, however, may tow any disabled
20		vehicle to a point where repairs are actually to occur.
21		This movement shall be valid only on State routes. The
22		tower must abide by posted bridge weight limits.
23		Gross weight limits shall not apply to the combination of
24		the tow truck and vehicles being towed. The tow truck license
25		plate must cover the operating empty weight of the tow truck
26		only. The weight of each vehicle being towed shall be covered

HB2310 Engrossed - 10 - LRB098 08019 MLW 38110 b
1		by a valid license plate issued to the owner or operator of the
2		vehicle being towed and displayed on that vehicle. If no valid
3		plate issued to the owner or operator of that vehicle is
4		displayed on that vehicle, or the plate displayed on that
5		vehicle does not cover the weight of the vehicle, the weight of
6		the vehicle shall be covered by the third tow truck plate
7		issued to the owner or operator of the tow truck and
8		temporarily affixed to the vehicle being towed. If a roll-back
9		carrier is registered and being used as a tow truck, however,
10		the license plate or plates for the tow truck must cover the
11		gross vehicle weight, including any load carried on the bed of
12		the roll-back carrier.
13		The Department may by rule or regulation prescribe
14		additional requirements. However, nothing in this Code shall
15		prohibit a tow truck under instructions of a police officer
16		from legally clearing a disabled vehicle, that may be in
17		violation of weight limitations of this Chapter, from the
18		roadway to the berm or shoulder of the highway. If in the
19		opinion of the police officer that location is unsafe, the
20		officer is authorized to have the disabled vehicle towed to the
21		nearest place of safety.
22		For the purpose of this subsection, gross vehicle weight
23		rating, or GVWR, means the value specified by the manufacturer
24		as the loaded weight of the tow truck.
25		(b) As used in this Section, "recycling haul" or "recycling
26		operation" means the hauling of non-hazardous, non-special,

HB2310 Engrossed - 11 - LRB098 08019 MLW 38110 b
1		non-putrescible materials, such as paper, glass, cans, or
2		plastic, for subsequent use in the secondary materials market.
3		(c) No vehicle or combination of vehicles equipped with
4		pneumatic tires shall be operated, unladen or with load, upon
5		the highways of this State in violation of the provisions of
6		any permit issued under the provisions of Sections 15-301
7		through 15-319 of this Chapter.
8		(d) No vehicle or combination of vehicles equipped with
9		other than pneumatic tires may be operated, unladen or with
10		load, upon the highways of this State when the gross weight on
11		the road surface through any wheel exceeds 800 pounds per inch
12		width of tire tread or when the gross weight on the road
13		surface through any axle exceeds 16,000 pounds.
14		(e) No person shall operate a vehicle or combination of
15		vehicles over a bridge or other elevated structure constituting
16		part of a highway with a gross weight that is greater than the
17		maximum weight permitted by the Department, when the structure
18		is sign posted as provided in this Section.
19		(f) The Department upon request from any local authority
20		shall, or upon its own initiative may, conduct an investigation
21		of any bridge or other elevated structure constituting a part
22		of a highway, and if it finds that the structure cannot with
23		safety to itself withstand the weight of vehicles otherwise
24		permissible under this Code the Department shall determine and
25		declare the maximum weight of vehicles that the structures can
26		withstand, and shall cause or permit suitable signs stating

HB2310 Engrossed - 12 - LRB098 08019 MLW 38110 b
1		maximum weight to be erected and maintained before each end of
2		the structure. No person shall operate a vehicle or combination
3		of vehicles over any structure with a gross weight that is
4		greater than the posted maximum weight.
5		(g) Upon the trial of any person charged with a violation
6		of subsection (e) or (f) of this Section, proof of the
7		determination of the maximum allowable weight by the Department
8		and the existence of the signs, constitutes conclusive evidence
9		of the maximum weight that can be maintained with safety to the
10		bridge or structure.
