6 changing Section 15-111 as follows:
7 (625 ILCS 5/15-111) (from Ch. 95 1/2, par. 15-111)
8 Sec. 15-111. Wheel and axle loads and gross weights.
9 (a) No vehicle or combination of vehicles equipped with
10 pneumatic tires shall be operated, unladen or with load, upon
11 the highways of this State when the gross weight on the road
12 surface through any single axle thereof exceeds 18,000
13 pounds, except when a different limit is established and
14 posted in accordance with Section 15-316 and except any
15 single axle of a 2 axle motor vehicle weighing 36,000 pounds
16 or less and not a part of a combination of vehicles, shall
17 not exceed 20,000 pounds. Provided, however, that any single
18 axle of a 2 axle motor vehicle equipped with a personnel lift
19 or digger derrick, weighing 36,000 pounds or less, owned and
20 operated by a public utility, shall not exceed 20,000 pounds.
21 No vehicle or combination of vehicles equipped with other
22 than pneumatic tires shall be operated, unladen or with load,
23 upon the highways of this State when the gross weight on the
24 road surface through any wheel thereof exceeds 800 pounds per
25 inch width of tire tread or when the gross weight on the road
26 surface through any axle thereof exceeds 16,000 pounds. An
27 axle load shall be defined as the total load transmitted to
28 the road by all wheels whose centers may be included between
29 2 parallel transverse vertical planes 40 inches apart
30 extending across the full width of the vehicle.
31 Any 2 or more single axles whose centers are more than 40
-2- LRB9005058NTsb
1 inches and not more than 96 inches apart, measured to the
2 nearest inch between extreme axles in the series, shall be
3 defined as tandem axles, and the gross weight transmitted to
4 the road surface through the series shall not exceed 32,000
5 pounds and no axle of the series shall exceed the maximum
6 weight permitted under this Section for a single axle.
7 Provided that on a 4 axle vehicle or on a 5 or more axle
8 combination of vehicles the weight on a series of 3 axles
9 whose centers are more than 96 inches apart, measured between
10 extreme axles in the series, shall not exceed those allowed
11 on 3 axles in the table contained in subsection (f) of this
12 Section and no axle or tandem axle of the series shall exceed
13 the maximum weight permitted under this Section for a single
14 or tandem axle. Provided also that a 3 axle vehicle or 3 axle
15 truck mixer registered as a Special Hauling Vehicle, used

10 permit by ordinance axle loads on 2 axle motor vehicles 33
11 1/2% above those provided for herein, but the increase shall
12 not become effective until the city has officially notified
13 the Department of the passage of the ordinance and shall not
14 apply to those vehicles when outside of the limits of the
15 city, nor shall the gross weight of any 2 axle motor vehicle
16 operating over any street of the city exceed 40,000 pounds.
17 (d) Weight limitations shall not apply to vehicles
18 (including loads) operated by a public utility when
19 transporting equipment required for emergency repair of

-6- LRB9005058NTsb
1 license plate must cover the operating empty weight of the
2 tow truck only. The weight of each vehicle being towed shall
3 be covered by a valid license plate issued to the owner or
4 operator of the vehicle being towed and displayed on that
5 vehicle. If no valid plate issued to the owner or operator of
6 that vehicle is displayed on that vehicle, or the plate
7 displayed on that vehicle does not cover the weight of the
8 vehicle, the weight of the vehicle shall be covered by the
9 third tow truck plate issued to the owner or operator of the
10 tow truck and temporarily affixed to the vehicle being towed.
11 In addition, the following conditions must be met:
12 (1) the towing vehicle must be:
13 a. specifically designed as a tow truck having
14 a gross vehicle weight rating of at least 18,000
15 lbs. and equipped with air brakes provided that air
16 brakes shall be required only if the towing vehicle
17 is towing a vehicle, semitrailer, or tractor-trailer
18 combination that is equipped with airbrakes;
19 b. equipped with flashing, rotating or
20 oscillating amber lights, visible for at least 500
21 feet in all directions; and
22 c. capable of utilizing the lighting and
23 braking systems of the disabled vehicle or
24 combination of vehicles.
25 (2) The towing of the vehicles on the highways of
26 this State shall not exceed 15 miles from the initial
27 point of wreck or disablement. Any additional movement of
28 the vehicles shall only occur upon issuance of
29 authorization for that movement under the provisions of
30 Sections 15-301 through 15-319 of this Chapter.
31 The Department may by rule or regulation prescribe
32 additional requirements. However, nothing in this Code shall
33 prohibit a tow truck under instructions of a police officer
34 from legally clearing a disabled vehicle, that may be in
-7- LRB9005058NTsb
1 violation of weight limitations of this Chapter, from the
2 roadway to the berm or shoulder of the highway.
3 For the purpose of this subsection, gross vehicle weight
4 rating, or GVWR, shall mean the value specified by the
5 manufacturer as the loaded weight of the tow truck.
6 (e) No vehicle or combination of vehicles equipped with
7 pneumatic tires shall be operated, unladen or with load, upon
8 the highways of this State in violation of the provisions of
9 any permit issued under the provisions of Sections 15-301
10 through 15-319 of this Chapter.
11 (f) Notwithstanding any other provision in this Code,
12 except for those provisions of subsection (d) of this Section
13 relating to emergency operations of public utilities and tow
14 trucks while actually engaged in the towing of a disabled
15 vehicle, and those vehicles for which the Department issues
16 overweight permits under authority of Section 15-301 of this
17 Code, the weight limitations contained in this subsection
18 shall apply to the National System of Interstate and Defense
19 Highways and other highways in the system of State highways
20 that have been designated by the Department as Class I, II,
21 or III. No vehicle shall be operated on the highways with a
22 weight in excess of 20,000 pounds carried on any one axle or
23 with a tandem axle weight in excess of 40,000 34,000 pounds,
24 or a gross weight in excess of 80,000 pounds for vehicle
25 combinations of 5 axles or more, or a gross weight on a group
26 of 2 or more consecutive axles in excess of that weight
27 produced by the application of the following formula:
28 W = 500 times the sum of (LN divided by N-1) + 12N + 36
29 Where "W" equals overall gross weight on any group of 2 or
30 more consecutive axles to the nearest 500 pounds; "L" equals
31 the distance measured to the nearest foot between extremes of
32 any group of 2 or more consecutive axles; and "N" equals the
33 number of axles in the group under consideration, except that
34 2 consecutive sets of tandem axles may carry a gross load of
-8- LRB9005058NTsb
1 40,000 34,000 pounds each, provided the overall distance
2 between the first and last axles of the consecutive sets of
3 tandem axles is 36 feet or more and provided that the gross
4 weight for vehicle combinations of 5 axles or more does not
5 exceed 80,000 pounds. Provided also that a 3-axle vehicle
6 registered as a Special Hauling Vehicle manufactured prior to
7 or in the model year of 2004, and first registered in
8 Illinois prior to January 1, 2005, with a distance greater
9 than 72 inches but not more than 96 inches between the 2 rear
10 axles may transmit to the road surface a maximum weight of
11 18,000 pounds on each of the 2 rear axles with a gross weight
12 on these 2 axles not to exceed 36,000 pounds. Any vehicle
13 registered as a Special Hauling Vehicle manufactured prior to
14 or in the model year of 2004 or thereafter or first
15 registered in Illinois after December 31, 2004, may transmit
16 to the road surface a maximum of 34,000 pounds through the 2
17 rear axles and neither of the rear axles shall exceed 20,000
18 pounds. For purposes of this subsection, tandem axles shall
19 be defined as any 2 or more single axles whose centers are
20 more than 40 inches and not more than 96 inches apart,
21 measured to the nearest inch between extreme axles in the
22 series.
23 The above formula when expressed in tabular form results
24 in allowable loads as follows:

23 *If the distance between 2 axles is 96 inches or less, the 2
24 axles are tandem axles and the maximum load permitted is
25 40,000 34,000 pounds, notwithstanding the lower higher limit
26 resulting from the application of the formula.
27 In applying the above formula to a vehicle having more
28 than 4 axles that is not a combination, only 4 axles shall be
29 considered in determining the maximum gross weight, and for a
30 combination of vehicles having more than 6 axles, only 6
31 axles shall be considered in determining the maximum gross
32 weight.
33 Notwithstanding the above table, 2 consecutive sets of
34 tandem axles may carry a gross weight of 40,000 34,000 pounds
-11- LRB9005058NTsb
1 each if the overall distance between the first and last axles
2 of the consecutive sets of tandem axles is 36 feet or more
3 and if the gross weight for vehicle combinations of 5 axles
4 or more does not exceed 80,000 pounds.
5 Local authorities and road district highway
6 commissioners, with respect to streets and highways under
7 their jurisdiction, without additional fees, may also by
8 ordinance or resolution allow the weight limitations of this
9 subsection, provided the maximum gross weight on any one axle
10 shall not exceed 20,000 pounds and the maximum gross weight
11 on any tandem axle shall not exceed 40,000 34,000 pounds, on
12 designated highways when appropriate regulatory signs giving
13 notice are erected upon the street or highway or portion of
14 any street or highway affected by the ordinance or
15 resolution.
16 Combinations of vehicles, registered as Special Hauling
17 Vehicles that include a semitrailer manufactured prior to or
18 in the model year of 2004, and first registered in Illinois
19 prior to January 1, 2005, having 5 axles with a distance of
20 42 feet or less between extreme axles shall be limited to the
21 weights prescribed in subsections (a) and (b) of this Section
22 and not subject to the bridge formula on the National System
23 of Interstate and Defense Highways and other highways in the
24 system of State highways designated by the Department. For
25 all those combinations of vehicles, that include a
26 semitrailer manufactured after the effective date of this
27 amendatory Act of 1986, the overall distance between the
28 first and last axles of the 2 sets of tandems must be 18 feet
29 6 inches or more. All combinations of vehicles registered as
30 Special Hauling Vehicles that include a semitrailer
31 manufactured prior to or in the model year of 2004 or
32 thereafter or first registered in Illinois after December 31,
33 2004, or that has had its cargo container replaced in its
34 entirety after December 31, 2004, are limited to the gross
-12- LRB9005058NTsb
1 weight allowed by the above formula.
2 A truck not in combination, equipped with a self
3 compactor or an industrial roll-off hoist and roll-off
4 container, used exclusively for garbage or refuse operations,
5 shall be allowed the weights as prescribed in subsections (a)
6 and (b) of this Section and not subject to the bridge
7 formula, provided they are not operated on a highway that is
8 part of the Interstate and Defense Highway System.
9 Vehicles operating under this subsection shall have
10 access for a distance of one highway mile to or from a Class
11 I highway on any street or highway, unless there is a sign
12 prohibiting the access, or 5 highway miles to or from either
13 a Class I, II, or III highway on a street or highway included
14 in the system of State highways and upon any street or
15 highway designated by local authorities or road district
16 commissioners to points of loading and unloading and to
17 facilities for food, fuel, repairs and rest.
18 Section 5-35 of the Illinois Administrative Procedure Act
19 relating to procedures for rulemaking shall not apply to the
20 designation of highways under this subsection.
21 (g) No person shall operate a vehicle or combination of
22 vehicles over a bridge or other elevated structure
23 constituting part of a highway with a gross weight that is
24 greater than the maximum weight permitted by the Department,
25 when the structure is sign posted as provided in this
26 Section.
27 (h) The Department upon request from any local authority
28 shall, or upon its own initiative may, conduct an
29 investigation of any bridge or other elevated structure
30 constituting a part of a highway, and if it finds that the
31 structure cannot with safety to itself withstand the weight
32 of vehicles otherwise permissible under this Code the
33 Department shall determine and declare the maximum weight of
34 vehicles that the structures can withstand, and shall cause
-13- LRB9005058NTsb
1 or permit suitable signs stating maximum weight to be erected
2 and maintained before each end of the structure. No person
3 shall operate a vehicle or combination of vehicles over any
4 structure with a gross weight that is greater than the posted
5 maximum weight.
6 (i) Upon the trial of any person charged with a
7 violation of subsections (g) or (h) of this Section, proof of
8 the determination of the maximum allowable weight by the
9 Department and the existence of the signs, constitutes
10 conclusive evidence of the maximum weight that can be
11 maintained with safety to the bridge or structure.
