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:
|
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1 | Distance measured
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
2 | to the nearest
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3 | foot between the
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 | extremes of any Maximum weight in pounds
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
5 | group of 2 or of any group of
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
6 | more consecutive 2 or more consecutive axles
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
7 | axles
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
12 | *If the distance between 2 axles is 96 inches or less, the 2 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
13 | axles are
tandem axles and the maximum total weight may not | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
14 | exceed 34,000 pounds,
notwithstanding the higher limit | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
15 | resulting from the application of the formula.
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
16 | Vehicles not in a combination having more than 4 axles may | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
17 | not exceed the
weight in the table in this subsection (a) for 4 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
18 | axles measured between the
extreme axles of the
vehicle.
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
19 | Vehicles in a combination having more than 6 axles may not | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
20 | exceed the weight
in the table in this subsection (a) for 6 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
21 | axles measured between the extreme
axles of the
combination.
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
22 | Local authorities, with respect
to streets and highways | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
23 | under their jurisdiction, without additional
fees, may also by | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
24 | ordinance or resolution allow the weight limitations of this
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
25 | subsection, provided the maximum gross weight on any one axle | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
26 | shall not exceed
20,000 pounds and the maximum total weight on |
| |||||||
| |||||||
1 | any tandem axle
shall not exceed
34,000 pounds, on designated | ||||||
2 | highways when appropriate regulatory signs giving
notice are | ||||||
3 | erected upon the street or highway or portion of any street or
| ||||||
4 | highway affected by the ordinance or resolution.
| ||||||
5 | The following are exceptions to the above formula:

to the bridge formula.
| ||||||
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.

| ||||||
7 | not subject
to the bridge formula. For all those | ||||||
8 | combinations of vehicles that include a
semitrailer | ||||||
9 | manufactured after the effective date of P.A. 92-0417, the | ||||||
10 | overall distance between the first and last
axles of the 2 | ||||||
11 | sets of
tandems must be 18 feet 6 inches or
more. Any | ||||||
12 | combination of vehicles that has had its cargo
container | ||||||
13 | replaced in its entirety after December 31, 2024 2014 may | ||||||
14 | not
exceed
the weights allowed by the bridge formula. | ||||||
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 |
| |||||||
| |||||||
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 |
| |||||||
| |||||||
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, |
| |||||||
| |||||||
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 |
| |||||||
| |||||||
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.
