Illinois Compiled Statutes
Information maintained by the Legislative Reference Bureau Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide. Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

| | having a gross vehicle weight rating of at least 18,000 pounds and is equipped with air brakes, provided that air brakes are required only if the towing vehicle is towing a vehicle, semitrailer, or tractor-trailer combination that is equipped with air brakes;
|
| (ii) is equipped with flashing, rotating, or
| | oscillating amber lights, visible for at least 500 feet in all directions;
|
| (iii) is capable of utilizing the lighting and
| | braking systems of the disabled vehicle or combination of vehicles; and
|
| (iv) does not engage in a tow exceeding 20 miles
| | from the initial point of wreck or disablement. Any additional movement of the vehicles may occur only upon issuance of authorization for that movement under the provisions of Sections 15-301 through 15-318 of this Code. The towing vehicle, however, may tow any disabled vehicle to a point where repairs are actually to occur. This movement shall be valid only on State routes. The tower must abide by posted bridge weight limits.
|
| (12.5) The vehicle weight limitations in this Section
| | do not apply to a covered heavy duty tow and recovery vehicle. The covered heavy duty tow and recovery vehicle license plate must cover the operating empty weight of the covered heavy duty tow and recovery vehicle only.
|
| (13) Upon and during a declaration of an emergency
| | propane supply disaster by the Governor under Section 7 of the Illinois Emergency Management Agency Act:

| | cargo tank, used exclusively for the transportation of propane or liquefied petroleum gas may, when laden, transmit upon the road surface, except when on part of the National System of Interstate and Defense Highways, the following maximum weights: 22,000 pounds on a single axle; 40,000 pounds on a tandem axle; 40,000 pounds gross weight on a 2-axle vehicle; 54,000 pounds gross weight on a 3-axle vehicle; and
|
| (ii) a truck when in combination with a trailer
| | equipped with a cargo tank used exclusively for the transportation of propane or liquefied petroleum gas may, when laden, transmit upon the road surface, except when on part of the National System of Interstate and Defense Highways, the following maximum weights: 22,000 pounds on a single axle; 40,000 pounds on a tandem axle; 90,000 pounds gross weight on a 5-axle or 6-axle vehicle.
|
| Vehicles operating under this paragraph (13) are not
| | subject to the bridge formula.
|
| (14) A vehicle or combination of vehicles that
| | uses natural gas or propane gas as a motor fuel may exceed the above weight limitations by up to 2,000 pounds, the total allowance is calculated by an amount that is equal to the difference between the weight of the vehicle attributable to the natural gas or propane gas tank and fueling system carried by the vehicle, and the weight of a comparable diesel tank and fueling system. This paragraph (14) shall not allow a vehicle to exceed any posted weight limit on a highway or structure.
|
| (15) An emergency vehicle or fire apparatus that is a
| | vehicle designed to be used under emergency conditions to transport personnel and equipment, and used to support the suppression of fires and mitigation of other hazardous situations on a Class I highway, may not exceed 86,000 pounds gross weight, or any of the following weight allowances:
|
| (i) 24,000 pounds on a single steering axle;
(ii) 33,500 pounds on a single drive axle;
(iii) 62,000 pounds on a tandem axle; or
(iv) 52,000 pounds on a tandem rear drive steer
| | (16) A bus, motor coach, or recreational vehicle may
| | carry a total weight of 24,000 pounds on a single axle, but may not exceed other weight provisions of this Section.
|
| Gross weight limits shall not apply to the combination of the tow truck
and vehicles being towed. The tow truck license plate must cover the
operating empty weight of the tow truck only. The weight
of each vehicle being towed shall be covered by a valid license plate issued to
the owner or operator of the vehicle being towed and displayed on that vehicle.
If no valid plate issued to the owner or operator of that vehicle is displayed
on that vehicle, or the plate displayed on that vehicle does not cover the
weight of the vehicle, the weight of the vehicle shall be covered by
the third tow truck plate issued to the owner or operator of the tow truck and
temporarily affixed to the vehicle being towed. If a roll-back carrier is registered and being used as a tow truck, however, the license plate or plates for the tow truck must cover the gross vehicle weight, including any load carried on the bed of the roll-back carrier.
The Department may by rule or regulation prescribe additional requirements.
However, nothing in this Code shall prohibit a tow truck under
instructions of a police officer from legally clearing a disabled vehicle,
that may be in violation of weight limitations of this Chapter, from the
roadway to the berm or shoulder of the highway.
If in the opinion of the police officer that location is unsafe, the officer
is authorized to have the disabled vehicle towed to the nearest place of
safety.
For the purpose of this subsection, gross vehicle weight rating, or
GVWR, means the value specified by the manufacturer as the loaded
weight of the tow truck.
(b) As used in this Section, "recycling haul" or "recycling operation" means the hauling of non-hazardous, non-special, non-putrescible materials, such as paper, glass, cans, or plastic, for subsequent use in the secondary materials market.
(c) No vehicle or combination of vehicles equipped with pneumatic tires
shall be operated, unladen or with load, upon the highways of this State in
violation of the provisions of any permit issued under the provisions of
Sections 15-301 through 15-318 of this Chapter.
(d) No vehicle or combination of vehicles equipped with other than pneumatic
tires may be operated, unladen or with load, upon the highways of this State
when the gross weight on the road surface through any wheel exceeds 800
pounds per inch width of tire tread or when the gross weight on the road
surface through any axle exceeds 16,000 pounds.
(e) No person shall operate a vehicle or combination of vehicles over
a bridge or other elevated structure constituting part of a highway with a
gross weight that is greater than the maximum weight permitted by the
Department, when the structure is sign posted as provided in this Section.
(f) The Department upon request from any local authority shall, or upon
its own initiative may, conduct an investigation of any bridge or other
elevated structure constituting a part of a highway, and if it finds that
the structure cannot with safety to itself withstand the weight of vehicles
otherwise permissible under this Code the Department shall determine and
declare the maximum weight of vehicles that the structures can withstand,
and shall cause or permit suitable signs stating maximum weight to be
erected and maintained before each end of the structure. No person shall
operate a vehicle or combination of vehicles over any structure with a
gross weight that is greater than the posted maximum weight.
(g) Upon the trial of any person charged with a violation of subsection
(e) or (f) of this Section, proof of the determination of the maximum
allowable weight by the Department and the existence of the signs,
constitutes conclusive evidence of the maximum weight that can be
maintained with safety to the bridge or structure.
