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 | |||||||||||||||||||
11 | pounds on a single axle; 34,000 pounds on a tandem axle with no | |||||||||||||||||||
12 | axle within the tandem exceeding 20,000 pounds; 80,000 pounds | |||||||||||||||||||
13 | gross weight for vehicle combinations of 5 or more axles; or a | |||||||||||||||||||
14 | total weight on a group of 2 or more consecutive axles in | |||||||||||||||||||
15 | excess of that weight produced by the application of the | |||||||||||||||||||
16 | following formula: W = 500 times the sum of (LN divided by N-1) | |||||||||||||||||||
17 | + 12N + 36, where "W" equals overall total weight on any group | |||||||||||||||||||
18 | of 2 or more consecutive axles to the nearest 500 pounds, "L" | |||||||||||||||||||
19 | equals the distance measured to the nearest foot between | |||||||||||||||||||
20 | extremes of any group of 2 or more consecutive axles, and "N" | |||||||||||||||||||
21 | equals the number of axles in the group under consideration. | |||||||||||||||||||
22 | The above formula when expressed in tabular form results | |||||||||||||||||||
23 | in allowable loads as follows: |
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1 | Distance measured

14 | *If the distance between 2 axles is 96 inches or less, the 2 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
15 | axles are tandem axles and the maximum total weight may not | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
16 | exceed 34,000 pounds, notwithstanding the higher limit | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
17 | resulting from the application of the formula. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
18 | **Two consecutive sets of tandem axles may carry 34,000 pounds | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
19 | each if the overall distance between the first and last axles | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
20 | of these tandems is 36 feet or more. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
21 | Vehicles not in a combination having more than 4 axles may | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
22 | not exceed the weight in the table in this subsection (a) for 4 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
23 | axles measured between the extreme axles of the vehicle. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
24 | Vehicles in a combination having more than 6 axles may not | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

17 | These vehicles are not subject to the bridge formula. | ||||||
18 | (3) Cities having a population of more than 50,000 may | ||||||
19 | permit by ordinance axle loads on 2-axle motor vehicles 33 | ||||||
20 | 1/2% above those provided for herein, but the increase | ||||||
21 | shall not become effective until the city has officially | ||||||
22 | notified the Department of the passage of the ordinance | ||||||
23 | and shall not apply to those vehicles when outside of the | ||||||
24 | limits of the city, nor shall the gross weight of any | ||||||

3 | transportation of propane or liquefied petroleum gas | ||||||
4 | may, when laden, transmit upon the road surface, | ||||||
5 | except when on part of the National System of | ||||||
6 | Interstate and Defense Highways, the following maximum | ||||||
7 | weights: 22,000 pounds on a single axle; 40,000 pounds | ||||||
8 | on a tandem axle; 90,000 pounds gross weight on a | ||||||
9 | 5-axle or 6-axle vehicle. | ||||||
10 | Vehicles operating under this paragraph (13) are not | ||||||
11 | subject to the bridge formula. | ||||||
12 | (14) A vehicle or combination of vehicles that uses | ||||||
13 | natural gas or propane gas as a motor fuel may exceed the | ||||||
14 | above weight limitations by up to 2,000 pounds, the total | ||||||
15 | allowance is calculated by an amount that is equal to the | ||||||
16 | difference between the weight of the vehicle attributable | ||||||
17 | to the natural gas or propane gas tank and fueling system | ||||||
18 | carried by the vehicle, and the weight of a comparable | ||||||
19 | diesel tank and fueling system. This paragraph (14) shall | ||||||
20 | not allow a vehicle to exceed any posted weight limit on a | ||||||
21 | highway or structure. | ||||||
22 | (15) An emergency vehicle or fire apparatus that is a | ||||||
23 | vehicle designed to be used under emergency conditions to | ||||||
24 | transport personnel and equipment, and used to support the | ||||||
25 | suppression of fires and mitigation of other hazardous | ||||||
26 | situations on a Class I highway, may not exceed 86,000 |
| |||||||
| |||||||
1 | pounds gross weight, or any of the following weight | ||||||
2 | allowances: | ||||||
3 | (i) 24,000 pounds on a single steering axle; | ||||||
4 | (ii) 33,500 pounds on a single drive axle; | ||||||
5 | (iii) 62,000 pounds on a tandem axle; or | ||||||
6 | (iv) 52,000 pounds on a tandem rear drive steer | ||||||
7 | axle. | ||||||
8 | (16) A bus, motor coach, or recreational vehicle may | ||||||
9 | carry a total weight of 24,000 pounds on a single axle, but | ||||||
10 | may not exceed other weight provisions of this Section. | ||||||
11 | (17) A vehicle or combination of vehicles that uses | ||||||
12 | alternative fuel, including, but not limited to, natural | ||||||
13 | gas or propane gas, as a motor fuel or is operated by an | ||||||
14 | engine fueled wholly or partially by an electric battery | ||||||
15 | or hydrogen fuel cell electric fueling system may exceed | ||||||
16 | the above weight limitations by up to 2,000 pounds between | ||||||
17 | the westernmost end of West 143rd Street and west of South | ||||||
18 | Van Dyke Road on West 143rd Street in the Village of | ||||||
19 | Plainfield. This paragraph (17) shall not allow a vehicle | ||||||
20 | to exceed any posted weight limit on a highway or | ||||||
21 | structure. | ||||||
22 | Gross weight limits shall not apply to the combination of | ||||||
23 | the tow truck and vehicles being towed. The tow truck license | ||||||
24 | plate must cover the operating empty weight of the tow truck | ||||||
25 | only. The weight of each vehicle being towed shall be covered | ||||||
26 | by a valid license plate issued to the owner or operator of the |
| |||||||
| |||||||
1 | vehicle being towed and displayed on that vehicle. If no valid | ||||||
2 | plate issued to the owner or operator of that vehicle is | ||||||
3 | displayed on that vehicle, or the plate displayed on that | ||||||
4 | vehicle does not cover the weight of the vehicle, the weight of | ||||||
5 | the vehicle shall be covered by the third tow truck plate | ||||||
6 | issued to the owner or operator of the tow truck and | ||||||
7 | temporarily affixed to the vehicle being towed. If a roll-back | ||||||
8 | carrier is registered and being used as a tow truck, however, | ||||||
9 | the license plate or plates for the tow truck must cover the | ||||||
10 | gross vehicle weight, including any load carried on the bed of | ||||||
11 | the roll-back carrier. | ||||||
12 | The Department may by rule or regulation prescribe | ||||||
13 | additional requirements. However, nothing in this Code shall | ||||||
14 | prohibit a tow truck under instructions of a police officer | ||||||
15 | from legally clearing a disabled vehicle, that may be in | ||||||
16 | violation of weight limitations of this Chapter, from the | ||||||
17 | roadway to the berm or shoulder of the highway. If in the | ||||||
18 | opinion of the police officer that location is unsafe, the | ||||||
19 | officer is authorized to have the disabled vehicle towed to | ||||||
20 | the nearest place of safety. | ||||||
21 | For the purpose of this subsection, gross vehicle weight | ||||||
22 | rating, or GVWR, means the value specified by the manufacturer | ||||||
23 | as the loaded weight of the tow truck. | ||||||
24 | (b) As used in this Section, "recycling haul" or | ||||||
25 | "recycling operation" means the hauling of non-hazardous, | ||||||
26 | non-special, non-putrescible materials, such as paper, glass, |
| |||||||
| |||||||
1 | cans, or plastic, for subsequent use in the secondary | ||||||
2 | 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 15-318 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 | ||||||
16 | constituting part of a highway with a gross weight that is | ||||||
17 | greater than the maximum weight permitted by the Department, | ||||||
18 | when the structure 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 | ||||||
21 | investigation of any bridge or other elevated structure | ||||||
22 | constituting a part of a highway, and if it finds that the | ||||||
23 | structure cannot with safety to itself withstand the weight of | ||||||
24 | vehicles otherwise permissible under this Code the Department | ||||||
25 | shall determine and declare the maximum weight of vehicles | ||||||
26 | that the structures can withstand, and shall cause or permit |
| |||||||
| |||||||
1 | suitable signs stating maximum weight to be erected and | ||||||
2 | maintained before each end of the structure. No person shall | ||||||
3 | 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 | (g) Upon the trial of any person charged with a violation | ||||||
7 | of subsection (e) or (f) of this Section, proof of the | ||||||
8 | 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. | ||||||
