22 allowed a maximum gross weight listed in the table of
23 subsection (f) of this Section for 4 axles. This vehicle is not
24 subject to the series of 3 axles requirement provided for in
25 subdivision (a)(11) of this Section.
26     (c) Cities having a population of more than 50,000 may
27 permit by ordinance axle loads on 2 axle motor vehicles 33 1/2%
28 above those provided for herein, but the increase shall not
29 become effective until the city has officially notified the
30 Department of the passage of the ordinance and shall not apply
31 to those vehicles when outside of the limits of the city, nor
32 shall the gross weight of any 2 axle motor vehicle operating

HB4457 Engrossed - 6 - LRB093 19159 DRH 44894 b

1 over any street of the city exceed 40,000 pounds.
2     (d) Weight limitations shall not apply to vehicles
3 (including loads) operated by a public utility when
4 transporting equipment required for emergency repair of public
5 utility facilities or properties or water wells.
6     A combination of vehicles, including a tow truck and a
7 disabled vehicle or disabled combination of vehicles, that
8 exceeds the weight restriction imposed by this Code, may be
9 operated on a public highway in this State provided that
10 neither the disabled vehicle nor any vehicle being towed nor
11 the tow truck itself shall exceed the weight limitations
12 permitted under this Chapter. During the towing operation,
13 neither the tow truck nor the vehicle combination shall exceed
14 24,000 pounds on a single rear axle and 44,000 pounds on a
15 tandem rear axle, provided the towing vehicle:
16         (1) is specifically designed as a tow truck having a
17 gross vehicle weight rating of at least 18,000 pounds and
18 is equipped with air brakes, provided that air brakes are
19 required only if the towing vehicle is towing a vehicle,
20 semitrailer, or tractor-trailer combination that is
21 equipped with air brakes;
22         (2) is equipped with flashing, rotating, or
23 oscillating amber lights, visible for at least 500 feet in
24 all directions;
25         (3) is capable of utilizing the lighting and braking
26 systems of the disabled vehicle or combination of vehicles;
27 and
28         (4) does not engage in a tow exceeding 20 miles from
29 the initial point of wreck or disablement. Any additional
30 movement of the vehicles may occur only upon issuance of
31 authorization for that movement under the provisions of
32 Sections 15-301 through 15-319 of this Code.
33     Gross weight limits shall not apply to the combination of
34 the tow truck and vehicles being towed. The tow truck license
35 plate must cover the operating empty weight of the tow truck
36 only. The weight of each vehicle being towed shall be covered

HB4457 Engrossed - 7 - LRB093 19159 DRH 44894 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.
9     The Department may by rule or regulation prescribe
10 additional requirements. However, nothing in this Code shall
11 prohibit a tow truck under instructions of a police officer
12 from legally clearing a disabled vehicle, that may be in
13 violation of weight limitations of this Chapter, from the
14 roadway to the berm or shoulder of the highway. If in the
15 opinion of the police officer that location is unsafe, the
16 officer is authorized to have the disabled vehicle towed to the
17 nearest place of safety.
18     For the purpose of this subsection, gross vehicle weight
19 rating, or GVWR, shall mean the value specified by the
20 manufacturer as the loaded weight of the tow truck.
21     (e) No vehicle or combination of vehicles equipped with
22 pneumatic tires shall be operated, unladen or with load, upon
23 the highways of this State in violation of the provisions of
24 any permit issued under the provisions of Sections 15-301
25 through 15-319 of this Chapter.
26     (f) On designated Class I, II, or III highways and the
27 National System of Interstate and Defense Highways, no vehicle
28 or combination of vehicles with pneumatic tires may be
29 operated, unladen or with load, when the total weight on the
30 road surface exceeds the following: 20,000 pounds on a single
31 axle; 34,000 pounds on a tandem axle with no axle within the
32 tandem exceeding 20,000 pounds; 80,000 pounds gross weight for
33 vehicle combinations of 5 or more axles; or a total weight on a
34 group of 2 or more consecutive axles in excess of that weight
35 produced by the application of the following formula: W = 500
36 times the sum of (LN divided by N-1) + 12N + 36, where "W"

HB4457 Engrossed - 8 - LRB093 19159 DRH 44894 b

1 equals overall total weight on any group of 2 or more
2 consecutive axles to the nearest 500 pounds, "L" equals the
3 distance measured to the nearest foot between extremes of any
4 group of 2 or more consecutive axles, and "N" equals the number
5 of axles in the group under consideration.
6     The above formula when expressed in tabular form results in
7 allowable loads as follows:

12 subsection, provided the maximum gross weight on any one axle
13 shall not exceed 20,000 pounds and the maximum total weight on
