Illinois General Assembly - Illinois Compiled Statutes

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.

(625 ILCS 5/15-316) (from Ch. 95 1/2, par. 15-316)

Sec. 15-316. When the Department or local authority may restrict right to use highways.

(a) Except as provided in subsection (g), local authorities with
respect to highways under their jurisdiction may by ordinance or resolution
prohibit the operation of vehicles upon any such highway or impose
restrictions as to the weight of vehicles to be operated upon any such
highway, for a total period of not to exceed 90 days, measured in either consecutive or nonconsecutive days at the discretion of local authorities, in any one calendar
year, whenever any said highway by reason of deterioration, rain, snow, or
other climate conditions will be seriously damaged or destroyed unless the
use of vehicles thereon is prohibited or the permissible weights thereof
reduced.

(b) The local authority
enacting any such ordinance or resolution shall erect or cause to be erected
and maintained signs designating the provision of the ordinance or resolution
at each end of that portion of any highway affected thereby, and the ordinance
or resolution shall not be effective unless and until such signs are erected
and maintained. To be effective, an ordinance or resolution passed to designate a Class II roadway need not require that signs be erected, but the designation shall be reported to the Department.

(c) Local authorities with
respect to highways under their jurisdiction may also, by ordinance or
resolution, prohibit the operation of trucks or other commercial vehicles,
or may impose limitations as the weight thereof, on designated highways, which
prohibitions and limitations shall be designated by appropriate signs placed on
such highways.

(c-1) (Blank).

(c-5) Highway commissioners, with respect to roads under their authority, may not permanently post a road or portion thereof at a reduced weight limit unless the decision to do so is made in accordance with Section 6-201.22 of the Illinois Highway Code.

(d) The Department shall likewise have authority as hereinbefore
granted to local authorities to
determine by resolution and to impose restrictions as to the weight of vehicles
operated upon any highway under the jurisdiction of said department, and such
restrictions shall be effective when signs giving notice thereof are erected
upon the highway or portion of any highway affected by such resolution.

(d-1) (Blank).

(d-2) (Blank).

(e) When any vehicle is operated in violation of this Section, the owner
or driver of the vehicle shall be deemed guilty of a violation and either the
owner or the driver of the vehicle may be prosecuted for the violation.  Any
person, firm, or corporation convicted of violating this Section shall be fined
$50 for any weight exceeding the posted limit up to the axle or gross weight
limit allowed a vehicle as provided for in subsections (a) or (b) of Section
15-111 and $75 per every 500 pounds or fraction thereof for any weight
exceeding that which is provided for in subsections (a) or
(b) of Section 15-111.

(f) A municipality is authorized to enforce a county weight limit
ordinance applying to county highways within its corporate limits and is
entitled to the proceeds of any fines collected from the enforcement.

(g) An ordinance or resolution enacted by a county or township pursuant to subsection (a) of this Section shall not apply to cargo tank vehicles with two or three permanent axles when delivering propane for emergency heating purposes if the cargo tank is loaded at no more than 50 percent capacity, the gross vehicle weight of the vehicle does not exceed 32,000 pounds, and the driver of the cargo tank vehicle notifies the appropriate agency or agencies with jurisdiction over the highway before driving the vehicle on the highway pursuant to this subsection. The cargo tank vehicle must have an operating gauge on the cargo tank which indicates the amount of propane as a percent of capacity of the cargo tank. The cargo tank must have  the capacity  displayed on the cargo tank, or documentation of the capacity of the cargo tank must be available in the vehicle. For the purposes of this subsection, propane weighs 4.2 pounds per gallon. This subsection does not apply to municipalities. Nothing in this subsection shall allow cargo tank
vehicles
to cross bridges with posted weight restrictions if the vehicle exceeds the posted weight limit.
