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.

Special limit while traveling through a highway construction or maintenance speed zone.
(a) A person may not operate a motor vehicle in a construction or maintenance speed zone at a speed in excess of the posted speed limit when workers are present.
(a-5) A person may not operate a motor vehicle in a construction or maintenance speed zone at a speed in excess of the posted speed limit when workers are not present.
(b) Nothing in this Chapter prohibits the use of electronic speed-detecting devices within 500 feet of signs within a construction or maintenance speed zone indicating the zone, as defined in this Section, nor shall evidence obtained by use of those devices be inadmissible in any prosecution for speeding, provided the use of the device shall apply only to the enforcement of the speed limit in the construction or maintenance speed zone.
(c) As used in this Section, a "construction or maintenance speed zone" is an area in which the Department, Toll Highway Authority, or local agency has posted signage advising drivers that a construction or maintenance speed zone is being approached, or in which the Department, Authority, or local agency has posted a lower speed limit with a highway construction or maintenance speed zone special speed limit sign after determining that the preexisting established speed limit through a highway construction or maintenance project is greater than is reasonable or safe with respect to the conditions expected to exist in the construction or maintenance speed zone.
If it is determined that the preexisting established speed limit is safe with respect to the conditions expected to exist in the construction or maintenance speed zone, additional speed limit signs which conform to the requirements of this subsection (c) shall be posted.
Highway construction or maintenance speed zone special speed limit signs shall be of a design approved by the Department. The signs must give proper due warning that a construction or maintenance speed zone is being approached and must indicate the maximum speed limit in effect. The signs also must state the amount of the minimum fine for a violation.
(d) Except as provided under subsection (d-5), a person who violates this Section is guilty of a petty offense. Violations of this Section are punishable with a minimum fine of $250 for the first violation and a minimum fine of $750 for the second or subsequent violation.
(d-5) A person committing a violation of this Section is guilty of aggravated special speed limit while traveling through a highway construction or maintenance speed zone when he or she drives a motor vehicle at a speed that is:
(1) 26 miles per hour or more but less than 35 miles
per hour in excess of the applicable special speed limit established under this Section or a similar provision of a local ordinance and is guilty of a Class B misdemeanor; or
(2) 35 miles per hour or more in excess of the
applicable special speed limit established under this Section or a similar provision of a local ordinance and is guilty of a Class A misdemeanor.
(e-5) The Department of State Police and the local county police department have concurrent jurisdiction over any violation of this Section that occurs on an interstate highway.
(f) The Transportation Safety Highway Hire-back Fund, which was created by Public Act 92-619, shall continue to be a special fund in the State treasury. Subject to appropriation by the General Assembly and approval by the Secretary, the Secretary of Transportation shall use all moneys in the Transportation Safety Highway Hire-back Fund to hire off-duty Department of State Police officers to monitor construction or maintenance zones.
(f-5) Each county shall create a Transportation Safety Highway Hire-back Fund. The county shall use the moneys in its Transportation Safety Highway Hire-back Fund to hire off-duty county police officers to monitor construction or maintenance zones in that county on highways other than interstate highways. The county, in its discretion, may also use a portion of the moneys in its Transportation Safety Highway Hire-back Fund to purchase equipment for county law enforcement and fund the production of materials to educate drivers on construction zone safe driving habits.
(g) For a second or subsequent violation of this Section within 2 years of the date of the previous violation, the Secretary of State shall suspend the driver's license of the violator for a period of 90 days.
This suspension shall only be
imposed if the current violation of this Section and at least one prior violation of this Section
occurred during a period when workers were present in the
construction or maintenance zone.

upon the basis of an engineering and traffic investigation concerning a
highway or street under its jurisdiction that slow vehicle speeds along
any part or zone of such highway or street consistently impede the normal
and reasonable movement of traffic, the Department, the Toll Highway Authority,
or local authority (as appropriate) may determine and declare by proper
regulation or ordinance a minimum speed
limit below which no person shall drive except when necessary for safe operation
of his vehicle or in compliance with law. A limit so determined and declared
becomes effective when appropriate signs giving notice of the limit are
erected along such part or zone of the highway or street.

(from Ch. 95 1/2, par. 11-707)
(a) The Department and local authorities
are authorized to determine those portions of any highway under their
respective jurisdictions where overtaking and passing or driving on the
left of the roadway would be especially hazardous and may by appropriate
signs or markings on the roadway indicate the beginning and end of such
zones. Upon request of a local school board, the Department or local
authority which has jurisdiction over the roadway in question, shall
determine whether a hazardous situation exists at a particular location and
warrants a no-passing zone. If the Department or local authority
determines that a no-passing zone is warranted, the school board and the
Department or local authority shall share equally the cost of designating
the no-passing zone by signs and markings. When such signs or markings are
in place and clearly visible to an ordinarily observant person every driver
of a vehicle shall obey the directions thereof.
(b) Where signs or markings are in place to define a no-passing zone as
set forth in paragraph (a) no driver may at any time drive on the left side
of the roadway within the no-passing zone or on the left side of any pavement
striping designed to mark such no-passing zone throughout its length.
(c) This Section does not apply under the conditions described in
Section 11-701 (a) 2, subsection (d-5) of Section 11-703, nor to the driver of a vehicle turning left into or from
an alley, private road or driveway. The pavement striping designed to mark
the no-passing zone may be crossed from the left hand lane for the
purpose of completing a pass that was begun prior to the beginning of the
zone in the driver's direction of travel.

Driving on roadways laned for traffic.
Whenever any roadway has been divided into 2 or more clearly marked
lanes for traffic the following rules in addition to all others consistent
herewith shall apply.
(a) A vehicle shall be driven as nearly as practicable entirely within a
single lane and shall not be moved from such lane until the driver has
first ascertained that such movement can be made with safety.
(b) Upon a roadway which is divided into 3 lanes and provides for
two-way movement of traffic, a vehicle shall not be driven in the center
lane except when overtaking and passing another vehicle traveling in the
same direction when such center lane is clear of traffic within a safe
distance, or in preparation for making a left turn or where such center
lane is at the time allocated exclusively to traffic moving in the same
direction that the vehicle is proceeding and such allocation is designated
by official traffic control devices.
(c) Official traffic control devices may be erected directing specific
traffic to use a designated lane or designating those lanes to be used by
traffic moving in a particular direction regardless of the center of the
roadway and drivers of vehicles shall obey the directions of every such
device. On multi-lane controlled access
highways with 3 or more lanes in one
direction or on any multi-laned highway with 2 or more lanes in one
direction, the Department may designate lanes of traffic to be used by
different types of motor vehicles.
Drivers must obey lane designation signing except when it is necessary to
use a different lane to make a turning maneuver.
(d) Official traffic control devices may be installed prohibiting the
changing of lanes on sections of roadway and drivers of vehicles shall obey
the directions of every such device.
(e) A person is not in violation of this Section if he or she is complying with Section 11-907, 11-907.5, or 11-908.
