(625 ILCS 5/Ch. 11 Art. VI heading) ARTICLE VI. SPEED RESTRICTIONS
(625 ILCS 5/11‑601)(from Ch. 95 1/2, par. 11‑601) Sec. 11‑601. General speed restrictions. (a) No vehicle may be driven upon any highway of this State at a speed
which is greater than is reasonable and proper with regard to traffic
conditions and the use of the highway, or endangers the safety of any
person or property. The fact that the speed of a vehicle does not exceed
the applicable maximum speed limit does not relieve the driver from the
duty to decrease speed when approaching and crossing an intersection,
approaching and going around a curve, when approaching a hill crest, when
traveling upon any narrow or winding roadway, or when special hazard exists
with respect to pedestrians or other traffic or by reason of weather or
highway conditions. Speed must be decreased as may be necessary to avoid
colliding with any person or vehicle on or entering the highway in
compliance with legal requirements and the duty of all persons to use due
care. (b) No person may drive a vehicle upon any highway of this State at a
speed which is greater than the applicable statutory maximum speed limit
established by paragraphs (c), (d), (e), (f) or (g) of this Section, by
Section 11‑605 or by a regulation or ordinance made under this Chapter. (c) Unless some other speed restriction is established under this
Chapter, the maximum speed limit in an urban district for all vehicles is: 1. 30 miles per hour; and 2. 15 miles per hour in an alley. (d) Unless some other speed restriction is established under this Chapter,
the maximum speed limit outside an urban district for any vehicle of the
first division or a second division vehicle
designed or used for
the carrying of a gross weight of 8,000 pounds or less
(including the
weight of the vehicle and maximum load) is (1) 65 miles per hour (i) for
all highways under the jurisdiction of the Illinois State Toll
Highway Authority and (ii) for all or part of highways that are designated by
the Department, have at least 4 lanes of traffic, and have a separation between
the roadways moving in opposite directions and (2) 55 miles per hour for all
other highways, roads, and streets. (e) Unless some lesser speed restriction is established under
this
Chapter, the maximum speed limit outside an urban district for a second
division vehicle designed or used for the carrying of a gross weight of
8,001 pounds or more (including the weight of the vehicle and
maximum load) is
55 miles per hour. (f) Unless some other speed restriction is established under this Chapter,
the maximum speed limit outside an urban district for a bus is: 1. 65 miles per hour upon any highway which has at
least 4 lanes of traffic and of which the roadways for traffic moving in opposite directions are separated by a strip of ground which is not surfaced or suitable for vehicular traffic, except that the maximum speed limit for a bus on all highways, roads, or streets not under the jurisdiction of the Department or the Illinois State Toll Highway Authority is 55 miles per hour; and
2. 60 miles per hour on any other highway, except
that the maximum speed limit for a bus on all highways, roads, or streets not under the jurisdiction of the Department or the Illinois State Toll Highway Authority is 55 miles per hour.
(g) Unless some other speed restriction is established under this Chapter,
the maximum speed limit outside an urban district for a house car, camper,
private living coach, vehicles licensed as recreational vehicles, and any
vehicle towing any other vehicle is 55 miles per hour or the posted speed
limit, whichever is less. (Source: P.A. 89‑444, eff. 1‑25‑96; 89‑551, eff. 1‑1‑97.)
(625 ILCS 5/11‑601.5) Sec. 11‑601.5. Driving 40 miles per hour or more in excess of
applicable limit. A person who drives a vehicle upon any highway of
this State at a speed that is 40 miles per hour or more in excess of
the applicable maximum speed limit established under this Chapter or a
local ordinance commits a Class A misdemeanor. (Source: P.A. 91‑469, eff. 1‑1‑00.)
(625 ILCS 5/11‑602)(from Ch. 95 1/2, par. 11‑602) Sec. 11‑602. Alteration of limits by Department. Whenever the Department
determines,
upon the basis of an engineering and traffic investigation concerning any
highway for which the Department has maintenance responsibility, that a
maximum speed limit prescribed in Section 11‑601 of this Chapter is greater
or less than is reasonable or safe with respect to the conditions found
to exist at any intersection or other place on such highway or along any
part or zone thereof, the Department shall determine and declare a reasonable
and safe absolute maximum speed limit applicable to such intersection or
place, or along such part or zone. However, such limit shall not exceed
65 miles per hour, or 55 miles per hour for a second division vehicle designed
or used for the carrying of a gross weight of
8,001
pounds or more (including the weight of the vehicle and maximum load), on a
highway or street which is especially
designed for
through traffic and to, from, or over which owners of or persons having
an interest in abutting property or other persons have no right or easement,
or only a limited right or easement, of access, crossing, light, air, or
view, and shall not exceed 55 miles per hour on any other highway. Where
a highway under the Department's jurisdiction
is contiguous to school property, the Department may, at the school district's
request, set a
reduced maximum speed limit for student safety purposes in the portion of the
highway that faces the school property and in the portions of the highway that
extend
one‑quarter mile in each direction from the opposite ends of the school
property. A limit determined and
declared as provided in this Section becomes effective, and suspends the
applicability of the limit
prescribed
in Section 11‑601 of this Chapter, when appropriate signs giving notice
of the limit are erected at such intersection or other
place, or along such part or zone of the highway. Electronic
speed‑detecting devices shall not be used within 500 feet beyond any such
sign in the direction of travel; if so used in violation hereof, evidence
obtained thereby shall be inadmissible in any prosecution for speeding.
However, nothing in this Section prohibits the use of such electronic
speed‑detecting devices within 500 feet of a sign within a special
school speed zone indicating such zone, conforming to the requirements of
Section 11‑605 of this Act, nor shall evidence obtained thereby be
inadmissible in any prosecution for speeding provided the use of such
device shall apply only to the enforcement of the speed limit in such
special school speed zone.

(625 ILCS 5/11‑603)(from Ch. 95 1/2, par. 11‑603) Sec. 11‑603. Alteration of limits by Toll Highway Authority.
Whenever the Illinois State Toll Highway Authority
determines, upon the basis of an
engineering and traffic investigation concerning a toll highway under its
jurisdiction, that a maximum speed limit prescribed in Section 11‑601 of
this Chapter is greater or less than is reasonable or safe with respect to
conditions found to exist at any place or along any part or zone of such
highway, the Authority shall determine and declare by regulation a
reasonable and safe absolute maximum speed limit at such place or along
such part or zone, not exceeding 65 miles per hour. A limit so determined
and declared becomes effective, and suspends the application of the limit
prescribed in Section 11‑601 of this Chapter, when (a) the Department
concurs in writing with the Authority's regulation, and (b) appropriate
signs giving notice of the limit are erected at such place or along such
part or zone of the highway. Electronic speed‑detecting devices shall not
be used within 500 feet beyond any such sign in the direction of travel; if
so used in violation hereof, evidence obtained thereby shall be
inadmissible in any prosecution for speeding. (Source: P.A. 89‑444, eff. 1‑25‑96.)
(625 ILCS 5/11‑604)(from Ch. 95 1/2, par. 11‑604) Sec. 11‑604. Alteration of limits by local authorities. Subject to
the limitations set forth in this Section, the county board of a county
may establish absolute maximum speed limits on all county highways,
township roads and district roads as defined in the Illinois Highway
Code, except those under the jurisdiction
of the Department or of the Illinois State Toll Highway Authority, as
described in Sections 11‑602 and 11‑603 of this Chapter; and any park
district, city, village, or incorporated town may establish absolute
maximum speed limits on all streets which are within its corporate
limits and which are not under the jurisdiction of the Department or of
such Authority, and for which the county or a highway commissioner of
such county does not have maintenance responsibility. Whenever any such park district, city, village, or
incorporated town determines, upon
the basis of an engineering or traffic investigation concerning a
highway or street on which it is authorized by this Section to establish
speed limits, that a maximum speed limit prescribed in Section 11‑601 of
this Chapter is greater or less than is reasonable or safe with respect
to the conditions found to exist at any place or along any part or zone
of such highway or street, the local authority or park district shall
determine and declare by ordinance a reasonable and safe absolute
maximum speed limit at such place or along such part or zone,
which: (1) Decreases the limit within an urban district,
but not to less than 20 miles per hour; or
(2) Increases the limit within an urban district,
but not to more than 55 miles per hour; or
(3) Decreases the limit outside of an urban
district, but not to less than 35 miles per hour, except as otherwise provided in subparagraph 4 of this paragraph; or
(4) Decreases the limit within a residence district,
but not to less than 25 miles per hour, except as otherwise provided in subparagraph 1 of this paragraph.
The park district, city, village, or incorporated
town may make such limit applicable
at all times or only during certain specified times. Not more than 6
such alterations shall be made per mile along a highway or street; and
the difference in limit between adjacent altered speed zones shall not
be more than 10 miles per hour. A limit so determined and declared by a park district, city, village,
or incorporated town becomes effective, and suspends the application of
the limit prescribed in Section 11‑601 of this Chapter, when appropriate
signs giving notice of the limit are erected at the proper place or
along the proper part or zone of the highway or street. Electronic
speed‑detecting devices shall not be used within 500 feet beyond any
such sign in the direction of travel; if so used in violation of this
Section evidence obtained thereby shall be inadmissible in any
prosecution for speeding. However, nothing in this Section prohibits
the use of such electronic speed‑detecting devices within 500 feet of a
sign within a special school speed zone indicating such zone, conforming
to the requirements of Section 11‑605 of this Act, nor shall evidence
obtained thereby be inadmissible in any prosecution for speeding
provided the use of such device shall apply only to the enforcement of
the speed limit in such special school speed zone. A county engineer or
superintendent of highways may submit to the Department for approval, a
county policy for establishing altered speed zones on township and county
highways based upon engineering and traffic investigations. Whenever the county board of a county determines that a maximum speed limit
is greater or less than is
reasonable or safe with respect to the conditions found to exist at any place
or along any part or zone of the highway or road, the county board shall
determine and declare by ordinance a reasonable and safe absolute maximum speed
limit at that place or along that part or zone. However, the maximum speed
limit shall not exceed 55 miles per hour.
The limit becomes effective, and suspends the application of the
limit
prescribed in Section 11‑601 of this Chapter, when appropriate signs
giving notice of the limit are erected at the proper place or along the
proper part of the zone of the highway. Electronic speed‑detecting
devices shall not be used within 500 feet beyond any such sign in the
direction of travel; if so used in violation of this Section, evidence
obtained thereby shall be inadmissible in any prosecution for speeding.
However, nothing in this Section prohibits the use of such electronic
speed‑detecting devices within 500 feet of a sign within a special
school speed zone indicating such zone, conforming to the requirements
of Section 11‑605 of this Act, nor shall evidence obtained thereby be
inadmissible in any prosecution for speeding provided the use of such
device shall apply only to the enforcement of the speed limit in such
special school speed zone. (Source: P.A. 89‑444, eff. 1‑25‑96.)
(625 ILCS 5/11‑605)(from Ch. 95 1/2, par. 11‑605) Sec. 11‑605. Special speed limit while passing schools. (a) For the purpose of this Section, "school" means the following
entities: (1) A public or private primary or secondary school. (2) A primary or secondary school operated by a
religious institution.
(3) A public, private, or religious nursery school. On a school day when school children are present and so close
thereto
that a potential hazard exists because of the close proximity of the motorized
traffic, no person shall drive a motor vehicle at a speed in excess of 20 miles
per hour while passing a school zone or while traveling on a roadway on public
school property or upon any public
thoroughfare where children pass going
to and from school. For the purpose of this Section a school day shall begin at seven ante
meridian and shall conclude at four post meridian. This Section shall not be applicable unless appropriate signs are posted
upon streets and highways under their respective jurisdiction and
maintained by the Department, township, county, park district, city,
village or incorporated town wherein the school zone is located. With regard
to the special speed limit while passing schools, such signs
shall give proper due warning that a school zone is being approached and
shall indicate the school zone and the maximum speed limit in effect during
school days when school children are present. (b) (Blank). (c) Nothing in this Chapter shall
prohibit the use of electronic speed‑detecting devices within 500 feet of
signs within a special school speed zone indicating such zone, as defined
in this Section, nor shall evidence obtained thereby be inadmissible in any
prosecution for speeding provided the use of such device shall apply only
to the enforcement of the speed limit in such special school speed zone. (d) (Blank). (e) A first violation of this Section is a petty
offense with a minimum fine
of $150. A second or subsequent violation of this
Section is a petty offense with a minimum fine of $300. (f) When a fine for a violation of subsection (a) is $150 or greater,
the person who violates subsection (a) shall be charged an additional
$50 to be paid to the unit school
district where the
violation
occurred for school safety purposes. If the violation occurred in a dual
school district,
$25 of the surcharge shall be paid to the elementary school district for school
safety
purposes and $25 of the surcharge shall be paid to the high school district for
school
safety purposes. Notwithstanding any other provision of law, the entire $50
surcharge
shall be paid to the appropriate school district or districts. For purposes of this subsection (f), "school safety purposes" includes the
costs
associated with school zone safety education and
the purchase, installation, and maintenance of caution lights
which are
mounted on school speed zone signs. (g) (Blank). (h) (Blank). (Source: P.A. 92‑242, eff. 1‑1‑02; 92‑619, eff. 1‑1‑03; 92‑780, eff. 8‑6‑02; 93‑955, eff. 8‑19‑04.)
(625 ILCS 5/11‑605.1) Sec. 11‑605.1. 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.
(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 determined 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 and has posted a lower speed limit with a highway construction or maintenance speed zone special speed limit sign. 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) A first violation of this Section is a petty offense with a minimum fine of $250. A second or subsequent violation of this Section is a petty offense with a minimum fine of $750. (e) If a fine for a violation of this Section is $250 or
greater, the person who violated this Section shall be charged an additional $125, which shall be deposited into the Transportation Safety Highway Hire‑back Fund in the State treasury, unless (i) the violation occurred on a highway other than an interstate highway and (ii) a county police officer wrote the ticket for the violation, in which case the $125 shall be deposited into that county's Transportation Safety Highway Hire‑back Fund. In the case of a second or subsequent violation of this Section, if the fine is $750 or greater, the person who violated this Section shall be charged an additional $250, which shall be deposited into the Transportation Safety Highway Hire‑back Fund in the State treasury, unless (i) the violation occurred on a highway other than an interstate highway and (ii) a county police officer wrote the ticket for the violation, in which case the $250 shall be deposited into that county's Transportation Safety Highway Hire‑back Fund.
(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 all 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.
(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.

(1) "Park district" means the following entities:
(A) any park district organized under the Park
District Code;
(B) any park district organized under the Chicago
Park District Act; and
(C) any municipality, county, forest district,
school district, township, or other unit of local government that operates a public recreation department or public recreation facilities that has recreation facilities that are not on land owned by any park district listed in subparagraphs (A) and (B) of this subdivision (a)(1).
(2) "Park zone" means the recreation facilities and
areas on any land owned or operated by a park district that are used for recreational purposes, including but not limited to: parks; playgrounds; swimming pools; hiking trails; bicycle paths; picnic areas; roads and streets; and parking lots.
(3) "Park zone street" means that portion of any
street or intersection under the control of a local unit of government, adjacent to a park zone, where the local unit of government has, by ordinance or resolution, designated and approved the street or intersection as a park zone street. If, before the effective date of this amendatory Act of the 94th General Assembly, a street already had a posted speed limit lower than 20 miles per hour, then the lower limit may be used for that park zone street.
(4) "Safety purposes" means the costs associated
with: park zone safety education; the purchase, installation, and maintenance of signs, roadway painting, and caution lights mounted on park zone signs; and any other expense associated with park zones and park zone streets.
(b) On any day when children are present and within 50 feet of motorized traffic, a person may not drive a motor vehicle at a speed in excess of 20 miles per hour or any lower posted speed while traveling on a park zone street that has been designated for the posted reduced speed.
(c) On any day when children are present and within 50 feet of motorized traffic, any driver traveling on a park zone street who fails to come to a complete stop at a stop sign or red light, including a driver who fails to come to a complete stop at a red light before turning right onto a park zone street, is in violation of this Section.
(d) This Section does not apply unless appropriate signs are posted upon park zone streets maintained by the Department or by the unit of local government in which the park zone is located. With regard to the special speed limit on park zone streets, the signs must give proper due warning that a park zone is being approached and must indicate the maximum speed limit on the park zone street.
(e) A first violation of this Section is a petty offense with a minimum fine of $250. A second or subsequent violation of this Section is a petty offense with a minimum fine of $500.
(f) When a fine for a violation of this Section is imposed, the person who violates this Section shall be charged an additional $50, to be paid to the park district for safety purposes.
(g) The Department shall, within 6 months of the effective date of this amendatory Act of the 94th General Assembly, design a set of standardized traffic signs for park zones and park zone streets, including but not limited to: "park zone", "park zone speed limit", and "warning: approaching a park zone". The design of these signs shall be made available to all units of local government or manufacturers at no charge, except for reproduction and postage. (Source: P.A. 94‑808, eff. 5‑26‑06.)

or block the normal and reasonable movement of traffic except when reduced
speed is necessary for safe operation of his vehicle or in compliance with law. (b) Whenever the Department, The Illinois State Toll Highway Authority,
or a local authority described in Section 11‑604 of this Chapter determines,
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. (Source: P.A. 81‑840.)
(625 ILCS 5/11‑608)(from Ch. 95 1/2, par. 11‑608) Sec. 11‑608. Special speed limitation on elevated structures. (a) No person shall drive a vehicle over any bridge or other
elevated structure constituting a part of a highway at a speed which is
greater than the maximum speed which can be maintained with safety to
such bridge or structure, when such structure is sign posted as provided
in this Section. (b) 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
shall thereupon find that such structure cannot with safety to itself
withstand vehicles traveling at the speed otherwise permissible under
this Chapter, the Department shall determine and declare the maximum
speed of vehicles which such structure can safely withstand, and shall
cause or permit suitable signs stating such maximum speed to be erected
and maintained before each end of such structure. (c) Upon the trial of any person charged with a violation of this
Section proof of the determination of the maximum speed by the
Department and the existence of such signs is conclusive evidence of the
maximum speed which can be maintained with safety to such bridge or
structure. (Source: P.A. 76‑1586.)

any speed regulation in this article the complaint, and
also the summons or notice to appear, shall specify the
speed at which the defendant is alleged to have driven and
the maximum speed applicable within the district or at the location. (b) The provision of this article
declaring maximum speed limitations
shall not be construed to relieve the plaintiff in any
action from the burden of proving negligence on the
part of the defendant as the proximate cause of an accident. (Source: P.A. 79‑1069.)
