| Public Act 104-0787 | ||||
| ||||
AN ACT concerning transportation. | ||||
Be it enacted by the People of the State of Illinois, | ||||
represented in the General Assembly: | ||||
Section 5. The Illinois Vehicle Code is amended by | ||||
changing Sections 11-208.8, 11-601, 11-602, and 11-604 and by | ||||
adding Section 1-214.2 as follows: | ||||
(625 ILCS 5/1-214.2 new) | ||||
Sec. 1-214.2. Target speed. The target speed is the | ||||
highest desired operating speed given land-use contexts, | ||||
multimodal activity, and vehicular mobility and shall be | ||||
established by the entity with jurisdiction over that roadway. | ||||
(625 ILCS 5/11-208.8) | ||||
Sec. 11-208.8. Automated speed enforcement systems in | ||||
safety zones. | ||||
(a) As used in this Section: | ||||
"Automated speed enforcement system" means a photographic | ||||
device, radar device, laser device, or other electrical or | ||||
mechanical device or devices installed or utilized in a safety | ||||
zone and designed to record the speed of a vehicle and obtain a | ||||
clear photograph or other recorded image of the vehicle and | ||||
the vehicle's registration plate or digital registration plate | ||||
while the driver is violating Article VI of Chapter 11 of this | ||||
Code or a similar provision of a local ordinance. | ||
An automated speed enforcement system is a system, located | ||
in a safety zone which is under the jurisdiction of a | ||
municipality, that produces a recorded image of a motor | ||
vehicle's violation of a provision of this Code or a local | ||
ordinance and is designed to obtain a clear recorded image of | ||
the vehicle and the vehicle's license plate. The recorded | ||
image must also display the time, date, and location of the | ||
violation. | ||
"Owner" means the person or entity to whom the vehicle is | ||
registered. | ||
"Recorded image" means images recorded by an automated | ||
speed enforcement system on: | ||
(1) 2 or more photographs; | ||
(2) 2 or more microphotographs; | ||
(3) 2 or more electronic images; or | ||
(4) a video recording showing the motor vehicle and, | ||
on at least one image or portion of the recording, clearly | ||
identifying the registration plate or digital registration | ||
plate number of the motor vehicle. | ||
"Safety zone" means an area that is within one-eighth of a | ||
mile from the nearest property line of any public or private | ||
elementary or secondary school, or from the nearest property | ||
line of any facility, area, or land owned by a school district | ||
that is used for educational purposes approved by the Illinois | ||
State Board of Education, not including school district | ||
headquarters or administrative buildings. A safety zone also | ||
includes an area that is within one-eighth of a mile from the | ||
nearest property line of any facility, area, or land owned by a | ||
park district used for recreational purposes. However, if any | ||
portion of a roadway is within either one-eighth mile radius, | ||
the safety zone also shall include the roadway extended to the | ||
furthest portion of the next furthest intersection. The term | ||
"safety zone" does not include any portion of the roadway | ||
known as Lake Shore Drive or any controlled access highway | ||
with 8 or more lanes of traffic or any roadway in which the 30 | ||
mile per hour maximum speed limit is decreased by local | ||
ordinance without an engineering or traffic investigation in | ||
accordance with subsection (b) of Section 11-604 after the | ||
effective date of this amendatory Act of the 104th General | ||
Assembly. | ||
(a-5) The automated speed enforcement system shall be | ||
operational and violations shall be recorded only at the | ||
following times: | ||
(i) if the safety zone is based upon the property line | ||
of any facility, area, or land owned by a school district, | ||
only on school days and no earlier than 6 a.m. and no later | ||
than 8:30 p.m. if the school day is during the period of | ||
Monday through Thursday, or 9 p.m. if the school day is a | ||
Friday; and | ||
(ii) if the safety zone is based upon the property | ||
line of any facility, area, or land owned by a park | ||
district, no earlier than one hour prior to the time that | ||
the facility, area, or land is open to the public or other | ||
patrons, and no later than one hour after the facility, | ||
area, or land is closed to the public or other patrons. | ||
(b) A municipality that produces a recorded image of a | ||
motor vehicle's violation of a provision of this Code or a | ||
local ordinance must make the recorded images of a violation | ||
accessible to the alleged violator by providing the alleged | ||
violator with a website address, accessible through the | ||
Internet. | ||
(c) Notwithstanding any penalties for any other violations | ||
of this Code, the owner of a motor vehicle used in a traffic | ||
violation recorded by an automated speed enforcement system | ||
shall be subject to the following penalties: | ||
(1) if the recorded speed is no less than 6 miles per | ||
hour and no more than 10 miles per hour over the legal | ||
speed limit, a civil penalty not exceeding $50, plus an | ||
additional penalty of not more than $50 for failure to pay | ||
the original penalty in a timely manner; or | ||
(2) if the recorded speed is more than 10 miles per | ||
hour over the legal speed limit, a civil penalty not | ||
exceeding $100, plus an additional penalty of not more | ||
than $100 for failure to pay the original penalty in a | ||
timely manner. | ||
A penalty may not be imposed under this Section if the | ||
driver of the motor vehicle received a Uniform Traffic | ||
Citation from a police officer for a speeding violation | ||
occurring within one-eighth of a mile and 15 minutes of the | ||
violation that was recorded by the system. A violation for | ||
which a civil penalty is imposed under this Section is not a | ||
violation of a traffic regulation governing the movement of | ||
vehicles and may not be recorded on the driving record of the | ||
owner of the vehicle. A law enforcement officer is not | ||
required to be present or to witness the violation. No penalty | ||
may be imposed under this Section if the recorded speed of a | ||
vehicle is 5 miles per hour or less over the legal speed limit. | ||
The municipality may send, in the same manner that notices are | ||
sent under this Section, a speed violation warning notice | ||
where the violation involves a speed of 5 miles per hour or | ||
less above the legal speed limit. | ||
(d) The net proceeds that a municipality receives from | ||
civil penalties imposed under an automated speed enforcement | ||
system, after deducting all non-personnel and personnel costs | ||
associated with the operation and maintenance of such system, | ||
shall be expended or obligated by the municipality for the | ||
following purposes: | ||
(i) public safety initiatives to ensure safe passage | ||
around schools, and to provide police protection and | ||
surveillance around schools and parks, including but not | ||
limited to: (1) personnel costs; and (2) non-personnel | ||
costs such as construction and maintenance of public | ||
safety infrastructure and equipment; | ||
(ii) initiatives to improve pedestrian and traffic | ||
safety; | ||
(iii) construction and maintenance of infrastructure | ||
within the municipality, including but not limited to | ||
roads and bridges; and | ||
(iv) after school programs. | ||
(e) For each violation of a provision of this Code or a | ||
local ordinance recorded by an automated speed enforcement | ||
system, the municipality having jurisdiction shall issue a | ||
written notice of the violation to the registered owner of the | ||
vehicle as the alleged violator. The notice shall be delivered | ||
to the registered owner of the vehicle, by mail, within 30 days | ||
after the Secretary of State notifies the municipality of the | ||
identity of the owner of the vehicle, but in no event later | ||
than 90 days after the violation. | ||
(f) The notice required under subsection (e) of this | ||
Section shall include: | ||
(1) the name and address of the registered owner of | ||
the vehicle; | ||
(2) the registration number of the motor vehicle | ||
involved in the violation; | ||
(3) the violation charged; | ||
(4) the date, time, and location where the violation | ||
occurred; | ||
(5) a copy of the recorded image or images; | ||
(6) the amount of the civil penalty imposed and the | ||
date by which the civil penalty should be paid; | ||
(7) a statement that recorded images are evidence of a | ||
violation of a speed restriction; | ||
(8) a warning that failure to pay the civil penalty or | ||
to contest liability in a timely manner is an admission of | ||
liability; | ||
(9) a statement that the person may elect to proceed | ||
by: | ||
(A) paying the fine; or | ||
(B) challenging the charge in court, by mail, or | ||
by administrative hearing; and | ||
(10) a website address, accessible through the | ||
Internet, where the person may view the recorded images of | ||
the violation. | ||
(g) (Blank). | ||
(h) Based on inspection of recorded images produced by an | ||
automated speed enforcement system, a notice alleging that the | ||
violation occurred shall be evidence of the facts contained in | ||
the notice and admissible in any proceeding alleging a | ||
violation under this Section. | ||
(i) Recorded images made by an automated speed enforcement | ||
system are confidential and shall be made available only to | ||
the alleged violator and governmental and law enforcement | ||
agencies for purposes of adjudicating a violation of this | ||
Section, for statistical purposes, or for other governmental | ||
purposes. Any recorded image evidencing a violation of this | ||
Section, however, may be admissible in any proceeding | ||
resulting from the issuance of the citation. | ||
(j) The court or hearing officer may consider in defense | ||
of a violation: | ||
(1) that the motor vehicle or registration plates or | ||
digital registration plates of the motor vehicle were | ||
stolen before the violation occurred and not under the | ||
control or in the possession of the owner or lessee at the | ||
time of the violation; | ||
(1.5) that the motor vehicle was hijacked before the | ||
violation occurred and not under the control of or in the | ||
possession of the owner or lessee at the time of the | ||
violation; | ||
(2) that the driver of the motor vehicle received a | ||
Uniform Traffic Citation from a police officer for a | ||
speeding violation occurring within one-eighth of a mile | ||
and 15 minutes of the violation that was recorded by the | ||
system; and | ||
(3) any other evidence or issues provided by municipal | ||
ordinance. | ||
(k) To demonstrate that the motor vehicle was hijacked or | ||
the motor vehicle or registration plates or digital | ||
registration plates were stolen before the violation occurred | ||
and were not under the control or possession of the owner or | ||
lessee at the time of the violation, the owner or lessee must | ||
submit proof that a report concerning the motor vehicle or | ||
registration plates was filed with a law enforcement agency in | ||
a timely manner. | ||
(l) A roadway equipped with an automated speed enforcement | ||
system shall be posted with a sign conforming to the national | ||
Manual on Uniform Traffic Control Devices that is visible to | ||
approaching traffic stating that vehicle speeds are being | ||
photo-enforced and indicating the speed limit. The | ||
municipality shall install such additional signage as it | ||
determines is necessary to give reasonable notice to drivers | ||
as to where automated speed enforcement systems are installed. | ||
(m) A roadway where a new automated speed enforcement | ||
system is installed shall be posted with signs providing 30 | ||
days notice of the use of a new automated speed enforcement | ||
system prior to the issuance of any citations through the | ||
automated speed enforcement system. | ||
(n) The compensation paid for an automated speed | ||
enforcement system must be based on the value of the equipment | ||
or the services provided and may not be based on the number of | ||
traffic citations issued or the revenue generated by the | ||
system. | ||
(n-1) No member of the General Assembly and no officer or | ||
employee of a municipality or county shall knowingly accept | ||
employment or receive compensation or fees for services from a | ||
vendor that provides automated speed enforcement system | ||
equipment or services to municipalities or counties. No former | ||
member of the General Assembly shall, within a period of 2 | ||
years immediately after the termination of service as a member | ||
of the General Assembly, knowingly accept employment or | ||
receive compensation or fees for services from a vendor that | ||
provides automated speed enforcement system equipment or | ||
services to municipalities or counties. No former officer or | ||
employee of a municipality or county shall, within a period of | ||
2 years immediately after the termination of municipal or | ||
county employment, knowingly accept employment or receive | ||
compensation or fees for services from a vendor that provides | ||
automated speed enforcement system equipment or services to | ||
municipalities or counties. | ||
(o) (Blank). | ||
(p) No person who is the lessor of a motor vehicle pursuant | ||
to a written lease agreement shall be liable for an automated | ||
speed or traffic law enforcement system violation involving | ||
such motor vehicle during the period of the lease; provided | ||
that upon the request of the appropriate authority received | ||
within 120 days after the violation occurred, the lessor | ||
provides within 60 days after such receipt the name and | ||
address of the lessee. The drivers license number of a lessee | ||
may be subsequently individually requested by the appropriate | ||
authority if needed for enforcement of this Section. | ||
Upon the provision of information by the lessor pursuant | ||
to this subsection, the municipality may issue the violation | ||
to the lessee of the vehicle in the same manner as it would | ||
issue a violation to a registered owner of a vehicle pursuant | ||
to this Section, and the lessee may be held liable for the | ||
violation. | ||
(q) A municipality using an automated speed enforcement | ||
system must provide notice to drivers by publishing the | ||
locations of all safety zones where system equipment is | ||
installed on the website of the municipality. | ||
(r) A municipality operating an automated speed | ||
enforcement system shall conduct a statistical analysis to | ||
assess the safety impact of the system following installation | ||
of the system and every 2 years thereafter. A municipality | ||
operating an automated speed enforcement system before the | ||
effective date of this amendatory Act of the 103rd General | ||
Assembly shall conduct a statistical analysis to assess the | ||
safety impact of the system by no later than one year after the | ||
effective date of this amendatory Act of the 103rd General | ||
Assembly and every 2 years thereafter. Each statistical | ||
analysis shall be based upon the best available crash, | ||
traffic, and other data, and shall cover a period of time | ||
before and after installation of the system sufficient to | ||
provide a statistically valid comparison of safety impact. | ||
Each statistical analysis shall be consistent with | ||
professional judgment and acceptable industry practice. Each | ||
statistical analysis also shall be consistent with the data | ||
required for valid comparisons of before and after conditions | ||
and shall be conducted within a reasonable period following | ||
the installation of the automated traffic law enforcement | ||
system. Each statistical analysis required by this subsection | ||
shall be made available to the public and shall be published on | ||
the website of the municipality. | ||
(s) This Section applies only to municipalities with a | ||
population of 1,000,000 or more inhabitants. | ||
(t) If a county or municipality selects a new vendor for | ||
its automated speed enforcement system and must, as a | ||
consequence, apply for a permit, approval, or other | ||
authorization from the Department for reinstallation of one or | ||
more malfunctioning components of that system and if, at the | ||
time of the application for the permit, approval, or other | ||
authorization, the new vendor operates an automated speed | ||
enforcement system for any other county or municipality in the | ||
State, then the Department shall approve or deny the county or | ||
municipality's application for the permit, approval, or other | ||
authorization within 90 days after its receipt. | ||
(u) The Department may revoke any permit, approval, or | ||
other authorization granted to a county or municipality for | ||
the placement, installation, or operation of an automated | ||
speed enforcement system if any official or employee who | ||
serves that county or municipality is charged with bribery, | ||
official misconduct, or a similar crime related to the | ||
placement, installation, or operation of the automated speed | ||
enforcement system in the county or municipality. | ||
The Department shall adopt any rules necessary to | ||
implement and administer this subsection. The rules adopted by | ||
the Department shall describe the revocation process, shall | ||
ensure that notice of the revocation is provided, and shall | ||
provide an opportunity to appeal the revocation. Any county or | ||
municipality that has a permit, approval, or other | ||
authorization revoked under this subsection may not reapply | ||
for such a permit, approval, or other authorization for a | ||
period of 1 year after the revocation. | ||
(v) The University of Illinois Chicago Urban | ||
Transportation Center shall conduct a study that includes the | ||
following: | ||
(1) a comprehensive review of the City of Chicago's | ||
website multi-year crash data on North and South DuSable | ||
Lake Shore Drive; | ||
(2) the available research on potential effectiveness | ||
of cameras powered by artificial intelligence in improving | ||
compliance and reducing crashes and road fatalities on | ||
North and South DuSable Lake Shore Drive; | ||
(3) an analysis of driving behavior to detect risky | ||
driving patterns and to address the DuSable Lake Shore | ||
Drive crash corridors; | ||
(4) an assessment of the effectiveness of | ||
psychological deterrence in reducing habitual speeding; | ||
and | ||
(5) an assessment of how fatalities can be reduced | ||
using these cameras powered by artificial intelligence and | ||
other technical options that may be available in place of | ||
cameras powered by artificial intelligence. | ||
The Department shall adopt any rules necessary to | ||
implement this subsection (v). | ||

(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, | ||
bicyclists, 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. | ||
(a-5) For purposes of this Section, "urban district" does | ||
not include any interstate highway as defined by Section | ||
1-133.1 of this Code which includes all highways under the | ||
jurisdiction of the Illinois State Toll Highway Authority. | ||
(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 is (1) 65 miles per hour 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. | ||
(d-1) Unless some other speed restriction is established | ||
under this Chapter, the maximum speed limit outside an urban | ||
district for any vehicle is (1) 70 miles per hour on any | ||
interstate highway as defined by Section 1-133.1 of this Code | ||
which includes all highways under the jurisdiction of the | ||
Illinois State Toll Highway Authority; (2) 65 miles per hour | ||
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 (3) 55 miles per hour for all other highways, roads, and | ||
streets. The counties of Cook, DuPage, Kane, Lake, Madison, | ||
McHenry, St. Clair, and Will may adopt ordinances setting a | ||
maximum speed limit on highways, roads, and streets that is | ||
lower than the limits established by this Section. | ||
(e) In the counties of Cook, DuPage, Kane, Lake, McHenry, | ||
and Will, 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 60 | ||
miles per hour on any interstate highway as defined by Section | ||
1-133.1 of this Code and 55 miles per hour on all other | ||
highways, roads, and streets. | ||
(e-1) (Blank). | ||
(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; | ||
1.5. 70 miles per hour upon any interstate highway as | ||
defined by Section 1-133.1 of this Code outside the | ||
counties of Cook, DuPage, Kane, Lake, McHenry, and Will; | ||
and | ||
2. 55 miles per hour on any other highway. | ||

(625 ILCS 5/11-602) (from Ch. 95 1/2, par. 11-602) | ||
Sec. 11-602. Alteration of limits by Department. | ||
(a) 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 conform with the maximum | ||
speed limit restrictions provided for in Section 11-601 of | ||
this Code. | ||
(b) Where any highway under the Department's jurisdiction | ||
lies within the jurisdictional boundary of a local authority, | ||
the Department may, at the local authority's request or by its | ||
own initiative, set a reduced maximum speed limit upon the | ||
basis of an engineering and traffic investigation. If the | ||
highway falls within an urban district and if the local | ||
authority's request or Department initiative is to decrease | ||
the maximum speed limit to 25 miles per hour, the reduction may | ||
occur without performing an engineering and traffic | ||
investigation if the reduction aligns with the determined | ||
target speed, as defined in Section 1-214.2, for that portion | ||
of the highway. | ||
(c) 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. | ||
(d) 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 5/11-604) (from Ch. 95 1/2, par. 11-604) | ||
Sec. 11-604. Alteration of limits by local authorities. | ||
(a) 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. | ||
(b) 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, | ||
which shall not require an engineering or traffic | ||
investigation to a maximum speed limit of 25 miles per | ||
hour, but not to less than 20 miles per hour and a maximum | ||
speed limit of 10 miles per hour in an alley; 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, | ||
which shall not require an engineering or traffic | ||
investigation to a maximum speed limit of 20 , but not to | ||
less than 25 miles per hour, except as otherwise provided | ||
in paragraph (1) 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 shall be posted with signs | ||
designating the new speed limit and 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. | ||
(b-1) A county, municipality, or township may request that | ||
the Department perform an engineering and traffic | ||
investigation concerning any portion of highway under the | ||
Department's jurisdiction, which lies within the geographic | ||
boundary of the requesting local authority, to determine a | ||
reasonable or safe absolute maximum speed limit for that | ||
portion of highway. The Department shall perform the | ||
engineering and traffic investigation and report the results | ||
to the requesting local authority unless otherwise specified | ||
in Section 11-602. | ||
(c) 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. | ||
(d) 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. Upon receipt of an engineering study | ||
for the part or zone of highway in question from the county | ||
engineer, and notwithstanding any other provision of law, the | ||
county board of a county may determine and declare by | ||
ordinance a reduction in the maximum speed limit at any place | ||
or along any part or zone of a county highway whenever the | ||
county board, in its sole discretion, determines that the | ||
reduction in the maximum speed limit is reasonable and safe. | ||
The county board shall may post signs designating the new | ||
speed limit. 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. | ||
