AMENDMENT TO HOUSE BILL 5081
AMENDMENT NO. ______. Amend House Bill 5081 by replacing
everything after the enacting clause with the following:
"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:

10400HB5081sam001 - 2 - LRB104 19977 LNS 36899 a
"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

10400HB5081sam001 - 3 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 4 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 5 - LRB104 19977 LNS 36899 a
(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

10400HB5081sam001 - 6 - LRB104 19977 LNS 36899 a
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;

10400HB5081sam001 - 7 - LRB104 19977 LNS 36899 a
(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

10400HB5081sam001 - 8 - LRB104 19977 LNS 36899 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

10400HB5081sam001 - 9 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 10 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 11 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 12 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 13 - LRB104 19977 LNS 36899 a
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

(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

10400HB5081sam001 - 15 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 16 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 17 - LRB104 19977 LNS 36899 a
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.
(g) (Blank).

(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

10400HB5081sam001 - 18 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 19 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 20 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 21 - LRB104 19977 LNS 36899 a
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

10400HB5081sam001 - 22 - LRB104 19977 LNS 36899 a
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.
