6adding Section 1-214.2 as follows:
7    (625 ILCS 5/1-214.2 new)
8    Sec. 1-214.2. Target speed. The target speed is the 
9highest desired operating speed given land-use contexts, 
10multimodal activity, and vehicular mobility and shall be 
11established by the entity with jurisdiction over that roadway.
12    (625 ILCS 5/11-208.8)
13    Sec. 11-208.8. Automated speed enforcement systems in
14safety zones.
15    (a) As used in this Section:
16    "Automated speed enforcement system" means a photographic
17device, radar device, laser device, or other electrical or
18mechanical device or devices installed or utilized in a safety
19zone and designed to record the speed of a vehicle and obtain a
20clear photograph or other recorded image of the vehicle and
21the vehicle's registration plate or digital registration plate
22while the driver is violating Article VI of Chapter 11 of this
		HB5081 Enrolled	- 2 -	LRB104 19977 LNS 33428 b
1Code or a similar provision of a local ordinance.
2    An automated speed enforcement system is a system, located
3in a safety zone which is under the jurisdiction of a
4municipality, that produces a recorded image of a motor
5vehicle's violation of a provision of this Code or a local
6ordinance and is designed to obtain a clear recorded image of
7the vehicle and the vehicle's license plate. The recorded
8image must also display the time, date, and location of the
9violation.
10    "Owner" means the person or entity to whom the vehicle is
11registered.
12    "Recorded image" means images recorded by an automated
13speed enforcement system on:
14        (1) 2 or more photographs;
15        (2) 2 or more microphotographs;
16        (3) 2 or more electronic images; or
17        (4) a video recording showing the motor vehicle and,
18    on at least one image or portion of the recording, clearly
19    identifying the registration plate or digital registration
20    plate number of the motor vehicle.
21    "Safety zone" means an area that is within one-eighth of a
22mile from the nearest property line of any public or private
23elementary or secondary school, or from the nearest property
24line of any facility, area, or land owned by a school district
25that is used for educational purposes approved by the Illinois
26State Board of Education, not including school district
		HB5081 Enrolled	- 3 -	LRB104 19977 LNS 33428 b
1headquarters or administrative buildings. A safety zone also
2includes an area that is within one-eighth of a mile from the
3nearest property line of any facility, area, or land owned by a
4park district used for recreational purposes. However, if any
5portion of a roadway is within either one-eighth mile radius,
6the safety zone also shall include the roadway extended to the
7furthest portion of the next furthest intersection. The term
8"safety zone" does not include any portion of the roadway
9known as Lake Shore Drive or any controlled access highway
10with 8 or more lanes of traffic or any roadway in which the 30 
11mile per hour maximum speed limit is decreased by local 
12ordinance without an engineering or traffic investigation in 
13accordance with subsection (b) of Section 11-604 after the 
14effective date of this amendatory Act of the 104th General 
15Assembly.
16    (a-5) The automated speed enforcement system shall be
17operational and violations shall be recorded only at the
18following times:
19        (i) if the safety zone is based upon the property line
20    of any facility, area, or land owned by a school district,
21    only on school days and no earlier than 6 a.m. and no later
22    than 8:30 p.m. if the school day is during the period of
23    Monday through Thursday, or 9 p.m. if the school day is a
24    Friday; and
25        (ii) if the safety zone is based upon the property
26    line of any facility, area, or land owned by a park
		HB5081 Enrolled	- 4 -	LRB104 19977 LNS 33428 b
1    district, no earlier than one hour prior to the time that
2    the facility, area, or land is open to the public or other
3    patrons, and no later than one hour after the facility,
4    area, or land is closed to the public or other patrons.
5    (b) A municipality that produces a recorded image of a
6motor vehicle's violation of a provision of this Code or a
7local ordinance must make the recorded images of a violation
8accessible to the alleged violator by providing the alleged
9violator with a website address, accessible through the
10Internet.
11    (c) Notwithstanding any penalties for any other violations
12of this Code, the owner of a motor vehicle used in a traffic
13violation recorded by an automated speed enforcement system
14shall be subject to the following penalties:
15        (1) if the recorded speed is no less than 6 miles per
16    hour and no more than 10 miles per hour over the legal
17    speed limit, a civil penalty not exceeding $50, plus an
18    additional penalty of not more than $50 for failure to pay
19    the original penalty in a timely manner; or
20        (2) if the recorded speed is more than 10 miles per
21    hour over the legal speed limit, a civil penalty not
22    exceeding $100, plus an additional penalty of not more
23    than $100 for failure to pay the original penalty in a
24    timely manner.
25    A penalty may not be imposed under this Section if the
26driver of the motor vehicle received a Uniform Traffic
		HB5081 Enrolled	- 5 -	LRB104 19977 LNS 33428 b
1Citation from a police officer for a speeding violation
2occurring within one-eighth of a mile and 15 minutes of the
3violation that was recorded by the system. A violation for
4which a civil penalty is imposed under this Section is not a
5violation of a traffic regulation governing the movement of
6vehicles and may not be recorded on the driving record of the
7owner of the vehicle. A law enforcement officer is not
8required to be present or to witness the violation. No penalty
9may be imposed under this Section if the recorded speed of a
10vehicle is 5 miles per hour or less over the legal speed limit.
11The municipality may send, in the same manner that notices are
12sent under this Section, a speed violation warning notice
13where the violation involves a speed of 5 miles per hour or
14less above the legal speed limit.
15    (d) The net proceeds that a municipality receives from
16civil penalties imposed under an automated speed enforcement
17system, after deducting all non-personnel and personnel costs

3        (iii) construction and maintenance of infrastructure
4    within the municipality, including but not limited to
5    roads and bridges; and
6        (iv) after school programs.
7    (e) For each violation of a provision of this Code or a
8local ordinance recorded by an automated speed enforcement
9system, the municipality having jurisdiction shall issue a
10written notice of the violation to the registered owner of the
11vehicle as the alleged violator. The notice shall be delivered
12to the registered owner of the vehicle, by mail, within 30 days
13after the Secretary of State notifies the municipality of the
14identity of the owner of the vehicle, but in no event later
15than 90 days after the violation.

2        (7) a statement that recorded images are evidence of a
3    violation of a speed restriction;
4        (8) a warning that failure to pay the civil penalty or
5    to contest liability in a timely manner is an admission of
6    liability;
7        (9) a statement that the person may elect to proceed
8    by:
9            (A) paying the fine; or

10    Sec. 11-602. Alteration of limits by Department.
11    (a) Whenever the Department determines, upon the basis of
12an engineering and traffic investigation concerning any
13highway for which the Department has maintenance
14responsibility, that a maximum speed limit prescribed in
15Section 11-601 of this Chapter is greater or less than is
16reasonable or safe with respect to the conditions found to
17exist at any intersection or other place on such highway or
18along any part or zone thereof, the Department shall determine
19and declare a reasonable and safe absolute maximum speed limit
20applicable to such intersection or place, or along such part
21or zone. However, such limit shall conform with the maximum
22speed limit restrictions provided for in Section 11-601 of
23this Code.
24    (b) Where any highway under the Department's jurisdiction 
25lies within the jurisdictional boundary of a local authority, 
		HB5081 Enrolled	- 18 -	LRB104 19977 LNS 33428 b
1the Department may, at the local authority's request or by its 
2own initiative, set a reduced maximum speed limit upon the 
3basis of an engineering and traffic investigation. If the 
4highway falls within an urban district and if the local 
5authority's request or Department initiative is to decrease 
6the maximum speed limit to 25 miles per hour, the reduction may 
7occur without performing an engineering and traffic 
8investigation if the reduction aligns with the determined 
9target speed, as defined in Section 1-214.2, for that portion 
10of the highway.
11    (c) Where a highway under the Department's jurisdiction is
12contiguous to school property, the Department may, at the
13school district's request, set a reduced maximum speed limit
14for student safety purposes in the portion of the highway that
15faces the school property and in the portions of the highway
16that extend one-quarter mile in each direction from the
17opposite ends of the school property.
18    (d) A limit determined and declared as provided in this
19Section becomes effective, and suspends the applicability of
20the limit prescribed in Section 11-601 of this Chapter, when
21appropriate signs giving notice of the limit are erected at
22such intersection or other place, or along such part or zone of
23the highway. Electronic speed-detecting devices shall not be
24used within 500 feet beyond any such sign in the direction of
25travel; if so used in violation hereof, evidence obtained
26thereby shall be inadmissible in any prosecution for speeding.
		HB5081 Enrolled	- 19 -	LRB104 19977 LNS 33428 b
1However, nothing in this Section prohibits the use of such
2electronic speed-detecting devices within 500 feet of a sign
3within a special school speed zone indicating such zone,
4conforming to the requirements of Section 11-605 of this Act,
5nor shall evidence obtained thereby be inadmissible in any
6prosecution for speeding provided the use of such device shall
7apply only to the enforcement of the speed limit in such
8special school speed zone.

10    (625 ILCS 5/11-604)  (from Ch. 95 1/2, par. 11-604)
11    Sec. 11-604. Alteration of limits by local authorities.
12    (a) Subject to the limitations set forth in this Section,
13the county board of a county may establish absolute maximum
14speed limits on all county highways, township roads and
15district roads as defined in the Illinois Highway Code, except
16those under the jurisdiction of the Department or of the
17Illinois State Toll Highway Authority, as described in
18Sections 11-602 and 11-603 of this Chapter; and any park
19district, city, village, or incorporated town may establish
20absolute maximum speed limits on all streets which are within
21its corporate limits and which are not under the jurisdiction
22of the Department or of such Authority, and for which the
23county or a highway commissioner of such county does not have
24maintenance responsibility.
25    (b) Whenever any such park district, city, village, or
		HB5081 Enrolled	- 20 -	LRB104 19977 LNS 33428 b
1incorporated town determines, upon the basis of an engineering
2or traffic investigation concerning a highway or street on
3which it is authorized by this Section to establish speed
4limits, that a maximum speed limit prescribed in Section
511-601 of this Chapter is greater or less than is reasonable or
6safe with respect to the conditions found to exist at any place
7or along any part or zone of such highway or street, the local
8authority or park district shall determine and declare by
9ordinance a reasonable and safe absolute maximum speed limit
10at such place or along such part or zone, which:
11        (1) Decreases the limit within an urban district, 
12    which shall not require an engineering or traffic 
13    investigation to a maximum speed limit of 25 miles per 
14    hour, but not [to] less than 20 miles per hour and a maximum 
15    speed limit of 10 miles per hour in an alley; or
16        (2) Increases the limit within an urban district, but
17    not to more than 55 miles per hour; or
18        (3) Decreases the limit outside of an urban district,
19    but not to less than 35 miles per hour, except as otherwise
20    provided in subparagraph 4 of this paragraph; or
21        (4) Decreases the limit within a residence district, 
22    which shall not require an engineering or traffic 
23    investigation to a maximum speed limit of 20 [, but not to ]
24    [less than 25] miles per hour, except as otherwise provided
25    in paragraph (1) [subparagraph 1 of this paragraph].
26    The park district, city, village, or incorporated town may
		HB5081 Enrolled	- 21 -	LRB104 19977 LNS 33428 b
1make such limit applicable at all times or only during certain
2specified times. Not more than 6 such alterations shall be
3made per mile along a highway or street; and the difference in
4limit between adjacent altered speed zones shall not be more
5than 10 miles per hour.
6    A limit so determined and declared by a park district,
7city, village, or incorporated town shall be posted with signs 
8designating the new speed limit and becomes effective, and
9suspends the application of the limit prescribed in Section
1011-601 of this Chapter, when appropriate signs giving notice
11of the limit are erected at the proper place or along the
12proper part or zone of the highway or street. Electronic
13speed-detecting devices shall not be used within 500 feet
14beyond any such sign in the direction of travel; if so used in
15violation of this Section evidence obtained thereby shall be
16inadmissible in any prosecution for speeding. However, nothing
17in this Section prohibits the use of such electronic
18speed-detecting devices within 500 feet of a sign within a
19special school speed zone indicating such zone, conforming to
20the requirements of Section 11-605 of this Act, nor shall
21evidence obtained thereby be inadmissible in any prosecution
22for speeding provided the use of such device shall apply only
23to the enforcement of the speed limit in such special school
24speed zone.
25    (b-1) A county, municipality, or township may request that 
26the Department perform an engineering and traffic 
		HB5081 Enrolled	- 22 -	LRB104 19977 LNS 33428 b
1investigation concerning any portion of highway under the 
2Department's jurisdiction, which lies within the geographic 
3boundary of the requesting local authority, to determine a 
4reasonable or safe absolute maximum speed limit for that 
5portion of highway. The Department shall perform the 
6engineering and traffic investigation and report the results 
7to the requesting local authority unless otherwise specified 
8in Section 11-602.
9    (c) A county engineer or superintendent of highways may
10submit to the Department for approval, a county policy for
11establishing altered speed zones on township and county
12highways based upon engineering and traffic investigations.
13    (d) Whenever the county board of a county determines that
14a maximum speed limit is greater or less than is reasonable or
15safe with respect to the conditions found to exist at any place
16or along any part or zone of the highway or road, the county
17board shall determine and declare by ordinance a reasonable
18and safe absolute maximum speed limit at that place or along
19that part or zone. However, the maximum speed limit shall not
20exceed 55 miles per hour. Upon receipt of an engineering study
21for the part or zone of highway in question from the county
22engineer, and notwithstanding any other provision of law, the
23county board of a county may determine and declare by
24ordinance a reduction in the maximum speed limit at any place
25or along any part or zone of a county highway whenever the
26county board, in its sole discretion, determines that the
		HB5081 Enrolled	- 23 -	LRB104 19977 LNS 33428 b
1reduction in the maximum speed limit is reasonable and safe.
2The county board shall [may] post signs designating the new
3speed limit. The limit becomes effective, and suspends the
4application of the limit prescribed in Section 11-601 of this
5Chapter, when appropriate signs giving notice of the limit are
6erected at the proper place or along the proper part of the
7zone of the highway. Electronic speed-detecting devices shall
8not be used within 500 feet beyond any such sign in the
9direction of travel; if so used in violation of this Section,
10evidence obtained thereby shall be inadmissible in any
11prosecution for speeding. However, nothing in this Section
12prohibits the use of such electronic speed-detecting devices
13within 500 feet of a sign within a special school speed zone
14indicating such zone, conforming to the requirements of
15Section 11-605 of this Act, nor shall evidence obtained
16thereby be inadmissible in any prosecution for speeding
17provided the use of such device shall apply only to the
18enforcement of the speed limit in such special school speed
19zone.
