    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 
Section 11-604 as follows:
 



    (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, 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.
    (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 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.
