Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process.
Recent laws may not yet be included in the ILCS database, but they are found on this site as Public
soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the
Because the statute database is maintained primarily for legislative drafting purposes,
statutory changes are sometimes included in the statute database before they take effect.
If the source note at the end of a Section of the statutes includes a Public Act that has
not yet taken effect, the version of the law that is currently in effect may have already
been removed from the database and you should refer to that Public Act to see the changes
made to the current law.

(from Ch. 95 1/2, par. 11-602)
Alteration of limits by Department.
Whenever the Department
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. 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
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
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.
