(625 ILCS 5/Ch. 11 Art. VI heading) ARTICLE VI. SPEED RESTRICTIONS

    (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 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. 
    (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 of the first division or
a second division vehicle designed or used for the carrying of a gross weight of 8,000
pounds or less (including the weight of the vehicle and maximum load) is (1) 65 miles
per hour (i) for all highways under the jurisdiction of the Illinois State Toll
Highway Authority and (ii) 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. 
    (e) 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 55 miles per hour. 
    (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; and
        2. 60 miles per hour on any other highway, 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.
    (g) Unless some other speed restriction is established under this Chapter, the
maximum speed limit outside an urban district for a house car, camper, private living
coach, vehicles licensed as recreational vehicles, and any vehicle towing any other
vehicle is 55 miles per hour or the posted speed limit, whichever is less.
