Illinois Compiled Statutes
Information maintained by the Legislative Reference Bureau
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 Acts
soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide
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.

center of the roadway for use by traffic not otherwise permitted to use
such lanes, or except as permitted under Subsection (a) 2. However, this
Subsection shall not be construed as prohibiting the crossing of the center

side is clearly visible and is free of oncoming traffic for a sufficient
distance ahead to permit such overtaking and passing to be completely made
without interfering with the safe operation of any vehicle approaching from

(625 ILCS 5/11-707)
(from Ch. 95 1/2, par. 11-707)
(a) The Department and local authorities
are authorized to determine those portions of any highway under their
respective jurisdictions where overtaking and passing or driving on the
left of the roadway would be especially hazardous and may by appropriate
signs or markings on the roadway indicate the beginning and end of such
zones. Upon request of a local school board, the Department or local
authority which has jurisdiction over the roadway in question, shall
determine whether a hazardous situation exists at a particular location and
warrants a no-passing zone. If the Department or local authority
determines that a no-passing zone is warranted, the school board and the
Department or local authority shall share equally the cost of designating
the no-passing zone by signs and markings. When such signs or markings are
in place and clearly visible to an ordinarily observant person every driver
of a vehicle shall obey the directions thereof.
(b) Where signs or markings are in place to define a no-passing zone as
set forth in paragraph (a) no driver may at any time drive on the left side
of the roadway within the no-passing zone or on the left side of any pavement
striping designed to mark such no-passing zone throughout its length.
(c) This Section does not apply under the conditions described in
Section 11-701 (a) 2, nor to the driver of a vehicle turning left into or from
an alley, private road or driveway. The pavement striping designed to mark
the no-passing zone may be crossed from the left hand lane for the
purpose of completing a pass that was begun prior to the beginning of the
zone in the driver's direction of travel.
(d) Special speed limit areas required under Section 11-605 of this Code
in unincorporated areas only shall also be no-passing zones.

One-way roadways and rotary traffic islands.
(a) The Department and local authorities, with respect to highways under
their respective jurisdictions, may designate any highway, roadway, part of
a roadway or specific lanes upon which vehicular traffic shall proceed in
one direction at all or such times as shall be indicated by official
traffic control devices.
(b) Upon a roadway so designated for one-way traffic, a vehicle shall be
driven only in the direction designated at all or such times as shall be
indicated by official traffic control devices.
(c) A vehicle passing around a rotary traffic island must be driven only
to the right of such island.
(d) Whenever any highway has been divided into 2 or more roadways by
leaving an intervening space or by a physical barrier or a clearly
indicated dividing section so constructed as to impede vehicular traffic,
every vehicle must be driven only upon the right-hand roadway unless
directed or permitted to use another roadway by official traffic-control
devices or police officers. No vehicle may be driven over, across, or
within any such dividing space, barrier, or section, except through an
opening in the physical barrier, or dividing section, or space, or at a
cross-over or intersection as established by public authority.
(e) The driver of a vehicle may turn left across a paved noncurbed
dividing space unless prohibited by an official traffic-control device.

Driving on roadways laned for traffic.
Whenever any roadway has been divided into 2 or more clearly marked
lanes for traffic the following rules in addition to all others consistent
herewith shall apply.
(a) A vehicle shall be driven as nearly as practicable entirely within a
single lane and shall not be moved from such lane until the driver has
first ascertained that such movement can be made with safety.
(b) Upon a roadway which is divided into 3 lanes and provides for
two-way movement of traffic, a vehicle shall not be driven in the center
lane except when overtaking and passing another vehicle traveling in the
same direction when such center lane is clear of traffic within a safe
distance, or in preparation for making a left turn or where such center
lane is at the time allocated exclusively to traffic moving in the same
direction that the vehicle is proceeding and such allocation is designated
by official traffic control devices.
(c) Official traffic control devices may be erected directing specific
traffic to use a designated lane or designating those lanes to be used by
traffic moving in a particular direction regardless of the center of the
roadway and drivers of vehicles shall obey the directions of every such
device. On multi-lane controlled access
highways with 3 or more lanes in one
direction or on any multi-laned highway with 2 or more lanes in one
direction, the Department may designate lanes of traffic to be used by
different types of motor vehicles.
Drivers must obey lane designation signing except when it is necessary to
use a different lane to make a turning maneuver.
(d) Official traffic control devices may be installed prohibiting the
changing of lanes on sections of roadway and drivers of vehicles shall obey
the directions of every such device.

any other vehicle on the roadway adjacent to it.
(b) This Section shall not apply to any authorized emergency vehicle, to any authorized transit bus, to any farm tractor or implement of husbandry,
to any service vehicle while engaged in maintenance of the highway or
related work, or to any authorized vehicle within a designated construction zone.

drawing another vehicle
when traveling upon a roadway outside of a business or
residence district and which is following another truck or
motor vehicle drawing another vehicle shall,
whenever conditions permit, leave sufficient space so that
an overtaking vehicle may enter and occupy such space without
danger, except that this shall not prevent a truck or motor
vehicle drawing another vehicle from overtaking and passing
any vehicle or combination of vehicles.
(c) Motor vehicles being driven upon any roadway outside
of a business or residence district in a caravan or
motorcade whether or not towing other vehicles shall be so
operated as to allow sufficient space between each such
vehicle or combination of vehicles so as to enable any other
vehicle to enter and occupy such space without danger. This
provision shall not apply to funeral processions.

its jurisdiction may prohibit the use of any such highways by pedestrians
(except in authorized areas or facilities), bicycles, farm tractors,
implements of husbandry, funeral processions, and any vehicle unable to
maintain the minimum speed for which the highway is posted, or other
non-motorized traffic or by any person operating a motor driven cycle. The
Department may also prohibit the use of such highway to school buses
