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.

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.

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

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.
