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.

Traffic-control signal legend.
Whenever traffic is controlled
by traffic-control signals exhibiting different colored lights or color
lighted arrows, successively one at a time or in combination, only the
colors green, red and yellow shall be used, except for special pedestrian
signals carrying a word legend, and the lights shall indicate and apply to
drivers of vehicles and pedestrians as follows:
(a) Green indication.
1. Vehicular traffic facing a circular green signal
may proceed straight through or turn right or left unless a sign at such place prohibits either such turn. Vehicular traffic, including vehicles turning right or left, shall yield the right of way to other vehicles and to pedestrians lawfully within the intersection or an adjacent crosswalk at the time such signal is exhibited.
2. Vehicular traffic facing a green arrow signal,
shown alone or in combination with another indication, may cautiously enter the intersection only to make the movement indicated by such arrow, or such other movement as is permitted by other indications shown at the same time. Such vehicular traffic shall yield the right of way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.
3. Unless otherwise directed by a pedestrian-control
signal, as provided in Section 11-307, pedestrians facing any green signal, except when the sole green signal is a turn arrow, may proceed across the roadway within any marked or unmarked crosswalk.
(b) Steady yellow indication.
1. Vehicular traffic facing a steady circular yellow
or yellow arrow signal is thereby warned that the related green movement is being terminated or that a red indication will be exhibited immediately thereafter.
2. Pedestrians facing a steady circular yellow or
yellow arrow signal, unless otherwise directed by a pedestrian-control signal as provided in Section 11-307, are thereby advised that there is insufficient time to cross the roadway before a red indication is shown and no pedestrian shall then start to cross the roadway.
(b-5) Flashing yellow arrow indication.
1. Vehicular traffic facing a flashing yellow arrow
indication may cautiously enter the intersection only to make the movement indicated by the arrow and shall yield the right-of-way to other vehicles and pedestrians lawfully within the intersection or an adjacent crosswalk at the time the signal is exhibited.
2. Pedestrians facing a flashing yellow arrow
indication, unless otherwise directed by a pedestrian-control signal as provided in Section 11-307, may proceed across the roadway within any marked or unmarked crosswalk that crosses the lane or lanes used to depart the intersection by traffic controlled by the flashing yellow arrow indication. Pedestrians shall yield the right-of-way to vehicles lawfully within the intersection at the time that the flashing yellow signal indication is first displayed.
(c) Steady red indication.
1. Except as provided in paragraphs 3 and 3.5 of this
subsection (c), vehicular traffic facing a steady circular red signal alone shall stop at a clearly marked stop line, but if there is no such stop line, before entering the crosswalk on the near side of the intersection, or if there is no such crosswalk, then before entering the intersection, and shall remain standing until an indication to proceed is shown.
2. Except as provided in paragraphs 3 and 3.5 of this
subsection (c), vehicular traffic facing a steady red arrow signal shall not enter the intersection to make the movement indicated by the arrow and, unless entering the intersection to make a movement permitted by another signal, shall stop at a clearly marked stop line, but if there is no such stop line, before entering the crosswalk on the near side of the intersection, or if there is no such crosswalk, then before entering the intersection, and shall remain standing until an indication permitting the movement indicated by such red arrow is shown.
3. Except when a sign is in place prohibiting a turn
and local authorities by ordinance or State authorities by rule or regulation prohibit any such turn, vehicular traffic facing any steady red signal may cautiously enter the intersection to turn right, or to turn left from a one-way street into a one-way street, after stopping as required by paragraph 1 or paragraph 2 of this subsection. After stopping, the driver shall yield the right of way to any vehicle in the intersection or approaching on another roadway so closely as to constitute an immediate hazard during the time such driver is moving across or within the intersection or junction or roadways. Such driver shall yield the right of way to pedestrians within the intersection or an adjacent crosswalk.
3.5. In municipalities with less than 2,000,000
inhabitants, after stopping as required by paragraph 1 or 2 of this subsection, the driver of a motorcycle or bicycle, facing a steady red signal which fails to change to a green signal within a reasonable period of time not less than 120 seconds because of a signal malfunction or because the signal has failed to detect the arrival of the motorcycle or bicycle due to the vehicle's size or weight, shall have the right to proceed, after yielding the right of way to oncoming traffic facing a green signal, subject to the rules applicable after making a stop at a stop sign as required by Section 11-1204 of this Code.
4. Unless otherwise directed by a pedestrian-control
signal as provided in Section 11-307, pedestrians facing a steady circular red or red arrow signal alone shall not enter the roadway.
(d) In the event an official traffic control signal is
erected and maintained
at a place other than an intersection, the provisions of this Section shall
be applicable except as to provisions which by their nature can have no
application. Any stop required shall be at a traffic sign or a marking
on the pavement indicating where the stop shall be made or, in the absence
of such sign or marking, the stop shall be made at the signal.
(e) The motorman of any streetcar shall obey the above signals as applicable
