The City Traffic Engineer shall place and maintain traffic control
signs, signals and devices when and as required under the traffic
ordinances of the City to make effective the provisions of said ordinances
and may place and maintain such additional traffic control devices
as he/she may deem necessary to regulate traffic under the traffic
ordinances of the City or under State law or to guide or warn traffic.
All traffic control signs, signals and devices shall conform
to the manual and specifications approved by the State Highways and
Transportation Commission or resolution adopted by the Board of Aldermen
of the City. All signs or signals required hereunder for a particular
purpose shall so far as practicable be uniform as to type and location
throughout the City. All traffic control devices so erected and not
inconsistent with the provisions of this Title shall be official traffic
control devices.
The driver of any vehicle shall obey the instructions of any
official traffic control device applicable thereto placed in accordance
with the provisions of this Title, unless otherwise directed by a
traffic or Police Officer, subject to the exceptions granted the driver
of an authorized emergency vehicle in this Title.
No provision of this Title for which official traffic control
devices are required shall be enforced against an alleged violator
if at the time and place of the alleged violation an official device
is not in proper position and sufficiently legible to be seen by an
ordinarily observant person. Whenever a particular Section does not
state that official traffic control devices are required, such Section
shall be effective even though no devices are erected or in place.
Whenever traffic is controlled by traffic control signals exhibiting
different colored lights or colored lighted arrows, successively one
(1) 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 said lights shall indicate and apply to drivers of vehicles
and pedestrians as follows:
1. Green Indication.
a.
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. But 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.
b.
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.
c.
Unless otherwise directed by a pedestrian control signal as provided in Section
315.070, 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.
2. Steady Yellow Indication.
a.
Vehicular traffic facing a steady yellow signal is thereby warned
that the related green movement is being terminated or that a red
indication will be exhibited immediately thereafter when vehicular
traffic shall not enter the intersection.
b.
Pedestrians facing a steady yellow signal, unless otherwise directed by a pedestrian control signal as provided in Section
315.070, 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.
3. Steady Red Indication.
a.
Vehicular traffic facing a steady red signal alone shall stop
before entering the crosswalk on the near side of the intersection
or, if none, then before entering the intersection and shall remain
standing until a green indication is shown except as provided in paragraph
(b) of this Subsection.
b.
The driver of a vehicle which is stopped as close as practicable
at the entrance to the crosswalk on the near side of the intersection
or, if none, then at the entrance to the intersection in obedience
to a red signal may cautiously enter the intersection to make a right
turn but shall yield the right-of-way to pedestrians and other traffic
proceeding as directed by the signal at the intersection, except that
the State Highways and Transportation Commission with reference to
an intersection involving a State highway, and local authorities with
reference to an intersection involving other highways under their
jurisdiction, may prohibit any such right turn against a red signal
at any intersection where safety conditions so require, said prohibition
shall be effective when a sign is erected at such intersection giving
notice thereof.
c.
Unless otherwise directed by a pedestrian control signal as provided in Section
315.070, pedestrians facing a steady red signal alone shall not enter the roadway.
4. 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 those provisions which by their nature
can have no application. Any stop required shall be made at a sign
or marking on the pavement indicating where the stop shall be made,
but in the absence of any such sign or marking, the stop shall be
made at the signal.
Whenever special pedestrian control signals exhibiting the words
"Walk" or "Don't Walk" or appropriate symbols are in place, such
signals shall indicate as follows:
1. "WALK". Pedestrians facing such signal may proceed across the roadway
in the direction of the signal and shall be given the right-of-way
by the drivers of all vehicles.
2. "WAIT" or "DON'T WALK". No pedestrian shall start to cross the
roadway in the direction of such signal, but any pedestrian who has
partially completed his/her crossing on the walk signal shall proceed
to a sidewalk or safety zone while the wait signal is showing.
When lane direction control signals are placed over the individual
lanes of a street or highway, vehicular traffic may travel in any
lane over which a green signal is shown but shall not enter or travel
in any lane over which a red signal is shown.
No person shall place, maintain or display upon or in view of
any highway an unauthorized sign, signal, marking or device which
purports to be or is an imitation of or resembles an official traffic
control device or railroad sign or signal, or which attempts to direct
the movement of traffic, or which hides from view or interferes with
the effectiveness of any official traffic control device or any railroad
sign or signal.
No person shall without lawful authority attempt to or in fact
alter, deface, injure, knock down or remove any official traffic control
device or any railroad sign or signal or any inscription, shield or
insignia thereon or any other part thereof.
The City Traffic Engineer shall have authority to declare any
street or part thereof a play street and to place appropriate signs
or devices in the roadway indicating and helping to protect the same.
Whenever authorized signs are erected indicating any street
or part thereof as a play street, no person shall drive a vehicle
upon any such street or portion thereof except drivers of vehicles
having business or whose residences are within such closed area, and
then any said driver shall exercise the greatest care in driving upon
any such street or portion thereof.
The City Traffic Engineer is hereby authorized:
1. To designate and maintain, by appropriate devices, marks or lines
upon the surface of the roadway, crosswalks at intersections where
in his/her opinion there is particular danger to pedestrians crossing
the roadway and at such other places as he/she may deem necessary.
2. To establish safety zones of such kind and character and at such
places as he/she may deem necessary for the protection of pedestrians.
