The City Traffic Engineer shall place and maintain traffic control
signs, signals, and devices when and as required under the provisions
of this chapter and other ordinances of the City to make effective
such provisions, and he may place and maintain such additional traffic
control devices as he may deem necessary to regulate traffic under
the provisions of this chapter or other ordinances of the City or
under state law or to guide or warn traffic.
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 chapter, unless otherwise directed by
a police officer, subject to the exceptions granted the driver of
an authorized emergency vehicle in this chapter.
No provision of this chapter 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.
[Ord. No. 7920, § 1, 10-19-1989]
Whenever traffic is controlled by traffic control signals exhibiting
different colored lights or colored 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. 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.
(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 this article, 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 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.
(2)
Pedestrians facing a steady yellow signal, unless otherwise
directed by a pedestrian control signal as provided in this article,
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.
(c) Steady red indication.
(1)
Vehicular traffic facing a steady red signal alone shall stop
before entering the crosswalk on the near side of the intersection
at a clearly marked stop line, but if none, then before entering the
intersection, and shall remain standing until an indication to proceed
is shown, except as provided in Subsection (c)(2);
(2)
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;
(3)
Unless otherwise directed by a pedestrian control signal as provided in §
14-279, pedestrians facing a steady red signal alone shall not enter the roadway.
(d) Traffic control signals, signs or markings at other than intersections.
In the event an official traffic control signal is erected and maintained
at a place other than an intersection, the provision 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:
(a) 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.
(b) 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 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.
Pedestrians shall be subject to traffic control signals as prescribed in §§
14-278 and
14-279, but at all other places pedestrians shall be granted those rights and be subject to the restrictions stated in this article.
No pedestrian shall suddenly leave a curb or other place of
safety and walk or run into the path of a vehicle which is so close
that it is impossible for the driver to yield the right-of-way.
Pedestrians shall move, whenever practicable, upon the right
half of crosswalks.
No pedestrian shall cross a roadway at any place other than
by a route at right angles to the curb or by the shortest route to
the opposite curb, except in a crosswalk.
