[Code 1980 §15-179; CC 1990 §15-401]
A. 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.
B. Traffic
signals shall be installed at the street intersections enumerated
by Schedule I and hereafter duly enacted by the Council of the City.
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 legislative
body 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.
[Code 1980 §15-183; CC 1990 §15-405]
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.
[Code 1980 §15-185; CC 1990 §15-407]
No provisions 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 traffic
control 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 official traffic control
devices are erected or in place.
[Code 1980 §15-180; CC 1990 §15-402]
A. 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 such 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 of this Code, 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 of this Code, 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 Subsection
(b) of this Subsection
(3).
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 the City with reference
to an intersection involving other highways under its jurisdiction,
may prohibit any such right turn against a red signal at any intersection
where safety conditions so require, such 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.
B. If
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.
[Code 1980 §15-182; CC 1990 §15-404]
A. Whenever
an illuminated flashing red or yellow signal is used in a traffic
sign or signal, it shall require obedience by vehicular traffic as
follows:
1. Flashing red (stop signal). When a red lens is illuminated
with rapid intermittent flashes, drivers of vehicles shall stop before
entering the nearest crosswalk at an intersection or at a limit line
when marked or, if none, then before entering the intersection, and
the right to proceed shall be subject to the rules applicable after
making a stop at a stop sign.
2. Flashing yellow (caution signal). When a yellow
lens is illuminated with rapid intermittent flashes, drivers of vehicles
may proceed through the intersection or past such signal only with
caution.
B. This
Section shall not apply at railroad grade crossings. Conduct of drivers
of vehicles approaching railroad grade crossings shall be governed
by the rules as set forth in Section 300.295, RSMo.
[Code 1980 §15-184; CC 1990 §15-406]
When a traffic control device or signal is not operating through
mechanical failure or for other reasons, all traffic shall come to
a complete stop before operating onto or through the intersection.
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.
[Code 1980 §15-187; CC 1990 §15-409]
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.
