[Ord. No. 521, § 4-7, 7-27-1976]
(a) 
Whenever official traffic-control devices are placed in positions approximately conforming to the requirements of this chapter, such devices shall be presumed to have been so placed by the official act or direction of lawful authority, unless the contrary shall be established by competent evidence.
(b) 
Any official traffic-control device placed pursuant to the provisions of this chapter and purporting to conform to the lawful requirements pertaining to such devices shall be presumed to comply with the requirements of this chapter, unless the contrary shall be established by competent evidence.
[Ord. No. 521, § 4-9, 7-27-1976]
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.
[Ord. No. 521, § 4-1, 7-27-1976]
The City Engineer or any person authorized by the Board of City Commissioners shall place and maintain traffic-control signs, signals and devices when and as required under the traffic ordinances of this City to make effective the provisions of said ordinances, and may place and maintain such additional traffic-control devices as he may deem necessary to regulate traffic under the traffic ordinances of this City or under state law, or to guide or warn traffic.
[Ord. No. 521, § 4-7, 7-27-1976]
No provision of this chapter for which 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 state statute does not state that devices are required, such statute shall be effective even though no devices are erected or in place.
[Ord. No. 521, § 4-2, 7-27-1976]
All traffic-control signs, signals and devices shall conform to the specifications approved by the state highway commissioner pursuant to N.D.C.C. § 39-13-06. All signs and 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 state law or this article shall be official traffic-control devices.
[Ord. No. 521, § 4.8, 7-27-1976]
No person shall place, maintain or display upon or in view of any street any 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.
[Ord. No. 521, § 4-3, 7-27-1976]
In the event an official traffic-control signal is erected and maintained at a place other than an intersection, the provisions of § 10-83 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.
[Ord. No. 521, § 4-7, 7-27-1976]
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 traffic or police officer, subject to the exceptions granted the driver of an authorized emergency vehicle in this chapter.
[Ord. No. 521, § 4-3, 7-27-1976]
(a) 
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 or 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 for in § 10-85, 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 for in § 10-85, 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 at a clearly marked stop line, but if none, before entering the crosswalk on the near side of the intersection, or if none, then before entering the intersection and shall remain standing until an indication to proceed is shown, except as provided for in Subdivision b of this subsection.
b. 
Except when a sign is in place prohibiting a turn, vehicular traffic facing a 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 Subdivision a of this subsection. Such vehicular traffic shall yield the right-of-way to pedestrians lawfully within adjacent crosswalk and to other traffic lawfully using the intersection.
c. 
Unless otherwise directed by a pedestrian-control signal as provided for in § 10-85, pedestrians facing a steady red signal alone shall not enter the roadway.
[Ord. No. 521, § 4-4, 7-27-1976]
(a) 
Whenever an illuminated flashing red or yellow light is used in a traffic signal or with a traffic sign, 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 at a clearly marked stop line or, if none, before entering the crosswalk on the near side of the intersection or, if none, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway before entering it, 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 approaching railroad grade crossings shall be governed by the rules as set forth in § 10-181.
[Ord. No. 521, § 4-5, 7-27-1976]
(a) 
Whenever special pedestrian control signals exhibiting the words "Walk" or "Don't Walk" 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; and
(2) 
"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 island while the "Don't Walk" signal is showing.
[Ord. No. 521, § 4-6, 7-27-1976]
(a) 
The City Engineer or any person shall, when authorized by the Board of City Commissioners:
(1) 
Designate and maintain, by appropriate devices, marks or lines upon the surface of the roadway, crosswalks at intersections where there is particular danger to pedestrians crossing the roadway, and at such other places as directed by the board.
(2) 
Establish safety zones of such kind and character and at such places as may be deemed necessary for the protection of pedestrians as determined by the board.
(3) 
Mark traffic lanes upon the roadway of any street or highway where a regular alignment of traffic is necessary. Where such traffic lanes have been marked, it shall be unlawful for the operator of any vehicle to fail or refuse to keep such vehicle within the boundaries of any such lane except when lawfully passing another vehicle or preparatory to making a lawful turning movement or performing other lawful traffic movements.
