Whenever traffic is controlled by traffic signal indications exhibiting different colored lights successively one (1) at a time or with arrows, the following colors only shall be used and the lights shall indicate and apply to drivers of vehicles and pedestrians as follows:
1. 
Green indications shall allow the following:
a. 
Traffic, except pedestrians, facing a circular green may proceed straight through or turn right or left except as such movement is modified by lane use signs, turn prohibition signs, lane markings or roadway design. 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 indication is exhibited.
b. 
Traffic, except pedestrians, facing a green arrow, shown alone or in combination with another indication, may cautiously enter the intersection only to make the movement indicated by the 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 signal, pedestrians facing any green indication, except when the sole green indication is a turn arrow, may proceed across the roadway within any marked or unmarked crosswalk.
2. 
Steady yellow indications shall have the following meanings:
a. 
Traffic, except pedestrians, facing a steady circular yellow or yellow arrow signal is thereby warned that the movement allowed by green indications is being terminated and that a red indication will be exhibited immediately following the yellow indications at which point vehicular traffic shall not enter the intersection. No vehicle shall be in the intersection at the time the yellow indication is terminated and the red indication is begun.
b. 
Pedestrians facing a steady circular yellow or yellow arrow signal, unless otherwise directed by a pedestrian signal, 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 indications alone shall require the following:
a. 
Vehicular traffic facing a steady circular red signal alone shall stop at a clearly marked stop line, or as near to the line as previously stopped traffic will allow, before entering the intersection. If no stop line is present, drivers shall stop before entering the intersection. If a crosswalk is present on the near side of the intersection, drivers shall stop before entering the crosswalk. No vehicular traffic may enter the intersection until the signal allows such movement, except under the provisions of Section 315.110.
b. 
No pedestrian facing the signal shall enter the roadway until the green is shown alone, unless authorized so to do by a pedestrian "walk" signal.
c. 
Unless otherwise directed by a pedestrian signal, pedestrians facing a steady circular red or red arrow signal alone shall not enter the roadway.
4. 
Flashing signal indications shall have the following meanings:
a. 
Flashing red (stop signal). When a red lens is illuminated with intermittent flashes, drivers of vehicles shall stop at a clearly marked stop line. If a crosswalk is present at the near side of the intersection, drivers of vehicles shall stop before entering the crosswalk. The right to proceed shall be subject to the rules applicable after making a stop at a stop sign.
b. 
Flashing yellow (caution signal). When a yellow lens is illuminated with intermittent flashes, drivers of vehicles may proceed through the intersection or past such signal only with caution.
5. 
In the event a traffic 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.
6. 
After stopping as required by Subsection (3) above, vehicular traffic facing a steady red signal may cautiously enter the intersection to make a right turn unless a sign is erected prohibiting the movement. Vehicular traffic entering the intersection to make a right turn on the steady red signal shall yield the right-of-way to pedestrians and other traffic proceeding as directed by the signal at the intersection.
7. 
Any violation of this Section shall be deemed a misdemeanor.
[Order of 5-2-2009 §105.085]
A. 
Whenever pedestrian indications exhibiting the words or symbols for "walk" or "don't walk" are in place, the indications shall mean the following:
1. 
The "don't walk" indication or a symbol of a raised palm, steadily illuminated, means that a pedestrian shall not enter the roadway in the direction of the indication.
2. 
The "don't walk" indication or a symbol of a raised palm, while flashing, means that a pedestrian shall not start to cross the roadway in the direction of the indication, but that any pedestrian who has partly completed crossing during the steady "walk" indication shall proceed to a sidewalk or to a safety island.
3. 
A "walk" indication or symbol of a walking person, steadily illuminated, means that pedestrians facing the signal indication may proceed across the roadway in the direction of the indication.
B. 
Any violation of this Section shall be deemed a misdemeanor.
[Order of 5-2-2009 §105.090]
When lane direction control signal indications are placed over the individual lanes of a highway or roadway, vehicular traffic may travel in any lane over which a green signal indication is shown. Traffic shall not enter or travel in any lane over which a red indication is shown.

A. 
The driver of a vehicle intending to turn at an intersection shall do as follows:
1. 
Single lane right turns on roadways. Both the approach for a right turn and the right turn shall be made as close as practicable to the right-hand curb or edge of the roadway. When entering the intersection, the right turn shall be made so as to leave the intersection, as nearly as practicable, in the right-most lane lawfully available to traffic moving in the direction upon the roadway being entered.
2. 
Dual lane right turns on roadways. Where rights turns from two (2) lanes proceeding in the same direction are permitted by signs or pavement markings, the following action is required of drivers making right turns:
a. 
A driver turning from the outermost lane of the highway or roadway from which the driver is leaving shall make the turn into the outermost lane of the intersecting highway or roadway onto which the driver is entering.
b.

3. 
Single lane left turns on roadways. The driver of a vehicle intending to turn left at any intersection shall approach the intersection in the extreme left-hand lane lawfully available to traffic moving in the direction of travel of such vehicle. When entering the intersection, the left turn shall be made so as to leave the intersection, as nearly as practicable, in the left-hand lane lawfully available to traffic moving in the direction upon the roadway being entered. Whenever practicable, the left turn shall be made in that portion of the intersection to the left of the center of the intersection.
4. 
Dual lane left turns on roadways. Where left turns from two (2) lanes proceeding in the same direction are permitted by signs or pavement markings, the following action is required of drivers making left turns:
a.

b. 
A driver turning from the innermost lane of the highway or roadway from which the driver is leaving shall make the turn into the innermost lane of the intersecting highway or roadway onto which the driver is entering.
5. 
Two-way left turn lanes. Where two-way left turn lanes are designated by pavement markings and signs, drivers of vehicles traveling in either direction may, with caution, utilize these lanes to remove themselves from the traffic stream in preparation for executing left turns within five hundred (500) feet of having entered the lane. Such lanes shall not be used for overtaking or passing another vehicle when no left turning movement is made.
6. 
Any violation of this Section shall be deemed a misdemeanor.

Any violation of this Section shall be a misdemeanor.
[Order of 5-2-2009 §105.105]
A. 
The driver of a vehicle approaching an intersection from any highway, roadway or alleyway shall yield the right-of-way to any vehicle which has entered the intersection from a different highway, roadway or alleyway, absent other directions from a traffic control device or Law Enforcement Officer.
B. 
When two (2) vehicles enter an intersection from different highways, roadways or alleyways at approximately the same time, the driver on the left shall yield the right-of-way to the driver of the vehicle on the right. This Subsection shall not apply to vehicles approaching each other from opposite directions when the driver of one (1) vehicle is attempting to or is making a right turn.
C. 
The driver of a vehicle within an intersection intending to turn to the left shall yield the right-of-way to any vehicle approaching from the opposite direction which is within the intersection or so close to the intersection as to constitute an immediate hazard.
D. 
The driver of a vehicle intending to make a left turn into an alley, private road or driveway shall yield the right-of-way to any vehicle approaching from the opposite direction when the making of the left turn would create a traffic hazard.
E. 
The driver of a vehicle approaching a yield sign, as described in this Code, shall:
1. 
In obedience to the sign slow down to a speed reasonable for the existing conditions or shall stop if necessary and shall yield the right-of-way to any pedestrian crossing the roadway on which the vehicle is being driven. Said driver shall also yield to any vehicle in the intersection or approaching on another highway or roadway so closely as to constitute an immediate hazard. After yielding, said driver may proceed and the drivers of all other vehicles approaching the intersection shall yield to the vehicle so proceeding; provided however, that a driver who enters a yield intersection without stopping and has or causes a collision with a pedestrian in a crosswalk or a vehicle in the intersection shall prima facie be considered not to have yielded as required by this code. The foregoing shall not relieve the drivers of other vehicles approaching the intersection at such distance as not to constitute an immediate hazard from the duty to drive with due care to avoid a collision.
2. 
If required for safety to stop, stop before entering the crosswalk on the near side of the intersection. In the event there is no crosswalk, said driver shall stop at a clearly marked stop line, but if none, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway.
F. 
Every driver of a vehicle approaching a stop intersection indicated by a stop sign, as described in this Code, shall:
1. 
Except when directed to proceed by a Law Enforcement Officer or traffic signal, stop before entering the crosswalk on the near side of the intersection. In the event there is no crosswalk, the driver shall stop at a clearly marked stop line, but if none, then at the point nearest the intersecting roadway where a driver would have a view of approaching traffic on the intersecting roadway before entering the intersection.
2. 
After having stopped, yield the right-of-way to any vehicle which has entered the intersection from another roadway or which is approaching so closely on said roadway as to constitute an immediate hazard. Said driver having yielded may proceed and the drivers of all other vehicles approaching the intersection shall yield the right-of-way to the vehicle proceeding.
G. 
The driver of a vehicle emerging, either by forward motion or backing, from an alleyway, private roadway, driveway or building shall stop the vehicle immediately prior to driving onto a sidewalk or onto the sidewalk area and shall yield the right-of-way to any pedestrian as may be necessary to avoid collision. Upon entering the highway or roadway, the driver shall yield the right-of-way to all vehicles approaching on the highway or roadway.
H. 
No driver shall enter an intersection or a marked crosswalk unless there is sufficient space on the other side of the intersection or crosswalk to accommodate the vehicle the driver is operating without obstructing the passage of other vehicles or pedestrians, notwithstanding any traffic signal indication to proceed.
I. 
Any violation of this Section shall be a misdemeanor.

B. 
Any violation of this Section shall be a misdemeanor.
[Order of 5-2-2009 §105.115]
No driver shall operate a motor vehicle on any private lot, road, driveway, parking lot or any area which is not a roadway for the purpose of avoiding travel upon the right-of-way between one (1) highway or roadway and the same or another highway or roadway.

C. 
Upon a conviction or plea of guilty by any person for a moving violation as defined in Section 300.160 of the Jefferson County Traffic Code, the court shall assess a fine of thirty-five dollars ($35.00) in addition to any other fine authorized to be imposed by law, if the offense occurred within a construction zone or work zone.
D. 
Upon a conviction or plea of guilty by any person for a speeding violation pursuant to either Sections 315.010 or 315.030 of the Jefferson County Traffic Code or a passing violation pursuant to Subsection (F) of this Section, the court shall assess a fine of two hundred fifty dollars ($250.00) in addition to any other fine authorized by law, if the offense occurred within a construction zone or a work zone and at the time the speeding or passing violation occurred there was any person in such zone who was there to perform duties related to the reason for which the area was designated a construction zone or work zone. However, no person assessed an additional fine pursuant to this Subsection shall also be assessed an additional fine pursuant to Subsection (C) of this Section.

Violation of this Subsection shall be a misdemeanor punishable by a fine not to exceed three hundred dollars ($300.00).
[Order of 5-2-2009 §105.125]
