A. 
The driver of a vehicle intending to turn at an intersection shall do as follows:
1. 
Right turns. Both the approach for a right turn and a right turn shall be made as close as practicable to the righthand curb or edge of the roadway. Compliance with this subsection shall be determined with due regard to the length of the vehicle and its turning radius capabilities.
2. 
Left turns. The driver of a vehicle intending to turn left at any intersection shall approach the intersection in the extreme lefthand lane lawfully available to traffic moving in the direction of travel of such vehicle and, after entering the intersection, the left turn shall be made so as to leave the intersection in the left-most lane lawfully available to traffic moving in such direction upon the roadway being entered. Whenever practicable, the left turn shall be made in that portion of the intersection to the left of center of the intersection.
3. 
Turning movements specified by traffic control devices. The municipal traffic engineer may cause official traffic control devices to be placed within or adjacent to intersections and thereby require and direct that a different course from that specified in this section be traveled by vehicles turning at an intersection, and when such devices are placed no driver of a vehicle may turn the vehicle at an intersection other than as directed and required by such devices, unless directed to do so by a police officer.
a. 
If traffic control devices are installed at or adjacent to an intersection permitting left turns from more than one lane, vehicles which turn left shall depart the intersection in the same relative lane in which they entered the intersection and shall remain in such lane for a reasonable distance.
b. 
If traffic control devices are installed at or adjacent to an intersection permitting right turns or left turns from more than one lane, vehicles making such turns shall depart the intersection in the same relative lane position as that in which they entered the intersection, and shall remain in such lane for a reasonable distance.
(CAC 9.22.010; AO No. 78-72; AO No. 2011-113(S), § 45, 11-22-2011, eff. 12-22-2011)
A. 
The traffic engineer of the state or the municipality may designate a two-way left-turn lane on a roadway. A two-way left-turn lane is a lane near the center of the roadway, set aside for the use by vehicles making left turns in both directions from the roadway.
B. 
Two-way left-turn lanes shall be designated by distinctive roadway markings consisting of parallel double yellow lines, the interior line dashed and the exterior line solid, on each side of the lane. The markings shall conform to the standards set forth in the Manual on Uniform Traffic Control Devices.
C. 
A vehicle shall not be driven in a designated two-way left-turn lane except when preparing for or making a left turn from the roadway, or when preparing for or making a turn in the opposite direction when otherwise permitted by law. A left turn or turn in the opposite direction shall not be made from any other lane where a two-way left-turn lane has been designated.
D. 
A vehicle shall not be driven in excess of 150 feet in any designated two-way left-turn lane.
E. 
This section shall not prohibit driving across a two-way left-turn lane.
(AO No. 89-52)
A. 
No person may start or place in motion a vehicle which is stopped, standing or parked unless and until such movement can be made with reasonable safety.
B. 
No person may accelerate a vehicle which is stopped, standing or parked on or along a street, or which is entering a street, so rapidly as to unnecessarily cause the tires to squeal or spin on the street, or on the surface on which the vehicle is standing immediately before it enters the street, or in a manner which causes the driver to lose control of the vehicle or causes the vehicle to "fishtail."
(CAC 9.22.030; AO No. 78-72; AO No. 80-4)
A. 
No person may turn a vehicle at an intersection unless the vehicle is in proper position upon the roadway as required in section 9.22.010, or turn a vehicle to enter a private road or driveway, or otherwise turn a vehicle from a direct course or move right or left upon a roadway, unless and until such movement can be made with reasonable safety. No person may so turn any vehicle without giving an appropriate signal in the manner provided in this section.
B. 
A signal of intention to turn right, turn left, or change lanes shall be given continuously during not less than the last 100 feet traveled by the vehicle before the turning movement or lane change.
C. 
No person may stop or suddenly decrease the speed of a vehicle without first giving an appropriate signal in the manner provided in this section to the driver of any vehicle immediately to the rear when there is opportunity to give such a signal.
D. 
The signals as set forth in section 9.22.060 shall be used to indicate an intention to turn, change lanes, or start from a parked position and shall not be flashed on one side only on a parked or disabled vehicle or flashed as a courtesy or "do pass" signal to operators of other vehicles approaching from the rear.
(CAC 9.22.040; AO No. 38-75; AO No. 78-72; AO No. 94-68(S), § 9, 8-11-1994)
Should the driver of any vehicle give or cause to be given any signal which would indicate to other traffic the driver's intention to turn, the driver must not fail to make such turn nor fail to yield the right-of-way to all other traffic that would be affected by the driver's failure to complete such indicated turn.
(CAC 9.22.050; AO No. 78-72; AO No. 2011-113(S), § 46, 11-22-2011, eff. 12-22-2011)
A. 
Any stop or turn signal, when required in this chapter, shall be given either by means of the hand and arm or by signal lamps, except as otherwise provided in subsection B of this section.
B. 
Any motor vehicle in use on a street shall be equipped with, and required signals shall be given by, signal lamps when the distance from the center of the top of the steering post of the left outside limit of the body, cab or load of such motor vehicle exceeds 24 inches, or when the distance from the center of the top of the steering post to the rear limit of the body load thereof exceeds 14 feet. The latter measurement shall apply to any single vehicle and to any combination of vehicles.
(CAC 9.22.060; AO No. 78-72)
All signals required in this chapter to be given by hand and arm shall be given from the left side of the vehicle in the following manner and such signals shall indicate as follows:
A. 
Left turn: hand and arm extended horizontally.
B. 
Right turn: hand and arm extended upward.

A. 
The municipal traffic engineer is authorized to determine those intersections at which drivers of vehicles shall not make a right turn, left turn or U-turn and shall place proper signs at such intersections. The making of such turns may be prohibited during certain hours of any day and permitted at other hours, in which event such hours shall be plainly indicated on the signs, or the signs may be removed when such turns are permitted.
B. 
Whenever authorized signs are erected indicating that no right turn or left turn or U-turn is permitted, no driver of a vehicle may disobey the directions of any such signs.
(CAC 9.22.080; AO No. 78-72)
A. 
No vehicle shall be turned around so as to proceed in the opposite direction as follows:
