10.7.103: POSITION AND METHOD OF TURNING:
A. Except where official markings or signs direct a different course, the driver of a vehicle intending to turn shall do so 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 right-hand curb or edge of the roadway.
2. Left Turns: The driver of a vehicle intending to turn left shall approach the turn in the extreme left-hand lane lawfully available to traffic moving in the direction of travel of the vehicle. Whenever practicable, the left turn shall be made to the left of the center of the intersection or other location so as to leave the intersection or other location in the extreme left-hand lane lawfully available to traffic moving in the same direction as the vehicle on the roadway being entered.
3. Two-Way Left Turn Lanes: Where a special lane for making left turns by drivers proceeding in opposite directions has been indicated by official traffic-control devices, a left turn shall not be made from any other lane, and a vehicle shall not be driven in the special lane except when preparing for or making a left turn from or into a roadway, driveway or alley, or when preparing for or making a U-turn when otherwise permitted by law.
B. At any intersection or other location designated by the City Traffic Engineer, and where authorized signs are erected and posted giving notice, turns may be made in the direction indicated by the signs from more than one lane of traffic as indicated by the signs. When any turn is so made the driver of the vehicle making the turn shall keep sufficient distance between the driver's vehicle and another vehicle turning in the same direction so as to avoid a collision, and shall enter the same lane of traffic on the street turned into as the vehicle was in on the street turned from, and no turn shall be made regardless of the posted signs permitting the same unless it can be done with safety. The driver making any turn shall give the appropriate signal as is required in making any other turn as provided for in this chapter.
C. Whenever a lane of traffic on any street or highway is designated by an official traffic-control device as a right or left turn only lane, it shall be unlawful for the driver of a vehicle in the lane to make any other movement at an intersection. (Ord. 83-317; Ord. 01-42)
