28-751. Required position and method of turning
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. The driver of a vehicle or combination of vehicles with a total length of at least forty feet or a total width of at least ten feet may deviate to the extent necessary from the lane into which the driver is making a right turn in a manner that avoids contact with another person or vehicle.
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. If practicable the driver shall make the left turn from the left of the center of the intersection and shall make the turn to the left lane immediately available for the driver's direction of traffic. The driver of a vehicle or combination of vehicles with a total length of at least forty feet or a total width of at least ten feet may deviate to the extent necessary from the lane into which the driver is making a left turn in a manner that avoids contact with another person or vehicle.
3. The director or local authorities in their respective jurisdictions may cause markers, buttons or signs to be placed and may require and direct that a different course from that specified in this section be traveled by vehicles turning at an intersection. When markers, buttons or signs are so placed, a driver of a vehicle shall not turn a vehicle other than as directed and required by the markers, buttons or signs.
4. Two-way left turn lanes. If a special lane for making left turns by drivers proceeding in opposite directions has been indicated by official traffic control devices:
(a) A driver shall not make a left turn from any other lane.
(b) A driver shall not drive a vehicle in the lane except if preparing for or making a left turn from or into the roadway or if preparing for or making a u-turn if otherwise permitted by law.
