Section 1160. Required position and method of turning at intersections

The
  driver of a vehicle intending to turn at an intersection shall do so  as
  follows:
    (a)  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  or,  where  travel  on  the  shoulder  or  slope  has been
  authorized, from the shoulder or slope.
    (b) Left turns on two-way roadways. At any intersection where  traffic
  is  permitted  to  move  in both directions on each roadway entering the
  intersection, an approach for a left turn shall be made in that  portion
  of  the right half of the roadway nearest the center line thereof and by
  passing  to  the  right  of  such  center  line  where  it  enters   the
  intersection  and after entering the intersection the left turn shall be
  made so as to leave the intersection to the right of the center line  of
  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.
    (c)  Left  turns  on  other than two-way roadways. At any intersection
  where traffic is restricted to one direction  on  one  or  more  of  the
  roadways,  the  driver  of  a vehicle intending to turn left at any such
  intersection shall approach the intersection in  the  extreme  left-hand
  lane  of  the  roadway  lawfully  available  to  traffic  moving  in the
  direction of travel of such vehicle or, where travel on the shoulder  or
  slope  has  been  authorized,  from  the  shoulder  or  slope, and after
  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 such direction upon the roadway being
  entered.
    (d) When markers, buttons, signs, or other markings are 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, no driver of a vehicle shall turn a
  vehicle  at  an intersection other than as directed and required by such
  markers, buttons, signs, or other markings.
    (e) U-turns. U-turns shall be made from and to  that  portion  of  the
  highway  nearest  the  marked center line. Where more than one lane of a
  highway has been designated for left turns, U-turns shall be  made  only
  from the lane so designated that is adjacent to the marked center line.
