The driver of a vehicle intending to turn at an intersection 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 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.
3. 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 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, as nearly as
practicable, in the left-hand lane lawfully available to traffic
moving in such direction upon the roadway being entered.
4. Local authorities in their respective jurisdictions may cause
markers, buttons or signs 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 markers, buttons or signs are so placed no
driver of a vehicle shall turn a vehicle at an intersection other than
as directed and required by such markers, buttons or signs.
