The driver of a vehicle intending to turn at an intersection shall do so as follows:
Right turns. Both the approach for a right turn and a right turn shall be made and completed as close as practicable to the right-hand curb or edge of the roadway, except where multiple turn lanes have been established.
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 centerline thereof and by passing to the right of such centerline 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 centerline 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.
Left turns on other than two-way roadways. At any intersection where traffic is restricted to one (1) direction on one (1) 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, except where multiple turn lanes have been established.
Designated two-way left turn lanes. Where a special lane for making left turns by drivers proceeding in opposite directions have been indicated by official traffic control devices:
A left turn shall not be made from any other lane;
A vehicle shall not be driven in the lane except when preparing for or making a left turn from or into the roadway or when preparing for or making a U-turn when otherwise permitted by law; and
A vehicle shall not be driven in the lane for a distance more than five hundred (500) feet.
When authorized markers, buttons or other indications are placed within an intersection indicating the course to be traveled by vehicles turning thereat, no driver of a vehicle shall disobey the directions of such indications.

Whenever authorized signs are erected indicating that no right or left or U-turn is permitted, no driver of a vehicle shall disobey the directions of any such sign.
Whenever authorized signs are erected specifically indicating that a right turn or left turn or U-turn is allowed, such turn is permitted provided such turn can be made safely, without interfering with other traffic and without conflict to any other traffic control device.

[R.O. 2008 §16-287; Ord. No. 977 §1(7.8), 1-5-1981]
No person shall turn a vehicle at any intersection or into an alley or a driveway or onto open land without first giving an appropriate signal for the required distance:
Right turn. A signal to turn right shall be given continuously during the last one hundred (100) feet traveled by the vehicle before turning right. Such signal shall be given either by signal lamp, mechanical signal device or by hand with arm extended upward from the left side of the vehicle by the driver. However, such signal shall be given only by signal lamp, lamps or mechanical devices by the driver of any vehicle if the distance from the center of the top of the steering post to the left outside limit of the body, cab or load of such vehicle exceeds twenty-four (24) inches or if the distance from the top of the steering post to other rear limit of the body or load of the vehicle exceeds fourteen (14) feet, whether a single vehicle or a combination of such vehicles; provided however, that this sentence shall not apply to any trailer which does not interfere with a clear view of the hand signals of the operator or of the signaling device upon the vehicle pulling said trailer; provided further, that the provisions of this sentence as far as mechanical devices on vehicles so constructed that a hand and arm signal would not be visible both to the front and rear of such vehicle as above provided shall only be applicable to new vehicles registered within this State after the first (1st) day of January, 1954.
Left turn. A signal to turn left shall be given continuously during the last one hundred (100) feet traveled by the vehicle before turning left. Such signal shall be given by signal lamp, lamps, mechanical signal device or by hand with arm extended horizontally from the left side of the vehicle by the driver. However, such signal shall be given only by signal lamp, lamps or mechanical signal device if the driver would be required to signal a right turn only by signal lamp, lamps or mechanical signal device under Subsection (1) above.
