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 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.
The Chief of Police or his/her designee is authorized to place markers, buttons, or signs within or adjacent to intersections indicating the course to be traveled by vehicles turning at such intersections, and such course to be traveled as so indicated may conform to or be other than as prescribed by law or ordinance.
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.
The Chief of Police or his/her designee is hereby authorized to determine those intersections at which drivers of vehicles shall not make a right, left or U-turn, and shall place proper signs at such intersections. The making of such turns may be prohibited between certain hours of any day and permitted at other hours, in which event the same shall be plainly indicated on the signs or they may be removed when such turns are permitted.
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.
[CC 1961 §38.46; Ord. No. 109, 1-29-1941]
It shall be unlawful for the operator of any vehicle to turn such vehicle so as to proceed in the opposite direction, unless such movement can be made in safety and without backing or otherwise interfering with other traffic; but the operator of any vehicle shall not turn the vehicle so as to proceed in the opposite direction upon any street in a congested district designated in Schedule XI. The Director of Public Works shall post signs at all entrances to such congested districts indicating that such turns shall not be made.
