Cross Reference — As to prohibited left and right turns, sch. IV.
[CC 1970 §21-85; CC 1947 §11-57]
A. 
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, except where multiple turn lanes have been established.
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 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.
3. 
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.
4. 
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. 
A left turn shall not be made from any other lane;
b. 
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
c. 
A vehicle shall not be driven in the lane for a distance more than five hundred (500) feet.
B. 
The operator of a vehicle shall not drive through private property or other open way to circumvent either a stop sign or stop light.
A. 
No person shall stop or suddenly decrease the speed of or turn a vehicle from a direct course or move right or left upon a roadway unless and until such movement can be made with reasonable safety and then only after the giving of an appropriate signal in the manner provided herein.
1. 
An operator or driver when stopping, or when checking the speed of the operator's vehicle if the movement of other vehicles may reasonably be affected by such checking of speed, shall extend such operator's arm at an angle below horizontal so that the same may be seen in the rear of the vehicle.
2. 
An operator or driver intending to turn the vehicle to the right shall extend such operator's arm at an angle above horizontal so that the same may be seen in front of and in the rear of the vehicle and shall slow down and approach the intersecting highway as near as practicable to the right side of the highway along which such operator is proceeding before turning.
3. 
An operator or driver intending to turn the vehicle to the left shall extend such operator's arm in a horizontal position so that the same may be seen in the rear of the vehicle and shall slow down and approach the intersecting highway so that the left side of the vehicle shall be as near as practicable to the centerline of the highway along which the operator is proceeding before turning.
4. 
The signals herein required shall be given either by means of the hand and arm or by a signal light or signal device in good mechanical condition of a type approved by the State Highway Patrol; however, when a vehicle is so constructed or loaded that a hand and arm signal would not be visible both to the front and rear of such vehicle, then such signals shall be given by such light or device. A vehicle shall be considered as so constructed or loaded that a hand and arm signal would not be visible both to the front and rear when the distance from the center of the top of the steering post to the left outside limit of the body, cab or load exceeds twenty-four (24) inches, or when the distance from the center of the top of the steering post to the rear limit of the body or load thereon exceeds fourteen (14) feet, which limit of fourteen (14) feet shall apply to single vehicles or combinations of vehicles. The provisions of this Subsection 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 such trailer; provided further, that the provisions of this Section 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.

A. 
It shall be unlawful for the operator of any vehicle to make a U-turn or otherwise turn such vehicle within any roadway or intersection 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, provided, however, that the operator of any vehicle shall not make a U-turn or otherwise turn the same so as to proceed in the opposite direction upon:
1. 
Brentwood Boulevard;
2. 
Hanley Road;
3. 
Within the area bounded on the north by the north side of Maryland Avenue, on the west by the west side of Brentwood Boulevard, on the south by the south side of Forest Park Expressway and on the east by the east side of Hanley Road except from 9:00 P.M. to 6:30 A.M. and on Saturdays, Sundays and legal holidays;
