304.341. 1. 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. -- The driver of a vehicle intending to turn left at any intersection shall approach the intersection in the extreme left-hand lane lawfully available to the 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 in a lane lawfully available to traffic moving in such direction upon the roadway being entered.
(3) The highways and transportation commission or local authorities in their respective jurisdictions may cause official traffic-control devices 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 such devices are so placed no driver of a vehicle shall turn a vehicle at any intersection other than as directed and required by such devices.
2. It shall be unlawful for the driver of any vehicle to turn such vehicle so as to proceed in the opposite direction at any intersection controlled by a traffic signal or police officer; nor shall such turn be made at any place unless the movement can be made in safety and without interfering with other traffic. The driver of a vehicle shall not turn such vehicle around so as to proceed in the opposite direction upon any curve or upon the approach to or near the crest of a grade, or at any place upon a roadway where such vehicle cannot be seen by the driver of any other vehicle approaching from either direction along the roadway within a distance of three hundred feet, or where the same may create a traffic hazard.
3. No vehicle in a residence district shall be turned left across the roadway or so as to proceed in the opposite direction when any other vehicle is approaching from either direction where the same may create a traffic hazard.
4. Notwithstanding the provisions of section 304.361, violation of this section is a class C misdemeanor.
