§47-11-604.
   
   A. No person shall turn a vehicle at an intersection, a public or
   private road, or a driveway, unless the vehicle is in proper position
   upon the roadway as required in Section 11-601 of this title, or move
   right or left upon a roadway unless and until such movement can be
   made with reasonable safety. No person shall so turn any vehicle
   without giving an appropriate signal as provided in subsection B of
   this section, in the event any other traffic may be affected by such
   movement.
   
   B. A signal of intention to turn right or left as required by law
   shall be given continuously during not less than the last one hundred
   (100) feet traveled by the vehicle before turning.
   
   C. No person shall stop or suddenly decrease the speed of a vehicle
   without first giving an appropriate signal in the manner provided in
   subsection B of this section to the driver of any vehicle immediately
   to the rear when there is opportunity to give such signal.
   
   D. When any person is properly preparing for, attempting or executing
   a left turn, as described in subsection A of this section, no other
   person operating another vehicle immediately following the turning
   vehicle shall pass or attempt to pass the turning vehicle to the left.
   Such other person shall come to a complete stop if necessary at a safe
   distance behind the person preparing for, attempting or executing the
   turn or may proceed to the right of the turning vehicle as provided by
   Section 11-304 of this title.
