(a) The driver of a vehicle shall stop as required by § 55-8-149 at the entrance to a through highway and shall yield the right-of-way to other vehicles which have entered the intersection from the through highway or which are approaching so closely on the through highway as to constitute an immediate hazard, but the driver having so yielded may proceed, and the drivers of all other vehicles approaching the intersection on the through highway shall yield the right-of-way to the vehicle so proceeding into or across the through highway.
(b) The driver of a vehicle shall likewise stop in obedience to a stop sign as required herein at an intersection where a stop sign is erected at one (1) or more entrances thereto although not a part of a through highway and shall proceed cautiously, yielding to vehicles not so obliged to stop which are within the intersection or approaching so closely as to constitute an immediate hazard, but may then proceed.
(c)

(1) The driver of a vehicle who is faced with a yield sign at the entrance to a through highway, drive, or other public roadway is not necessarily required to stop, but is required to exercise caution in entering the highway, drive, or other roadway and to yield the right-of-way to other vehicles which have entered the intersection from the highway, drive, or other roadway, or which are approaching so closely on the highway, drive, or other roadway as to constitute an immediate hazard, and the driver having so yielded may proceed when the way is clear.
(2) Where there is provided more than one (1) lane for vehicular traffic entering a through highway, drive, or other public roadway, if one (1) or more lanes at the entrance are designated a yield lane by an appropriate marker, this subsection (c) shall control the movement of traffic in any lane so marked with a yield sign, even though traffic in other lanes may be controlled by an electrical signal device or other signs, signals, markings or controls.
(d) As used in this section, “drive” and “intersection” have the same meanings as defined in § 55-8-128.
