(a) Preferential right-of-way at an intersection may be indicated by stop signs or yield signs as authorized by law.
(b) Except when directed to proceed by a police officer or traffic control signal, every driver of a vehicle and every operator of a streetcar approaching a stop intersection indicated by a stop sign shall stop as required by § 27-51-601, and after having stopped, shall yield the right-of-way to any vehicle which has entered the intersection from another highway or which is approaching so closely on the highway as to constitute an immediate hazard. The driver having so yielded may proceed, and the drivers of all other vehicles approaching the intersection shall yield the right-of-way to the vehicle so proceeding.
(c)
(1) The driver of a vehicle or the operator of a streetcar approaching a yield sign shall, in obedience to such sign, slow down to a speed reasonable for the existing conditions, or shall stop if necessary as provided in § 27-51-601, and shall yield the right-of-way to any pedestrian legally crossing the roadway on which he or she is driving. The driver shall also yield to any vehicle in the intersection or approaching on another highway so closely as to constitute an immediate hazard. A driver having so yielded may proceed, and the drivers of all other vehicles approaching the intersection shall yield to the vehicle so proceeding.
(2) If a driver is involved in a collision with a pedestrian in a crosswalk or a vehicle in the intersection after driving past a yield sign without stopping, the collision shall be deemed prima facie evidence of his or her failure to yield right-of-way.
