§47-11-403.
   
   (a) Preferential right-of-way at an intersection may be indicated by
   stop signs or yield signs as authorized in Section 15-108 of this act.
   
   (b) Except when directed to proceed by a police officer or traffic
   control signal, every driver of a vehicle approaching a stop
   intersection indicated by a stop sign shall stop as required by
   Section 11-703(d) 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 said highway as
   to constitute an immediate hazard, but said 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) The driver of a vehicle 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 Section
   11-703(e), and shall yield the right-of-way to any pedestrian legally
   crossing the roadway on which he is driving, and to any vehicle in the
   intersection or approaching on another highway so closely as to
   constitute an immediate hazard. Said driver having so yielded may
   proceed and the drivers of all other vehicles approaching the
   intersection shall yield to the vehicle so proceeding, provided,
   however, that if such driver is involved in a collision with a
   pedestrian in a crosswalk or vehicle in the intersection after driving
   past a yield sign without stopping, such collision shall be deemed
   prima facie evidence of his failure to yield right of way.
   
   (d) Where two or more vehicles face stop, slow, warning or caution
   signs or signals on two or more intersecting cross streets, and are
   approaching so as to enter the intersection at the same time, where
   each vehicle is required to stop, the vehicle coming from the right
   shall have the right-of-way. Where each vehicle is required to slow
   the vehicle coming from the right shall have the right-of-way. Where
   each vehicle is required to take caution, the vehicle coming from the
   right shall have the right-of-way. Where one vehicle is required to
   stop and the other to slow or take caution, the one slowing or taking
   caution shall have the right-of-way. Where one vehicle is required to
   slow and the other to take caution, the one required to take caution
   shall have the right-of-way. In any event, a vehicle which has already
   entered the intersection shall have the right-of-way over one which
   has not so entered the intersection.
