A. Preferential right-of-way at an intersection may be indicated by stop signs or yield signs as authorized in the Motor Vehicle Code [ 66-1-1 NMSA 1978].
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 66-7-345 C [NMSA 1978] 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 during the time when the driver is moving across or within the intersection.
C. The driver of a vehicle approaching a yield sign shall, in obedience to the sign, slow down to a speed reasonable for the existing conditions, and shall yield the right-of-way to any vehicle in the intersection or approaching on another highway so closely as to constitute an immediate hazard during the time the driver is moving across or within the intersection. If the driver is involved in a collision with a vehicle in the intersection, after driving past a yield sign without stopping, the collision shall be deemed prima facie evidence of his failure to yield right-of-way.
