Arizona Revised Statutes Title 28. Transportation § 28-855. Stop signs; yield signs

A. The director, with reference to state highways, and local authorities, with reference to other highways under their jurisdiction, may designate through highways and erect stop or yield signs at specified entrances to the through highways or may designate an intersection as a stop or yield intersection and erect like signs at one or more entrances to the intersection.

B. A driver of a vehicle approaching a stop sign shall stop before entering the crosswalk on the near side of the intersection, or if there is no crosswalk, shall stop at a clearly marked stop line, or if there is no line, shall stop at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway before entering the intersection except when directed to proceed by a police officer.

C. The driver of a vehicle approaching a yield sign shall slow down in obedience to the sign 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 after driving past a yield sign without stopping the driver is involved in a collision with a vehicle in the intersection, the collision is prima facie evidence of the driver's failure to yield the right-of-way.
