Arizona Revised Statutes Title 28. Transportation § 28-771. Vehicle at intersection; exception; entering freeway

A. When two vehicles enter or approach an intersection from different streets or highways at approximately the same time, the driver of the vehicle on the left shall yield the right-of-way to the vehicle on the right. This subsection does not apply to vehicles approaching or entering an uncontrolled “T” intersection if the vehicle on the left is on a continuing street or highway and the vehicle on the right is on the terminating street or highway. The vehicle on the terminating street or highway shall yield to the vehicle on the continuing street or highway.

B. The right-of-way rule prescribed in subsection A of this section is modified at through highways and otherwise as stated in this article.

C. Intersecting road crossings between the main roadway of a freeway and acceleration lanes, ramps or any other approach roads are not intersections as defined in § 28-601, and subsection A of this section does not control questions of right-of-way at the crossings. A vehicle entering a freeway from an acceleration lane, a ramp or any other approach road shall yield the right-of-way to a vehicle on the main roadway of the freeway entering the merging area at the same time.
