Does a driver who has a yield sign at an intersection have to yield?

In the state of Arkansas the law says that a driver must stop at a yield sign ONLY if required for safety.

In the general rules of the road the person with the stop sign must first stop and THEN yield to others approaching the intersection; the person with the yield sign is only obligated to stop if others are "approaching." If another car is stopped at the stop sign, it is not "approaching" the intersection. If it is not stopped, then it is certainly approaching, and you would have to yield to the car on the right, even if the driver is breaking the law by not stopping! This is the general rule of not taking priority when you cannot do so safely.
