What is the rule regarding right of way at stop signs?

The correct understanding of the rule regarding right of way at stop signs is that vehicles must stop at the stop sign and then yield to any vehicles that are already in the intersection. This means that if you approach a stop sign and there are other cars already present in the intersection, you must yield to them, allowing them to proceed before you can enter the intersection yourself. This rule helps to prevent collisions and ensures a systematic flow of traffic at intersections where visibility or traffic volume may create potential hazards.

Yielding to vehicles already in the intersection takes precedence over simply yielding to pedestrians or to vehicles on the right because it emphasizes the importance of preventing accidents at these critical junctions. Additionally, the rule about traffic on a main road having the right of way relates to different types of intersections and does not apply in this context, as the focus is specifically on the actions required at stop signs.
