What must drivers do at a four-way stop according to Title 21?

At a four-way stop, the rules establish a clear protocol to ensure safety and efficiency in traffic flow. The correct response highlights the necessity for drivers to yield to the vehicle on their right when two or more vehicles arrive at the intersection simultaneously. This rule helps to reduce confusion and the potential for accidents, as it provides a definitive guideline for determining who has the right of way in situations where multiple drivers are seeking to proceed.

Understanding the reasoning behind this rule is crucial. It creates an orderly process for vehicles interacting at a four-way stop, where the line of sight and the positioning of the vehicles play a significant role in decision-making. By yielding to the right, drivers can make informed decisions, reducing hesitation and the likelihood of collisions, which can occur if drivers try to assert the right of way without clear guidelines.

The other options fail to capture this essential aspect of traffic rules at four-way stops. For instance, while it is important to give way to pedestrians and to come to a complete stop if there are no other vehicles, these actions do not address the specific scenario of simultaneous arrivals at the intersection, which is where the right-hand yield rule applies. Thus, recognizing the priority given to vehicles on one's right enhances overall traffic safety and compliance with Title
