What must you do at a four-way stop?

Answer: B — Yield to the driver on your right if you arrive at the same time

At a four-way stop, when multiple vehicles arrive at the same time, the rule is to yield to the driver on your right. This is part of the right-of-way laws designed to promote safety and clarify the flow of traffic at intersections where visibility may be limited. Yielding to the driver on your right ensures that everyone knows how to proceed and reduces the likelihood of accidents by establishing a clear and predictable protocol. The other choices do not align with the established traffic rules. For example, yielding to the driver on the left contradicts the right-of-way principle and can create confusion at the intersection. Proceeding straight through without stopping disregards the necessity of yielding and can result in collisions with other vehicles that are also navigating the stop. Waiting for a signal from other drivers adds unnecessary complexity and could delay traffic flow, which the four-way stop is designed to manage efficiently.
