What is indicated by a stop sign?

A stop sign indicates that a driver must come to a complete stop at the intersection. After stopping, the driver must yield to all traffic and pedestrians before proceeding. This ensures that the driver has enough time to assess the situation at the intersection and makes safe decisions regarding their next move. Yielding after stopping is crucial as it allows other vehicles or pedestrians who may have the right-of-way to move safely.

The other choices do not convey the full requirements of a stop sign; merely slowing down or proceeding if the road is clear does not prioritize safety in the same way that coming to a complete stop and yielding does. Stopping for pedestrians alone does not provide enough attention to other vehicles that may also be in or approaching the intersection. Therefore, the only responsible action when encountering a stop sign is to stop completely and yield to all surrounding traffic and pedestrians.
