What does a stop sign mean?

Answer: B — Come to a complete stop and yield to traffic

A stop sign indicates that a driver must come to a complete stop at the intersection where the sign is posted. This action is crucial for ensuring safety by allowing drivers to observe cross traffic and any pedestrians before proceeding. Yielding to traffic means that upon stopping, a driver must check for oncoming vehicles or pedestrians who may have the right of way, ensuring that they can safely continue their journey. This rule helps prevent accidents and promotes orderly traffic flow at intersections. Other choices suggest lesser levels of stopping or conditions that might lead to confusion or unsafe practices. The focus of maintaining a complete stop is essential for all drivers to adhere to for the sake of overall road safety.
