What must drivers do at a stop sign?

Answer: B — Stop and give way to all other vehicles and pedestrians

At a stop sign, drivers are required to come to a complete stop and give way to all other vehicles and pedestrians. This rule is crucial for ensuring safety at intersections where visibility may be limited or where other road users are present. The stop sign indicates that the driver must pause to assess the situation, preventing potential accidents by allowing them to yield to any vehicles or pedestrians that may have the right of way. It's important to recognize that simply slowing down or continuing if clear does not ensure the necessary caution required at such intersections. Additionally, only stopping for pedestrians or ignoring the sign if no cars are coming disregards the fundamental traffic laws that prioritize safety and structured traffic flow for everyone on the road. Therefore, the requirement to stop and yield at a stop sign plays a vital role in maintaining order and preventing collisions.
