What must drivers do when approaching a stop sign?

Answer: B — Stop completely and yield to pedestrians and traffic

When approaching a stop sign, drivers are required to come to a complete stop and yield to any pedestrians and other traffic that may have the right of way. This practice ensures that all road users can safely navigate the intersection. Stopping completely allows drivers to assess their surroundings thoroughly, making it safer for pedestrians crossing the street and other vehicles that may approach from different directions. It's important to note that simply reducing speed or proceeding without stopping could lead to accidents, as drivers might misjudge the traffic situation or fail to notice pedestrians. Accelerating to pass the sign quickly disregards the rules of safe driving and could endanger both the driver and others on the road. Ignoring the sign altogether, even if traffic appears clear, poses a serious risk since it eliminates the necessary caution required at intersections where sudden changes in traffic flow can occur. By stopping completely, all users of the roadway can contribute to a safer driving environment.
